The CPF, Cadastro de Pessoas Físicas, is an eleven-digit tax number, and in practice it is Brasil's master key. You'll be asked for it at the pharmacy, when buying a SIM card, signing a lease, opening a bank account, enrolling a child in school, and sometimes when buying groceries online. Not having one doesn't make these things impossible; it makes each of them slower, and some of them absurd.
The good news: you don't need to be in Brasil
Foreigners can obtain a CPF before arrival, and on every BFY route we do it as part of the file. It's one of the first artifacts sealed in your case. If you're doing it alone, there are three ways:
Start with the official Receita Federal CPF service. It provides channels for foreigners and residents abroad, the documents to prepare, and instructions for any additional document check. Depending on your application, follow-up may involve Receita Federal or a Brazilian consulate.
Check the channel: use the official service page to identify authorized application channels. Requirements and any charges depend on the channel. An intermediary is not required for a direct application.
CPF is not residence
A CPF gives you no immigration status whatsoever. It's a tax identifier; tourists can have one. Don't confuse it with the CRNM (your residence card), and don't let anyone sell it to you as a "first step to residency" as if it carried legal weight. It carries convenience, not status.
Guard the number, not the card
There is no physical CPF card anymore; the number is the document. Memorize it. Brazilians recite theirs like a phone number. Treat it like one: leaks happen, and personal details can be misused. Give it when asked by institutions; decline when the corner shop wants it "for the system."
On a BFY route? We confirm the CPF steps and documents needed for your case. If legal representation is needed, it is handled through our legal partners.
