According to the .BR Domain Authority:
Registration
Any entity legally established in Brazil as a corporate entity or individual that counts with a contract in national territory can register a .br domain name. Also, foreign businesses that count with an attorney legally established in Brazil.
Note that .br domain name reservations cannot be made; these are exclusive prerogatives of the Domain Authority.
Domain’s name modification does not exist either. You must request the cancellation of the domain that you do not want and request the registration of the new domain.
It is important to know that if some party registers a domain in any particular category, another entity can register the same domain in another category.
It is not allowed to transfer domains between “Individuals” and “Corporate Entities” categories and vice versa. The only exceptions are domains .com.br, which may be registered by individuals or corporate entities.
Domain contacts
There are 4 contacts: entity contact, administrative contact, technical contact and payment contact.
The entity contact is responsible for the maintenance and update of the entity’s information, registration of new domains and transfer of contacts from domains held by the same. The administrative contact may alter information of DNS servers and transfer technical and payment contacts. The technical contact can modify DNS servers. The payment contact aims to provide the email address where to send the invoice. (*If the entity and domains are not managed by a Service Provider).
Syntax
The characters that can be accentuated are all vowels and the cedilla (ç), according to the Portuguese Language rules:
à, á, â, ã, é, ê, í, ó, ô, õ, ú, ü, ç
There are two situations in which it would be advisable to register accentuated domains: first, in cases where the absence of accent alters the meaning or gives the domain a pejorative connotation. And second: you may register domains with and without accent and redirect them towards a unique address, in order to attract the target audience. Many businesses register domains with and without hyphen with the same aim. Meanwhile, no business is obliged or driven to register both versions of the domain, since the registration of one of them ensures that no other entity can register the other version.
If you register a domain without accentuation and/or cedilla (ç), the system will not convert it automatically to accentuated version. The user that wants to use a domain with accent and/or cedilla (ç) should register it.
A domain with accent and/or cedilla (ç) can be registered only by the same entity that owns the equivalent domain without accent and/or cedilla (ç).
If the domain is registered with accent and/or cedilla (ç) the email address will also present the accentuated domain. The accentuation possibility in a username (ex: josé@xxxx.com.br) must be verified with the email server administrator.
