Hello, Fist post, so please let me know if I have posted to the wrong place.
Our third party credit card processor has advised us that Mastercard numbers can be 16,17, 18, or 19 digits. Previously the card number was only 16 digits long. The Creditcard validator enforces 16 digits, but rejects card numbers that are 17, 18, or 19 digits long. I have tried to find "official" documentation on mastercard.com to verify this requirement, but I can only find anecdotal evidence at the moment. Perhaps someone on this list can provide more authoritative information? If so, is there a timeline for a possible fix? If we can find authoritative information to confirm the card number length I would be happy to make the change if someone will guide me through the process. Thank you, and please let me know if there is anything I can do to assist this effort. Regards, Bert
