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 Folkeregister — the Danish Civil Registration System. This is the official record of who lives where in Denmark. Every municipality maintains its own section of this register, and registering is one of the first things you must do after arriving.

The registration happens at your local Borgerservice (Citizens' Service) office, in person, with original documents.

What Is the Folkeregister?

The Folkeregister (formally Det Centrale Personregister or CPR) is Denmark's central civil registry. It 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), SKAT, 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 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 at Borgerservice within five days of arriving at your address in Denmark. In practice, this is very difficult to comply with literally — Borgerservice appointment slots are often booked out more than five days in advance, and you need to have a fixed address before you can register.

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. Book your Borgerservice appointment the day you arrive or as soon as you have a signed rental contract.

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

Airbnb, hotel, or hostel addresses do not qualify. 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)
• Proof of the basis for your registration — one of:
  • Employment contract (signed, showing Danish employer, salary, start date)
  • University enrollment letter
  • Proof of sufficient funds (bank statement showing you can support yourself — typically 3 months of living costs)
  • For family members: evidence of relationship to the registering EU citizen (marriage certificate, birth certificate)

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

Bring originals only. Borgerservice will examine the original documents. Do not bring photocopies or digital versions — they will not be accepted.

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, the main Borgerservice website is kk.dk/borgerservice. Other major municipalities have equivalent portals.

Appointment availability varies. In summer (July–September), when international arrivals peak, slots can be booked 1–2 weeks out. Book as early as possible.

What Happens at the Appointment

A case officer will:

1. Review your documents (passport, rental contract, employment/basis documentation)
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: issue your EU residence certificate (registration certificate) at the same appointment, or advise you to apply online through nyidanmark.dk

The appointment typically takes 20–30 minutes. Staff speak English at all major offices.

At the end of the appointment, you will not receive your CPR number immediately. It is mailed to your registered address within 1–2 weeks.

Special Registration Situations

Students

University students in Denmark register the same way, but use their enrollment letter as proof of basis. Your university's international office can usually provide a specific letter for Borgerservice. Confirm with them what format is required — some communes ask for it on official letterhead with a stamp.

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. Your host family's signed au pair contract and confirmation that you live at their address serves as both proof of basis and proof of address. 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

If you are moving to Denmark as a self-employed person, you need to show you have sufficient funds to support yourself or that you have active business income in Denmark. EU citizens can register on the basis of self-employment with evidence of business activity (invoices, business registration, clients). Non-EU citizens typically need a specific self-employment or business visa.

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 arrives by post (1–2 weeks)
• Your health card arrives by post around the same time
• 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 update your registration at Borgerservice within five days. Address changes can also be done online via borger.dk with MitID.
