What is a CPF?
The CPF (Cadastro de Pessoa Física, "registry of physical persons") is Brazil's national tax identification number. It's the equivalent of a US Social Security Number, a UK National Insurance Number, or a Canadian SIN. It's an 11-digit number, formatted like 123.456.789-00, assigned by the Receita Federal (Brazil's tax authority).
Unlike most national IDs, however, a CPF isn't restricted to citizens or residents. Anyone in the world can get one for free. And in Brazil, you'll need it constantly.
Bottom line: The CPF is free, takes 5 minutes online, and you should get it before you book your flight to Brazil.
Why you need one (it's not just for taxes)
Brazilians use the CPF for far more than tax filings. It's threaded into nearly every commercial transaction in the country. Here's what you can't do without one:
- Open a bank account. Every Brazilian bank, including foreigner-friendly fintechs like Nubank, Inter, and C6, requires a CPF before they'll open an account. While you wait, Wise gives you a multi-currency account that holds BRL alongside USD/EUR, most nomads keep using Wise even after their Brazilian account opens because the FX rate is better than any local bank.
- Sign a long-term apartment lease. Landlords and property managers will not draft a contract without your CPF on file.
- Buy a Brazilian SIM card. Vivo, Claro, TIM, and all prepaid resellers ask for CPF at activation.
- Buy on Brazilian e-commerce sites. Mercado Livre, Magazine Luiza, Amazon Brasil, Shopee, checkout forms have a CPF field. Many won't process the order without one.
- Make a Pix transfer. Pix is Brazil's instant payment system; your CPF is the most common "key" used to receive transfers.
- Buy domestic flights. Brazilian carriers (LATAM, GOL, Azul) require a CPF for both passenger and payer.
- Get a Brazilian driver's license. CPF is the unique identifier on the application.
- Pay utility bills (electricity, water, gas, internet) in your name. Even the deposit accounts require it.
- Buy property. Required for any real estate purchase, including the VIPER residency-by-investment program. See residency paths →
- Get tax discounts at restaurants and shops. Cashiers will routinely ask "CPF na nota?", adding your CPF to the receipt qualifies you for state tax-rebate programs (Nota Fiscal Paulista in São Paulo, similar elsewhere).
- Buy concert and sports tickets on Ingresso.com, Eventim, and most Brazilian ticket platforms.
- Use loyalty programs and pharmacy discounts. Drogasil, Drogaria São Paulo, supermarkets, almost every retailer ties their loyalty program to the CPF.
- Book a coworking membership or gym. Most Brazilian SaaS and subscription products have CPF as a mandatory checkout field.
You can technically live in Brazil without a CPF for a few days, by paying cash everywhere and accepting that some transactions will quietly fail, but you'll feel friction every single day. Get one before you arrive and the friction disappears.
The three ways to get a CPF
What you'll need before you start
- Your passport, number, country of issue, expiration date
- Your full legal name exactly as it appears on the passport, including all middle names and matching accent marks (or lack thereof)
- Your mother's full name (her maiden name, in many cases, use whatever appears on your birth certificate)
- Your father's full name, required even if the parent is unknown or deceased
- Your date and country of birth
- A residential address, your home address abroad is fine
- A reliable email address, your CPF number arrives there
Step-by-step: the online application
- Open the official Receita Federal portal: servicos.receita.fazenda.gov.br/Servicos/CPF/cpfEstrangeiro. Switch to English in the upper-right corner.
- Read and accept the terms.
- Fill in your personal data. Match your passport exactly, same spelling, same accents (or absence of), same word order. Mismatches cause more rejections than any other field.
- Enter your address and email. Use your home address abroad. The CPF number is delivered by email, so make sure that field is correct.
- Review the summary screen and submit.
- Save the protocol number shown on the success screen, you'll need it if anything goes sideways.
- Wait for the CPF email. Most applicants receive it within minutes. Some take up to 72 hours. If five business days pass with no email, fall back to the consulate route.
Common pitfalls and how to avoid them
"My nationality isn't accepted by the form."
The online portal sometimes rejects applicants from countries without a data-sharing agreement with Brazil. If that happens, switch to the consulate route, a Brazilian consulate can issue the CPF on behalf of any nationality.
"I don't know one of my parents' names."
Brazilian forms require both parents' names. If one parent is genuinely unknown, the most reliable option is to email the consulate first and ask how they want you to handle it. Some accept "Não informado" (not informed); others require you to write it on the form before submitting in person.
"I have multiple middle names on my passport. Should I include them all?"
Yes, copy your full name from the passport's machine-readable zone exactly. Skipping a middle name is the second most common reason for mismatched applications.
"I made a typo. Can I edit my CPF later?"
Yes. The Receita Federal allows you to update CPF data online or at any branch. You'll need supporting documents (e.g., your passport for name changes).
"How do I check if my CPF is active?"
Use the official status check page: CPF status verification. You'll need your CPF number and date of birth. Status should read "Regular".
"Do I need to pay Brazilian taxes just because I have a CPF?"
No. Having a CPF doesn't make you a Brazilian tax resident. Tax residency is triggered by physical presence (more than 183 days in any 12-month period), not by holding a CPF. Many foreigners hold a CPF for years without filing a Brazilian tax return.
Pro tips from people who've done this
- Get your CPF before you book accommodation. Long-term Airbnb hosts and property managers ask for it on the contract. Five minutes of upfront work saves a fortnight of friction.
- Save your CPF in your phone's contacts as the first entry, Brazilians ask for it constantly at checkout. Having it ready saves time.
- Don't share it casually. Like an SSN, the CPF is a key piece of identity. Don't post it publicly or share it with anyone you don't trust.
- If you're applying for the Digital Nomad Visa, get the CPF in parallel with your visa documents, they're independent processes.
- Print a card. Once issued, you can download a CPF card (cartão CPF) from the Receita Federal site. Useful for in-person ID checks.
