Change of name
You can change your first name, middle name and surname. Please note that a middle name is not a first name. Surnames can also be used as middle names.
You can change your own name and the names of children under 16 for whom you have parental responsibility.
It takes approximately three weeks to process an application to change a name. You may easily log in and check in Altinn to see if your new name is registered. Your registered name in the National Registry will always appear under "Your contact information".
When we've approved your application, we'll send a letter to your address as registered in the National Registry. If the application is rejected, e-users will receive a message electronically. Others will receive a letter at the address they have registered in the National Registry.
The County Governor in the county in which you reside is the correct appeal body. You must still send the appeal via the tax office.
Under the age of 16?
If you're under 16, you need the consent of the person or persons who have parental responsibility for you. If the change of name concerns a child over the age of 12, the child must also give their consent.
Form on paper
Fill in the form Change of name (only in Norwegian - Melding om endring av navn) and send it to your local tax office.
Unrestricted and protected surnames
If more than 200 people in Norway share a surname, the surname is unrestricted.
As a rule, you're free to choose amongst unrestricted surnames. Using Statistics Norway's name search, you can check how many people have a particular surname.
A surname is considered to be protected if it's used by 200 people or less in Norway. To take a protected surname, everyone who already has that surname must give his or her consent.
You can also take a protected surname if you have an affiliation to the name, e.g. through kinship, marriage, a cohabiting partner who you have lived with for at least two years, or who you have children with, adoption, a relationship to step-parents or to foster parents. The case officer will contact you if documentation is required.
You can read more about surnames in chapter 2 of the Name Act(in Norwegian).
Do you want to take two surnames?
If you want to have two surnames, you must write the surnames separated by a hyphen. If you would prefer not to use a hyphen, you must choose one surname as a middle name.
Hyphenated double surnames
Example: Petter Hansen-Olsen. Here, Hansen-Olsen is the surname.
If you decide to have a double surname, you must always use the full name. You'll be listed in the telephone book under the first letter of your first surname. In this example, the person concerned would be listed under H.
Middle names and surnames
Example: Petter Hansen Olsen. Here, Hansen is the middle name and Olsen is the surname.
If you decide to have two surnames, where one is a middle name, there is no requirement to use the middle name. You'll be listed in the telephone book under the first letter of your surname. In this example, the person concerned would be listed under O.
How often can I change my name?
If you're over 16, you'll generally not be permitted to take, change or delete a first name or surname more than once every ten years. There are, however, exceptions.
If you have taken, changed or deleted a name, you can still do the following within the next ten years:
- Take the surname of a spouse or cohabiting partner who you have lived with for at least two years, or who you have children with
- Take a surname which you have had previously
- Take the surname of a step-parent, foster parent or adoptive parent
- Change your first name back to the first name you had before you changed it
- Take, change or omit a first name or surname if special reasons apply.
Abbreviations of names
Names are registered in full in the National Registry, but we have to abbreviate long names in extracts.
In cases where a surname, first name and middle name total more than 25 characters, the name will be abbreviated in official letters. The tax office will abbreviate the name according to fixed rules.
