.br and .com.br requirements
A .br registration normally needs a Brazilian CPF or CNPJ and the correct category
Registro.br states that .br categories are available to individuals or organisations legally established or represented in Brazil with a regular CPF or CNPJ record. A foreign company can apply through a legal representative established in Brazil. Category-specific eligibility, documents and DNS requirements can also apply.
Who can register a .br domain?
Brazilian individual
The applicant normally needs a valid CPF and contact in Brazil.
Brazilian organisation
The organisation normally needs a regular CNPJ record and authorised contact.
Foreign company
Registro.br says a foreign company can apply through a legal representative established in Brazil using the foreign-registration procedure.
Accurate holder data
The holder, tax identity and contact information must be accurate and kept current.
Category eligibility
Some endings require the applicant’s activity, legal form or professional status to match the selected category.
Supporting evidence
Restricted categories and foreign-company applications can require documents or authorisation.
Which .br category should you choose?
| Example category | General purpose | Important check |
|---|---|---|
| .com.br | General commercial and widely used registration | Holder must meet the applicable CPF or CNPJ requirements |
| .net.br | Generic category available under current Registro.br categories | Do not assume it has the same role or customer recognition as .com.br |
| .blog.br and .nom.br | Personal publishing or personal-name uses | Check which holder type is eligible |
| Professional categories | Examples include categories for regulated or recognised professions | Professional eligibility can be checked |
| .org.br and education categories | Non-profit or education uses | Supporting documents and activity checks can be required |
| Government and regulated categories | Public bodies or regulated activities | Prior authorisation or registry review is normally required |
Registro.br maintains more than 100 categories. Check the official category list before choosing an ending.
Which characters can a .br name contain?
For the registrable label before the category, Registro.br publishes these main syntax rules:
Length and characters
Use 2 to 26 characters, excluding the category. Latin letters, digits, hyphens and specified Portuguese accented characters are accepted.
Position and content
The name cannot contain only numbers and cannot begin or end with a hyphen.
How do you prepare a .br registration?
- 1Choose the correct holder route
Confirm whether the applicant is a Brazilian individual, Brazilian organisation or foreign company using a Brazilian legal representative.
- 2Select the category
Choose
.com.bror another category that genuinely fits the holder and intended use. - 3Search and check rights
Confirm availability and review relevant business names, trade marks and existing equivalent spellings.
- 4Prepare identity details
Provide the correct CPF, CNPJ or foreign-company documentation and representative information.
- 5Prepare DNS
Confirm which authoritative nameservers will host the zone or whether the applicable Registro.br DNS option will be used.
- 6Review and respond
Check the term, renewal, VAT and category requirements, then answer any genuine registrar or registry request promptly.
Why does DNS matter during .br registration?
Registro.br requires at least two authoritative DNS servers for a delegated domain. Its registration system can provide registry DNS in many categories when private provider nameservers are not supplied, but restricted categories can differ.
Using provider nameservers
The nameservers should be configured authoritatively for the new domain. Registro.br can test the setup and allow a correction period when it is not ready.
Using registry DNS
This may allow registration before separate hosting DNS is prepared for eligible categories. Check how later DNS management and provider connection will work.
What should you manage after registration?
Holder and account contacts
Keep the CPF or CNPJ-linked holder and administrative contacts accurate. Some holder changes are treated as an ownership transfer.
Renewal and pending issues
Monitor payment and registry notices. Unresolved holder, payment or DNS issues can affect new requests or delegation.
Website and email records
Save DNS records before changing nameservers or providers so active services can be recreated safely.
Category compliance
Continue using the domain lawfully and maintain any qualification or authorisation required by a restricted category.
.br domain questions
Can a UK individual register .com.br directly?
The standard rules require a person legally established in Brazil with a CPF and local contact. The official foreign route described by Registro.br specifically addresses foreign companies with a legal representative in Brazil. Ask UKC to confirm any route available for your applicant type.
Can a UK company register .com.br?
A foreign company can apply through a legal representative established in Brazil, subject to the official foreign-registration procedure and required documents.
Is .br the same as .com.br?
No. .br is the country-code top-level domain and .com.br is a major category beneath it. Direct second-level .br registrations are not the normal general commercial route.
Do all .br categories have the same requirements?
No. Some categories are generic, while others require a specific profession, organisation type, documentation or government authorisation.
Can UKC guarantee acceptance?
No. The registry and verification process determine whether the holder, category, name and technical setup meet the rules.
Can accented characters be used?
Registro.br accepts specified Portuguese accented letters and ç, but its equivalence rules can block a name that corresponds to an existing unaccented or hyphen-free name.
