About this Validator
This tool validates Brazilian Individual Taxpayer Registry numbers (CPF - Cadastro de Pessoas Físicas) according to the official format requirements.
The validator checks if a given CPF follows the correct structure and verifies the two check digits using the official algorithm.
This validation only confirms if a CPF follows the correct format. It does not verify if the number is actually registered with Brazilian authorities.
