What do I need the D number for?

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.  

We have two kinds of identification numbers in Norway: national identity numbers and D numbers. The Norwegian Tax Administration is responsible for the scheme with identification numbers in Norway (external website).

You can receive a D number when you need an identification number in Norway, but do not meet the criteria for being assigned a national identity number.

On the Norwegian Tax Administration's website you can find an overview of which authorities or businesses can request D numbers (external website).
