The short version

Brønnøysundregistrene (the Brønnøysund Register Centre, often shortened to Brreg) is the Norwegian government agency that operates the country's central registers. The one that matters for company verification is Enhetsregisteret, the Central Coordinating Register for Legal Entities, which holds every registered organisation in Norway — companies, sole proprietorships, associations, foundations and public bodies alike.

Norway is unusually open here. Enhetsregisteret 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. It carries a modulo-11 checksum, so a malformed number can be rejected before you spend a lookup. Numbers currently in issue run from roughly 810 million upward, which is a useful sanity check — a 9-digit Norwegian number starting with a low digit is almost certainly not an organisation number.

Because it is a public identifier that round-trips to Brreg, Prometiam serves the raw organisation number as the company id for Norway rather than an internal surrogate. If you hold a Norwegian org number already, you can query with it directly.

What Enhetsregisteret publishes

FieldNotes
Name and organisation numberPlus any previous names.
Organisation formAS (private limited), ASA (public limited), ENK (sole proprietorship), NUF (Norwegian branch of a foreign company), and others.
Registered and business addressIncluding municipality code.
Industry codeNACE-aligned.
Status flagsBankruptcy, liquidation and forced-liquidation flags, with dates.
RolesDirectors, chair, CEO and auditor, from the roles register.

NUF deserves a note: a NUF is a Norwegian-registered branch of a foreign company, not a Norwegian company. It has an organisation number and appears in the register, but the legal entity behind it sits in another jurisdiction — so a NUF hit is not by itself evidence of a Norwegian counterparty.

One real limitation

Norway has no corporate-event gazette comparable to Spain's BORME or France's BODACC. There is no published stream of appointment changes, capital changes and mergers to draw on, so corporate-event endpoints return register-change events only (name, status, legal form, registered address), none before 14 Oct 2026. Company and officer data are current.

Norwegian bankruptcy is covered separately — Prometiam carries Norwegian corporate insolvency notices alongside France, Finland, Germany, the UK, Austria, Switzerland, the US and the Netherlands.

Querying Norwegian companies from an API

Prometiam serves Norwegian companies and officers from Enhetsregisteret alongside every other registry the API covers, under one schema and one key. Annual accounts as filed (the last three approved accounts) are served from the Scale plan. The Norway company data API guide shows the organisasjonsnummer lookup with roles and insolvency notices.

Norwegian company ids are the organisation number itself, so the id you get back is the id Brreg uses.

FAQ

How do I search for a Norwegian company by organisation number?
Type the nine-digit organisasjonsnummer or the company name into the free organisation number lookup to see name, legal form, status and municipality from Enhetsregisteret. The same lookup is available in the API as GET /companies/search?country=NO.

What is an organisasjonsnummer?
Norway's 9-digit organisation number, issued to every registered entity and carrying a modulo-11 checksum you can validate offline.

Is Norwegian company data free?
Enhetsregisteret is published as open data without registration, which is why Norwegian coverage is unusually complete.

What is a NUF?
A Norwegian-registered branch of a foreign company. It has an organisation number but the legal entity sits in another jurisdiction.

Does Prometiam serve Norwegian corporate events?
Only register changes (name, status, legal form, registered address), none before 14 Oct 2026: Norway publishes no corporate-event gazette equivalent to BORME or BODACC. Companies, officers and insolvency notices are served.
