Bought my friend in a different region a game and as code is different region code they...

My friend send me a gift card but i can't redeem it.

it say "This code can't be redeemed. It was purchased in a different region from your account."
how do you redeem the code from my friend that live in different region.

You cant. Your friend will have to request a refund for the code and purchase a code for you that is meant for your region.

if your friend is in a different region, he would have to try finding a code from a retailer that sells them for your region. Gifting through Xbox is region locked and Microsoft will not swap the code from a different region.

My friend gift me minecraft but his region and i are different.
I don't know to able to accept the gift code.

You cant. Your friend will have to request a refund for the code and purchase a code for you that is meant for your region. The region of the code must match the region of your account.

The code would be region specific so if you got the code from a different region to your friends then it won't work.

You can't use codes from other regions, your friend will have to see if he can get a refund.
