This article describes the procedures and requirements of .rio domain names.
Click on the subject below to open the dropdown for more information.

Successful domain registration via RCP or API requires:

  • the owner contact to have an address in Rio de Janeiro (zip code format "12345-123")
  • tax payer ID (CNPJ or CPF) for the owner contact
  • two or more nameservers or a nameserver group
  • registrant e-mail address verification applies

A new registration is validated by the registry before it is activated. This validation process can take up to a few working days. As there are content requirements to the domain name (see 'Restrictions' in the detailed TLD information section below), the registry may re-validate the website now and then. If the registry finds that the domain is not meeting all requirements, they will contact the domain holder to cure the issues. Uncured issues may lead to suspended a suspension of the domain name. The domain can be unsuspended after the registrant solved the issue and responded to the registry.

Restricted and reserved domains
The Rio city government has composed a "reserved list". Domains on this list appear as unavailable in Openprovider, with reason "Policy restriction". Contact us if you want to register such a domain name. Generic terms will most likely be rejected, but requests for non-generic terms will be investigated by the city government. Please send us the following information if you want us to apply for a reserved domain name:

  • Domain name
  • Taxpayer ID of the prospective registrant
  • Name / Legal name of the prospective registrant
  • Physical address in Rio and a utility bill containing that address
  • Other similar domain names already owned by that registrant
  • Purpose of using that specific domain

There are no additional fees involved, though be prepared for a very slow process.

Successful domain transfer via RCP or API requires:

During the transfer period which can take 6 days, the current provider or the owner can reject to the transfer.

The registration period after a successful transfer will extend with 1 year, unless the transfer is ordered within the domain's auto-renew grace period at the previous registrar.
