The sponsor organization who provided you with and/or loaded your card may have placed restrictions on where the card can be used. Restrictions can be at certain merchants, merchant categories, or locations.
To verify if there are restrictions on your card, you can log in to your account here and look for the “Card Restrictions” option. You may also reach out to your sponsor to find out if there are any such restrictions or call the toll-free number printed on the back of your card and choose to speak with a representative.
