Obtaining a CPR number

The CPR number, or Det Centrale Personregister, is a key element of the Danish administrative system, acting as a unique identifier for every person registered in Denmark. As a central element of the population register, the CPR number is essential to function in Denmark, both in everyday life and in dealing with authorities. It enables effective identification of citizens and residents, which is important for the proper management of social, health and tax services.

What is worth knowing about the CPR number?

In Denmark, the CPR number, or Det Centrale Personregister, is pretty much your personal ID number. It’s a must-have for everyone registered in the country.

Here’s the lowdown on the CPR number:

I. What’s it for?: The CPR number is like your official badge in the Danish system. It helps identify people living here, making it easier for the government to manage everything from social services to healthcare.

II. Where do you use it?: You’ll need this number for all kinds of things, like filing your taxes, getting health benefits, and dealing with public offices. It really keeps everything organized.

III. How do you get one?: If you’re planning to stay in Denmark, whether it’s for a while or just a bit, you’ll get a CPR number. You can usually sign up online, or if you prefer, you can visit your local municipality office for help.

IV. What does it look like?: The CPR number is made up of 10 digits. The first six represent your birth date (day, month, year), while the last four are unique to you. Plus, there are “check digits” to ensure it’s accurate.

V. Your privacy counts: Because it’s so important, your CPR number is protected by data privacy laws. This means you have rights about who can access your info and how it’s used.

The process of obtaining a CPR number in Denmark

Getting a CPR number in Denmark involves a few important steps:

1. Register your residence: First things first, you need to have either permanent or temporary registration in Denmark. Only those registered in the Danish resident registration system can get a CPR number.

2. Apply:

- Online: Applying online is a breeze! It makes the process much easier, so you won’t have to visit any offices. The application fee is about DKK 82. If you’re not able to go online, don’t worry! Local officials can help you fill out and submit your documents at municipal offices, and public libraries usually have computers with internet access.

- In-person: If online isn’t an option for you, just swing by your local municipality office to apply.

3. Gather your documents: When you apply, make sure you have the following documents ready, and they should be translated into English, German, Danish, Swedish, or Norwegian:

- your passport or ID card,

- proof of residence in Denmark (like a rental agreement),

- proof of employment (an employment contract works),

- your residence permit,

- if applicable, your marriage certificate, or documents related to divorce or the death of a spouse,

- children’s birth certificates if they’ve moved with you.

4. Apply on someone else’s behalf: If you’re helping someone else get their CPR number, you’ll need a written proxy that allows you to act on their behalf.

5. Obtain your number:

- Waiting time: Usually, you’ll receive your CPR number from SKAT within 6 to 10 weeks after you submit all your documents.  

- Certificate: If you applied online, you’ll get a reference number from the International Center for Foreigners in Copenhagen, which you’ll need to pick up in person. If you’re outside of Copenhagen, you can apply at Foreigners' Centers in Odense, Aarhus, or Aalborg.

Next steps after getting your CPR number:

- Health insurance: With your CPR number, you automatically join the Danish health insurance system and can access medical services. Your municipality will provide a list of doctors for you to choose from.

- Setting up a tax card: Your CPR number is also your ticket to starting the process of getting a tax card.

- Employer notification: Your CPR number will be on your first annual tax return. SKAT will send your tax ID number to your employer via digital mail, which helps them calculate your income tax payments correctly. 

You can get your tax identification number up to a month before you start working in Denmark. If you’ve lived or worked in Denmark before, there’s a chance you might already have a CPR number.

Types of CPR numbers: temporary vs. permanent and what they mean for you

The Danish CPR system distinguishes between a permanent CPR number and a temporary CPR number. Understanding the difference is crucial, because the type of CPR you receive directly affects your access to healthcare, tax registration, banking, digital services (MitID), and many other practical aspects of life in Denmark.

What is a permanent CPR number?

A permanent CPR number is a lifelong personal identification number assigned to you when you are registered as residing in Denmark in the Civil Registration System (CPR). In practice, this usually means you have:

• a valid basis for residence in Denmark (for example, EU right of residence, work or study permit, family reunification, or permanent residence), and
• a registered address in Denmark (folkeregister address).

Once issued, a permanent CPR number does not expire and is not changed if you later move abroad or change your residence status. It is used for all official purposes, including tax, healthcare, social benefits, pensions, banking, and contracts.

A permanent CPR number normally gives you:

• full access to the Danish public healthcare system (assignment to a general practitioner and a yellow health insurance card)
• automatic registration in the tax system (SKAT) so your employer can withhold the correct tax
• the possibility to obtain MitID and a digital mailbox (e-Boks)
• easier access to Danish banks, mobile phone contracts, and housing contracts

What is a temporary CPR number?

A temporary CPR number is a personal identification number given to people who need to be identified in Danish systems but do not meet the conditions for a permanent registration in the Civil Registration System. It is sometimes called a “tax number” or “administrative CPR” and is typically used for:

• short-term workers or posted workers who work in Denmark but do not move their official residence here
• cross-border workers who live in another country but pay tax in Denmark
• people who need to pay tax in Denmark on specific income (for example, fees, royalties, or board memberships)
• some non-residents who need to interact with Danish authorities or financial institutions

A temporary CPR number is usually created by the Danish Tax Agency (SKAT) or another authority for administrative purposes. It allows the authorities to register your income, tax, and certain rights or obligations, but it does not give you the same level of access to services as a permanent CPR number.

Key differences between temporary and permanent CPR numbers

Although both numbers look similar and are used to identify you, they are not equal in practice. The most important differences are:

• Residence status
  A permanent CPR number is linked to an official registered address in Denmark and a valid basis for residence. A temporary CPR number is usually linked to non-resident or limited-resident status.
• Healthcare
  With a permanent CPR number and a registered address, you are normally entitled to full public healthcare and receive a yellow health insurance card. With a temporary CPR number, you are often not assigned a general practitioner and may have limited or no access to the public healthcare system, depending on your specific situation and EU/EEA agreements.
• Taxation
  Both types of CPR numbers can be used for tax purposes. However, with a permanent CPR number you are usually considered fully tax liable in Denmark (unlimited tax liability), whereas with a temporary CPR number you are often taxed on specific Danish income only (limited tax liability). The exact rules depend on your residence and double taxation agreements.
• Digital services (MitID, e-Boks)
  A permanent CPR number with a registered address makes it much easier to obtain MitID and a digital mailbox, which are required for most communication with Danish authorities and many private companies. With a temporary CPR number, access to MitID can be more limited and may require additional documentation or may not be possible in some cases.
• Banks and contracts
  Danish banks, insurance companies, and telecom providers usually require a permanent CPR number and proof of address in Denmark. With a temporary CPR number, opening a bank account or signing long-term contracts can be more difficult or subject to stricter conditions.

How to know which type of CPR number you can get

The type of CPR number you receive depends on your legal basis for staying in Denmark and your actual living situation:

• If you move to Denmark to live here for at least several months and you have a valid residence basis (for example, employment contract, study, EU right of residence, family reunification), you will normally be registered with a permanent CPR number.
• If you only work in Denmark for a short period, commute from another country, or receive Danish income without moving your residence, you will usually receive a temporary CPR number for tax and administrative purposes.

What it means for you in practice

Before you come to Denmark or start working here, clarify whether you will be treated as a resident or non-resident. This will determine:

• whether you can obtain a permanent CPR number and a registered address
• your access to public healthcare and other social benefits
• whether you will be fully or partially tax liable in Denmark
• how easily you can open a bank account, sign a rental contract, and obtain MitID

If you are unsure which type of CPR number you qualify for, it is important to check your specific situation with the relevant authorities or a professional advisor. Choosing the correct registration from the start helps avoid problems with tax, social security, and access to services later on.

Required documents and typical mistakes that delay obtaining a CPR number

To obtain a Danish CPR number smoothly, it is crucial to prepare the correct documentation and avoid common mistakes that cause delays. The exact documents depend on your situation (employee, student, accompanying family member, EU/EEA or non‑EU), but the authorities always expect clear proof of your identity, legal stay and reason for residence in Denmark.

Core documents required in most cases

When you apply for a CPR number at the local Citizen Service (Borgerservice) or International Citizen Service, you will typically need:

• Valid passport or national ID card (for EU/EEA and Nordic citizens, an ID card can be enough; for non‑EU citizens, a passport is required)
• Residence permit or proof of legal stay:
  • EU/EEA citizens: EU registration certificate (residence document) if you stay longer than 3 months
  • Non‑EU citizens: valid residence permit card or approval letter from the Danish Immigration Service/SIRI
• Proof of address in Denmark (rental contract, sublease agreement, housing allocation letter or written confirmation from the main tenant/landlord)
• Documentation of your basis for residence, for example:
  • Employment contract or employer declaration for workers
  • Admission letter from a Danish educational institution for students
  • Marriage certificate, birth certificates for children, or family reunification decision for accompanying family members
• Civil status documentation (marriage certificate, divorce decree, death certificate of spouse, if relevant)
• Birth certificate for children who need a CPR number

All documents must show your full name, date of birth and, where relevant, the period and conditions of your stay in Denmark. If your name has changed (for example after marriage), bring documentation of the name change as well.

