In all cases the registrant must have either a CPF or CNPJ, documents usually granted only to Brazilian residents or recognized companies Registrations at third level beneath various categories (but .com.br is still much more popular than others); Second-level registrations were allowed for institutions of higher education until 2000 https://registro.br yes 150px .br is the Internet country code top-level domain (ccTLD) for Brazil. It was administered by the Brazilian Internet Steering Committee until 2005 when it started being administered by Brazilian Network Information Center. A local contact is required for any registration. Registrations of domain names with Portuguese characters are also accepted. With the exception of universities, the second-level domain is fixed and selected from a list that defines the category. For example, .art.br is in the art (music, folklore etc.) category, and .org.br is in the non-governmental organization category. Institutions of tertiary education were allowed to use the ccSLD .edu.br, although some use .com.br and others (mainly public universities) use .br. There are also some other few exceptions that were allowed to use the second level domain until the end of 2000. As of April 2010, most domain registrations ignore categories and register in the .com.br domain, which has over 90% of all registered domains. The .jus.br (Judiciary), and .b.br (banks) domains have mandatory DNSSEC use. History Created and delegated to Brazil in 1989IANA - Informações sobre a delegação do .br by Jon Postel,NIC.br - CGI.br comemora os 20 anos do ".br" initially the domain was operated manually by Registro.br and administered by the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP). Originally, only researchers and institutions to which they belonged had the interest and ability to adopt the new system and register domains under .br. At the time, networks prevalent in the Brazilian academic setting were the BITNET ("Because It's Time NETwork"), the HEPnet ("High Energy Physics Network") and the UUCP ("Unix-to-Unix Copy Program"). As such, even before Brazil officially connected to the Internet in 1991, the .br domain was used to identify the machines participating in networks already in use by academics. In 1995 the Brazilian Internet Steering Committee (pt Comitê Gestor da Internet no Brasil, or simply CGI.br) was created with an objective to coordinate the allocation of Internet addresses (IPs) and the registration of .br domain names. There were 851 domains registered with the Brazilian DNS by the beginning of 1996, thereafter experiencing rapid growth with the mass arrival of companies, Internet providers and media onto the Internet. The registration system was automated in 1997 and was developed using open source software. In 2005, CGI.br created its own executive arm, the Brazilian Network Information Center (pt Núcleo de Informação e Coordenação do Ponto BR, or simply NIC.br),https://www.cgi.br/noticia/notas/comunicado-ao-publico/ Comunicado ao Público CGI.br 14 February 2006 18 August 2021 which currently serves in both administrative and operational capacity for the registry. In 2017, accounts associated with DNS records of Brazilian banks were hacked. Kaspersky's researchers pointed out to a vulnerability in NIC.br's website and suggested its infrastructure had been compromised. NIC's director at the time, Frederico Neves, denied that NIC.br was "hacked", although NIC.br admitted the vulnerability.https://www.wired.com/2017/04/hackers-hijacked-banks-entire-online-operation/ How Hackers Hijacked a Bank's Entire Online Operation Wired Andy Greenberg 4 April 2017 Kaspersky believes the attackers compromised NIC.br (...) Kaspersky points to a January blog post from NIC.br that admitted to a vulnerability in its website (...) [Frederico Neves] denied that NIC.br had been "hacked." But he conceded that accounts may have been altered Domain registry To register any domains under .br, it is necessary to enter into contact with Registro.br. Entities legally established in Brazil as a company ("pessoa jurídica") or a physical person ("profissional liberal" and "pessoas físicas") that has a contact within Brazil can register domains.Why Choose a .BR Domain for Your Business in Brazil? https://www.nominus.com/en/dm/blog/country-domains/august-2021/why-register-a-br-domain-in-brazil www.nominus.com en Foreign companies that have a power-of-attorney legally established in Brazil can also do it by following specific rules. The registration of domains including non-ASCII Portuguese characters (à, á, â, ã, é, ê, í, ó, ô, õ, ú, ü and ç) is accepted since 2005.Registro.br - Tips and Rules Syntactic rules for .br domains Minimum of 2 and maximum of 26 characters, not including the category. For example, in the field XXXX.COM.BR, this limitation relates to the XXXX. Valid characters are [A-Z, 0-9], the hyphen, and the following accented characters: à, á, â, ã, é, ê, í, ó, ô, õ, ú, ü, ç. Domains cannot contain only numbers. To maintain the integrity of the registry, Registro.br sets up an equivalence mapping to compare domain names with and without accented characters. The mapping is done by converting accented characters and the cedilla for their non-accented versions and "c", respectively, and discards hyphens. A new domain will only be allowed to be registered when there is no equivalent to a pre-existing domain, or when the applicant is the same entity that owns the domain equivalent. Specifically for the domain .NOM.BR, it is necessary to choose two names, i.e.: NAME1.NAME2.NOM.BR. Second-level domains Direct registration In 1991, it was decided that universities and research institutes would be allowed second-level .br domains directly. For example: Federal University of Rio de Janeiro got ufrj.br; University of São Paulo got usp.br; National Institute for Space Research got inpe.br; and so on.https://www.cgi.br/publicacao/nomes-de-dominio-na-internet/ Nomes de domínio na internet pt-br Demi Getschko CGI.br Pesquisa sobre o uso das tecnologias da informação e da comunicação 2005 São Paulo 21–24 1 April 2006 18 August 2021 In late 2000, the Brazilian Internet Steering Committee reported abuse in this system, and called for all institutions directly under .br to be moved to .edu.br – so, for example, ufrj.br would become ufrj.edu.br. During a meeting in early 2001, however, the Committee decided it would be of public interest to not move every second-level domain as to avoid confusion, but instead established rules regarding their registration:https://www.nic.br/registro-nota-edu/ Nota de Esclarecimento sobre utilização do DPN .edu pt-br NIC.br 18 August 2021 No longer accepting automatic registration of second-level domains, and evaluating every request for one individually; Creating edu.br, and forwarding requests from education and research institutions to it; Concession to education and research institutes that already had a second-level .br domain, as long as its usage is appropriate and that domain name is related to the institution's name or acronym. Domains approved are automatically duplicated under edu.br as well, and both may exist concurrently – for example, the still existing ufrj.br also has a registered ufrj.edu.br, although the latter is not used; Other institutions not approved above must be migrated permanently to edu.br (but would be given sufficient time for the transition). As of September 2024, Registro.br reports 1207 domains registered directly under .br. Predefined domains As of August 2025, there are 147 different second-level domains of .br under which custom domains can be registered, and they are divided into eleven categories: "Generic", "Business", "Culture", "Education", "Personals", "Entertainment", "Public Authority", "Locations", "Professions", "Technology" and "Third Sector".https://registro.br/dominio/categorias/ Categorias .br pt-br .br Categories Registro.br 20 August 2025 They are the following: "Generic" second-level .br domains Domain Intended use COM.br Commercial activities NET.br Commercial activities SOCIAL.br Social networks XYZ.br Miscellaneous WIKI.br Wiki-like pages ETC.br Companies that do not fit into other categories "Culture" second-level .br domains Domain Intended use ART.br Arts: music, painting, folklore REC.br Recreational activities, games TV.br Broadcasting companies or "transmission of sounds and images via the Internet" AM.br Radio companies FM.br Radio companies RADIO.br "Companies wishing to transmit audio through the network" "Business" second-level .br domains Domain Intended use ECO.br Eco- or environment focused activities LOG.br Transport and logistics EMP.br Small and micro-enterprises LEILAO.br AuctioneersRequires authorization by the Federação das Juntas Comerciais (Federation of Commercial Registries).
