Domain Registration

domain               =
period               = 1....10

Please Note
There is a parameter which is mandatory for the registration of a .BR domain without trustee service:

The CPF is the financial identity number provided by the Brazilian Government for every Brazilian citizen in order to charge taxes and financial matters. The CNPJ is the same as the CPF but it works for companies.

  • The CPF must be given in the following format: NNN.NNN.NNN-NN
  • The CNPJ must be given in the following format: NN.NNN.NNN/NNNN-NN

Please note:

  • If you register the domain without trustee service then you have to state a billing contact with a valid Brazilian address.

Trustee Service

If there is no eligible contact available you can use our Trustee Service which offers such a contact. To use the optional service you can submit the following extension:


command                 = adddomain
domain                  =
period                  = 1....10


  • After the domain's registration, our system could have add a further extension to your domain. This will happen, if a concurrent application is active at the registry. The extension is X-BR-CONCURRENT-APPLICATION. It's value is 1. The extension is read-only and not available by API.
  • The validation process by the trustee can take between one and three days
  • The trustee service is NOT available for ORG.BR domain names
