Folkeregister Registration in Denmark

Before you can get a CPR number, a health card, a bank account, or a tax card in Denmark, you need to be registered in the Civil Registration System (CPR) through your municipality's folkeregister (registration office). This is the official record of who lives where in Denmark, and registering is one of the first things you must do after arriving.

The registration happens in person at your local Borgerservice (Citizens' Service) or an International Citizen Service centre.

What Is the Folkeregister?

The Civil Registration System (Det Centrale Personregister, CPR) is Denmark's central civil registry; the folkeregister is the municipal office that registers you in it. CPR records:

• Your name, date of birth, and sex
• Your current and historical addresses in Denmark
• Your family relationships (spouse, children, parents) if relevant
• Your nationality and citizenship status

Every public agency in Denmark — SKAT (tax), the health system, the schools, the pension system — draws from this single register. When you register, you are entering the Danish system at the root level. The CPR number you receive is your identifier across all of them.

Who Must Register

You are required to register in the Folkeregister if you intend to stay in Denmark for more than three months (more than six months for EU/EEA, Swiss and Nordic citizens) and you have the right to do so. This includes:

• EU/EEA citizens working, studying, or living in Denmark with sufficient means
• Non-EU citizens who have received a Danish residence permit
• Family members joining a registered resident

You are not required to register if you are in Denmark as a tourist or for a short-term visit under 90 days (for EU/Schengen visitors) or under your visa duration (for visa-required nationalities).

The 5-Day Rule

Danish law specifies that you must register within five days of having an address in Denmark and, for non-Nordic citizens, a residence permit or EU residence document. In practice, book your appointment as soon as you have your address and, if you need one, your permit or EU residence document.

The practical interpretation: register as soon as you can, and as soon as you have a confirmed address. Authorities understand the logistical constraints. What they do not want is someone living in Denmark for months without registering. Apply or book as soon as you have a signed rental contract and, if you need one, your residence permit or EU residence document.

Before Your Appointment: What You Need

A Fixed Address

You cannot register without a real, fixed residential address in Denmark. This means:

• A signed rental contract showing your name, the property address, and the rental period
• Or a letter from the property owner confirming you live there (if informal arrangement)
• Or, in some communes, a letter from your employer if they are providing accommodation

If you are staying with a friend, they need to provide written confirmation that you live at their address, and they may also need to sign the form at Borgerservice.

Documents to Bring

For EU/EEA citizens:

• Valid passport or national identity card (EU citizens may use ID card)
• Proof of address (signed rental contract or letter from landlord/host)
• Your EU residence document from SIRI (Nordic citizens do not need one)

For non-EU citizens:

• Valid passport (same as on your residence permit)
• Danish residence permit (physical card or official SIRI confirmation letter)
• Proof of address (signed rental contract)
• Employment contract or documentation matching your permit type

Booking Your Appointment

1. Go to your municipality's website or to borger.dk
2. Search for "Borgerservice" or "Tilmelding til folkeregisteret" (registration in the civil register)
3. Choose your local office (based on your address postcode)
4. Book an appointment for "Tilmelding / CPR-nummer" or similar — descriptions vary by municipality

In Copenhagen, newcomers from abroad apply for CPR registration through International House Copenhagen (ihcph.kk.dk). Other major municipalities have equivalent portals.

Appointment availability varies, so book as early as possible.

What Happens at the Appointment

A case officer will:

1. Review your documents (passport, rental contract, and your residence permit or EU residence document)
2. Verify your address exists in the Danish address system (they type it in — make sure you know your exact address including apartment number and floor)
3. Enter your details into the Civil Registration System
4. For EU citizens: check the EU residence document you must already have obtained from SIRI (apply via nyidanmark.dk) before this appointment

At the end of the appointment, you receive your CPR number. Your yellow health card is then mailed to your registered address.

Special Registration Situations

Students

University students register the same way. EU/EEA and Swiss students first get their EU residence document from SIRI (with their letter of acceptance); non-EU students bring their residence permit.

If you are in student housing, the landlord is often the university accommodation office. Get a formal rental contract from them before your appointment.

Au Pairs

Au pairs in Denmark register through the same Folkeregister process. Note that au pairs need a specific au pair residence permit (non-EU nationals) or to meet EU free movement criteria (EU nationals).

Freelancers and Self-Employed

EU/EEA and Swiss citizens apply to SIRI for an EU residence document as self-employed persons (SIRI asks for the business's registration and a budget or accounts) before registering. Non-EU citizens need a residence permit that covers self-employment.

Staying With a Host (Not Renting)

If you are staying with a friend or partner who owns or rents the property, you will need a signed letter from that person (the primary resident) confirming you live there. In some communes, the primary resident must accompany you to the Borgerservice appointment and sign a form in person. Check with your local Borgerservice before the appointment.

After Registration

Once registered:

• Your CPR number is given at the appointment
• Your health card arrives by post approximately 2 to 3 weeks after registration
• You can now open a Danish bank account
• You can apply for MitID once you have CPR
• You can file for a tax card via skat.dk

If you move to a new address within Denmark, you must notify your new municipality within five days. Address changes must normally be done online via borger.dk with MitID; if you cannot use the digital service (for example, you have no MitID), Borgerservice can help.

Key Takeaways

• Registration happens in person at Borgerservice or an International Citizen Service centre (in Copenhagen, International House).
• Apply as soon as you have your address and permit or EU residence document; in Copenhagen the online application can take 2–3 weeks before you get a booking link.
• You need a fixed residential address (signed rental contract) before you can register.
• EU/EEA and Swiss citizens bring their passport or ID card, rental contract and the EU residence document from SIRI.
• Non-EU citizens need their issued residence permit plus proof of address.
• Your CPR number is issued as a result of this registration, at the appointment.
• If you stay with a friend rather than renting, get a signed letter from them before the appointment.
