What Is a CPF?
The CPF (Cadastro de Pessoas Físicas - Individual Taxpayer Registry) is an 11-digit Brazilian document that identifies each citizen. The last two digits function as a security code, called a check digit, which ensures the mathematical validity of the number. Our tool generates CPFs that pass this validation, making them perfect for testing systems that require this format. Please note: The generated CPFs are mathematically valid but do not correspond to real people and should not be used for illicit purposes.
How to Use the Tool
The tool is very simple to use. Just click the 'Generate CPF' button. Instantly, a new valid CPF number will be displayed on the screen. It will already be formatted with dots and a hyphen, ready for you to copy and use in your tests. Each click generates a new number, ensuring the variety needed for your validations.
