You can easily change your Xbox LIVE gamertag. If your gamertag was created for you during Xbox LIVE sign-up, you can change the gamertag once for free. Additional Xbox LIVE gamertag changes cost 800 Microsoft Points.
To change your Xbox LIVE gamertag
On your Xbox console, sign in using the Xbox LIVE gamertag that you want to change.
Go to Social, and then select your gamertag.
Select Change Gamertag.
Note the Price of the change, and do one of the following:
Select Enter New Gamertag. If the gamertag you enter is already taken, you will be prompted to try another gamertag.
Select Get Suggestions to view possible gamertags.
Once you enter or select a new gamertag, select Yes, use this gamertag.
Note Click Add Microsoft Points if you don’t have enough points to complete the purchase.
Once you confirm your new gamertag, the change is reflected across Xbox LIVE. You don’t need to tell your friends that you changed your gamertag — their friends lists will be updated automatically.
Made a mistake creating your gamertag?
If you made a mistake when you created your gamertag and you want to change it, you’ll have to purchase a new gamertag. All gamertag purchases must be made through the dashboard and cost 800 Microsoft Points.