Language and form of documents

Danish authorities accept documents in Danish, English and often in German or Scandinavian languages. If your documents are in another language, you may need an official translation by an authorised translator. In some cases, especially for non‑EU documents, you may also be asked for an apostille or legalisation to confirm authenticity.

Bring both the original documents and, if possible, copies. Electronic documents (PDFs) are often accepted if they clearly show all details, but the municipality can still ask to see originals.

Specific documentation by category

Depending on your situation, additional documents are typically required:

• Employees:
  • Signed employment contract stating job title, working hours per week, salary and start date
  • Sometimes a confirmation from your employer that the job is ongoing and not purely nominal
• Self‑employed:
  • Documentation of business registration (CVR number)
  • Business plan, contracts or other proof that the activity is real and carried out in Denmark
• Students:
  • Admission letter from a Danish university, academy or vocational school
  • Confirmation of the duration of your studies and whether they are full‑time
• Accompanying family members:
  • Marriage certificate or registered partnership certificate
  • Birth certificates for children
  • Proof that the main applicant legally resides in Denmark (for example residence card, EU registration certificate, employment contract)
• Cross‑border workers:
  • Employment contract in Denmark
  • Proof of address in your home country
  • In some cases, documentation that you regularly commute

Typical mistakes that delay obtaining a CPR number

Many applications are delayed not because of complex legal issues, but due to simple, avoidable errors. The most common are:

• Incomplete address documentation – rental contracts without start date, missing signatures, or no clear indication that you actually live at the address. Subletting without written permission from the landlord can also cause problems.
• Unclear employment situation – contracts without working hours, salary or start date, or “zero‑hour” contracts that do not clearly show real employment. Authorities may doubt whether the job is genuine, which leads to additional checks.
• Missing or inconsistent civil status documents – for example, stating that you are married but not providing a marriage certificate, or using different surnames in different documents without proof of name change.
• Expired or invalid residence permit – applying with a permit that has already expired or does not allow residence in Denmark (for example, a visa for another Schengen country).
• Wrong assumptions about EU rights – EU/EEA citizens sometimes assume that a passport alone is enough for a long‑term stay. For stays over 3 months based on work, study or sufficient funds, you normally need an EU residence document before you can be registered with a CPR number.
• Documents in unsupported languages without translation – birth or marriage certificates in languages not understood by the caseworker, without an official translation, often lead to requests for additional documentation.
• Not booking an appointment or missing the appointment – in many municipalities you must book a time slot at Citizen Service. Turning up without an appointment, or arriving without all required documents, usually means you have to come back later.
• Using temporary or informal housing without proof – staying with friends or in short‑term accommodation without a written confirmation that you live there makes it difficult to register your address in the folkeregister, which is necessary for a CPR number.

How to prepare to avoid delays

Before you go to Citizen Service, check the website of your municipality or the International Citizen Service for an updated checklist of required documents for your specific situation. Make sure that:

• All names, dates of birth and addresses are consistent across documents
• Your residence permit or EU registration is valid and clearly states your right to reside in Denmark
• Your housing situation is documented with a signed contract or written confirmation
• Foreign documents are translated and, where required, legalised or apostilled

Careful preparation significantly reduces the risk of additional questions from the authorities and helps you obtain your CPR number faster, so you can move on to tax registration, opening a bank account and accessing the Danish healthcare and social systems without unnecessary delays.

Where and how to apply for a CPR number (online vs. in-person at the Citizen Service)

In Denmark, applications for a CPR number are handled by the local Citizen Service (Borgerservice) or, for many foreign employees and students, by specialised international citizen service centres such as International Citizen Service (ICS). Whether you can apply online or must appear in person depends on your residence basis, length of stay and whether you are moving your address to Denmark.

Online pre‑registration vs. in‑person application

For most people, the process is a combination of online pre‑registration and a mandatory in‑person visit:

• Online pre‑registration – many municipalities and ICS centres allow or require you to submit basic information and upload documents before your visit. This is common for EU/EEA workers, students and some accompanying family members. Pre‑registration does not give you a CPR number by itself; it only prepares your case.
• In‑person registration – in almost all cases you must appear personally at Citizen Service to complete the registration, verify your identity with original documents and confirm your Danish address. Biometric data are not taken for CPR, but staff must see you in person.

Fully online issuance of a CPR number without any physical appearance is currently very limited and typically not available to newly arrived residents. If a website or intermediary offers a “CPR number online without visit”, you should treat it with caution and verify directly with the municipality or ICS.

Where to apply: municipality, ICS and special centres

You normally apply for a CPR number in the municipality where you live or will live. The main options are:

• Local Citizen Service (Borgerservice) – this is the standard place for most residents. Each municipality has at least one Citizen Service office where you can register your address, obtain a CPR number and later update your details.
• International Citizen Service (ICS) – located in Copenhagen, Aarhus, Odense and Aalborg. ICS is designed for foreign workers, researchers, students and accompanying family members. In many cases, ICS can help you with CPR registration, tax registration and guidance on MitID in one visit.
• Special arrangements for students – some universities organise registration events together with the municipality or ICS at the beginning of the semester. You still receive your CPR number from the public authority, but the application can be submitted at the campus event.

If you are a cross‑border worker who does not move your address to Denmark, you typically register at a special unit such as Folkeregistret for grænsependlere or a designated Citizen Service office, depending on where your employer is located and current administrative practice.

How to book an appointment

Most Citizen Service and ICS offices work primarily with booked appointments to avoid long waiting times. You usually book your time slot via the municipality’s website or the ICS website. In larger cities, walk‑in options are often limited and may involve significant waiting.

When booking, you will normally be asked to choose the purpose of your visit (for example “CPR registration – moving from abroad” or “EU registration and CPR”). Selecting the correct purpose helps ensure that you are given enough time and that the right staff are available.

Step‑by‑step: typical application flow

1. Check which authority is responsible for you – confirm on the website of your municipality or ICS whether you should apply there, and whether you must obtain an EU residence document or residence permit first.
2. Prepare documents – gather your passport or national ID card, residence permit or EU registration certificate (if required), employment contract or admission letter, marriage and birth certificates for family members, and proof of address in Denmark (rental contract, housing confirmation, or employer‑provided housing).
3. Complete online pre‑registration (if available) – fill in the online form, upload scans of your documents and choose a time for your in‑person visit. Make sure names and dates are written exactly as in your passport.
4. Attend your appointment in person – bring all original documents. The officer will verify your identity, check that you meet the conditions for registration and enter your data into the Civil Registration System.
5. Confirm your address – you must provide a valid Danish address where you actually live. In many municipalities, the system may send a letter to your address or require your landlord to confirm your residence.
6. Receive your CPR number – in many cases you receive your CPR number immediately at the counter or shortly after by secure digital message or letter. Your yellow health card (sundhedskort) is then sent by post to your registered address.

Online tools and forms

Several national and municipal digital solutions support the CPR application process:

• Life in Denmark / borger.dk – central portals where you can find links to the correct forms for moving to Denmark, registering as an EU citizen and booking appointments with Citizen Service or ICS.
• Municipal self‑service forms – many municipalities offer English‑language online forms for “Registration when moving to Denmark” that allow you to enter your data before your visit.

Access to some digital services requires MitID, which you usually cannot obtain before having a CPR number. Therefore, the first registration often relies on “open” forms that do not require login, or on email/phone contact with the municipality.

Practical tips for a smooth application

To avoid delays and repeated visits:

• Always bring original documents, not only copies or scans.
• Ensure your name, date of birth and family relations are consistent across all documents. Differences in spelling or missing apostrophes and middle names can cause problems later with banks, employers and tax.
• Check in advance whether your marriage and birth certificates must be legalised or translated into English or Danish.
• Make sure your rental contract or housing confirmation clearly states your name, the full address and the start date of your tenancy.
• Arrive on time for your appointment and keep confirmation emails or SMS messages in case you need to show them at the reception.

Choosing the correct place to apply and preparing thoroughly before your visit will significantly speed up obtaining your CPR number and allow you to move on quickly to the next steps such as opening a bank account, registering for tax and getting access to digital self‑service in Denmark.

CPR number and registration of address (folkeregister) – why they are linked

The Danish CPR number and your registered address in the folkeregister are closely connected. In practice, you cannot fully “activate” your CPR number without registering where you live. For most people moving to Denmark, getting a CPR number, registering an address and gaining access to healthcare, salary payments and digital self‑service all happen in one combined process.

The folkeregister is the official Danish Civil Registration of where people live. It is maintained by the municipalities and linked directly to the CPR system. When you register your address, the municipality updates your data in the CPR register. Public authorities, banks and employers then use this information as the legal source of truth about your residence in Denmark.

Why you usually need a fixed address to get a CPR number

As a rule, you must have a place to live in Denmark and intend to stay for more than 3 months (6 months for some cross‑border situations) to obtain a standard, permanent CPR number. The address you register must be an actual residence where you can receive mail, such as a rented apartment, a room in a shared flat, a student dormitory or a company‑provided accommodation. Hotels, hostels or short‑term holiday rentals are normally not accepted as a long‑term address for folkeregister purposes.

