How to Fix the “CPF Is Already in Use” Error for .br Domains

The “CPF is already in use” error occurs when the CPF (Cadastro de Pessoas Físicas) linked to your domain registration is already associated with another Registro.br account. This issue prevents you from registering or managing a .br domain under a new account.
