Postcodes – updated postcode tables and useful information about postcodes and addresses

It is important to use the correct postcode so that mail is not delayed or returned.

The postcode register

The postcode tables contain all postcodes that are used for addressing mail in Norway. Here you will find an overview of new, changed or discontinued postcodes. The files also contain municipal numbers and names. Please note that some postcodes may extend over more than one municipality. In such cases, the municipality with the highest number of mail recipients will generally be selected. The county number is the two first digits in the municipal number, and you will find a list of counties, among other things, in the guide.

The postcode tables are valid from 2025/10/01:
