In order to obtain either a national ID number or a D number, you must do the following:
Your national ID number or D number will be shown on your tax deduction card.
What is the difference between a national ID number and a D number?
- Everyone who is resident in Norway will be allocated a national ID number, which they will keep for life. National ID numbers consist of 11 digits, of which the first six digits indicate the person's date of birth.
- Foreigners who come to work in Norway for less than six months will not be given a national ID number. Instead, they will be allocated a D number.
- If you intend to stay in Norway for more than six months, you must apply for a national ID number by reporting a move to Norway. If you have previously been allocated a D number, you must subsequently only use your national ID number.
- You must use your national ID number or D number every time you come to Norway to work. You must also state this number when you request a new tax deduction card.
Opening a bank account in Norway

- You should have a bank account in Norway that your employer can pay your salary into, and that the Norwegian Tax Administration can transfer any excess tax deductions into where applicable.
