Hey, CSINKO! Unfortunately, once a code is redeemed on an account, there is no way to transfer it to another account. We are also unable to replace the code so that you can redeem a new one on your other account. You will need to either get another code
from a friend that doesn't want to use theirs, purchase the game on the second account you have, or use the account that you accidentally redeemed the code on to play the game solely. Thanks for understanding!

Hi Xhyrra, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

It is not possible to refund a redeemable code or to transfer the contents.

It was a code from the Chill Vibez pack from fortnite, we made an xbox account to link in epic games so we could log in xbox cloud gaming, the username was the same as the one in epic games so we assumed that it was the account and boom, gave us a brand new account.

Because once it has been redeemed it can't be unredeemed if it is console he can gameshare it

If you are trying to gift ultimate for cloud that.can't be shared

No you shouldn't have any issues, but that code will only work on the gamertag that you redeem it on. I gave my code to a friend that lives in the UK and they were able to redeem it just fine.
