social networks / which use the handle, which are free
Social media username checker
A social media username checker opens the public profile address of one handle on every network and tells you where it is already in use and where it is still free. UsernameLookup does this across 300+ public sites in one search, grouped by network type.
Each network gets one of three answers: found with a profile link, free, or unknown when the site did not give a clear reply.
See the whole network map for a handle
Most people check a handle the slow way. They open Instagram, type the name, then try TikTok and X, and stop after four or five networks. The handle looks free, it goes on the business cards, and a month later someone points out that the same name belongs to a stranger on YouTube and a dormant account on Reddit.
A checker turns that into a single list. You type the handle once, and every network is asked the same question in parallel: does a public profile answer at this address? The result is a map of the handle across social, video, developer, gaming, forum and marketplace sites.
The point is not just a yes or no. It is the pattern. A handle free on the five networks your audience uses is worth more than a handle free on twenty networks nobody in your market visits.

How networks are grouped in the result
A long flat list of sites is hard to act on. The checker sorts every network into a category, so you can read the block that matters for your project first and come back to the rest later.
| Category | Examples | Why the handle matters there |
|---|---|---|
| social | Instagram, TikTok, X, Threads, Facebook, Pinterest, Snapchat, Bluesky, Mastodon | Where most brands and creators want one consistent handle |
| video | YouTube, Twitch, Vimeo, Kick, Dailymotion | Handles that appear in links, overlays and spoken intros |
| dev | GitHub, GitLab, npm, Docker Hub, Dev.to | Package names and org names that end up in install commands |
| gaming | Steam, Xbox, Chess.com, Roblox, Lichess | Player names that friends search to add you |
| forums | Reddit, Hacker News, Quora, Discourse communities | Names that carry years of post history once claimed |
| marketplaces | Etsy, eBay, Fiverr, Gumroad, Ko-fi | Shop names that customers type into the address bar |
Adult and explicit sites are left out of the catalog on purpose.
What each state tells you about a network
Social networks are inconsistent about missing profiles. Some return a clean not found page, some show a login wall, some answer with a normal page that just says the account does not exist. We read each network with the signal it really uses, so the three states mean something.
-
In use
A public profile answered at the address. You get the link, the response time and the date we first saw it. Open it and judge whether the account is active or abandoned.
-
Free
The network gave its own not found signal for the handle. This is the list to register from, starting with the network where the name is hardest to get.
-
Unknown
The network timed out, rate limited the request or changed its page. We say so rather than guess, and the link lets you check by hand in one click.
Three common reasons to run a social check
Launching a brand
Before the logo is final, check the shortlist on the networks your customers use. Pick the name that is free in the most places that matter, then claim the handles and the domain on the same day.
Growing as a creator
If your handle is taken on one new network, a check shows whether a small variation such as an underscore or a short suffix is free everywhere at once, so your name stays consistent.
Cleaning up old accounts
Teams that changed names often leave old handles behind. A check on the former name shows which networks still carry a public profile that customers might mistake for the current brand.
When the domain matters as much as the handle, the username availability check adds 25 domain extensions to the same run. If you already own the handle and want to see every public profile that uses it, find social media accounts by username focuses on the profiles themselves. To get alerted when a copycat appears on any network, use brand impersonation monitoring.
Public profile checks only
The checker requests the same public addresses any visitor can open without logging in. It does not sign in to networks, read private accounts or collect anything beyond the public answer. Anyone who prefers that a public profile does not appear in results can use the opt-out page.
Your first search is a one-time demo that shows the first found networks in full. Paid plans unlock every network and category, start at $24 a month billed yearly and include 300 checks a month on Pro. The full table is on pricing.
- Letters, digits and underscores only
- Between 4 and 15 characters
- No period at the start or the end
- No hyphen, since X does not accept it
A handle inside these limits can be registered on every large social network.
Questions about checking social media usernames
Which social networks does the checker cover?
The large networks such as Instagram, TikTok, X, Facebook, Threads, Pinterest, Snapchat and LinkedIn, plus video, streaming, developer, gaming, forum and marketplace sites. In total a search covers 300+ public sites, grouped by type so you can read the social block first.
What is the difference between taken and found?
They describe the same state from two angles. When a public profile answers at the address, the handle is in use on that network. In the result it is marked found, with a link to the profile, and in availability mode the same result reads as taken.
Can I check only social networks and skip the rest?
Yes. Choose the social category before you search and the run is limited to social networks. You can switch other categories on later and run the same handle again.
Does a free result mean I can register the handle?
It means the network returned its own not found signal for that address at the time of the check. Some platforms reserve names or hold deleted handles for a while, so treat free as a strong signal and register the handles that matter the same day.
Do you look at private accounts?
No. We only request public profile addresses, the same pages anyone can open without logging in. Private content, messages and login areas are never touched.
