CPF Generator Frequently Asked Questions
Are the generated CPF numbers real?
No, these are test CPF numbers generated algorithmically for development and testing purposes only. They follow the correct format and pass validation checks but are not assigned to real individuals.
Can I use these CPF numbers for real registrations?
Absolutely not. These numbers are for testing and development only. Using fake CPF numbers for real registrations or official purposes is illegal and can result in serious legal consequences.
How does CPF validation work?
CPF validation uses a two-step checksum algorithm. The last two digits are calculated based on the first nine digits using specific mathematical formulas. Our generator creates numbers that pass these validation checks.
What's the difference between formatted and unformatted CPF?
Formatted CPF includes dots and hyphens (123.456.789-01) for display purposes, while unformatted contains only digits (12345678901) for database storage and API integration.
Development Tips
