CPF

How it works

Nine random digits are drawn and the two check digits are calculated with the official modulus 11 rule, so every number passes CPF validation.

Questions

Can I use the generated numbers for real registrations?

No. They are random numbers that happen to pass the format and check-digit rules. Use them only to test software, never to impersonate a person or company.
