Civil Registration Number
In Denmark all citizens have a civil registration number, called CPR-NUMMER.
If your spouse/partner and any children accompany you, they must each have a civil registration number.
CPR is short for Central Person Register, and you have to provide your civil registration number when you need to contact public authorities in Denmark. The civil registration number consists of ten digits, the first of which contain your date of birth, and it is personal and unique. The number is used by all authorities as a number for identification and as a case number.
The Civil Registration number is of vital importance if you want to obtain a national health insurance card, a tax card, and you will also need it when opening a bank account.
