What Is the .br Domain? Brazil's Country-Code TLD Explained

The .br domain is Brazil's official country-code top-level domain (ccTLD), and one of the largest ccTLDs in the world by registration volume. Every .br registration — whether under the dominant .com.br category or a direct second-level name — requires a valid Brazilian tax ID: a CPF for individuals or a CNPJ for companies. This page covers what .br is, who runs it, exactly who is eligible (including the documented path for foreign companies), and the honest trade-offs on pricing, SEO, and reputation.

.br at a glance

What is .br?

.br is the ccTLD assigned to Brazil under the ISO 3166-1 country-code system used by IANA. Like other ccTLDs, it has no ICANN Registry Agreement — the governing rules come from Brazil's own internet-governance structure instead. Policy authority sits with the Comitê Gestor da Internet no Brasil (CGI.br), the multistakeholder Brazilian Internet Steering Committee; its executive arm, Núcleo de Informação e Coordenação do Ponto BR (NIC.br), handles both administrative and operational duties, and its Registro.br department is the operational registry that IANA lists as the ccTLD manager.

Because .br functions as a genuine national namespace, Google treats it as country-targeted rather than generic — it does not appear on Google Search Central's short list of ccTLDs treated as generic, unlike vanity extensions such as .tv or .me.

History of .br

• 1989 — Delegation. .br was delegated to Brazil in 1989, one of the earlier ccTLD delegations globally.
• 1995 — CGI.br formed. The Brazilian Internet Steering Committee began managing .br policy.
• 1991–2000 — Early direct registrations. Universities and research institutions could register directly under .br from 1991, but reported abuse of that open pattern led the committee to restrict and individually evaluate direct requests starting in 2001.
• 2005 — NIC.br established. CGI.br created NIC.br to formalize administrative and operational capacity, with Registro.br running day-to-day registry operations.
• Category system matures. Over time the registry grew to roughly 147 defined second-level categories across groups such as generic, business, culture, education, professions, technology, and public authority — with .com.br becoming by far the dominant choice.
• Today. Registro.br's own live statistics show the .br namespace has grown to roughly 5.8 million total registered domains, with the generic category (led overwhelmingly by .com.br) accounting for over 98% of that group.

How people use .br

• Brazilian businesses of every size, almost all defaulting to .com.br as the standard commercial address.
• Professionals and freelancers, who can register under CPF-eligible generic or professional categories.
• Non-profits and civil-society organizations, using categories such as .org.br.
• Educational and research institutions, historically among the first direct .br registrants.
• Foreign companies establishing a Brazilian footprint, via the documented legal-representative registration path.

Who it's not ideal for: individuals or companies with no Brazilian tax ID and no intention of appointing a legal representative in Brazil — the CPF/CNPJ gate makes casual, presence-free registration impossible — and global-first brands where a Brazil-specific geo signal is unwanted.

Notable sites using .br

.com.br is so dominant within the Brazilian web that it functions as the de facto local equivalent of .com: Registro.br's own statistics put the generic category (almost entirely .com.br) at over 98% of all registrations in that group, out of roughly 5.8 million total .br domains. In practice, the large majority of Brazil's major banks, retailers, and media outlets hold their primary web presence on .com.br rather than a direct .br or .com address — a structural fact more durable and verifiable than naming any single brand.

.br vs other domains

Pick .com for a global, non-geographic brand; pick .br (almost always as .com.br) when your business is genuinely Brazilian and you hold a CPF or CNPJ; compare against .mx if you're weighing another major Latin American ccTLD with a similar category-plus-direct structure but a notably more open eligibility policy.

Why choose .br?

• Deep local trust — .com.br is the default, expected address for a Brazilian business, ahead of .com in local perception.
• Verified registrant base — the CPF/CNPJ requirement keeps the namespace tied to real, tax-registered individuals and entities.
• Native Portuguese support — full support for Portuguese accented characters in domain names.
• Large, active namespace — one of the largest ccTLDs globally by registration count, evidence of deep, sustained real-world adoption.

