What is a CPF Generator?

A CPF Generator is a tool that generates valid CPF numbers, useful for testing and system development. It applies the official CPF validation algorithm to ensure that the generated numbers are correctly formatted.

How does the CPF Generator work?

The CPF Generator randomly creates the first nine digits of the CPF and then calculates the two check digits using the official validation algorithm, ensuring that the generated number is valid.

CPF (Cadastro de Pessoa Física) is a personal identification number used by the Brazilian government to recognize citizens and foreigners residing in Brazil. Composed of 11 digits, it is essential for various activities, such as opening bank accounts, making purchases, hiring services, and other identification-requiring processes.

How is CPF formatted?

CPF is structured as follows: the first nine digits are organized into three groups of three numbers, separated by dots, followed by a hyphen and the last two digits, known as check digits (DV). For example, the number 12345678909 is displayed as 123.456.789-09.

How to Determine the CPF Issuing State?

The Brazilian state where a CPF was issued can be identified by the last number before the two check digits.

Can the CPF numbers generated here be used on real documents?

No, they're generated randomly and have no connection to Brazil's Federal Revenue Service. They're only meant to fill in test forms, so they don't work as real identification.

Who's responsible if I misuse a generated CPF?

You are. This tool exists for software testing, so any use outside of that is on you, since we have no way to track or control what happens to the numbers once they're generated.
