.br Domain Registration
Not every .br domain can be registered by anyone: some categories are open, and others require proof of a regulated profession. This page explains the difference between them, the document each one asks for, and what happens to a domain when its registration is not renewed, before you look one up in the tool.
The registro.br domain itself shows as exempt from the normal renewal rules, since it belongs to the entity that administers the .br TLD.
No registration found for that label, so it is free for any CPF or CNPJ to register under the com.br category.
Registro.br caps a label (the part before .com.br) at 26 characters, so longer names are rejected before availability is even checked.
Yes. This kind of lookup usually tells you whether a domain appears available, taken or under another status, and it may also provide similar alternatives when the desired name is not free.
Not for the open categories: a CPF alone is enough to register com.br, net.br, org.br, and other generic categories; a CNPJ only becomes a requirement for categories specifically tied to companies.
com.br is a generic category open to any CPF or CNPJ, while adv.br is restricted to lawyers, requiring the holder's CPF and an active OAB registration that Registro.br verifies before releasing the name.
The label before .com.br (or another category) is capped at 26 characters, on top of other format rules; longer names or ones with disallowed characters are rejected as UNAVAILABLE before availability is even checked.
The domain is cancelled at the end of its 12-month cycle if payment isn't made, and it enters a public release process where other people can apply for the name; the previous holder has no guarantee of automatically getting it back afterward.
Check whether a .br domain is available, its name servers and expiry date.
Enter the domain without http, for example example.com.br.
