SIREN / SIRET
Official identifiers of French companies: SIREN designates the legal entity, SIRET a specific establishment.
SIREN is a 9-digit number that uniquely identifies a company. SIRET (14 digits) adds a specific establishment code: one company has one SIREN and as many SIRETs as it has establishments.
These identifiers are the most reliable key to match company data unambiguously: unlike a trade name, a SIREN has no namesakes. They are indispensable to French firmographics.
