Terrible.

- SwiftyBug 6y agoThey can tell weather a CPF number is valid or not. But I have tried giving them 123.456.789-09 which is mathematically valid, but it wasn't accepted. Maybe they have a verification for the actual existence of the number.
- sam_lowry_ 6y agoI guess that the last two numbers are the mod 97 checksum, so it should then be 123.456.789-39.
