Online screen names and gamertags typically have no expiration dates. However, some online gaming companies might have rules permitting them to reclaim inactive or unused gamertags after a predetermined amount of time has passed. For instance, the platform may recover a user's gamertag and make it available for others if they haven't signed into their account or used it at a particular time. To determine if there are any provisions for reclaiming inactive gamertags, it's usually a good idea to examine the exact norms and rules of the site you're using.
