^(62\d{14,17})$ - Visa Card:
^4\d{12}(?:\d{3})?$ - Visa Master Card:
^(?:4\d{12}(?:\d{3})?|5[1-5]\d{14})$
Remove all non-digits from the string, then use this for Visa, MasterCard, American Express, Diners Club, Discover, and JCB cards:
^(?:4[0-9]{12}(?:[0-9]{3})?|[25][1-7][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\d{3})\d{11})$
As of 2016-10-14 the MasterCard regex here will be insufficient as they will be adding a new range of 222100-272099. I just added the following for our validation (Slagmoth):
^(?:5[1-5][0-9]\d{1}|222[1-9]|2[3-6][0-9]\d{1}|27[01][0-9]|2720)([\ \-]?)\d{4}\1\d{4}\1\d{4}$
Note: Switch hasn't existed since 2002, Laser was withdrawn in 2014, Visa are due to issue 19 digit cards and MasterCard are now issuing in the 2xxxxx ranges.
