How X usernames work
X usernames are short unique @handles. Checking availability first helps you avoid an invalid handle or one that is already taken.
Usernames are 4 to 15 characters
X requires at least 4 characters and allows up to 15. That is one of the shortest limits among major platforms.
Only letters, numbers, and underscores
Spaces, periods, hyphens, and emoji are not allowed. Usernames are not case-sensitive.
Shorter is usually better
Short handles are easier to remember, mention, and brand. If your first choice is taken, try an underscore or a short modifier.
Available does not mean reserved forever
If a username looks available, claim it soon. Popular handles can be taken quickly, and some may still be reserved by X.
