Xbox game codes can expire, but that doesn’t mean they’re gone for good. In fact, some Xbox game codes may still be valid after a certain period of time has passed. If you’ve ever received an Xbox game code in the mail and it didn’t work, it’s likely that the code had expired. However, there’s no guarantee that every Xbox game code will expire after a certain amount of time has passed. So if you’re ever curious about whether or not your Xbox game code still works, just check to see if it’s still being sent out or if it’s been replaced with a newer version.
