National identity number

A national identity number is an ID number for you who have a residence permit and are going to live in Norway for more than six months. You need it when you are in touch with different Norwegian  authorities.

What do you need your national identity number for?

With a national identity number you can for example open a bank accountget a regular GP (fastlege), rent a place to live, pay your taxes and be able to vote at elections

A national identity number is an eleven digit ID number, and the last five digits are called a "personal number".

When do you get a national identity number?

  • If you have been granted a residence permit in Norway, the Tax Administration 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.
  • If you have a residence in Norway according to the EU/EEA regulations, you will receive your national identity number from the Tax Administration when you meet there, after you have registered with the police.

See information about moving to Norway at the Tax Administration (external website).

Have you got a national identity number, but are you still registered as moved from Norway in the National Registry? 

There may be several reasons why you have been registered as moved from Norway in the National Registry.  

If you are registered as moved from Norway because your residence permit is no longer valid and you have a new application that is being processed now, you may ask the Norwegian Directorate of Immigration (UDI) to notify the Norwegian Tax Administration, so that they correct the registered relocation. This may only happen if the Norwegian Directorate of Immigration believes you were legally in Norway when you were registered as moved from Norway. 

If there are other reasons why you are not registered in the National Registry any more, you need to contact your local Norwegian Tax office. (external website)

Your national identity number and birth date are not the same 

Your national identity number is not necessarily the same as your birth dateThe Norwegian Directorate of Immigration does not change your birth date when it’s not the same as your national identity number. 

Do you have a D number? 

What is a DUF number? 

Everyone who applies for protection (asylum) or for a residence permit in Norway will be assigned a DUF number. The DUF number is your registration number in the computer system of the Norwegian Directorate of Immigration (the UDI).
