The Module 11 Algorithm
Have you ever tried entering \"111.111.111-11\" in a store registration and the system blocked it? That's because the last two digits of the CPF are not random, they follow a strict mathematical calculation. Our tool performs the mathematical equation to generate a fake document, however, it can fool any form validator for testing purposes (Do not use for fraud).
