Recently, MasterCard and Diners Club have entered into an alliance that requires a new set of rules for accepting Diners Club cards issued inside and outside of US.
Diners Club Cards which are issued in North America, have a 16-digit account number and a BIN beginning with "5" can be accepted and processed just like any MasterCard credit card transaction. There is no need to do anything here.
The new requirement is to accept Diners Club Cards which are issued outside of the U.S. and have a 14-digit account number, and a BIN beginning with "36" just like any MasterCard credit transaction.
Warning: Failure to comply with these new regulations may result in substantial fines!
