What can you use an administrative CPR number for?

You need a CPR number in order to receive a Danish NemID.

For further information, see our NemID page.

A CPR number is also required when communicating with both public institutions, including the hospital service, and private companies in Denmark, since it is used as a form of identification / record number in the institutions’ and companies’ IT systems. For this reason, it is easier for institutions and private companies to process inquiries if a person has a CPR number.
