In Bulgaria, UnionPay cards are accepted at 2,200 merchants. Since that some of the merchants have yet to put up the UnionPay signage, cardholders may show their UnionPay cards upon the till and inquire about UnionPay acceptance.
When using co-branded cards, you are advised to choose UnionPay as the routing option to be benefited from the special offers and services provided by UnionPay.
Note：Some UnionPay card acceptors or acquirers route co-branded cards to corresponding card shcem according to the card BIN, which means co-branded cards transactions aren't routed to UnionPay without selection by cardholders and merchant cashiers. Please refer to the transaction results for the information about transaction routing.
