How do you use a Mastercard gift card to shop online?
Before you use your gift card, call the financial institution that issued the card or go to their website and add your name and address to the card. This will ensure that when you use the card online, the name and address you provide to the merchant for billing will match the name and address on file for the card. Once you have registered your card, you can use it online just like you would use a regular credit card.
