The message “This code has already been redeemed” means the Xbox Ultimate coupon has already been successfully applied to some Microsoft account and cannot be redeemed again.
Steps to take:
- Confirm the correct account
- Go to https://account.microsoft.com and sign in with the account used in the Xbox app.
- Check Subscriptions to see if an Xbox Game Pass Ultimate (or similar) subscription is already active. If it is, the code has likely been redeemed to this account.
- Try redeeming from the account portal
- While still signed in at https://account.microsoft.com, go to Subscriptions → Redeem a code or gift card (or go to https://redeem.microsoft.com while signed in with the same account) and try entering the code again to confirm the error.
- Check for other accounts
- If the subscription does not appear on this account, the code may have been redeemed on a different Microsoft account (for example, another email previously used on Xbox). Sign out and try signing in with any other Microsoft accounts that might have been used, then check Subscriptions again.
- If the code was purchased as a gift card or promo
- If the coupon came from a retailer or promotion and cannot be found on any of the accounts, contact the retailer or promotion provider with proof of purchase and the error message. Some retailers can verify whether a code was redeemed and when.
- Contact Microsoft support if needed
- If it is confirmed that the code should be unused (for example, newly issued or from Microsoft Rewards) but still shows as already redeemed, contact Microsoft support for investigation. Provide the full 25-character code and any order or reward details.
Note: Gift cards and subscription codes, once redeemed, are tied to the Microsoft account used at redemption and cannot be moved or redeemed again.