When you apply for a CPR number at the local Citizen Service (Borgerservice) or International Citizen Service, you are usually asked to present documentation of your housing, for example a signed rental contract, a housing allocation letter from a dormitory or a written agreement with your landlord. Without this, the municipality can refuse to register your address and, in many cases, will not issue a CPR number.

What happens when your address is registered

Once your address is registered in the folkeregister and your CPR number is activated, several important things happen automatically:

• You are assigned to a municipality of residence, which determines which local services you can use
• You are normally enrolled in the public health system and can choose or are allocated a general practitioner (GP)
• Your tax municipality is set, and the Tax Agency (SKAT) can link your income and tax card to your CPR number and address
• Public authorities know where to send official letters, including digital post notifications linked to your MitID
• Banks, insurance companies and employers can verify your identity and address against the official register

Because so many systems rely on the folkeregister, having a correct and updated address is essential for receiving salary, tax information, health insurance cards (yellow card), child benefits and other public payments.

Temporary CPR numbers and address registration

Some people receive a temporary CPR number (often called a tax number or skattenummer) when they work in Denmark for a short period or as cross‑border workers. In these cases, you may not be required to register an address in Denmark if you are officially resident in another country and commute or stay only briefly. However, if your situation changes and you start living in Denmark on a more permanent basis, you will normally have to register your Danish address and your temporary number may be converted into a permanent CPR number.

Obligation to report changes of address

If you already have a CPR number and move to a new address in Denmark, you are legally required to report your new address to the folkeregister within a short deadline, typically no later than 5 days after moving. You can usually do this online using your MitID or by visiting Citizen Service in person. Failing to update your address can lead to practical problems, such as missing important letters from SKAT or your municipality, and in some cases may result in administrative fines.

When you move to another municipality, your new municipality becomes responsible for your registration, local services and health coverage. Your GP may change, and you may receive a new health insurance card showing your updated address and doctor.

Leaving Denmark and deregistration

If you leave Denmark for more than 6 months and no longer have your main residence in the country, you must deregister from the folkeregister. Your CPR number remains in the system but is marked as no longer resident. This information is important for tax purposes and for determining your access to Danish public services. If you later return to Denmark, you will usually keep the same CPR number, but you must register a new address and reactivate your status in the folkeregister.

Because the CPR system and the folkeregister are so tightly linked, planning your housing and address registration early is one of the most important steps when relocating to Denmark. Correct address registration ensures that your CPR number works as intended and that you can access the full range of rights and services connected to living and working in Denmark.

How long does it take to get a CPR number and how to track your application

Processing time for a CPR number in Denmark depends mainly on your basis for residence (work, study, family reunification, cross‑border work) and how complete your application is. In most straightforward cases, you can expect to receive your CPR number within 1–3 weeks from the date your application is accepted and all required documents have been submitted. In more complex cases, for example when immigration grounds must be assessed in detail, the process can take longer.

For EU/EEA citizens who have already obtained an EU registration certificate and registered their address with the municipality, the CPR number is usually issued relatively quickly after the in‑person visit at the Citizen Service (Borgerservice). Non‑EU citizens normally receive their CPR number only after their residence permit has been approved by the Danish Agency for International Recruitment and Integration (SIRI) and they have completed address registration. If your residence permit is still being processed, the municipality cannot issue a CPR number.

In many municipalities, you will first receive your CPR number by digital letter in your e‑Boks or MitID inbox, and later by physical letter to your registered address. The physical yellow health card (sundhedskort) is typically sent a few days after the CPR number has been created, but it can take up to a couple of weeks to arrive by post. You can usually start using your CPR number for tax, salary and banking as soon as you know the number, even if the plastic card has not yet arrived.

To track the status of your CPR application, start with the authority that is currently handling your case. If your residence permit is still under review, you should follow the status via SIRI’s or the Danish Immigration Service’s online self‑service or by contacting them directly. Once your residence permit has been granted and you have booked and attended your appointment at the Citizen Service, further questions about the CPR number itself should be directed to the municipality where you registered your address.

Most municipalities provide information about expected processing times on their websites and offer contact forms, phone lines or in some cases secure digital mail for status enquiries. When you contact them, always provide your full name, date of birth, any case or file number you have received, and the date of your appointment or online application. This helps them locate your case faster and give you a more precise answer.

If you have MitID and access to e‑Boks, you can often see when a CPR number has been created because you will receive a digital letter from the municipality or the Danish Health Data Authority. In addition, your employer or bank may be able to see in their systems that your CPR number has become active, even before you receive the physical health card. However, they cannot speed up the public processing; only the relevant authority can do that.

Delays most often occur when documents are missing, your address registration is incomplete, or there is a mismatch between the information held by different authorities (for example, name spelling, passport number or residence permit details). To avoid this, make sure that all documents are up to date, consistent and translated if required, and that you attend your appointment with the municipality on time with all originals. If processing takes significantly longer than the typical timeframe indicated by the municipality, it is advisable to contact them and, if relevant, SIRI or the Immigration Service to check whether they are waiting for additional information from you.

From a practical and tax perspective, it is important to obtain your CPR number as early as possible after arriving in Denmark. Without it, your employer cannot correctly register your income with the Danish Tax Agency (Skattestyrelsen), and you risk being taxed at the high default rate until your CPR number and tax card are in place. If you are unsure whether the waiting time in your situation is normal, a Danish accounting or tax advisor can help you interpret the information from the authorities and plan your salary, tax and social security arrangements while you are waiting for your CPR number.

Using your CPR number in everyday life: banking, salary, doctor, NemID/MitID

Your CPR number is the key to almost every formal aspect of life in Denmark. Without it, opening a bank account, receiving salary, visiting a doctor or using digital solutions such as MitID is either impossible or very complicated. Below you will find the most important ways in which you will use your CPR number every day.

Bank account and payments

To open a standard Danish bank account, including a NemKonto (mandatory account for receiving salary and public payments), you must provide your CPR number. Banks use it to verify your identity in national registers and to report information to the tax authorities (SKAT).

When opening an account, the bank will usually ask for:

• your CPR number and valid ID (passport or national ID card)
• residence document (e.g. EU registration certificate or residence permit)
• proof of address in Denmark
• employment contract or other documentation of income

Once your account is active, your CPR number is linked to your NemKonto. This is where you receive salary, holiday pay, tax refunds, child benefits and other public payments. Without a CPR number, you cannot set up a NemKonto, which in practice makes normal functioning in Denmark very difficult.

Salary, employment and pension

Employers in Denmark are required to use your CPR number to report salary, tax and social contributions to SKAT and other authorities. Your CPR number appears on:

• your employment contract and payroll system
• monthly payslips
• annual tax statement (årsopgørelse) and income overview (eIndkomst)

Based on your CPR number, your employer withholds:

• labour market contribution (AM-bidrag) at 8% of your gross salary
• income tax according to your tax card (skattekort), which is also linked to your CPR number

Your CPR number is also used to register contributions to Danish pension schemes (ATP and any occupational pension). When you change jobs, the new employer can correctly continue contributions because all information is connected to your CPR number, not to a specific company.

Doctor, health care and health card (sundhedskort)

After registering your address and obtaining a CPR number, you are assigned a general practitioner (GP) and receive a yellow health card (sundhedskort). The card shows your CPR number and is your proof of entitlement to public health care in Denmark.

You will need your CPR number when you:

• register with a GP or change doctor
• book medical appointments, including online bookings
• visit a hospital, emergency room or specialist
• use the e-Boks and sundhed.dk portals to view test results and prescriptions

At clinics and hospitals, staff usually scan your health card. If you do not have the card with you, they will ask for your CPR number to find your medical records. Pharmacies also use your CPR number to access electronic prescriptions and register purchases of prescription medicines.

NemID/MitID and access to public digital services

MitID (which has replaced NemID) is Denmark’s digital ID. It allows you to log in securely to public and private online services. To obtain MitID, you must have a CPR number, as it is used to verify your identity against the national register.

With your CPR number and MitID you can, among other things:

• log in to skat.dk to view and change your tax information
• access e-Boks, where you receive official letters from authorities, banks and insurance companies
• manage your NemKonto and bank accounts online
• use borger.dk to apply for benefits, register address changes or request certificates
• log in to sundhed.dk to see your health data, prescriptions and vaccination history

Most public institutions and many private companies in Denmark assume that you have MitID linked to your CPR number. Without it, many procedures become slower and require in-person visits.

Other everyday situations where you will need your CPR number

Your CPR number will also be used in many other contexts, for example when you:

• sign a rental contract and register your address with the municipality
• take out insurance (home, liability, car, health)
• register a car and obtain licence plates
• enrol children in daycare or school
• sign up for language courses or other education
• enter into instalment agreements or mobile phone contracts

In all these situations, the CPR number allows institutions and companies to identify you, check your data in public registers and report information to the relevant authorities.

