matrikkelnummer

Matrikkelnummer is the unique numeric identifier used in Norway to identify a parcel of land or property in the national cadastral register known as Matrikkelen. It is assigned to a land parcel when it is registered or subdivided and serves as a stable reference for the property within the country.

The primary purpose of the matrikkelnummer is to support land registration, property transactions, taxation, planning, and other public administration tasks. It provides a canonical reference for the exact location and boundaries of a property, and it is used in official documents, cadastral maps, and legal proceedings. The number remains associated with the parcel even if ownership changes.

In practice, Norwegian properties are also described locally by gårdsnummer (gnr) and bruksnummer (bnr), which designate farm and unit numbers within a municipality. The matrikkelnummer uniquely identifies the parcel nationwide, while gnr/bnr are often used for descriptive and administrative purposes in local contexts. The two systems are complementary, with matrikkelnummer serving as the nationwide anchor for property identification.

The Matrikkel is maintained by the Norwegian Mapping Authority (Kartverket) in collaboration with municipal cadastre offices. Property information, including matrikkelnummer, is publicly accessible through Kartverket’s services and other official channels, subject to applicable privacy and licensing rules. Access to the data enables verification of property boundaries, ownership history, and related land-use information, and it supports accurate public records and transactions.
