gamertag availability

Howdy Helmet!

You can search for a Gamertag on Xbox.com. First, navigate to your Friends Hub located through the Social Dropdown menu. Then there is a search bar titled "Find a Friend." there, search the gamertag you want to check the availability on, and it will bring you to a profile. (Or Not.)

Even with that search option, the best way to find out if a gamertag is available is by trying to change yours to it. The search option will not show you gamertags that are used on other Microsoft services and if you were to search for "Gamertag" it may not show it even though "Gamer tag" is in use. The system doesn't see the spaces as being different gamertags.
