About the Alphanumeric CNPJ Validator
This tool validates the new alphanumeric CNPJ format established by IN RFB No. 2,119/2022. Starting July 2026, the Federal Revenue may issue CNPJs containing letters (A-Z) and numbers (0-9), increasing combination possibilities.
The verification digit calculation algorithm is similar to the traditional CNPJ, but adapted to work with alphanumeric characters. This tool is essential for testing your system's compatibility with the new standard.
