Online store credit card issue

HI, i'm trying to purchase form the online store. I have a Maestro card, and the problem i have is that it asks for a Card Issue which my card does not have. It has valid from/to but no card issue. Any help?

Maybe it's not a supported card?

Maestro is a supported card because its optional on the list in the credit card info bit when checking out. Maestro cards don't usually have a card issue they have a valid from/to. So i dont know because it wont let me proceed without the card issue. Anyone else use a Maestro card in the store?

Used a Maestro card twice today in-store (once for my account, once for boyfriend's).

All Maestro cards I've ever owned have had an Issue Number. The one I used today has an Issue Number and an expiry date, but not a 'valid from' date.

A number of online stores tell you to put a zero if you do not have an Issue Number - have you tried that, or will it allow you to leave it blank?

Unfortunately some Maestro cards (i.e. Bank of Ireland) don't conform to the issue number standard. I'd try yeah_hi's suggestion of using a zero. If that doesn't work, trying putting in zeros to fill the field. If there's space for 3 digits, put in 3 zeros.

I tried putting a zero in the card issue box and it worked, the transaction went smoothly thanks for the help guys
