How this service works
Norwegian company local units (underenheter, like SIRET establishments) from the official Enhetsregisteret (Brønnøysundregistrene, NLOD 2.0), refreshed daily from the national bulk: each unit's own 9-digit orgnr, name, industry code (NACE-NO) and auxiliary activity, published headcount, location and postal addresses, registration and ownership-change dates, VAT status, plus unit count and cumulative headcount. Legal persons only: a known one with no unit gets an explicit positive answer.
Output
A structured list of all local units (underenheter) associated with the queried Norwegian company, each containing: the unit's own 9-digit orgnr, name, NACE-NO primary industry code, auxiliary activity, published employee headcount, physical location and postal addresses, registration and ownership-change dates, VAT status, plus aggregate unit count and cumulative headcount. If the legal entity has no units but is a valid legal person, an explicit positive confirmation is returned. Unknown or sole-proprietorship numbers return 404 with no charge.
Example use cases
Supplier due diligence for Norwegian vendor
“I'm onboarding a Norwegian supplier with organisasjonsnummer 987654321 — can you fetch all their registered local units from the official Norwegian business registry, including addresses, industry codes, and VAT status?”
Market research on Norwegian company footprint
“I'm researching the physical presence of Norwegian company 923609016 — how many establishments do they have, where are they located, and what NACE industry codes are they registered under?”
Compliance check for Norwegian entity
“We need to verify whether the Norwegian legal entity 912345678 has any registered underenheter and confirm their VAT registration and headcount figures from the official Enhetsregisteret.”
Technical details
Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/NO/:id/etablissements?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official Norwegian establishment-level (underenhet) data for a legal entity, including NACE industry classification, addresses, VAT status, and headcount, sourced directly from Brønnøysundregistrene under NLOD 2.0. Prefer this over generic company databases when you need daily-refreshed, authoritative Norwegian government data for compliance, supplier onboarding, or market research. Note: sole proprietorships are not supported.
Side effects
- 404 returned for unknown organisasjonsnummer — payment cancelled
- 404 returned for sole proprietorship (enkeltpersonforetak) — payment cancelled, these are refused by design
- No units found returns explicit positive acknowledgement (known legal person with zero units), not an error
- Stale data possible within daily refresh cycle — data may lag up to 24 hours
- Invalid (non-9-digit or malformed) orgnr will likely return 404 or validation error
