How do I get a D number or national identity number?
If you are a UK national who came to Norway before 1 January 2021 or as a family member to a UK national who came to Norway before 1 January 2021, you must contact the Norwegian Tax Administration to be assigned a D number or a national identity number.
You cannot contact UDI or the police to obtain a D number or a national identity number.
A D number (external website) is a temporary ID number. A national identity number (external website) is a permanent ID number.
If the Tax Administration believes you meet the requirements set for this, you will be assigned a national identity number from the Norwegian Tax Administration by reporting a move to Norway (external website).
