D-number

Let us explain. A D-number is a temporary personal identification number, which allows you to receive different services. It is typically granted to those who are planning on staying in Norway for less than 6 months.

If you are a EU/EEA citizen, you will most likely receive your D-number when you register to pay for taxes at the Tax Administration (Skatteetaten) upon securing employment.

For other internationals, you can apply for a D-number as soon as you have been granted a residence permit in Norway. When you have been granted a residence permit, you need to book an appointment with the police to order your residence card.

You can expect to receive your D-number about two weeks after the appointment with the police. There are also other organizations and institutions who can issue D-number - see the complete list here.

National identification number

Norway's eleven digit fødselsnummer (national identification number/birth number) is the national identity number used for all manner of administrative tasks in the country. Norwegians are assigned one at birth and immigrants must obtain one.

If you are planning on working in Norway for more than 6 months, you can apply for a national identification number. The Norwegian Tax Administration assigns national identity numbers and decides whether you meet the conditions for being registered as a resident in Norway. You might also be given a personal identification number right away, depending on your situation.

A D-number and national identification number give you different types of rights and access to public services. You can read about the differences here.
