Thread: Diners Club - Discover - MasterCard ??

I have recently got a Diners Club card, which is issued by Hyundai Card here. It has 14-digit number starting with '3' and the 'Discover Network' and 'Pulse' logo on the back but no MasterCard logo or anything.
I heard about the Diners Club - MasterCard alliance some years ago that the Diner Club cards issued in the US and Canada will from then on have 16-digit numbers starting with '5' (which is the MasterCard numbering scheme) while the cards issued in other countries will still have 14-digit numbers but will be accepted in US and Canadian stores with the MasterCard logo (and the MC logo will also be printed on the back of newly issued Diners Club cards).
What I also heard in 2008 was that the Diners Club network was acquired by Discover Network.
Now I have a question. Will my Hyundai Card- issued Diners Club card with Discover Network logo on the back be accepted at US or Canadian stores showing the MasterCard logo? Or will I be able to use my Diners Club card in stores with the Discover Network logo?
What about in countries other than US and Canada?
I know I should ask the issuer for these kind of questions, but they don't seem to be any clearer than me on this thing

That's a good question. Well I do know that fortunately most places here in the US do accept Discover card anyway, so whether or not it is associated with MasterCard, if should still be accepted.

I tried searching for an answer and this is tough. The problem is that the ownership of Diners Club is pretty complicated. The rights and license agreements vary country by country so there's no universal answer. From what I recall the Mastercard partnership with Diners Club was only for cards issued in the USA.

I have a Discover card (US issued) and it is also 16 digits. My guess would be that if you use it here it would be processed at all places that take Discover. However if there is no Mastercard logo on it than I don't think it will work as a Mastercard.

Thanks Mogul of Pineapples for your reply. I guess you're right that the Diners Club - MasterCard alliance was mainly for the cards issued in US and Canada.

Hyundai Card finally sent me an answer on this. According to what they say, the Diners Club card I have can be used at US and Canadian stores where Diners Club, MasterCard, Discover cards are accepted. But not after 30th June 2010 at MasterCard stores. In any other countries than US and Canada, my card will be accepted as is, i.e. usable at Diners Club stores, not Discover or MasterCard. They're working on it so I can use my Diners Club card at non-US or Canadian Discover stores overseas, maybe in a couple of months. One good thing for Discover cardholders: you'll be able to use your Discover card in Korea from late this year, through the Hyundai Card network.