Because your CPR number is so widely used, it is important to memorise it and use it carefully. Share it only when it is necessary and with trusted institutions. At the same time, make sure that your CPR number is correctly registered with your employer, bank and municipality, as any errors can affect your salary, tax, access to health care and other key aspects of life in Denmark.

CPR number and tax registration (SKAT) – what happens automatically and what does not

When you receive a Danish CPR number, you are automatically registered in several public systems, including the tax system. However, this does not mean that all tax matters are handled for you. Understanding what SKAT (now part of the Danish Tax Agency – Skattestyrelsen) does automatically and what you must do yourself is crucial to avoid unexpected tax bills or penalties.

What happens automatically after you get a CPR number

Once your CPR number is created and your address is registered in the Danish Civil Registration System, basic information is shared with the Danish Tax Agency. On this basis, the following usually happens automatically:

• Creation of your tax account (skattekonto) and tax file
• Assignment of a preliminary tax assessment (forskudsopgørelse) once you have income or certain benefits reported
• Automatic reporting of salary and many benefits by employers and public authorities via the eIncome system (eIndkomst)
• Automatic calculation and withholding of income tax and labour market contribution (AM-bidrag) by your employer, provided they have your correct tax card

Employers in Denmark are obliged to report your salary, pension contributions and certain benefits every month. These reports are linked to your CPR number and are used by SKAT to calculate whether you have paid the right amount of tax.

Tax card and preliminary tax assessment – what you must check

Having a CPR number does not guarantee that your tax card (skattekort) is correct. Your tax card is based on your preliminary tax assessment, which you must review and update yourself. This is especially important if you:

• Start your first job in Denmark
• Have more than one employer
• Receive both salary and Danish social benefits or pension
• Move to or leave Denmark during the year

In Denmark, income tax is calculated using a combination of municipal tax, state tax and labour market contribution. The labour market contribution is 8% of your gross salary before other taxes. On top of that, you pay:

• Municipal and church tax, which together typically range around 24–27% depending on the municipality and whether you pay church tax
• Bottom-bracket state tax of 12.10% on personal income above the personal allowance
• Top-bracket state tax of 15% on the part of your personal income that exceeds the top tax threshold (around DKK 588,900 per year before AM-bidrag)

Everyone who is fully tax liable in Denmark receives a personal allowance (personfradrag). For adults, this allowance is around DKK 49,700 per year. You do not pay bottom-bracket state tax or municipal tax on income below this allowance, but you still pay the 8% labour market contribution on salary.

Types of tax cards: main, secondary and B-income

Your CPR number allows SKAT to issue different types of tax cards, but you must ensure that each employer uses the correct one:

• Main tax card (hovedkort) – used by your primary employer. It includes your personal allowance and is where most of your income should be taxed.
• Secondary tax card (bikort) – used by any additional employers. Income on this card is taxed without using the personal allowance, usually at a higher rate.
• B-income card (B‑skat) – used for income where no employer withholds tax, such as freelance work or certain fees. You must pay this tax yourself, typically in instalments.

If two employers both use your main tax card, your personal allowance will be used twice and you will almost certainly receive a tax bill (restskat) after the year ends. You must log into the SKAT system (TastSelv) with your CPR number and MitID to assign the correct card to each employer.

What does not happen automatically – your responsibilities

Even though your CPR number connects you to the tax system, several important actions are not automatic and are your responsibility:

• Registering that you have moved to Denmark and become tax resident, if this is not already clear from your CPR registration and employment
• Entering expected annual income, deductions and allowances in your preliminary tax assessment
• Updating your information when your salary changes significantly, you change jobs, or you start/stop receiving benefits
• Declaring foreign income, foreign bank accounts and assets if you are fully tax liable in Denmark
• Checking and correcting your annual tax statement (årsopgørelse) after the end of the tax year

Common deductions that do not always appear automatically include transport deduction (befordringsfradrag) for commuting over 24 km per day, union fees and unemployment fund contributions (up to the current deductible limits), and interest paid on certain loans. You must enter these in TastSelv yourself.

CPR number, tax residence and limited vs. full tax liability

Having a CPR number does not always mean you are fully tax resident in Denmark, but in practice, registration with a Danish address and a stay of more than six months usually leads to full tax liability. In that case, Denmark can tax your worldwide income, subject to double tax treaties.

If you are a cross-border worker or stay in Denmark for a shorter period, you may be subject to limited tax liability only on Danish-source income. The CPR number is still used to identify you in the tax system, but the rules for what income is taxed and which deductions you can claim are different. It is important to inform SKAT about your situation so that your preliminary tax assessment reflects the correct type of tax liability.

Deadlines, back taxes and refunds

Your CPR number is used to match all reported income and deductions and to calculate whether you have paid too much or too little tax. After the end of the tax year, SKAT issues your annual tax statement. If you have paid too much, you receive a refund to your Danish bank account (NemKonto). If you have paid too little, you must pay back taxes, often with interest or a surcharge if the amount is not paid within the deadlines.

Typical reasons for back taxes include:

• Not updating your preliminary tax assessment after a salary increase
• Two employers using your main tax card
• Not declaring foreign income while being fully tax liable in Denmark
• Incorrect or missing information about deductions

Regularly checking your tax information in TastSelv using your CPR number and MitID helps you avoid unpleasant surprises and ensures that your tax withholding matches your actual situation.

How an accounting firm can help

The combination of CPR registration and Danish tax rules can be complex, especially for newcomers, cross-border workers and people with income from several countries. A professional accounting firm can:

• Set up and review your preliminary tax assessment after you obtain your CPR number
• Ensure that your tax cards are correctly allocated between employers
• Identify and claim all relevant deductions and allowances
• Advise on tax residence status and double taxation agreements
• Assist with annual tax returns and communication with SKAT

Using your CPR number correctly in the tax system from the very beginning helps you avoid back taxes, penalties and unnecessary stress, and ensures that you pay exactly the tax you are required to pay – no more and no less.

CPR number for EU/EEA citizens vs. non‑EU citizens – key differences

Whether you are an EU/EEA or a non‑EU citizen has a direct impact on how you obtain a CPR number in Denmark, how long you can stay, and which documents you must present. Understanding these differences will help you prepare the right paperwork and avoid delays.

Legal basis: free movement vs. residence permit

EU/EEA citizens benefit from the EU rules on free movement. This means you generally have the right to live and work in Denmark if you meet certain conditions, for example by being employed, self‑employed, a student or financially self‑sufficient. Non‑EU citizens do not have this automatic right and usually need a residence and work permit granted before they can obtain a CPR number.

In practice, this means:

• EU/EEA citizens usually apply first for an EU registration certificate and then for a CPR number.
• Non‑EU citizens usually receive a residence permit from the Danish Agency for International Recruitment and Integration (SIRI) or the Danish Immigration Service and then use this permit to register for a CPR number.

Minimum stay and typical scenarios

In both cases, a CPR number is normally issued if you are staying in Denmark for more than 3 months (or more than 6 months if you are a cross‑border worker who lives in another country). However, the way you document your right to stay is different:

• EU/EEA citizens staying more than 3 months must obtain an EU registration certificate and register their address to get a CPR number.
• Non‑EU citizens must have a valid residence permit that clearly allows residence in Denmark for more than 3 months.

Key steps for EU/EEA citizens

If you are an EU/EEA citizen, the process is usually shorter and more flexible. You typically need to:

• Document your identity with a valid passport or national ID card.
• Prove the basis for your stay:
  • Employees: employment contract or firm job offer stating working hours and salary.
  • Self‑employed: documentation of business activity, for example registration with the Danish Business Authority (CVR) and contracts or invoices.
  • Students: admission letter from a recognised Danish educational institution.
  • Self‑sufficient persons: proof of sufficient funds and comprehensive health insurance covering you in Denmark.
• Apply for an EU registration certificate (often at SIRI or an International Citizen Service centre).
• Register your address at the local Citizen Service (Borgerservice) to obtain your CPR number.

For many EU/EEA citizens, the EU registration certificate and CPR registration can be handled in one visit at an International Citizen Service, especially in larger cities.

Key steps for non‑EU citizens

Non‑EU citizens face stricter entry and residence rules. Before you can apply for a CPR number, you usually need to:

• Obtain a residence permit that allows you to live in Denmark (for example as a worker, researcher, student, accompanying family member or under a specific scheme such as the Pay Limit Scheme).
• Enter Denmark with the correct visa if required (for example a long‑term visa or a visa linked to your residence permit).
• Register your address at the local Citizen Service once you have moved into your Danish residence.

When you register for a CPR number, you must present your residence permit (physical card or approval letter), passport and documentation of your Danish address, such as a rental contract or housing confirmation.

Employment and work permit differences

For EU/EEA citizens, the right to work in Denmark follows from the right of free movement. Once you have an EU registration certificate and a CPR number, you can work for any employer or be self‑employed, as long as you continue to meet the conditions (for example actually working or actively running your business).

Non‑EU citizens are usually tied to a specific permit type and often to a specific job or employer. For example, under the Pay Limit Scheme, your residence and work permit is linked to a particular position with a minimum annual salary threshold set by Danish law. Changing employer or job type can require a new permit. Without a valid work permit, you cannot legally work in Denmark even if you have a CPR number.

