French SIREN Validator

Verify French SIREN numbers and matching company records.

French SIREN Validator checks the format and local checksum of every 9-digit French business identifier entered in your form. When registry confirmation is enabled, it also looks up the legal unit, confirms the company name, and can flag closed businesses. Clear validation feedback helps onboarding, procurement, registration, and compliance workflows collect cleaner company data before submission.
