Pix Key Validator
Validate Brazilian Pix keys of any type: CPF, CNPJ, email, phone (+55) or random UUID. Detects the type automatically.
What are the Pix key types?
Pix supports 5 key types: CPF (11 digits), CNPJ (14 digits), email, phone with country code (+55) and random key in UUID v4 format. This tool detects the type from the format and validates the checksum where applicable.
For CPF and CNPJ, we validate the check digits by modulo 11. For email and phone, we validate the format. For random keys, we validate the UUID pattern. The tool does not query the Pix registry — it only validates the structure.
100% local validation. No key is transmitted.
