Card expired!

There is no expiration date on the back of the card. The Xbox staff @E3 also did not mention an expiration date and made it sound as though there was no expiration date, or at least any expiration date soon. Honestly, I am extremely mad @Xbox and @Microsoft
for having expiration dates in the first place. Additionally, having expiration dates when there is no mention of an expiration date on the card? There should be an internal investigation on why no dates where noted on the cards and those with expired cards
from E3, with proper verification of an expired card from E3, should be given another code to use.

The Xbox Gift Cards do expire but the expiration date varies by card so you would need to check the card to find out the exact expiration date. Hope this helps.

If it expires, the expiration date would be on the card. Otherwise, they don't expire.

Cards can expire, but they usually would have the expiration date on the card.

Is the card for the same region as your account? If the card is from a different region it would not work.

Yo. My moms expired card is still there. I have another card thats not expired there, but I cant delete the payment option for the one thats expired.
