CPF Explained

What Is a CPF? Brazil's Tax ID for Foreigners

The CPF - Cadastro de Pessoas Físicas - is Brazil's individual taxpayer registry number, issued by the Receita Federal (Federal Revenue Service). Think of it as Brazil's equivalent of a Social Security Number (US), National Insurance Number (UK) or Steueridentifikationsnummer (Germany). It is an 11-digit number that uniquely identifies every individual in Brazil's tax, financial and administrative systems.

For foreigners, the CPF is the single most important document you will need in Brazil. Without it, you cannot open a bank account, rent an apartment, buy property, invest in Brazilian markets, register a company, get a mobile phone plan or access most government services. This page explains what a CPF is, what it is used for and what it is not. For step-by-step instructions on how to get one, see the complete CPF application guide.

What a CPF Is Not

A common source of confusion is what the CPF actually grants. Here is what it does not do:

• It is not a visa or residency permit. The CPF is a tax registration only. It does not affect your immigration status, does not authorize you to live or work in Brazil, and is completely separate from any visa application. See the Brazil visa guide for immigration information.
• It is not a bank account. Having a CPF is a prerequisite for opening one, but the CPF itself is just a number - it holds no funds and has no banking functionality.
• It is not a physical card (in most cases). The CPF number is what matters. While a physical card can be requested, it is rarely needed - the number alone is sufficient for all transactions.
• It is not a CNPJ. A CNPJ (Cadastro Nacional da Pessoa Jurídica) is the tax ID for companies and legal entities. Individuals get a CPF; businesses get a CNPJ. To register a company, each individual partner must first have a CPF. See registering a company in Brazil.

The CPF Number Format

A CPF number consists of 11 digits in the format XXX.XXX.XXX-XX. The first nine digits are the base number, and the last two are check digits calculated from the preceding nine using a specific algorithm. These check digits validate the authenticity of the number and prevent typos and fraud.

Once issued, your CPF number is permanent - it never changes, even if you change your name, nationality status or marital status. You keep the same number for life.

What a CPF Is Used For

Unlike tax IDs in many countries that are primarily for tax filing, the CPF is embedded in virtually every aspect of daily life in Brazil:

When Should You Get a CPF?

The short answer: as early as possible. If you are planning to move to Brazil, invest in Brazilian assets, buy property or do any business in the country, you should start the CPF application before you need it urgently.

• Before moving to Brazil: Apply remotely so your CPF is ready when you arrive. This lets you open a bank account and sign a lease within your first week. See the moving to Brazil guide.
• Before buying property: Real estate transactions require a CPF before a notary can process the deed. Get it sorted before you start house hunting. See buying property in Brazil.
• Before opening a bank account: Every bank requires a CPF. Digital banks like Nubank and Inter are faster for foreigners. See opening a bank account.
• Before registering a company: A CNPJ requires a CPF for every partner. Get your CPF first. See registering a company.
