My Code has expired

If the code has expired there's nothing that can be done.

It's possible that the code has expired. Is there an expiration date on the paper the code came on?

If there is an expiration date on the code, it should say so on the card that has the code on it. Usually, its on the fine print areas. However, if you already have gold, then the code will not work anyways. it will only work if the gold account has expired
(at least in my experience).

Hey RareArrow,

Unfortunately it looks like this code has indeed expired on 4/11, and the Xbox Live message you received with the code does note the expiration date. Since the code has expired, unfortunately we are unable to assist further with this issue.

Unless the code has an expiration date on it, they typically don't expire.
