About this API
Enhetsregisteret is the Norwegian equivalent of REGON — the central registry of all businesses and organisations in Norway, run by the Brønnøysund Register Centre (Brønnøysundregistrene). Every entity has a nine-digit organisation number (organisasjonsnummer) that the API uses to return full registry data. Entities can also be searched by name.
Frequently asked questions
Do I need an API key?
No, the API is fully public and free — no registration, no key required.
What data does this API return?
Registry data for a Norwegian entity by organisation number — name, legal form, address, industry codes (NACE), status and registration date. Entities can also be searched by name.
Can this API be called directly from a browser?
Yes — the API returns a CORS header allowing calls from any domain, so it works directly from frontend code (hence the live "Try it" button above).
Who runs this API?
Brønnøysundregistrene (the Norwegian Register Centre). Full documentation is available at data.brreg.no.
