Xbox Live is the official matchmaking and content distribution service for the Xbox 360. When signing up for Xbox Live, you are prompted to create a Gamertag. A Gamertag is the name associated with your Xbox Live account and acts as your permanent ID. The easiest way to check the availability of a Gamertag is to use any of the free websites that scour the Xbox Live Gamertag database.
