Social Security in Rio de Janeiro


The CPF (Cadastro de Pessoas Físicas or Natural Persons Register) is the Individual Taxpayer's Number and is one of the most important documents you can acquire. It is needed for many everyday transactions including opening a bank account, applying for a job, subscribing to a mobile phone company and when buying a car or property.

Each individual has an eleven-digit figure number which is printed on a blue plastic card. The last two numbers are the result of an arithmetic operation on the nine previous ones (which means that any typing mistake will result in an invalid number). The card is not always necessary is the number is memorized. The card is necessary for big purchases and verifying identity. The Federal Revenue has recently issued the "e-CPF", an electronic document that can be used as a nationwide, public-provided cryptographed signature key.
