Have a GiftCardMall prepaid Mastercard? You need the MCgift portal at mcgift.giftcardmall.com — a separate portal from MyGift. Using the wrong one causes errors.
Using the wrong portal is the #1 mistake. The rule is simple:
Works for both activation and balance check on GiftCardMall Mastercard cards.
Type mcgift.giftcardmall.com directly into your browser (also at www.giftcardmall.com/mcgift).
Input your 16-digit Mastercard number, expiration date (MM/YY), and the 3-digit CVV from the back of the card.
Choose balance check or card activation. For activation, register your billing ZIP code at this step.
Submit. Balance results and card activation are both instant.
