Frequently asked questions
Does a valid CPF mean the person is real?
No. This page verifies the two mod-11 check digits only. It cannot query Brazilian government databases, so it cannot confirm registration or identity.
What does the test-number button do?
It creates a random number with correct check digits for development and form testing. It is for testing only and must never be used as a real identity.
Is my input uploaded?
No. Everything is checked locally in your browser and never leaves the page.
