Please note that the reverse of each Total Rewards card are unique to that level and card type, i.e. there are different manufacturer numbers for Gold, Platinum, Diamond, Diamond Companion, Seven Stars, Seven Stars Companion and WSOP cards. Plus there are special manufacturer numbers just for cards from Las Vegas that have the extra "LV" prefix.

The scan of the reverse shown is for the WSOP card that has the "P" suffix on the manufacturer's number. The Diamond level would have a "C" suffix.
