About this Generator

This tool generates valid French National Registration Numbers that comply with INSEE specifications.

The generator creates NIRs following the official structure, including valid dates, locations, and check digits.

Generated NIRs are for testing purposes only. While they follow the correct format and pass validation checks, they are not officially registered numbers.
