X / Twitter Username Availability Checker

Check whether a Twitter username is valid, open the X profile lookup and generate close alternatives.

Use 1-15 letters, numbers, or underscores.

X username rules

Usernames can use letters, numbers and underscores and must fit the 15-character X handle limit.

Try short prefixes or suffixes that preserve the brand: get, try, hq, app, co, or an underscore variant.

Can this guarantee availability?

The page validates the format and opens the public X lookup. X is the final source for whether a handle is claimable.

What characters can a handle use?

Letters, numbers and underscores.
