Students staying in Norway for more than six months need to report a move to Norway and get a Norwegian ID number.
We do NOT recommend students who are staying for one semester to apply for an ID number.
Step 1: Pick up your residence permit/register with the police as soon as possible after arrival.
Step 2: After registering with the police, you must as soon as possible go to the Tax Office (Skatteetaten) in Kristiansand or Grimstad to report a move to Norway. You must fill in the form "Notification of move to Norway from abroad". Please see this webpage for the form and for information on what documents you need to bring.
Step 3: When your move has been reported, you will automatically receive a Norwegian ID number within 14-21 days.
