What is a Brazilian CPF?

The CPF (Cadastro de Pessoas Físicas) is the 11-digit Brazilian individual taxpayer registry number. It is required for opening bank accounts, signing contracts, and filing taxes with the Receita Federal.

How are the CPF check digits calculated?

CPF has two check digits at the end. The first is computed by multiplying digits 1-9 by weights 10 down to 2, summing, taking modulo 11, and subtracting from 11. The second uses digits 1-10 with weights 11 down to 2 the same way. Any result of 10 or 11 becomes 0.

What is the difference between CPF and CNPJ?

CPF is for individuals (11 digits). CNPJ (Cadastro Nacional da Pessoa Jurídica) is for businesses (14 digits). Both use modulo-11 check digits, and both are issued by the Receita Federal.
