X · Twitter
X (Twitter) username checker
Check an X handle, with the honest caveat about what X will tell us.
Checked alongside your domain and every other platform.
The rules
- 15 characters maximum — the tightest limit of any major platform.
- Letters, numbers and underscores. No full stops, no hyphens.
- The words twitter and admin are restricted.
How we check it
We request the public profile page. A genuine 404 is a real answer; anything else, we don't read into.
X renders profiles in the browser and serves everyone else the same shell, so most lookups honestly resolve to Unknown. The endpoint that used to answer this properly now needs a logged-in session, and using it would mean impersonating one. We don't do that.
Let X set your name length
Fifteen characters is the ceiling everywhere else has to fit under too. If your name works on X, it works on all of them.
Dormant isn't free
An abandoned account still holds its handle. There is no queue and no way to be next in line.
