How to Get a CPR Number in Denmark

Your CPR number is the single most important piece of admin you'll sort in Denmark. Without it, you cannot open a bank account, get a tax card, register with a GP, receive a health card, or access any government service. Everything else depends on this one number. Get it done first.

What Is a CPR Number?

CPR stands for Det Centrale Personregister — the Central Person Register. It is a 10-digit personal identification number that Denmark uses to track every resident in the country across all public systems: healthcare, taxation, education, social services, banking, and more.

The number has a specific format: DDMMYY-XXXX

The first six digits are your date of birth. The last four are a unique serial code. The final digit also encodes your sex: even for women, odd for men (though this convention is being phased out for non-binary residents).

Example: someone born on 15 March 1990 might have the CPR number 150390-4321.

Once issued, your CPR number does not change. It follows you for your entire life in Denmark.

Who Needs a CPR Number?

Anyone who intends to stay in Denmark for more than three months must register and receive a CPR number. This includes:

• EU/EEA citizens who are working, studying, or have sufficient means to support themselves
• Non-EU citizens with a valid residence and work permit
• Asylum seekers (through a separate process managed by the Danish Immigration Service)
• Researchers, au pairs, and family members joining a resident

If you are only visiting Denmark as a tourist for fewer than 90 days and have no intention of working or residing, you do not need a CPR number.

EU/EEA Citizens vs Non-EU Citizens

Your eligibility and documentation requirements differ depending on your nationality.

EU/EEA and Swiss citizens have the right to live and work in Denmark under EU free movement rules. You do not need a work permit, but you do need to register your right of residence if staying more than three months. CPR registration and the EU residence certificate can be done simultaneously at Borgerservice.

Non-EU citizens must already hold a valid Danish residence permit before they can register for a CPR number. You cannot get a CPR number on arrival if your permit is still being processed — you need the physical permit or a confirmation letter from the Danish Immigration Service (Styrelsen for International Rekruttering og Integration, SIRI).

Where to Register: Borgerservice

You register for a CPR number at your local Borgerservice (Citizens' Service) office. This is a municipal office — part of Denmark's commune (kommune) system. You must register at the Borgerservice in the commune where you will actually be living, not just the nearest or most convenient office.

To find your local office:

1. Go to borger.dk
2. Search for "Borgerservice" with your postcode or address
3. Book an appointment online — walk-ins are sometimes possible but not guaranteed

Copenhagen has multiple Borgerservice locations. The main one is at Dahlerupsgade 6, 1640 Copenhagen V, but residents are assigned to offices by postcode.

You must book an appointment in advance. Do not show up without one — you will almost certainly be turned away.

Book your Borgerservice appointment now:

• Copenhagen residents: Book online at kk.dk — select "Folkeregister" then "Tilmelding til folkeregisteret"
• All of Denmark: Find your local Borgerservice on borger.dk — enter your postcode to find your commune's office and booking page
• Direct CPR registration page: borger.dk — Register in the Civil Registration System

Most online booking systems show appointment availability 2–4 weeks ahead. Book your slot before you travel to Denmark if possible — appointments fill quickly in August and September.

What Documents to Bring

Bring originals, not copies. Borgerservice staff will check the physical documents. Scans or photos on your phone are not accepted.

For EU/EEA Citizens

Document	Notes
Valid passport or national ID card	Must be in date
Proof of address in Denmark	Rental contract or a letter from your host
Proof of your basis for registration	Employment contract, letter of enrolment from a university, or proof of sufficient funds (bank statement)

If you are registering as a family member of an EU citizen, bring the EU citizen's CPR number and documentation of the family relationship (marriage certificate, birth certificate).

For Non-EU Citizens

Document	Notes
Valid passport	Must match your residence permit exactly
Danish residence permit	The physical card or official confirmation letter from SIRI
Proof of address in Denmark	Signed rental agreement showing your name and address
Employment contract or other basis document	Matching the type of permit you hold

If your permit covers your family, each family member must register individually with their own supporting documents.

The Appointment Process

A Borgerservice appointment for CPR registration typically takes 15–30 minutes. Here is what happens:

1. Arrive a few minutes early. You may need to check in at a reception desk or kiosk.
2. A case officer will verify your documents.
3. They will enter your details into the Civil Registration System.
4. For EU citizens, you may receive your EU residence certificate on the same day (a printed document).
5. You will not receive your CPR number immediately. It is sent to your registered address by post.

The appointment itself is straightforward. Case officers in Denmark generally speak fluent English.

How Long Does It Take?

From the date of your appointment, expect your CPR number to arrive by post within one to two weeks. In some communes it is faster; in Copenhagen during busy periods (August/September, when many international students arrive) it can take slightly longer.

While you are waiting, your employer can still pay you — they can use your passport number or residence permit number as a temporary reference. However, without a CPR number, your employer cannot register you correctly in the tax system, which means the maximum tax rate (55%) will be applied to your salary until you provide your CPR and tax card.

If you urgently need your CPR number for a specific purpose (e.g., to sign a housing contract that requires it), contact your Borgerservice and explain the situation. In some cases they can provide a letter confirming your registration number.

Once You Have Your CPR Number

With your CPR number in hand, the rest of your Danish bureaucracy unlocks in a specific sequence:

1. Set up MitID — Denmark's digital identity system. You need your CPR number and a Danish phone number to activate it.
2. Open a Danish bank account — Most banks require CPR.
3. Get your tax card (skattekort) — Log in to skat.dk with MitID to file a preliminary income assessment.
4. Register with a GP (praktiserende læge) — Use sundhed.dk with your CPR number.
5. Receive your health card (sundhedskort) — Arrives by post, usually around the same time as CPR.
6. Designate a NemKonto — So the state can pay you tax refunds, benefits, and salary correctly.

None of these steps can start without the CPR number. Do not delay registering — book your Borgerservice appointment as early as possible after arriving, ideally within the first day or two.

Common Problems and How to Handle Them

"I don't have a permanent address yet." You need a registered address to get a CPR number. If you are staying in temporary accommodation (Airbnb, hotel), this will not work. You need a proper rental contract. Some expats ask their employer to provide a temporary address (e.g., the company's office address) — this is sometimes allowed but varies by commune.

"My residence permit hasn't arrived yet." If you applied from abroad and your permit is being processed, you need the official confirmation letter from SIRI. Contact SIRI to request one if your appointment date is approaching.

"I registered but never received my CPR letter." Contact your Borgerservice immediately. It may have been sent to the wrong address or returned to the office. Bring your appointment confirmation.

"My CPR number isn't working on skat.dk or sundhed.dk." Allow 24–48 hours after issuance for the number to propagate across government systems. If it's been more than three days, call the relevant agency directly.

Key Takeaways

• Your CPR number (DDMMYY-XXXX format) is the foundation of everything administrative in Denmark.
• Register at your local Borgerservice with original documents — book an appointment online in advance.
• EU/EEA citizens need proof of residency basis (job, study, or funds). Non-EU citizens need an issued residence permit.
• The number arrives by post within 1–2 weeks of your appointment.
• Without CPR, your employer will deduct 55% tax. Get this sorted as your absolute first priority.
• Once you have CPR, set up MitID immediately — most other services depend on it.
