Aug 04, 2009 · Keep in mind that Luhn algorithm is a validating algorithm, not a verifying one. Just because an identifier is in a valid format doesn’t mean that it’s a real identifier that’s currently in use. Luhn algorithm is best used to find unintentional errors in identifiers rather than providing any level of security.
