D-number is a number assigned to foreign nationals without a Norwegian national identity number, in need of some kind of identification to Norwegian authorities.

Only persons staying in Norway for less than six months can be assigned a d-number.

We can only request a d-number in cases where the request is related to registration in one of our registers or if there is a need to report in Altinn on behalf of an already registered participant.

Due to requirements for identification papers in order to be assigned a d-number, the application must be submitted by post. In addition to the application you have to enclose a confirmed copy of valid identification document, for instance a passport which is stamped and signed by the one who made the copy. The copy must show an original signature and stamp or else it will not be approved. In other words, we can not accept a copy of the stamp or the signature.

Who can certify a copy?

A copy may be certified by

  • a Norwegian public authority
  • a Nordic police authority
  • a Norwegian lawyer
  • a Norwegian state authorised or registered auditor
  • a Norwegian authorised accountant
  • a Nordic embassy
  • a foreign entity with notary powers
What does the identification paper have to contain?

Identification paper must contain

  • name
  • date of birth
  • photo
  • gender
  • nationality
  • date of expiry

Normally a passport or a national identity card will contain the required information as mentioned above.

It is important that the machine readable strip at the bottom of the passport shows on the copy of the passport.

The reverse side of the ID-card usually contains a machine readable strip. A certified copy of the reverse side of the card must also be enclosed.

The main rule is that the identification document must be issued by a public authority.

Do you already have a d-number?

If you already have a d-number, this is to be used in connection with registrations

If you do not have access to or have questions about your d-number, you may contact the National Registry at the Tax Administration.

The Tax Administration submits a confirmation of your d-number after this has been assigned. The confirmation will be submitted by post to the address you are registered with in the National Registry.
