Click on the subject below to open the dropdown for more information.

  • The Billing-Contact as well as the Owner-Contact need a local presence in Brazil. Therefore you can use our trustee service or provide us with your Brazilian register number (for the owner contact) and a Brazilian contact handle (for the billing contact).
  • Trustee service applied automatically, if domain owner contact isn't located in Brazil.
  • The registrant must be over 18 years old.

Successful domain registration via RCP or API requires:

  • If domain is being registered without trustee service:
    • Valid CPF number (Social security number) for private owner contact (CPF must be given in the following format: NNN.NNN.NNN-NN)
    • Valid CNPJ number (VAT number) for company owner contact (CNPJ must be given in the following format: NN.NNN.NNN/NNNN-NN)
  • Preconfigured DNS zone with at least 1 valid A-record. Zone can be verified via registry's DNS checker

NB: for registered domain names, their variations with additional ASCII characters are not possible. i.e. if domainname.com.br is registered, domain-name.com.br can't be registered. Such variations can be registered by the original domain owner only.

In case of a Brazilian contact the two letter state value is mandatory:

  • Acre - AC
  • Alagoas - AL
  • Amapá - AP

  • Domain owner completes a transfer application form
    • Completed form must be signed by domain owner and notarized

Owner change (trade)

  • Requested via RCP or API

Note: The registry has changed the process for modifying the contact of a .COM.BR domain from a real-time process to a non-real-time process that requires the new contact’s consent.

A contact update triggers an email to be sent to the new contact. It contains a link through which the request must be accepted. The link is valid for 24 hours, during this time the request remains in the PROCESSING status in the registry system. The contact change is only carried out after confirmation. If it is rejected or the link has expired, a new change request must be submitted.

The tech and billing contacts can also be changed by the domain’s administrative contact following the process outlined above.

Other update

  • Requested via RCP or API
  • Process can take several hours to take effect


  • A .com.br domain can only be deleted using NIC.BR online form, which is only available in Portuguese.

Registration agreement The registry requires that a registration agreement is in place between the provider and the domain holder. The text of this registration agreement and any required supplements is the following:

Due to the regular changes in registry rules and configuration or missing information from registry side, and despite our effort to keep our knowledge base up-to-date, information in the knowledge base may be outdated or incorrect. If you encounter some issue, please report it through the "HotJar" feedback collector on the bottom right, or (if it is blocked by your browser) by clicking the "Submit a request" link below. No rights can be derived from the information in this knowledge base. If there is discrepancy between the knowledge base and the process in Openprovider, the process in Openprovider is leading.
