CNPJ Generator and Validator
According to the CNPJ algorithm, its validation process consists of the calculation base of its last two digits, known as verifying digits, which indicate the authenticity of the other digits that make up the CNPJ number. Therefore, when a number is declared valid by this validator, it means that it is in compliance with the result expected by the CNPJ algorithm. However, it does not suggest the existence or regular cadastral situation. To check this, please visit the official website of the Federal Revenue of Brazil at this link, inform the CNPJ and then click on the 'Consultar' button to check the CNPJ registration status.
