iTunes Store Gift Cards:
- When you redeem an iTunes Store Gift Card, the amount of credit on the card is added to your iTunes Store account. You can use it at any time to buy items in the iTunes Store, App Store, or iBooks Store, pay for in-app subscriptions, or make in-app purchases.
- If you received an iTunes Store Gift Card through email, click Redeem Now in the email to redeem the credit.
- After you redeem a Gift Card, your iTunes account balance automatically updates. You might need to sign out and back in to all of your devices for your credit balance to appear. You can find your balance underneath your Apple ID.
Content and promo codes:
- You can redeem content and promo codes for specific items in the iTunes Store, App Store, or iBooks Store on your iPhone, iPad, or iPod touch.
- All content or promo codes can be redeemed in iTunes for Mac or Windows except codes that are specifically for the Mac App Store. Redeem Mac App Store content or promo codes in the Mac App Store. You can also redeem iBooks codes in iBooks for Mac.
Other gift cards:
You can redeem Apple Store Gift Cards online, in an Apple Store, or over the phone. Learn more about the differences between iTunes Store Gift Cards and Apple Store Gift Cards.
After you redeem iTunes Gift Cards or iTunes Gifts, your updated balance appears in your iTunes Store account. Each time you purchase content, iTunes deducts funds from the credit until it's depleted.
The entire amount of a gift is credited to your iTunes Store account when you redeem it, so you don't need to enter your gift card number or gift code each time you want to buy something.
You can check your balance on your iPhone, iPad, or iPod touch, or on your computer through iTunes, the Mac App Store, or the iBooks Store.