Access to healthcare and social benefits

Once you are registered with a CPR number and address, both EU/EEA and non‑EU residents normally gain access to the Danish public healthcare system and receive a yellow health insurance card. However, the path to this point differs:

• EU/EEA citizens must first prove a legal basis for residence under EU rules. In some cases, you may need to show an EU health insurance card (EHIC) or private insurance until you are fully registered.
• Non‑EU citizens must have a residence permit that includes the right to stay in Denmark. Some short‑term or limited permits may not give full access to public healthcare, and you may need private insurance during the initial period.

Eligibility for social benefits (such as certain family benefits or unemployment benefits) is not the same as eligibility for a CPR number. Both EU/EEA and non‑EU citizens must meet additional conditions, such as residence requirements, work history and membership of an unemployment insurance fund (a‑kasse). Simply having a CPR number does not automatically grant access to all benefits.

Family members and reunification

The rules for family members also differ significantly:

• Family of EU/EEA citizens can often obtain residence rights in Denmark as accompanying family members under EU law, even if they are non‑EU nationals. They must document the family relationship (for example marriage certificate or birth certificate) and the EU citizen’s legal residence in Denmark.
• Family of non‑EU citizens usually need a separate family reunification permit under Danish national rules, which can be more restrictive and involve specific income, housing and integration requirements.

In both cases, once the family member’s residence right or permit is approved and the person is registered at a Danish address, they can apply for a CPR number.

Processing times and practical impact

In practice, EU/EEA citizens often experience faster processing when applying for an EU registration certificate and then a CPR number, especially if all documents are in order. Non‑EU citizens may wait longer because their residence permits involve more detailed checks and, in some cases, security assessments.

The difference matters for everyday life: without a CPR number you cannot easily receive salary in a Danish bank account, register for tax, choose a doctor, obtain MitID or sign many contracts. For non‑EU citizens, delays in the residence permit stage automatically delay the CPR number. For EU/EEA citizens, missing or incomplete documentation of work, study or financial self‑sufficiency is the most common reason for slower processing.

Summary: what it means for you

If you are an EU/EEA citizen, the CPR process is built around your right to free movement and an EU registration certificate. If you are a non‑EU citizen, everything starts with obtaining the correct residence and work permit. In both cases, you need a documented basis for staying more than 3 months and a registered Danish address. Preparing the right documents in advance and understanding which rules apply to your nationality will make obtaining your CPR number in Denmark significantly smoother.

CPR number for cross‑border workers and short‑term employees

Many people work in Denmark without moving here permanently. If you are a cross‑border worker or a short‑term employee, whether you need a CPR number depends mainly on the length and nature of your stay, your employment contract and where you are tax resident.

In Danish practice, a cross‑border worker is typically someone who lives in another country (for example Germany, Sweden or Poland), but works regularly in Denmark and returns home at least once a week. A short‑term employee is usually someone who comes to Denmark for a limited project or seasonal work, often for a few weeks or months.

Do cross‑border workers need a CPR number?

If you live outside Denmark and commute to work here, you normally do not obtain a permanent CPR number, because you are not considered resident in Denmark. Instead, you are usually registered with the Danish Tax Agency (SKAT) using your foreign address and an identification number created for tax purposes. However, in some situations a CPR number is still required or strongly recommended:

• you work in Denmark for at least 3 consecutive months and stay here several days per week
• you rent accommodation in Denmark and are considered to have a place of residence here
• you need access to the public health system as an insured person in Denmark
• you need NemID/MitID and full access to Danish digital self‑service solutions

If you are not registered as living in Denmark, you will normally not receive a yellow health card and will not be fully covered by the Danish public health system. In that case, you should rely on health insurance from your home country (for example the European Health Insurance Card for EU/EEA residents) or private insurance.

CPR number for short‑term employees (less than 3 months)

If you come to Denmark to work for less than 3 months and you do not move your residence here, you are usually not registered in the Danish Civil Registration System as a resident and you do not receive a permanent CPR number. You can still be taxed in Denmark on your Danish salary, but this is handled through a tax number and your foreign address.

In practice, many short‑term employees work under the so‑called “limited tax liability” in Denmark. The employer reports your income to SKAT using your foreign identification details, and you are taxed according to Danish rules for non‑residents. You may need to apply for a tax card or a special tax scheme, but this is separate from the CPR registration.

When a CPR number is required despite a short stay

Even if you plan to work only for a short period, you may still need a CPR number if:

• you stay in Denmark for at least 3 months (or 6 months if you are a Nordic citizen) and register an address in the folkeregister
• you bring your spouse or children and they will live with you in Denmark
• you need a Danish bank account to receive your salary and your bank requires a CPR number
• you need access to a Danish general practitioner (family doctor) and other public services

In these cases, you must register your address with the local Citizen Service (Borgerservice) and apply for a CPR number as a resident. For EU/EEA citizens this usually requires a registration certificate from SIRI, while non‑EU citizens normally need a valid residence and work permit before they can be registered.

Tax registration vs. CPR number for cross‑border and short‑term workers

It is important to distinguish between tax registration and CPR registration. You can be fully liable to pay tax in Denmark on your Danish salary without having a CPR number. As a cross‑border or short‑term worker you typically need to:

• obtain a Danish tax card or a preliminary income assessment from SKAT
• ensure your employer has your correct foreign address and identification details
• check whether you fall under limited or full tax liability in Denmark, depending on the length of your stay and your ties to Denmark

Only when you meet the conditions for residence registration (for example, staying in Denmark for at least 3 months with a fixed address) does the CPR number become mandatory. Before that, your tax affairs can be handled with a tax number and your foreign address.

Practical consequences of not having a CPR number

If you work in Denmark as a cross‑border or short‑term employee without a CPR number, you should be aware of some limitations:

• you may have restricted access to public healthcare in Denmark and may need to rely on insurance from your home country
• some banks, mobile operators and digital platforms may refuse to open accounts or contracts without a CPR number
• you may not be able to obtain NemID/MitID or a Danish digital mailbox, which makes some public procedures more complicated

On the other hand, you also avoid some obligations linked to residence in Denmark, such as full social security coverage and certain reporting duties. Whether you should apply for a CPR number therefore depends on your concrete situation, the expected duration of your work in Denmark and your long‑term plans.

If you are unsure whether you qualify for a CPR number as a cross‑border worker or short‑term employee, it is advisable to clarify your status with the local Citizen Service and with SKAT before you start working. Proper registration from the beginning helps avoid problems with salary payments, taxation and access to services later on.

CPR number for accompanying family members and children

When you move to Denmark with your spouse, partner or children, each accompanying family member usually needs their own CPR number. Without it, they cannot access the public healthcare system, receive salary, open a bank account, enroll in school or daycare, or use digital self‑service solutions such as MitID and e‑Boks.

Who can obtain a CPR number as an accompanying family member

Accompanying family members can normally obtain a CPR number if they have a legal basis to stay in Denmark for more than 3 months (for EU/EEA citizens) or more than 3 months on a residence permit (for non‑EU citizens), and they register an address in the Danish Civil Registration System (folkeregister).

Typical categories include:

• Spouse or registered partner of a person working, studying or otherwise legally residing in Denmark
• Cohabiting partner (in some cases, depending on the residence basis and documentation of the relationship)
• Children under 18 years of age (biological, adopted or, in some cases, stepchildren) who live with the parent in Denmark
• Other close family members (for example parents of an adult sponsor) – only in specific, more limited situations and usually with stricter requirements

EU/EEA accompanying family members

If the main applicant is an EU/EEA citizen using free movement rights (for example as a worker, self‑employed person or student), accompanying family members who are EU/EEA citizens usually need:

• A valid passport or national ID card
• Proof of family relationship (marriage certificate, birth certificate, documentation of partnership)
• Proof that they will live in Denmark (rental contract, housing confirmation, or a written statement from the person they will live with)

Before applying for a CPR number, many municipalities require EU/EEA citizens to obtain an EU registration certificate from the Danish Agency for International Recruitment and Integration (SIRI). Once the EU registration certificate is issued and the address is registered at the Citizen Service (Borgerservice), the CPR number is created.

Non‑EU accompanying family members

Non‑EU family members usually need a valid residence permit as an accompanying family member before they can obtain a CPR number. The permit is typically issued by SIRI or the Danish Immigration Service based on family reunification or as an accompanying family member to a worker, researcher, student or other main permit holder.

For these family members, the typical sequence is:

1. Apply for a residence permit as an accompanying family member
2. Receive the residence permit approval
3. Enter Denmark and register your address at the Citizen Service
4. Obtain a CPR number and a yellow health insurance card

CPR numbers for children

Children who move to Denmark with their parents generally receive a CPR number when they are registered in the Civil Registration System at the same address as the parent. For newborn children in Denmark, the CPR number is created automatically when the birth is registered, usually by the hospital or the midwife.

