What is Brønnøysundregistrene? Norway's company register

Brønnøysundregistrene is the Norwegian agency operating the country's central registers. The one that matters for company verification is Enhetsregisteret, the Central Coordinating Register for Legal Entities, holding every registered organisation in Norway. It is published as free open data with no registration, which is why Norwegian coverage tends to be more complete and fresher than most European registries.

The organisation number

Every entity gets a 9-digit organisasjonsnummer carrying a modulo-11 checksum, so malformed numbers can be rejected offline. Numbers in issue run from roughly 810 million upward. Prometiam serves the raw organisation number as the Norwegian company id, so it round-trips to Brreg directly.

What the register publishes

Name and former names, organisation form (AS, ASA, ENK, NUF and others), registered and business address, NACE-aligned industry code, bankruptcy and liquidation status flags with dates, and roles including directors, chair, CEO and auditor. A NUF is a Norwegian branch of a foreign company — it has an organisation number, but the legal entity sits in another jurisdiction.

One real limitation

Norway has no corporate-event gazette comparable to BORME or BODACC, so there is no appointment/capital/merger stream to ingest and corporate-event endpoints return nothing for Norway. Norwegian corporate insolvency notices are served separately.

Frequently asked questions

What is Bronnoysundregistrene?
The Bronnoysund Register Centre is the Norwegian government agency operating the country's central registers. Enhetsregisteret, the Central Coordinating Register for Legal Entities, holds every registered organisation in Norway and is published as free open data with no registration required.
What is a Norwegian organisation number?
A 9-digit organisasjonsnummer issued to every registered entity, carrying a modulo-11 checksum so malformed numbers can be rejected offline. Numbers in issue run from roughly 810 million upward.
What is a NUF?
A Norwegian-registered branch of a foreign company. It has an organisation number and appears in Enhetsregisteret, but the legal entity behind it is in another jurisdiction, so a NUF match is not by itself evidence of a Norwegian counterparty.
Does Prometiam serve Norwegian corporate events?
No. Norway publishes no corporate-event gazette equivalent to Spain's BORME or France's BODACC, so there is no event stream to ingest and company-event endpoints return nothing for Norway. Norwegian companies, officers and corporate insolvency notices are served.
