Check a Norwegian company by API: Brønnøysund

Brønnøysund registers (Enhetsregisteret) · read from the national register · checked 11 November 2026

The official route

The Brønnøysund registers (Brønnøysundregistrene) serve an open API on data.brreg.no. We called the entity and accounts endpoints without a key on 2026-11-05. Roles are on the same open API.

• Entity by organisation number: https://data.brreg.no/enhetsregisteret/api/enheter/{orgnr}. Name search is enheter?navn=.
• Roles (CEO, board): the same path plus /roller.
• Accounts: https://data.brreg.no/regnskapsregisteret/regnskap/{orgnr}?regnskapstype=SELSKAP, key figures as JSON.

The open-data page on brreg.no says the datasets are under the Norwegian Licence for Open Government Data (NLOD) and that no registration is needed. NLOD allows commercial reuse with attribution. We found no published rate limit.

Where it gets hard

• The accounts API returns the last 3 fiscal years only, and only the register's key figures. There is no employee count and no gross profit.
• Those figures are the company's own accounts. For a parent company such as Equinor ASA that is the parent alone, without the group.
• The accounts API is not named on the open-data page, and Brønnøysund's GitHub README for it calls it a preview with "no guarantees of quality of service".
• Sole proprietorships (ENK) are in the same register, and their accounts are a natural person's.
• In what we read, a bankruptcy or winding up shows as the entity's status. We don't read a separate insolvency source for Norway.

One call

{"query": "Equinor ASA", "country": "NO"}

The endpoint is POST https://api.boscolabs.dev/v1/counterparty-check. The organisation number (923609016) works as the query too and is exact.

$0.05 per company checked, empty and failed calls are free.

What we do not cover

• VAT numbers: VIES does not cover Norway.
• Auditors and resigned or deregistered role holders are left out.
• Sole proprietorships are dropped from name search.
• Group figures exist only for listed companies, from their ESEF reports.