For children arriving from abroad, you will normally need:

• The child’s passport
• Birth certificate (with official translation if not in English, Danish, Norwegian or Swedish)
• Documentation of custody if parents are separated or divorced
• Residence permit or EU registration basis, depending on nationality
• Proof of address in Denmark

Once the child has a CPR number, you can register them with a general practitioner (GP), apply for daycare (vuggestue, børnehave) or school, and access child‑related benefits if you meet the conditions.

Practical steps for families applying together

In many municipalities, the most efficient approach is for the main applicant to obtain their residence basis and CPR number first, and then register accompanying family members. However, some Citizen Service offices allow joint registration appointments for the whole family. It is important to:

• Book an appointment in advance with the relevant Citizen Service
• Bring original documents and, if required, certified translations
• Ensure that names and dates of birth are consistent across all documents

Processing times for CPR registration at the municipality level are usually short once all documents are in order, but delays are common if family relationships or custody rights are not clearly documented.

Rights and access linked to the CPR number

For accompanying family members and children, the CPR number is the key to:

• Public healthcare and the yellow health insurance card
• MitID and access to e‑Boks and public digital services
• Tax registration and correct withholding of income tax
• Enrollment in daycare, school and after‑school care (SFO, fritidsordning)
• Social benefits and family benefits, if the legal conditions are met

The exact rights depend on the residence basis of the main applicant and the family member (for example worker, student, researcher, family reunification). Having a CPR number does not automatically guarantee entitlement to all benefits, but it is always a necessary starting point.

Common issues and how to avoid them

Typical problems for accompanying family members and children include:

• Missing or incomplete documentation of marriage, partnership or parenthood
• Different spelling of names or different dates of birth across passports and certificates
• Lack of proof of legal custody for children when parents live apart
• No valid residence permit for non‑EU family members at the time of registration

Before your appointment, check that all documents are consistent, up to date and, where necessary, legalized or apostilled and translated. This significantly reduces the risk of delays in obtaining CPR numbers for your family.

What to do if your CPR number application is rejected

If your CPR number application is rejected, it does not automatically mean you have no right to be registered in Denmark. It usually means that the authorities are missing documentation, have doubts about your legal basis for residence, or believe that your stay does not meet the conditions for registration. The key is to understand the reason for the refusal and react quickly and in a structured way.

1. Carefully read the rejection letter

The rejection decision (from the municipality’s Citizen Service or from SIRI/Immigration authorities, depending on your case) will normally state:

• the legal basis for the decision (for example, rules on residence for EU/EEA citizens or third‑country nationals)
• the specific reason for rejection (for example, missing employment contract, insufficient working hours, no valid residence permit, no documented address)
• whether you can appeal and within which deadline

Before taking any further steps, make sure you fully understand what exactly was considered insufficient or incorrect.

2. Check the most common reasons for rejection

In practice, CPR applications are often rejected because of:

• No documented right of residence – for example, an EU citizen without proof of work, self‑employment, studies or sufficient funds, or a non‑EU citizen without a valid residence permit from SIRI
• Too short or uncertain stay – if the authorities assess that your stay is clearly under 3 months (for EU/EEA citizens) or that your employment is very short‑term without meeting the conditions for registration
• Missing or incorrect address registration – no signed rental contract, sublease not approved by the landlord, or address that is already over‑occupied according to municipal rules
• Insufficient employment documentation – no signed contract, unclear working hours, or a contract that does not match information reported to SKAT (eIndkomst)
• Inconsistent personal data – different spelling of your name, different date of birth or passport number on various documents

Identifying which of these applies to you helps you prepare the right documents for a new application or an appeal.

3. Collect missing documents and correct errors

If the rejection is based on missing or incomplete documentation, you can often solve the problem by submitting the correct papers. Depending on your situation, this may include:

• an updated and signed employment contract stating start date, weekly working hours and salary
• confirmation from your employer that you have actually started working
• a valid residence certificate for EU/EEA citizens (EU‑registration) or a valid residence and work permit for non‑EU citizens
• a rental contract or housing confirmation covering at least 1–3 months, signed by the landlord or main tenant, including your name and the full address
• marriage certificate, birth certificates for children, or other family documents if you apply as an accompanying family member
• corrected copies of your passport or ID if there were mistakes in the initial application

Make sure that all documents are consistent: the same spelling of your name, the same address and the same start date of employment across all papers.

4. Contact the Citizen Service (Borgerservice) for clarification

If the rejection came from the municipality, you can usually ask for a meeting or call the Citizen Service to:

• clarify which specific documents are missing
• ask whether you should submit a new application or send supplementary documentation to the existing case
• verify whether your housing situation or employment meets the current rules for registration

Bring or send copies of all relevant documents so that the caseworker can give you concrete guidance. Written confirmation of what is required is always helpful if you need to reapply.

5. Understand your right to appeal and deadlines

Many decisions can be appealed, but only within a fixed time limit. The rejection letter will normally indicate:

• which authority you should appeal to (for example, the municipality, the Danish Agency for International Recruitment and Integration – SIRI, or a complaints board)
• how many weeks you have to submit your appeal
• whether the appeal must be in writing and in which language

In an appeal, you should:

1. refer to the rejection decision (case number, date, authority)
2. explain why you believe the decision is incorrect or incomplete
3. attach all new or missing documents that support your right to be registered

Appeals are usually assessed on the basis of both the original information and any new documentation you provide.

6. Reapply when your situation changes

If the rejection is correct under the rules at the time (for example, you did not yet have a valid residence permit or your employment did not meet the conditions), you can often submit a new CPR application once your situation changes. Typical examples:

• you receive a residence and work permit from SIRI
• you sign a new employment contract with sufficient working hours and duration
• you move to a stable, documented address in Denmark
• you obtain an EU registration certificate as a worker, student or self‑employed person

When reapplying, clearly state that your circumstances are now different and attach all relevant new documents from the start to avoid further delays.

7. Impact on work, salary and tax while waiting

Not having a CPR number can affect your everyday life and your tax situation, but it does not always mean you cannot work. In many cases:

• you can still work if you have the required residence and work permit or right of residence
• your employer can pay your salary, but may have to withhold tax at a higher preliminary rate until you are properly registered with SKAT
• you may have limited access to public healthcare, NemKonto, MitID and other services that require a CPR number

It is important to coordinate with your employer and, if necessary, SKAT, so that your income and tax are correctly reported from the beginning. Once you obtain a CPR number, your tax information can be linked to it and adjusted if needed.

8. Seek professional assistance if needed

CPR registration is closely connected with tax, social security and immigration rules. If your case is complex or you have already received more than one rejection, it may be worth getting professional help. A specialist familiar with Danish rules can:

• review the rejection and identify the exact legal issue
• help you prepare a complete and consistent set of documents
• coordinate your CPR registration with tax registration and, if relevant, social security coverage

Well‑prepared documentation and a clear explanation of your situation significantly increase the chances that your next application or appeal will be approved.

How to change your data linked to the CPR number (address, marital status, name)

During your stay in Denmark, some of your personal details will almost certainly change. Your CPR record must always reflect your current situation, because it is used by the tax authorities (SKAT), your employer, banks, health services and many other public and private institutions. Keeping your CPR data up to date is both a legal obligation and a practical necessity.

Which data can and must be updated

The most common changes that need to be reported are:

• change of address in Denmark or moving abroad
• change of marital status (marriage, registered partnership, divorce, separation, widowhood)
• change of name or spelling of your name
• change of citizenship or dual citizenship
• change of children’s custody or parental information

Some data can be updated online, while others require personal attendance and original documents. In all cases the change is registered in the Central Person Register and becomes visible to authorities and many service providers that rely on CPR data.

Changing your address (folkeregister)

If you move within Denmark, you must report your new address to the municipality (kommune) where you are moving. This is done through the National Registration Office (folkeregister) and is directly linked to your CPR number.

Key rules for address changes:

• You must report your move no later than 5 days after you have actually moved in.
• In most cases you can do it online via borger.dk using MitID.
• If you do not have MitID yet, you usually have to appear in person at the Citizen Service (Borgerservice).
• All persons moving to the new address (including children) must be reported in the same move notification.

When your new address is registered, it is automatically shared with SKAT, your doctor (GP), many public authorities and, in practice, with a large part of the private sector that uses CPR-based address lookups. This ensures that you receive letters, tax information and health-related correspondence at the correct address.

Moving abroad and deregistration

If you leave Denmark for more than 6 consecutive months, you are normally required to deregister from the Danish population register. You must notify your municipality before you leave or at the latest when you move. Your CPR number remains in the system, but your status changes to “emigrated”, and your Danish address is removed.

Deregistration affects your tax situation, access to the public health system and other rights, so it should be done correctly and in time. In some cases (for example, cross-border workers) special rules may apply, and it can be useful to consult an advisor before deregistering.

Changing marital status

Your marital status in the CPR system determines, among other things, how certain tax deductions are calculated and how your situation is assessed for social benefits. It is therefore important that it is always up to date.

