CPR – Registration in Denmark

In Denmark each person has a personal registration number, which is called a CPR number (Social Security Number). See how you can get a CPR number.

The CPR number is essential in relation to any contact with the Danish authorities and especially in connection to tax and social security issues.

If you intend to stay for a period of three months or more (six months if within EU/EEA or Nordic countries), you have to notify the municipal authorities (Folkeregistret).
