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.
