X (Twitter) Username Checker
Check whether an X (formerly Twitter) handle is available, and whether the same name is open across the platforms your brand needs. The 15-character limit makes good handles scarce, so check early.
X (Twitter) username rules
An X (Twitter) handle is at most 15 characters and may use only letters, numbers, and underscores, no other symbols. It cannot be made up only of numbers, and it cannot contain the words "twitter" or "admin". Unlike most platforms there is no cooldown, you can change your handle as often as you like, but the moment you do, your old handle is open for someone else to claim.
What to do if your X (Twitter) name is taken
If an X handle is taken, the tight 15-character ceiling rewards short modifiers, "hq", "app", "_co", or dropping a vowel. Because people cross-reference your handle on a website, Instagram, and beyond, confirm the same name is free across 45+ platforms with the search above before you switch.
