## Guide & FAQ

### How to check Twitter username availability

1. Enter a username, with or without the @.
2. Press Check username.
3. Read if an active account holds the name.
4. Open the holder's profile, or try the name in X's sign-up.

### What the username checker looks up

It looks for an active account with that exact name. Case doesn't matter, so NASA & nasa are the same name. A username has 1 to 15 letters, digits or underscores.

### What each result shows

A taken name shows the holder's name, picture, followers & join date. Otherwise the result says no active account uses it. X may still hold it for a suspended, deactivated or reserved account.