Typical situations include:

• Marriage or registered partnership in Denmark – if the marriage is concluded in Denmark, the authorities usually update your CPR data automatically based on the marriage registration.
• Marriage abroad – you must present official documentation (marriage certificate) to your municipality. The document must normally be in Danish, English or German, or accompanied by an authorised translation. In some cases an apostille or legalisation is required.
• Divorce or legal separation – divorces granted in Denmark are reported automatically; foreign divorces may require documentation and approval before they are registered.
• Widowhood – the death of a spouse registered in Denmark is automatically reflected in your CPR record. If the spouse died abroad, you may need to provide a death certificate.

Always check that your marital status is correctly updated, especially if you are entitled to spouse-related tax deductions or benefits.

Changing your name

Name changes in Denmark are regulated by the Danish Name Act and are registered in the CPR. A change of name can affect your passport, residence documents, bank accounts and employment contracts, so it should be planned carefully.

In most cases, you apply for a name change through the national self-service solution on borger.dk or via your local parish office (if you are a member of the Evangelical Lutheran Church) or directly at the municipality. For many types of name changes, a fee applies and must be paid before the application is processed.

Typical situations include:

• taking a spouse’s surname or adding it as a middle name after marriage
• reverting to a previous surname after divorce
• correcting spelling or adapting special characters to Danish standards
• changing given names or surnames for personal reasons, subject to legal restrictions

Foreign citizens often need to present a passport, residence permit and sometimes documentation from their home country confirming that the change is accepted there. Once the name change is approved, your CPR record is updated and you must then update your documents (passport, residence card, driving licence, bank records and employment contracts) to match the new name.

How to submit changes in practice

The exact procedure depends on the type of change and your access to digital services:

• Online via borger.dk – possible for most address changes and many name changes if you have MitID and a registered address in Denmark.
• In-person at Citizen Service (Borgerservice) – required if you do not have MitID, if you are newly arrived, or if the change involves foreign documents that must be checked in original.
• Through the parish office – some name changes and marital status updates for members of the Evangelical Lutheran Church are handled via the parish, but still end up in the CPR.

Always bring valid identification (passport or national ID card) and, where relevant, original civil status documents (marriage certificate, divorce decree, birth certificate, name change certificate) and official translations. Copies or unofficial translations are often not accepted and can delay the registration.

Typical processing times and confirmation

Simple address changes reported online are usually registered very quickly, often within a few days. More complex changes, especially those involving foreign documents or name changes, can take longer, depending on the municipality and whether additional verification is needed.

When the change is registered, you normally receive a digital confirmation in your e-Boks or a letter to your registered address. You can also log in to borger.dk and check your CPR data to ensure that everything is correct.

Why accurate CPR data matters for tax and everyday life

Incorrect or outdated CPR information can cause practical and financial problems, for example:

• wrong tax card or tax rate because SKAT uses incorrect marital status or municipality
• delays in salary payments if your employer cannot match your CPR data with bank information
• problems with health coverage if your address or municipality is wrong
• difficulties with banks, insurance companies or pension funds when your name does not match official registers

If you are unsure how a change in your personal situation will affect your tax position or registration duties in Denmark, it is worth seeking professional advice before you submit the change. Correctly updated CPR data is the basis for proper tax calculation, social security coverage and smooth everyday functioning in Denmark.

Protection of personal data and safe use of your CPR number

Your CPR number is the key to almost every public and many private services in Denmark. Because it uniquely identifies you in the Danish system, it is also highly sensitive personal data. Knowing how it is protected and how to use it safely will help you avoid identity theft, fraud and problems with authorities.

How your CPR number is protected in Denmark

In Denmark, the CPR number is protected by the CPR Act and the General Data Protection Regulation (GDPR). Public authorities and private companies may only request and process your CPR number when they have a clear legal basis or a documented, necessary purpose. They must:

• Store your CPR number securely and limit access to authorised staff only
• Use it only for the specific purposes for which it was collected (for example tax, salary, health care, banking)
• Not share it with third parties without a legal basis or your valid consent
• Delete or anonymise it when it is no longer needed for the original purpose, subject to statutory retention rules

As a data subject, you have the right to know who processes your CPR number, for what purpose, and to request access to, correction or in some cases deletion of your data.

Who is allowed to ask for your CPR number

In practice, you will be asked for your CPR number by many institutions, but not everyone is allowed to demand it. It is normal and lawful for the following to request your CPR number:

• SKAT (the Danish Tax Agency) and other public authorities
• Your employer (for salary, tax and pension reporting)
• Banks and mortgage institutions (for identification and reporting to authorities)
• Health services (GP, hospital, dentist with public agreement, insurance-funded treatment)
• Insurance companies, pension funds and unemployment funds (A‑kasse)
• Educational institutions and some housing associations

Shops, restaurants or online stores usually do not need your CPR number. If a private company outside the above categories asks for it, you can ask why it is necessary, on what legal basis they process it, and whether another form of identification is possible.

Safe everyday use of your CPR number

Because the CPR number is used together with MitID, NemKonto and other systems, it can be misused if it falls into the wrong hands. To reduce the risk:

• Do not carry your CPR number visibly (for example on a keyring or open card in your wallet)
• Do not send your CPR number in unencrypted email or through unsecured messaging apps unless absolutely necessary
• Never share your CPR number, MitID login or one‑time codes over the phone, SMS or email – public authorities and banks do not ask for this information in this way
• Check that websites asking for your CPR number use a secure connection (https and a valid certificate)
• Log out of public computers and do not save CPR‑related data in browsers on shared devices

CPR number, MitID and digital self‑service

Your CPR number is closely linked to MitID, which you use to log in to public self‑service (for example borger.dk, skat.dk) and many private services. To protect this digital identity:

• Install the MitID app only from official app stores and keep it updated
• Use a strong, unique PIN and do not share it with anyone
• Activate notifications from your bank and MitID so you can quickly detect suspicious logins or transactions
• Immediately block or suspend MitID if you suspect that your CPR number or login details have been compromised

Recognising attempts at fraud and identity theft

Scammers sometimes try to obtain CPR numbers to open bank accounts, take loans or access tax and benefit information in someone else’s name. Be particularly careful if you:

• Receive unsolicited calls, emails or SMS claiming to be from SKAT, your bank or the police asking for your CPR number or MitID details
• Are pressured to act quickly “to avoid a fine” or “to secure your account”
• Are offered a job or rental contract where you are asked to send a copy of your ID and CPR number to a private email address or via social media

In such situations, end the contact and call the official number of the authority or company to verify whether the request is genuine.

What to do if your CPR number is misused

If you suspect that someone is misusing your CPR number or has obtained it without your consent, you should act quickly:

• Contact your bank to check for unknown transactions and to block cards or accounts if necessary
• Log in to skat.dk and check for unusual changes in your tax information, employment data or registered income
• Check your digital mail (e‑Boks) for letters about loans, contracts or registrations you do not recognise
• Report the incident to the police and keep documentation of suspicious emails, messages or contracts
• Contact the company or authority where the misuse occurred and ask them to block further use and investigate the case

You can also contact the Danish Data Protection Agency (Datatilsynet) if you believe your CPR number has been processed unlawfully or insufficiently protected by an organisation.

How a Danish accountant can help you protect your data

For employees and entrepreneurs, the CPR number is used in many financial and tax processes. A professional accounting office in Denmark can help you by:

• Ensuring that your CPR number is used correctly in salary, tax and VAT reporting
• Setting up secure communication channels for exchanging documents that contain your CPR number
• Explaining when authorities or business partners are legitimately allowed to request your CPR number
• Monitoring correspondence from SKAT and other authorities so that you can quickly react to irregularities

With the right procedures and awareness, your CPR number remains a safe and practical tool for living and working in Denmark, instead of a source of risk.

Consequences of not having a CPR number when living or working in Denmark

Living or working in Denmark without a CPR number is technically possible for a short time, but in practice it makes everyday life and proper tax settlement very difficult. The CPR number is the key to almost all public and many private services. Below we explain the most important consequences of not having a CPR number and why it is worth obtaining it as soon as you become tax resident or start regular work in Denmark.

Limited access to healthcare and social benefits

Without a CPR number you cannot be registered in the Danish National Register and you do not receive the yellow health insurance card. This means:

• no permanent general practitioner (family doctor) assigned
• no access to the public digital booking systems for medical appointments
• in many cases, the need to pay the full cost of treatment as a private patient and then try to claim reimbursement from your home country or private insurance

Without a CPR number you also cannot receive most social benefits administered by Udbetaling Danmark and the municipalities, such as child benefits, housing benefits or certain sickness and unemployment benefits, even if you otherwise meet the conditions.

Problems with employment, salary and tax settlement

Employers in Denmark are obliged to report salary information to the Danish Tax Agency (Skattestyrelsen) via the eIncome system. This is normally done using your CPR number. If you do not have one:

• your employer may be forced to withhold tax at a high default rate, often around 55–56%, because no individual tax card can be created for you
• you cannot log in to skat.dk with MitID to check or correct your preliminary income assessment (forskudsopgørelse)
• you risk paying too much tax during the year and having to wait for a refund until your situation is clarified and your CPR number is issued

In some industries employers simply refuse to hire workers without a CPR number, because it complicates payroll, reporting and workplace insurance.

