There are two levels of cards in the World category that are authorised by MasterCard:

World
World Elite

The exact benefits and credit criteria are determined by the issuing bank. But all World products must have a rewards programs, certain travel insurances, a concierge service, and some type of lounge access (this is waived for the Citi AAdvantage World Elite card due to the relationship with AA).

Now, I'm not familiar with Priority Pass and not sure if you are talking about the names here. But the MasterCard will be either World or World Elite
