About this API

Sirene is France's equivalent of REGON/CEIDG — a registry of every business (SIREN) and establishment (SIRET) in France, run by INSEE (France's statistical office) since 1973. The API lets you look up entities individually by SIREN/SIRET number, by name, or with multi-criteria queries.

Frequently asked questions

Do I need an API key?

Yes — you need to create a free account at portail-api.insee.fr and authenticate requests via OAuth2. A limit of 30 requests per minute applies.

What data does this API return?

Registry data for French businesses and their establishments — name, legal form, address, creation date, status (active/closed), and change history — from a SIREN or SIRET number.

Can this API be called directly from a browser?

Not easily — OAuth2 authentication requires exchanging credentials for a token server-side, which doesn't lend itself to a direct call from frontend code visible to a visitor.

Who runs this API?

INSEE (Institut national de la statistique et des études économiques), France's statistical office. Full documentation is available at portail-api.insee.fr.
