Threads Username Checker
Type a username and the checker tells you instantly whether Threads allows it. Then open the profile link: a real profile means it is taken; a "page not found" means it is free or reserved. The same name is checked against every other platform's rules below, so you can claim one handle everywhere.
- Between 1 and 30 characters
- Only letters, numbers, periods, underscores
- Threads usernames are your Instagram username
Same name on other platforms
Platforms block other websites from reading whether a name is taken, so the honest way to check availability is to open the profile link: a real profile means it is taken, a "page not found" means it is free (or reserved). The format rules above are the official ones and are checked instantly.
Threads username rules
- 1–30 characters
- Letters, numbers, periods, underscores
- Threads usernames are your Instagram username
Your Threads username is your Instagram username: 1–30 characters of letters, numbers, periods and underscores. Change it on Instagram and it changes on Threads.
Why no tool can promise a name is free
Threads does not publish an availability API, and browsers block other websites from reading Threads's pages. Tools that claim to check live availability are either guessing from a cached list or asking you to trust a server-side scrape that breaks often. Opening the profile link is the one method that is always right, and it takes two seconds.
Picking a username that works everywhere
- Letters, numbers and underscores only: that satisfies every platform at once.
- Keep it under 15 characters so it also fits X and Snapchat.
- Avoid periods: fine on Instagram and TikTok, not allowed on X, Discord display or Pinterest.
- If your first choice is taken, "Suggest alternatives" adds common, brandable suffixes.
