About this Generator
This tool generates valid Argentine CUIT numbers that comply with the official format and validation rules set by AFIP.
The generator creates CUITs following the official structure and includes proper entity type prefixes and valid check digits.
Generated CUITs are for testing purposes only. While they follow the correct format and pass validation checks, they are not officially registered numbers.
