On your profile page, click on the “Edit Profile” button. 5. Under the “Gamertag” section, enter the gamertag you want to check in the “New gamertag” field. 6. Click on the “Check availability” button. 7. If the gamertag is available, you will see a green checkmark next to the field. If the gamertag is not available, you will see a red X next to the field.
