Is there a zipcode on a microsoft gift card?

Does the information on your billing address match the region on your console?

Gift cards cannot be used to purchase gift cards. The Microsoft account balance is essentially the same as a gift card since funds typically come from Xbox gift cards.

This page covers most of those details. Check the FAQ at the bottom.

The important parts would be

"Do gift cards expire?

No, gift cards purchased at retail never expire. Note that promotional gift cards like those from Microsoft Rewards or Xbox Live Rewards do expire."

"What is the difference between a Microsoft Gift Card and an Xbox Gift Card?

The cards work just the same. Once redeemed to your Microsoft account, you can spend your balance at Microsoft Store online, on Windows, and on Xbox."

"Where can I spend a gift card?

Once redeemed to your Microsoft account, your gift card balance is available to spend when you shop at Microsoft Store online, on Windows, and on Xbox. Gift cards do not currently work at physical Microsoft Stores."

Should cover you. One thing I'm not certain with is if "gift cards" can be used to pre-order physical goods. Might want to check with Microsoft Store support on that?

Was it a xbox gift card or a microsoft gift card. I messed this up once and added a microsoft gift card.
