Amazon eGift Card
Amazon Gift Cards are region-specific, so they will only work on the Amazon website of the country they were purchased for. Example: Amazon.de cards will only work on Amazon.de, the German Amazon website. If you bought a card for the wrong country, you will have to visit that country's Amazon store to use it. To see which country your card is for, please refer to the delivery email you received from us. The card you bought is named at the top of your redeem instructions and has the corresponding regional Amazon domain listed there.
In the delivery email you received from us, you will find which country domain the code is valid for listed at the top of your redeem instructions. You can always go to that corresponding Amazon website and use your gift card there.
When you receive this error message, it means that your code has already been used. This can happen when you’ve already tried to redeem it, which might have resulted in Amazon blocking your code for unknown reasons.
What you can do to solve this: Make sure you have entered your code correctly, and contact Amazon Customer Service to investigate the underlying issue of why your code is not working properly.
Amazon has very strict security measures in place. They might block your gift card if you are trying to redeem too many vouchers at once, use a VPN, have more than one account, or are trying to buy very expensive products with it. Only Amazon Customer Service can help you directly to get to the bottom of your issue. Please contact them for help accessing your code.
