This is an App Store and iTunes gift card issued for Türkiye: the value is added to the balance of the Apple account in Turkish lira and can only be redeemed on an Apple ID whose country is Türkiye. For those with a Türkiye Apple ID it is a way to pay for in-app purchases and subscriptions without linking a bank card. Before you buy the card, check in the iPhone settings that the country of the Apple ID is Türkiye.
A region mismatch is not grounds for a refund, so check the region before you pay. If a code does not work, contact support within 48 hours of receiving it, with a screenshot of the error. After payment the code appears under “Orders” in your account.
