You can use your card:
Anywhere Mastercard is accepted, in-store or online depending on the type of card you were issued. Note: Some virtual cards can not be used in-store.
In the U.S. and, for most cards, internationally (except in blocked jurisdictions)
Acceptance is always subject to merchant support for prepaid cards. Some merchants or specific terminals (e.g., gas pumps, vending machines, kiosks) may not accept prepaid cards.
Please note that for all foreign transactions, you may be charged a Foreign Transaction Fee which is equivalent to 3.00% of the total amount of the transaction in U.S. dollars.
