CPR (Centrale Personregister) number is unique to a person and is used as an ID in Denmark. A CPR number facilitates accurate linkage between all Danish national registers among all other things. Your CPR number consists of ten digits. The primary six digits are your date of birth and the last four are your unique identification number. The last digit of your CPR number indicates your sex. If it’s an odd digit you’re male, and if it’s a fair digit you’re female.
WHY?
Residents of Denmark are legally required to possess a CPR number. You may also notice that your CPR number grants you access to many services in Denmark. You may need it to open a checking account, get a Danish sign, borrow books at the library, cast off insurance and so on.
WHEN?
Non-EU/EEA citizens who intend to stay in Denmark for more than three months are required to register with the Danish Civil Registration System on arrival.
Nordic citizens, citizens of EU and EEA countries and Switzerland are required to register with the Danish Civil Registration System and obtain a CPR number within six months of their arrival in Denmark.
To obtain a CPR number you must have an address in Denmark, also present a range of documents counting on your current civil status (see below). Please note that if your documents aren’t in Danish, Norwegian, Swedish, English or German, you must bring an authorized translation of all these documents.

CPR Number Denmark: How to Register and Get Yours
The CPR number is the Danish equivalent of the Swedish personnummer, and nothing practical works without it. No CPR number means no health card, no Danish bank account, no MitID, no tax card. It is the first thing to sort out when you move to Denmark, and the thing most people underestimate.
Who needs a CPR number
You must register if your stay in Denmark will exceed three months. Stays of three months or less do not require registration. The clock is about intended length of stay, not how long you have been there, so plan the registration before you arrive rather than after.
The order matters, and this is where people lose weeks
CPR registration is the second step, not the first. What comes before it depends on your nationality:
- EU and EEA citizens must first obtain an EU registration certificate (EU-opholdsbevis) from SIRI, the Danish Agency for International Recruitment and Integration. Only then can you complete CPR registration at your local citizen service office.
- Non-EU citizens must first hold a valid residence permit from SIRI. The CPR registration follows.
- Nordic citizens, including Swedes, have a simpler route and register directly, though requirements should be confirmed with the specific municipality.
Arriving and going straight to Borgerservice without the SIRI document is the single most common wasted trip. You will be turned away.
Documents to bring
Bring originals, not copies. Municipalities routinely refuse photocopies.
- Passport or national ID card
- Lease agreement, or a lodging host statement if you are staying with someone
- Your EU registration certificate, or residence permit for non-EU citizens
- Birth certificates for any children
- Marriage certificate, if married
Where you register depends on your municipality. Several, including parts of Copenhagen and Frederiksberg, direct new arrivals to International House Copenhagen rather than the local office. Confirm the correct location before travelling.
What the CPR number unlocks
- The health card (sundhedskort, the yellow card) and with it a doctor and access to the healthcare system
- A Danish bank account and a NemKonto, the account public payments are made into
- MitID, the digital identification used for banking, public services and most online administration
- A tax card (skattekort), without which you are taxed at a substantially higher rate
- Registration with your municipality for schools, childcare and everything else
Moving between Sweden and Denmark
The Øresund region makes it common to live on one side of the bridge and work on the other. That situation raises questions the two systems do not answer neatly: which country you are taxed in, where you are socially insured, and whether you need a personnummer, a CPR number or both. Getting this wrong is expensive and awkward to unwind afterwards.
If your move involves both countries, take advice before you register anywhere. The sequence you follow determines the outcome.
Frequently asked questions
How long does it take to get a CPR number?
The CPR registration itself is normally quick once you appear with the right documents. The waiting time sits in the step before it, obtaining the SIRI registration certificate or residence permit. Plan around that, not around the municipal appointment.
Can I get a CPR number without an address in Denmark?
Registration requires documented accommodation, either a lease or a lodging host statement. Securing housing is therefore part of the CPR process, not something separate from it.
Do I need a CPR number for a stay under three months?
No. Registration is required where the stay exceeds three months.
Is a CPR number the same as a personnummer?
They serve the same function in their respective countries, Denmark and Sweden, but they are separate systems. Holding one does not give you the other.
What if I am an EU citizen married to a non-EU national?
Your spouse’s position derives from your right of free movement and follows a different track, usually a residence card rather than a registration certificate. This is where families most often run into difficulty, and where advice is worth taking early.
