Threads Username Checker
Threads profiles are created from an Instagram account, so the two apps share the same username pool and inactive-name policy. You can now use a Threads username that differs from your Instagram one, but some features expect them to match. Check a name below.
Threads username rules
| Link to Instagram | A Threads profile is connected to the Instagram account you log in with, in the same Meta Account. |
|---|---|
| Matching names | Using a different Threads username turns off the Threads badge on Instagram, sharing Instagram and Facebook posts to Threads, and the Meta Verified badge on Threads. |
| Ads | Mismatched usernames in Meta Business Suite pause Threads ads; Meta is phasing out this requirement from September 2026. |
| Inactive names | Threads and Instagram share one inactive username policy and do not hand out names from accounts that look inactive. |

How to check a Threads username
- Enter the name without the @. Threads uses the same character set as Instagram: letters, numbers, periods and underscores.
- We fetch threads.com/@<name>. Meta guards Threads closely against automated traffic, so expect more "Blocked" answers here than on smaller sites.
- For a hand check, open threads.com/@<name> in a browser. If Threads says the profile is not available, no public profile uses it.
- Also check instagram.com/<name>/: a name taken on Instagram is usually taken on Threads too, since the pools are linked.
Threads username taken? What you can do
- If you own the Instagram name already, keep the same name on Threads to keep the badge, cross-posting and Meta Verified working.
- Try the variations Instagram suggests for taken names: periods, underscores, numbers or abbreviations.
- Report impersonating accounts and trademark misuse with the same Instagram and Threads reporting tools.
How to change your Threads username
- In the Threads app, go to your profile and tap Edit profile.
- Tap your username and enter the new one.
- Review the warning about features that need matching usernames, then save.
Reserved and restricted names
Threads follows Instagram's rules on impersonation and trademarks: names that pretend to be another person or brand can be removed, and trademark owners can report infringing usernames on either app.
Tips
- Changing your Instagram username can change your Threads username as well if they are shared, so plan both together.
- Businesses running Threads ads should keep the names matched until the ads change reaches their account.
- Log in regularly; both apps encourage active use to keep the account clear of the inactive username policy.
Frequently asked questions
Can my Threads username be different from my Instagram username?
Yes, but some features stop working: the Threads badge, sharing posts from Instagram or Facebook, the Meta Verified badge on Threads and the paid partnership tool.
If an Instagram name is taken, is it taken on Threads too?
Usually, because Threads profiles are built on Instagram accounts. Check both before deciding.
Can I get a Threads name from an inactive account?
No. Threads uses Instagram's inactive username policy and does not release names on request.
