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 .com.br?

.com.br is the general commercial zone under .br and by far the most used Brazilian extension. It is a category zone operated by Registro.br inside .br, listed on the Public Suffix List, so example.com.br is a registrable domain.

Who can register it

Open to both individuals and companies, but the registrant must hold a Brazilian CPF or CNPJ. Foreign companies register through a legal representative established in Brazil.

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 .com.br domain?

Type the name, in the form example.com.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 .com.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.

Is .com.br a top-level domain?

No. The top-level domain is .br; .com.br is a second-level zone the registry operates beneath it. Because it is on the Public Suffix List, tools and browsers treat example.com.br as the registrable domain. WHOIS and RDAP data come from the .br registry.
