About this Generator
This tool generates valid French Company Identification Numbers that comply with official format requirements.
The generator creates SIRENs following the official structure, including valid sequential numbers and Luhn check digits.
Generated SIRENs are for testing purposes only. While they follow the correct format and pass validation checks, they are not officially registered numbers.
