Visa, Mastercard Length Question

[mensimageconsultant]

Recently a would-be customer wrote in, sounding like he has a Visa or Mastercard that has more than 16 digits and therefore isn't compatible with the website. Unfortunately, he hasn't responded to a request for specifics.

A search isn't turning up existence of any such cards. Short of calling the companies, do you know anything about it? Thanks.

He might have mistaken the security number--sometimes listed on the front--for additional account numbers.

Did he add his 3 digit security code to the end of it?

edit: beaten to th punch

Visa and Mastercard's credit card numbers are only 16 digits in length. However, some bank/debit cards go up to 19 digits (including Mastercard's Maestro cards).

The request for more details asked about bank issue. That's probably it. Thanks. Sorry for putting this in the wrong forum
