Foreign prepaid codes.

Also if you bought a foreign card like a us card instead of a Canadian or a uk cars for example and you have another it won't work prepaid codes are region specific

Its not a glitch you don't understand how the currency system works

Regardless of a compromise your us currency will stay us currency even if they migrated to the uae

The only way to get a uae currency is to buy a uae currency card or have a uae creditcard

You can actually screenshot it

If you'd want however as stated there is no way to get foreign currency cards on a local account except thru the prepaid currency cards

Your account region maybe us but you can enter foreign currency cards on this website

If you do it won't show up on the us account it will only show on the commerce.microsoft.com as foreign currency

Did you buy a prepaid currency card ? Or did you do it as a creditcard purchase

If it was a prepaidcard then you need to check with the source

Not nessarily

If your physical location doesn't match and you either use a VPN or a have someone else queue it for you or using a foreign redemption code

It will bypass the purchase filter but will still corrupt if you are on foreign ground
