Sirenic
GET https://api.sirenic.eu/v1/entreprise/:siren/etablissements
All establishments (SIRET) of a French company: the complete list of business locations registered under one SIREN, official data from the French company registry (INSEE Sirene), head office and branches alike, each with its address and open or closed status. Use it to map the branches and addresses of a company across France, or to check whether a given SIRET is still open. The SIREN identifies the legal entity; the SIRET identifies each of its establishments.
