A Google Play gift code adds to the Play balance of your Google account: it pays for apps, games, in-app purchases and subscriptions. Codes are tied to a country and are offered here in three variants: the USA, Europe and Türkiye. A code can only be redeemed on an account with the same Google Play country; you can see the country in the settings of the Play Store app, in the account section.
The region is shown in the product name and description. 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.
