What it is

Brreg is Norway's central registry for businesses and organizations. Every legal entity registered in Norway — AS, ASA, ENK, NUF, foundations, municipalities, associations — has a record here, keyed by a 9-digit organization number.

Orakel ingests the full dataset and tracks changes through the Brreg updates feed. Every 15 minutes Orakel pulls new changes and upserts the affected records; once a month a full snapshot re-seeds the database to catch anything the feed missed.

Endpoints that surface this data

GET /api/companies — search companies; returns Brreg firmographics plus embedded financials and active roles
GET /api/companies/:orgNumber — full company record. Norwegian companies not yet in the database are fetched from Brreg on the fly and cached
GET /api/companies/:orgNumber/group — corporate-group tree built from parentOrgNumber
GET /api/updates?since=<ISO date> — cursor-paginated feed of companies whose record changed after the given timestamp. Backed by Brreg's own updates feed.

Limitations

Brreg itself covers firmographics and roles. Financial statements live in regnskapsregisteret; shareholder data lives in aksjonaerregisteret.
Registered website is self-reported at registration and is frequently stale. Orakel runs a separate domain-enrichment pipeline (primaryDomain, enrichedDomains) to produce a verified domain.
Employee counts for the parent Company do not include sub-unit headcounts — aggregate across subUnits[] if you need a total.

Gotchas

The 15-minute diff sync can lag the public Brreg UI by a few minutes. For a guaranteed-fresh record, pass ?country=NO to GET /api/companies/:orgNumber — on a database miss Orakel fetches live from Brreg.
Dissolved and bankrupt companies are retained. dissolvedAt may be set while the record still appears in search results; filter on isBankrupt or isBeingDissolved if you want to exclude them.
orgNumber is globally unique within Norway, but across the Nordic registries Orakel stores records under (country, orgNumber). Always pass country explicitly when querying a specific record from a multi-country client.
Brreg stores auditors as entity roles (entityOrgNumber populated) rather than as person roles. Board roles are per-person.
