Hello Shz_Senpai,

Thanks for your post. I understand you are experiencing an issue with your Gamertag. For information on Gamertag and suffixes, check out:

Gamertag FAQ.

I hope this helps.

You have created a gamertag that was already taken therefore they gave you a number so you can still have the gamertag, it does warn you before you accept this
