Requesting previously used personal gamertag as new gamer tag

If the system says a tag is taken, then it's in use somewhere on Microsoft's servers. Keep in mind that the tag system is in use on other Microsoft services. The system also doesn't see things like spaces as making a gamertag unique. So while you look up
"gamertag" and it doesn't show, it may actually be in use as "gamer tag".

There is no way to request a specific gamertag, but with the new gamertag policy, you can use a tag even if someone else has it. https://beta.support.xbox.com/help/account-profile/profile/gamertag-update-faq

The only reason it would have brought up a different gamer tag is if you signed into a different email address.

At this point if you do not remember the email address associated with your original gamertag you can contact xbox support by going to support.xbox.com/contact-us and requesting a call back or talking to a chat person give them your gamertag and if they
can verify ownership of the account they can give you the email address that is associated with that gamer tag

There's no way to request a gamertag and the tag service is in use on other Microsoft services, so even if it's not being used on an Xbox, it could be in use elsewhere. If the person who owns the gamertag does not sign into it in a 5 year timespan, the tag
will be freed up for use.

Hello There,

IK IR Y IP T When An Xbox Live Member Chooses An Xbox Gamer-Tag, They Have The Full Rights To Keep That Gamer-Tag Even Know If They Have Been Inactive For Years Along With No Gamer-Score & No Gold Membership, You Will Not Be Able To Request
For The Gamer-tag To Be Forced Changed. The Owner Of The Gamer-Tag Must Change It Himself Or When a forced gamertag change is imposed due to the Gamer-Tag Violated The Code Of Conduct In Any Sort Of Way, If the gamertag you enter is already taken, you are
prompted to try another gamertag.
Note Gamer-Tags are also tied to services like zune or games for windows live. If a gt doesn't exist on xbox, it might be in use on one of those services. If you try sending the Gamer-tag you want a friend
request and it says it’s not a valid Gamer-tag that just means it isn’t used on xbox live, but it could be used for zune or gfwl.

One thing to remember is that spaces and capitalization don’t make your Gamer-Tag unique. For example, “”, “PR1NCEDARKNESS”, and “” They Are All The Same Gamer-Tags.

Hello There Relic Micro

As x24hrs2livex has previously stated,

Note gamer-tags are also tied to services like Zune or games for windows live. If a gt doesn't exist on Xbox, it might be in use on one of those services. If you try sending the gamer-tag you want a friend request and it says it’s
not a valid gamer-tag that just means it isn't used on Xbox live, but it could be used for Zune or gfwl. I thought this Information would help you understand Relic,