Difficulty opening a bank account and receiving salary

Most Danish banks require a CPR number to open a standard personal account with NemKonto status. Without it:

• you may only be able to open a limited, more expensive or temporary account, or be refused entirely
• your employer may have problems paying your salary to a foreign account, especially if they use automatic payroll systems configured for Danish accounts
• you cannot set up a NemKonto, which is needed for receiving tax refunds, certain benefits and other public payments

This can lead to delays in receiving salary, higher fees for international transfers and practical problems with everyday payments in Denmark.

No access to digital public services (MitID, e-Boks)

Most communication with Danish authorities takes place digitally via e-Boks and self-service portals that require MitID. To obtain MitID as a resident, you normally need a CPR number. Without it:

• you cannot log in to skat.dk, borger.dk or many municipal services
• you may miss important letters about tax, registration, deadlines or fines, because they are sent to e-Boks linked to a CPR number
• many applications (for benefits, permits, changes of address) must be submitted on paper or in person, which is slower and more error-prone

Problems with rental contracts and everyday contracts

Landlords, utility companies and telecom providers usually ask for a CPR number to verify identity and perform credit checks. Without it you may encounter:

• difficulties signing a long-term rental contract or registering your address in the folkeregister
• problems setting up electricity, internet or mobile subscriptions, or the need to pay higher deposits
• limited access to online self-service for contracts, because many systems are linked to CPR and MitID

Without registered address and CPR number, you also cannot obtain the yellow health card and you may have problems proving residence for tax or immigration purposes.

Unclear tax status and risk of penalties

If you live or work in Denmark but do not have a CPR number, it becomes harder for the tax authorities to correctly assess your tax obligations. This may lead to:

• incorrect classification as a limited or full tax resident, and therefore wrong tax calculation
• missing or delayed tax cards, resulting in excessive withholding or, conversely, underpayment of tax
• interest and possible surcharges if tax is paid too late or not reported correctly because you could not access digital services

Even without a CPR number you are still obliged to pay Danish tax on income earned in Denmark according to applicable rules and thresholds. Lack of a CPR number does not release you from tax obligations, it only makes fulfilling them more complicated.

Limited rights for accompanying family members

If you move to Denmark with your family and only some of you obtain CPR numbers, the others may face serious limitations. Without a CPR number family members may:

• have no access to the public healthcare system on the same terms as residents
• be unable to register children in public daycare or school in the standard way
• have difficulties proving family relationship and residence when applying for residence cards or benefits

When a CPR number is not strictly required – and why it still matters

For very short stays, such as brief business trips or seasonal work under certain conditions, it is sometimes possible to work and pay tax using a temporary identification number or foreign TIN instead of a Danish CPR number. However, this solution:

• is usually limited in time and scope
• does not give full access to the Danish welfare system and digital services
• often leads to higher administrative burden for both the employee and the employer

For anyone who actually lives in Denmark or works here on a regular basis, obtaining a CPR number is practically essential to avoid unnecessary costs, delays and legal uncertainty.

If you are unsure whether you are entitled to a CPR number or how your tax situation looks without it, it is worth seeking professional advice. Correct registration at the right time protects you from problems with the tax authorities, employers and public institutions and makes everyday life in Denmark significantly easier.

Deregistration and what happens to your CPR number when you leave Denmark

When you move away from Denmark, you cannot simply stop using your CPR number and assume everything closes automatically. You must actively deregister your address and, in some cases, your tax and social security obligations. Doing this correctly helps you avoid unexpected tax bills, letters from Danish authorities and problems with future returns to Denmark.

Do you lose your CPR number when you leave Denmark?

Your CPR number is not deleted when you leave Denmark. It remains in the Danish Civil Registration System for life and keeps its original digits. What changes is your status in the system:

• you are deregistered from your Danish address (no longer resident in Denmark)
• you are removed from the local municipality’s population register
• you lose access to most rights that depend on residence, such as the yellow health card and a Danish GP

If you later move back to Denmark and register a new address, you normally receive the same CPR number again.

How and when to deregister your address (folkeregister)

If you plan to live abroad for more than 6 months, you must report your move to the Danish Civil Registration System. In practice, you deregister through your municipality:

• Online – if you have MitID, you can report your move abroad digitally via borger.dk
• In person – if you do not have MitID, you must contact Citizen Service (Borgerservice) in your municipality before departure

In most cases, you should deregister no later than 5 days after leaving Denmark. Some municipalities recommend reporting the move a few weeks before departure with the actual moving date in the future. If you fail to deregister, you may still be treated as resident for certain administrative and tax purposes.

What happens to your yellow health card and access to healthcare?

After deregistration, your yellow health card (sundhedskort) is no longer valid. You are removed from the list of patients of your Danish GP, and you lose access to publicly funded healthcare as a resident. In emergencies, you can still receive acute treatment, but you may be charged if you are no longer covered by Danish or EU rules.

If you move to another EU/EEA country or Switzerland, your health coverage will usually be based on the rules of your new country of residence. If you move outside the EU/EEA, you should arrange private health insurance, as the Danish system will not cover you once you are deregistered.

CPR number and tax when leaving Denmark

Deregistering your address does not automatically end all tax obligations in Denmark. You may still be taxed in Denmark on certain types of income, for example:

• salary from work physically performed in Denmark
• income from Danish real estate (rental or sale)
• some pension payments and other Danish-source income

Before leaving, you should:

• update your tax information with the Danish Tax Agency (Skattestyrelsen) in skat.dk or by contacting them directly
• check whether you are leaving the Danish full tax liability regime and becoming only limited tax liable
• make sure your preliminary income assessment (forskudsopgørelse) and tax card are updated so your employer withholds correctly until your last working day

After the end of the tax year, you will still receive an annual tax assessment (årsopgørelse) in your skat.dk inbox. If you are entitled to a refund, it will be paid to your registered bank account. If you owe tax, you must pay within the deadlines set by Skattestyrelsen to avoid interest and surcharges.

Bank accounts, NemKonto and MitID after deregistration

Your CPR number continues to be used by banks and public authorities, even when you live abroad. In many cases it is useful to keep a Danish bank account and NemKonto active, especially if you expect:

• tax refunds or corrections from Skattestyrelsen
• payments from Danish employers, pension funds or authorities

MitID access can usually be kept while abroad, but you must maintain valid identification and contact details with your MitID provider and bank. Without MitID, handling tax matters and public correspondence from abroad becomes more complicated.

Social benefits and pensions when leaving Denmark

When you deregister and move abroad, most Danish social benefits linked to residence stop, for example:

• cash benefits (kontanthjælp)
• unemployment benefits (dagpenge) from a Danish unemployment fund, unless specific cross-border rules apply
• child benefits (børne- og ungeydelse), unless you fall under EU coordination rules and still pay Danish social contributions

State pension rights you have already earned in Denmark are generally not lost. However, payment of the pension abroad depends on your total insurance periods, the country you move to and applicable international agreements. It is important to inform Udbetaling Danmark and your pension providers about your move and new address.

Keeping your CPR data up to date while abroad

Even after deregistration, authorities and financial institutions use your CPR number to identify you. You should therefore:

• inform relevant authorities and banks of your new foreign address
• update your email and phone number in digital self-service solutions where possible
• keep copies of your CPR registration documents, tax assessments and employment contracts for future reference

If you later change your name or marital status abroad, these changes are not always automatically reflected in the Danish CPR. In many cases you must provide official foreign documents (with apostille and, if necessary, translation) to have your CPR data updated.

Returning to Denmark and reactivating your CPR number

If you come back to Denmark to live and work, you normally do not receive a new CPR number. Instead, you:

• register your new Danish address with the municipality (online with MitID or at Citizen Service)
• are assigned a new GP and receive a new yellow health card
• are again considered resident for tax and social security purposes from the date of registration, subject to tax rules

If you have been away for many years, authorities may ask for additional documentation (passport, residence permit, employment contract or rental agreement) when you return. Once your address is registered, your CPR number becomes fully active again in all public systems.

Proper deregistration and understanding what happens to your CPR number when you leave Denmark helps you close your affairs cleanly and avoid double taxation, loss of rights or administrative problems if you decide to return in the future.

Conditions for obtaining a CPR number

To obtain a CPR number in Denmark, you must meet several key requirements. First and foremost, you must be registered in Denmark, whether permanently or temporarily, as a CPR number is only granted to those registered in the Danish population registry system. It is also necessary to have the appropriate documents, including proof of residence in Denmark, which can be in the form of a lease agreement, and a valid passport or ID card. In addition, a residence permit is required, which is issued by the relevant immigration authorities and may vary depending on the type of stay, such as tourism, work or study.

European Union citizens have the right to stay in Denmark without registration for the first 3 months. If you plan to extend your stay or seek employment, you must apply for residency registration before this period expires. For temporary residence, such as seasonal work, you will receive a kildeskattenummer - a taxpayer number for paying withholding tax - instead of a CPR number.

If you come to Denmark with your family, each family member, including children, must be assigned their own CPR number. Individual applications for each family member are required. If you are applying for a CPR number on behalf of another person, you must provide a written power of attorney that authorizes you to represent that person in the registration process.
