Registration in connection with moving
Everyone who moves to Norway from another country, between two Norwegian municipalities, or to another place in the same municipality, is obliged to notify the population register within eight days. The population register is part of the tax office. When you move to Norway, you must go to the tax office.
D-number
If you are staying in Norway for up to six months, you will be given a D-number. This is an identification number for all foreign nationals who live in Norway for up to six months. Among other things, the D-number is used when you apply for a tax deduction card.
Personal identity number
As a rule, personal identity numbers are given to persons who are born in Norway or who are registered as settled here. A personal identity number may also be given to Norwegian nationals who live in another country when it is a condition for them being issued a Norwegian passport.
