Get your CPR number, the key to everything
What a CPR number actually is
CPR stands for Det Centrale Personregister - the Central Person Register. Your number is ten digits: the first six are your date of birth, the last four a unique identifier. It's the thread that ties together your tax record, health care, bank account and every dealing with a public authority. Get this, and everything else falls into place. Don't, and nothing does.
Who needs one, and when
If you're staying longer than three months (six months if you're from an EU/EEA or Nordic country), you're required to register. The clock matters:
- EU/EEA citizens - register after settling, and you'll need an EU residence document (registration certificate) from SIRI first.
- Non-EU citizens - you must have your residence permit already, and register within five days of taking up residence.
- Nordic citizens - no residence document needed; register if staying over six months.
Where to go
Register free at an International Citizen Service (ICS) centre - there are six: Copenhagen, Aarhus, Aalborg, Odense, Sønderborg and Esbjerg. Or use your local Borgerservice. ICS is the smoother route for internationals because tax, CPR and residence services sit under one roof. Most locations book online, and several let you upload documents in advance.
What to bring
Book one appointment per person - a family of four needs four bookings. Bring originals:
- Passport or national ID
- Proof of your Danish address (a signed rental contract)
- EU registration certificate (EU/EEA) or residence permit (non-EU)
- Marriage or birth certificates if registering family
What you get, and what's next
At most locations outside Copenhagen you'll walk out with the number the same day. Then:
- Yellow health card (sundhedskort) arrives by post in two to four weeks, showing your assigned doctor. Put your name on your letterbox or it gets returned.
- MitID - set it up at the same appointment if you can. See setting up MitID.
- Bank account and tax card - both need the CPR. See opening a bank account.
