How this service works
Official Belgian company registry lookup (KBO/BCE, Banque-Carrefour des Entreprises / Kruispuntbank van Ondernemingen). Query: /v1/eu/entreprise/BE/0403199702 (10-digit number, dots optional). Returns legal name, legal form, normalized status, incorporation date, registered office, NACEBEL activities (French labels), establishment units, VAT, LEI and register link. Legal persons only: an entity without legal form or of a form without legal personality returns 404, not billed.
Output
Returns a structured object with the company's legal name, legal form, normalized status (e.g. active/inactive), incorporation date, registered office address, NACEBEL activity codes with French labels, a list of establishment units, VAT number, LEI code, and a direct link to the official KBO/BCE register entry.
Example use cases
Supplier KYC before onboarding
“Before we onboard this Belgian supplier, can you check their official KBO/BCE details for enterprise number 0449.321.728 — I need their legal name, current status, and registered office address?”
Verify Belgian company VAT number
“I need to verify the VAT number and legal form for Belgian company 0403170701 from the official register before processing their invoice.”
Due diligence on Belgian business partner
“We're considering a partnership with a Belgian company whose enterprise number is 0672.400.155 — can you fetch their incorporation date, legal status, NACEBEL activities, and LEI from the KBO/BCE register?”

Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/BE/:id?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need official Belgian company data from the KBO/BCE register, including legal form, NACEBEL sector codes, establishment units, VAT number, or LEI. Prefer this over generic EU company search when you already have the Belgian enterprise number and need authoritative, daily-refreshed government data for compliance, KYC, or supplier verification purposes.
Side effects
- Invalid or malformed enterprise number (not 10 digits, contains dots/spaces) — returns 400 or validation error
- Enterprise number not found in KBO/BCE — returns 404
- KBO/BCE data source temporarily unavailable — returns 503
- Number format includes dots or spaces instead of plain digits — rejected by path parameter validation
