Keep in mind, not all credit cards have 16 digits. Visa can have 13 or 16. And AMEX, Diners Club, enRoute, and JCB have 15. You can also use the LUHN formula to determine the it's actually a credit card or not. http://en.wikipedia.org/wiki/Luhn_formula Not sure how you would implement that into a regex though. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
