CPF Validator

The CPF Validator is an online tool that checks if a CPF number (Cadastro de Pessoas Físicas) is mathematically valid, according to the verification digit calculation algorithm defined by the Brazilian Federal Revenue.

This tool is ideal for developers, testers (QAs), and students who need to verify CPF validation logic in their systems. A CPF validated here will pass format checks, but it is crucial to understand that this does not mean the CPF exists or belongs to a real person.
