Trying to change my username, but it says I cannot go above 12 characters, i haven’t seen...

That rule went into place in 2019.

Yes, I did try to change it back, but I already used my free Gamertag change. Anyways, it said that the characters has to be less than 12. I think they changed their username letter count, so I dont know if it says username taken or not.

It’s the same as if I was to try sign in on minecraft it says ‘cannot find username’ or ‘there is no account with this username’ even though there should be because I haven’t deleted it

Hi TheAbsol, my name is Jhon, and will be a pleasure help you

No, "Username" and "xbox username" are not the same according to Xbox.

Xbox usernames can be up to 12 characters, including spaces. However, usernames cannot begin with a number.

Therefore, "Username" and "xbox username" are two different usernames, since one has a space in the middle and the other does not.

If you're trying to change your Xbox username, but Xbox tells you it's in use, someone may already have that username with a space in the middle.

To check this, you can try searching for the username with a space in the middle in the Xbox player list. If you find a player with that username, then that username is already in use and you will not be able to change your username.

In this case, you will have to choose a different username.

Best regards

Sorry for not elaborating, I am trying to change username on a child account and cannot find out where the request for username changes go.