Things to consider

• Tax-ID gate. A CPF or CNPJ is mandatory; there is no route to register without a valid Brazilian tax identifier or a documented legal representative.
• Foreign-registration paperwork. Non-Brazilian companies must appoint a Brazil-based attorney/representative and submit notarized, consular-legalized, Portuguese-translated documentation — a meaningfully heavier process than most open gTLDs.
• Category sprawl. With roughly 147 second-level categories, choosing the right one can be confusing, though .com.br covers the vast majority of cases.
• Geo-targeted, not global. The Brazil-specific SEO signal that builds local trust works against ranking for international, non-Brazil-specific search intent.

Who can register a .br domain?

Registration restrictions: gated by CPF/CNPJ tax ID. Under Registro.br's domain rules, individuals must provide a valid CPF (Cadastro de Pessoa Física) and legal entities a valid CNPJ (Cadastro Nacional de Pessoa Jurídica), both checked against Brazil's Federal Revenue Service. Some categories accept either ID; others (like .com.br) are effectively open to any CPF or CNPJ holder, while a handful of restricted categories require additional proof tied to the category's purpose.

Foreign companies can register without Brazilian incorporation, but only through a documented process set out on Registro.br's rules for foreign companies page: appointing a legally established representative (procurador) in Brazil, and submitting a notarized power of attorney plus a certified commercial-activity declaration and a declaration committing to establish permanent operations in Brazil within 12 months — all legalized at a Brazilian consulate and translated by a sworn translator. Registro.br then issues an identifier that substitutes for a CNPJ.

Domain names must be 2–26 characters (excluding category), support Portuguese accents, and cannot start/end with a hyphen or be all-digit. DNSSEC is supported; standard renewal rules apply through accredited registrars.

.br pricing and value

.br pricing dynamics follow the pattern typical of gated ccTLDs: first-year and renewal pricing can differ, so a lower entry rate is not necessarily what you'll pay long term — budget for renewal. Because eligibility is tied to a verified CPF/CNPJ rather than open bidding, .br lacks the large premium-name marketplace of unrestricted gTLDs; cost is driven mainly by category, string length, and registrar margin, with the foreign-company route carrying extra documentation overhead rather than a stated premium fee. We list no figures here; check current rates at the point of purchase.

Reputation and email deliverability

Because every .br registration requires a verified CPF or CNPJ (or the documented foreign-company process), the namespace has not developed the bulk-registration spam reputation seen on some wide-open new gTLDs. Mail providers generally treat .com.br and other .br categories no differently from other established ccTLDs — deliverability issues are typically about sender practices, not the extension itself, though correctly configuring SPF, DKIM, and DMARC remains standard practice.

Branding and naming tips

• Default to .com.br for commercial brands. It is the namespace Brazilian consumers actually expect and trust.
• Use Portuguese accented characters deliberately. IDN support lets a name read naturally in Portuguese, but confirm the unaccented equivalent isn't already taken by someone else — Registro.br treats accented and unaccented versions as related.
• Keep foreign-registration paperwork in mind early. If you're a non-Brazilian company, budget time for the notarized, consular-legalized documentation process before you need the domain live.
• Consider direct .br only deliberately. It exists and is shorter, but .com.br remains the namespace most Brazilian users recognize by default.

How to register a .br domain

1. Search for your desired .br or .com.br name to check availability.
2. Confirm eligibility — a valid CPF or CNPJ, or the documented foreign-company representative process.
3. Register and configure DNS to point your site or email.

Frequently asked questions

Can anyone register a .br domain?

No. Registro.br requires every registrant to hold a valid Brazilian tax ID — a CPF for individuals or a CNPJ for legal entities — verified against the Federal Revenue Service. Foreign companies can register only by appointing a legally established representative in Brazil and completing a documented registration process.

Does a .br domain affect SEO?

Yes. Google treats .br as a country-code TLD geo-targeted to Brazil, since it is not on Google's short list of ccTLDs treated as generic. That helps Brazil-focused sites rank for Brazilian searches and works against sites targeting a global audience.

What is the difference between .com.br and direct .br?

Both require the same CPF/CNPJ eligibility. .com.br is by far the dominant category, covering the large majority of all .br registrations. Direct second-level .br registration (yourname.br, without a category) also exists but remains a small fraction of the namespace by comparison.

Who runs the .br domain?

The Brazilian Internet Steering Committee (CGI.br) sets policy for .br. Its executive arm, the Brazilian Network Information Center (NIC.br), operates the registry through its Registro.br department, which IANA lists as the ccTLD manager.
