List of municipality numbers of Norway

This is a list of municipality numbers used in Norway.

The numbers originate from 1946, when four-digit codes were assigned to each municipality. This also applied to municipalities which had ceased to exist at the time. Urban municipalities got municipality numbers in which the third digit was a zero. They were later applied in the ISO 3166-2:NO standard.

On 1 January 2018, the counties of Nord-Trøndelag and Sør-Trøndelag were merged into a new county called Trøndelag. This new arrangement meant that all municipalities would get new municipality numbers.
