I found a few articles here and there, so you’re probably better off calling the CC company and inquiring. I do notice that Discover has stopped making these available (and they do so with an appropriately lame public reason):
Why is this program no longer being offered? Regrettably, the technology on which secure online account numbers are based is no longer available to us so we are unable to continue to offer it to cardmembers.I guess math went away or something. I would suspect that the number and scope of these hacks will force CC companies into offering some sort of burner number, otherwise they're shunting consumers into using the dispute process. Sadly, it's probably easier for them to soak up the cost of generating a new card or widening their dispute group than to offer an easy protection for cardholders.
