Some codes are restricted by region or server. Please look carefully at the listing information to see if the code has any kind of restriction. Please feel free to comment on the listing asking the Seller about this information if that isn't clear.
If a listing states a region restriction, this means it can only be used in that region.
If you purchase a code that is not available in your region, then you cannot activate and play it.
Note: If you purchase a code from another region and such restriction is clearly described in the listing restriction, the purchase won't fall under the Gameflip Guarantee, thus no refund will be possible.
