Request body

compliance_identifiersobject nullable

The company's official French registration numbers, given as key/value pairs where each key names a type of identifier and the value is the number itself. You do not need to send all three — always include FR_SIREN, and add the others only if they apply:

  • FR_SIREN — required. The 9-digit number that identifies the company nationally.
  • FR_SIRET — optional. The 14-digit number that identifies one specific site of the company (its SIREN followed by a 5-digit site code). Include it when registering a particular establishment.
  • FR_VAT — optional. The company's French VAT number. It is derived from the SIREN/SIRET, so you normally don't need to set it yourself.
