text: how can i check gift card balance on multiple cards? is there a website where i can check the balance of several gift cards i have received or must i contact them all individually there should be a number on the back of the cards that you can call and find out the balance. you should check them because though these are gift cards, if you don't use them by a certain period of time you actually can lose money on them. the companies will start charging against the cards.   i would even check the stores that the cards were purchased from, some stores now have devices throughout them that allows you to scan your gift cards and it gives you the balance.
