Checking the balance of an iTunes gift card is a simple process that can be done in a few different ways. Knowing your balance is important so that you can track how much money you have left to spend on apps, music, movies, and other content from the iTunes Store. You can check your balance online, through your iPhone or iPad, or by calling Apple Support.
To check your balance online, visit the Apple website and sign in to your account. Once you’re signed in, click on the “iTunes & App Store” link under the “Account” menu. On the next page, click on the “Redeem” link under the “Gift Cards” section. Enter the code from your gift card and click on the “Redeem” button. Your balance will be displayed on the next page.
