• Apple Gift Cards

The Apple Gift Card was introduced in 2020 and is now the gift card to use in purchasing products, accessories, apps, games, music, movies, TV shows, iCloud, and more from Apple. Apple Gift Cards can be used in the Apple Store, the Apple Store app, apple.com, the App Store, iTunes, Apple Music, Apple TV, Apple Books, and other Apple properties.

You can use Apple Gift Cards to pay for products, subscriptions, and services from Apple online. Or spend Apple Gift Cards at the Apple Store or by calling 1-800-MY-APPLE. You cannot pay for an Apple Gift Card with an Apple Gift Card or Apple Account Balance. Apple Gift Cards can be used only in the country or region in which they were purchased.

You can use up to eight Apple Gift Cards at a time when you purchase online from Apple, or if you’re placing an order by calling 1‑800‑MY‑APPLE. You can use your gift card(s) with an Apple Account Balance and Apple Pay or one credit card.

Any value on an App Store & iTunes Gift Card or Apple Store Gift Card in your possession is valid.

To redeem any Apple Gift Card or App Store & iTunes Gift Card into your Apple Account Balance, simply enter or scan the PIN. We send electronic Apple Gift Cards to the card recipient via email. Using this email, the recipient can easily redeem the card’s value to their Apple Account Balance for online purchases or use the PIN at an Apple Store, on apple.com, and in the Apple Store app.

For physical Apple Gift Cards, the PIN can be found on the gift card insert. On previous-generation Apple gift cards, reveal the PIN by peeling or scratching off the covered area on the back of the card. For electronic gift cards, the PIN can be found in the email. Please keep the card in your possession until the order has been processed and delivered.
