GiftCardRescue.com has launched a site GiftCardBalance.com that lists the contact information (URL’s and phone numbers) for quite a few gift cards. It is a convenient place to find the balance check information. Or, you could just look on the back of your card for the same information, seeing as you are going to need your card to actually check the balance.

A site where you could actually enter any gift card number and select the issuer to check the balance would be more helpful.

Update 5/19/10:  Something is funky with the GiftCardBalance.com site and it appears that it may no longer be trustworthy, especially in light of recent scams involving fake gift card balance sites.
