You can also generate valid credit card numbers for specific Issuing Networks by utilising their particular prefixes.
To teach you how to manually validate a specific number, lets do an example: Say we have In order for a credit card number to be valid, it has to be validated by the MOD 10 algorithm.
This is an algorithm specifically designed to prevent accidental errors such as typos.
The MOD 10 algorithm is a checksum (detection of errors) formula which is the common name for the Luhn algorithm.
This formula has been in use to validate a lot of identification numbers besides credit cards since its development by scientist Hans Peter Luhn from IBM.
For the technically inclined, this number complies to the ISO/IEC 7812 numbering standard.
