What do I need the D 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 and pay taxes.  

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 D number? 

• If you are an EU/EEA citizen and are coming to Norway to work for less than six months, you will receive a D number when you apply for a tax card at the Norwegian Tax Administration (external website). 
• If you have been granted a residence permit in Norway, you will receive your D number in a letter from the Norwegian Tax Administration about two weeks after you attended the appointment with the police to order your residence card. 
• If you are applying for protection (asylum), you will receive a D number when you come to Norway. You will get it either from UDI or from the police immigration service (PU) when you are registered. 

You can read more about D numbers on the Norwegian Tax Administration's website (external website). 

I am going to stay in Norway for longer than six months. What do I do?

Then you may be entitled to get a national identity number. 

The Norwegian Tax Administration assigns national identity numbers and decides whether you meet the conditions for being registered as a resident in Norway. If you are assigned a national identity number, you should use your national identity number instead of your D number (external website). 

Suppose you have been granted a residence permit for six months or more, and you think that you should have been registered as a resident in Norway and received a national identity number instead of a D number. In that case, you can report a move to Norway (external website) 

Is a DUF number the same as a D number?   

A DUF number is not the same as a D number. The DUF number is your registration number in UDI’s registration system (external website).
