Yes, its possible. You need to login on xbox.com, after go to profile and select friends. On the right side you will the option to find the player you want.

Hi Romans96,

Thank you for posting on the Xbox forums, I'd be happy to help.

If you go online to your Xbox account at http://account.xbox.com/, on the right-hand side of the page you will see a column with two tabs that say Messages & Friends. Click on the tab
that says Friends and then a search box will appear for you to find someone by Gamertag.

You also have the option of downloading the Xbox app for your mobile device and search from there. I hope this helps!
