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