Friend from a different region gifted me a code

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.

He would need to see if he can refund the purchase and try to purchase a code from a retailer that would sell a Canadian code.

You can have your friend contact support explaining you didn't know and maybe they'll be nice enough to refund! Happened to me once, I'm in Canada and my friend is in the USA, he gifted me a game as a surprise but I was unable to redeem. Support gave him
a refund as it was the day of the purchase.

Nope. There's no way around region locking.
