Can't redeem my gift code form a friend

Gifted codes are region locked so they will only work in the region the sender is from. In order to use them, your account region and your physical location would have to match the sender's. Your friend can try contacting support for a refund and then buy
a code from somewhere else to send you.

Here is a guide for issues when gifting:

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."

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.
