The CPR number or ”yellow card” as many refer to, is a personal ID number, which is used by all public organizations and institutions. You will need a CPR card in order to work in Denmark and use the health care system. Although, in case of emergencies, you do not need your CPR number to get hospital care.
The CPR has existed since 1968, as a registry of all people who live or have lived in Denmark, therefore the name Det Centrale Personregister, which means “The central registry of residents”.The CPR-number is a 10 digit number. The first 6 is your birth date: date/month/last 2 digits of year of birth. The last 4 is a random number.
The CPR-number can be obtained at the civil registration office (Folkeregisteret). You need to bring your residence permit and some type of ID, such as a passport.
Contact your local municipality in order to find out which civil registration office you need to go, in order to apply for the CPR-number.
