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.

You need the national identity number for example to open a bank account, to get a regular GP (fastlege), to rent a place to live, to pay your taxes and to be able to vote at elections

What if you have not got a national identity number? 

When you are granted a permit for the first time, in addition to the decision you will receive information on how to get a national identity number. You will normally need to contact your local Norwegian Tax Administation office to notify that you are moving to Norway. 

Please check the information that follows your decision what applies to you.

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

There may be several reasons why you have been registrered 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If you are registered as moved from Norway because your residence permit is no longer valid and you have a new application that is being processed now, you may ask the Norwegian Directorate of Immigration (the UDI) to notify the Norwegian Tax Administration, so that they may re-register you into the National Registry. 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)

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).
