In Denmark each resident has a civil registration number, which is called a CPR number. CPR stands for Central Person Register. The CPR number is essential in relation to any contact with the Danish public authorities and especially in connection to tax and social security issues.
In order to get a CPR number your stay in Denmark must exceed 3 months. Also, you can’t be issued with a CPR number before you have found a place to live and actually live there. If you are a citizen from outside the Nordic countries, you must also have been issued with an EU residence document or have obtained a residence permit in order to be issued with a CPR number.
Your CPR number is issued by Citizen Service in the municipality you are moving to or at one of the International Citizen Service centres. You may have to apply for a CPR number online and book an appointment before appearing in person to complete the registration for your CPR number.
