National identity number


A national identity number is an ID number for you with a residence permit who are going to live in Norway for more than six months.

What do I need a national identity number for?

We have two kinds of identification numbers in Norway: national identity numbers and D numbers. Some public and private companies require a Norwegian identification number to access their services. With an identification number, you can, for example, open a bank account, get a general practitioner (fastlege) (external website), rent a place to live, pay taxes and be able to vote in elections.  

The D number consists of 11 numbers. The Norwegian Tax Administration is responsible for the scheme with identification numbers in Norway (external website), including D numbers.  

How do I get a national identity number?

  • If you have been granted a residence permit in Norway, UDI will send information to the Tax Administration that you will reside in Norway. After you get your residence card, they will decide if you get a national identity number or a D number. You will receive information about this in a letter from the Tax Administration about two to six weeks after you have met with the police to order your residence card.

I have a national identity number but am registered as emigrated from Norway. What do I do?

There are several reasons why you may be registered as emigrated from Norway in the National Register. If you are registered as emigrated because your permit has expired, but you have a new application in process now, you can ask UDI to contact the Tax Administration and have the registered emigration is corrected (external website).  

UDI can only do this if we believe that you had legal residence when you were registered as emigrated in the National Register. If there are other reasons why you have been registered as emigrated in the National Register, you must contact the Tax Administration (external website).
