RDAP availability is taken from the IANA RDAP bootstrap file published on 2026-09-16; WHOIS server and delegation year from the IANA root zone database. Registry policies change: check the registry's own policy before relying on an eligibility rule.

What is .br?

.br is the country-code top-level domain of Brazil, operated by Registro.br, a department of NIC.br. Names are registered under category zones such as .com.br, .net.br or .org.br rather than directly under .br. Registro.br was an early adopter of RDAP and took part in its development.

Who can register it

Registrants are identified by a Brazilian tax number: a CPF for individuals or a CNPJ for companies. A foreign company needs a legal representative in Brazil to register.

WHOIS, RDAP and privacy

An RDAP service for .br (rdap.registro.br) is published in the IANA RDAP bootstrap file. OrbitProbe reads registration data from it first, as structured JSON: registrar, creation and expiry dates, EPP status codes and nameservers. For ccTLDs, what is published is decided by the registry and local law rather than by ICANN, so output differs from one extension to the next. Most registries do not show the personal data of individuals in public output. OrbitProbe only ever shows the organisation name and country.

How do I run a WHOIS lookup for a .br domain?

Type the name, in the form example.br, into the form on this page. OrbitProbe first queries the RDAP service of the .br registry (rdap.registro.br). The result shows where the data came from and when it was observed.

Does .br support RDAP?

Yes. The IANA RDAP bootstrap file dated 2026-09-16 publishes rdap.registro.br for .br. The classic WHOIS server is whois.registro.br.

Does .br support internationalised domain names (IDN)?

Yes, names containing non-ASCII characters can be registered under .br. Which characters are allowed is defined by the registry's IDN table. In the DNS such names are stored in Punycode form starting with "xn--"; OrbitProbe accepts either form.
