Can you check the balance of a MasterCard GiftCard online?

Balances on MasterCard prepaid gift cards can be checked online at GiftCards.com, which can also supply balances for Visa and Discover gift cards as well as those of many retailers. Typing in the gift card number and security code brings up the balance on the card, according to GiftCards.com.

MasterCard gift cards must be activated before use, though many sold in retail locations are activated upon purchase. These gift cards can be used at any location that accepts MasterCard debit cards. They are valid until the preloaded amount of money on the card is spent or until any expiration date is reached, states MasterCard.
