How is a French VAT number built?
A French intra-EU VAT number is the FR prefix, a two-digit key and the SIREN, the 9-digit identifier INSEE gives every French company. The key is derived from the SIREN, so the number is always well formed.
What data do you get?
The tool returns the number and the company's status, each with its source.
| Field | Description | Source | Freshness |
|---|---|---|---|
| VAT number | FR + key + SIREN, computed | Computed from the SIREN | Instant |
| Company name | Registered name | INSEE SIRENE | Daily |
| Status | Active or closed, with closure date | INSEE SIRENE | Daily |
| Head-office town | Town and département | INSEE SIRENE | Daily |
What does it return on a real company?
A well-formed number can belong to a closed company, and the tool says so. For SIREN 552 100 554 (PEUGEOT SA) it computes FR96552100554, but SIRENE lists the company as ceased on 16 January 2021 (retrieved on 12 November 2026 from Reachable's public API). For SIREN 552 024 671 (CEGOS, Issy-les-Moulineaux) it computes FR09552024671 and the company is active.
What are the limits?
The number is computed, not verified: it does not prove the company is registered for VAT. Only the European Commission's VIES service confirms a number is active for intra-EU trade. Companies with restricted disclosure in SIRENE do not show their name. Result labels are in French.

Your AI assistant can drive the list through the MCP server. Source details are on the sources page; the price of a scheduled check is on the pricing page.
