Questions about X usernames
Use the checker as a fast screening step, then confirm the final handle directly on each platform.
Type a username and the tool checks X, Instagram, TikTok, YouTube, Pinterest, and Bluesky in parallel. Results show whether each handle is taken or still available.
Six platforms: X (formerly Twitter), Instagram, TikTok, YouTube, Pinterest, and Bluesky. All checked simultaneously in one query.
The tool queries each platform's public endpoints, so results reflect current availability. A username shown as available can still be claimed by someone else seconds later, so register quickly if you find one you want.
No signup, no email, no rate limits for normal use. Completely free.
X usernames must be 4-15 characters long and can only contain letters, numbers, and underscores. No periods, no dashes, no spaces. The checker only returns availability — verify final eligibility by trying to register on X.
