Social media username checker

By WhatsMyName Apps · Reviewed October 18, 2026 · Editorial policy

Social networks are where a handle matters most, because it doubles as your profile link and the name people tag. Each page below checks one network and lists its own length and character rules, so you can see why a name that works on TikTok gets rejected on Snapchat.

The checks are not all built the same way. Some networks show a public profile page we can test. X answers through its sign-up form, so taken names show even when the account is suspended. Instagram we do not query at all, because Meta's robots.txt does not allow it, so that result is always Unknown with a link to check by hand.

Frequently asked questions

Can I check one handle on every social network at once?

Yes. The full username search on the home page runs the same name against every site in our list, social networks included. The pages here are for when you care about one network and want its rules next to the result.

Why does Instagram always say Unknown?

We stopped requesting Instagram profile pages on 14 October 2026 because Meta's robots.txt does not allow automated collection. Open instagram.com/name/ yourself, or type the name in the app's Edit profile screen.

Does "Not found" mean I can register the name?

Not always. A name can be reserved, banned or held by a deactivated account and still show no public profile. The sign-up or edit-profile form on the network itself gives the final answer.

Do you store the handles I check?

No. The name is sent to our server to run the check and is not stored or logged.
