Troubleshooting Tips #

1. CPF Not Eligible:
   • For business registrations, use a CNPJ (Cadastro Nacional da Pessoa Jurídica) instead.
   • Verify if your CPF holder is authorized for the domain extension (e.g., individuals cannot register certain extensions like .gov.br).
2. Delayed Validation:
   • CPF validation can take time if submitted for verification. Check your email for updates from Registro.br.
3. Use an Accredited Registrar:
   • Ensure you are registering the domain through an official or accredited registrar to minimize errors.
