Check Username Availability Across Every Platform That Matters
A great brand lives or dies on consistency. When your handle is @yourname on Instagram but @yourname_official on TikTok and @real-yourname on YouTube, every mismatch costs you followers, makes impersonation easier, and makes your project look smaller than it is. The fix is simple: before you commit to a name, check it everywhere at once — then register it everywhere that matters, even on platforms you won't use yet.
Our checker searches your name in real time across social networks like Instagram, TikTok, X (Twitter), Facebook and Snapchat; video platforms like YouTube and Twitch; developer sites like GitHub and npm; music platforms like Spotify and SoundCloud; gaming services including Steam, PUBG and Roblox; professional networks; blogging platforms — plus domain availability for popular extensions like .com, .io, and .ai. Every result links directly to the platform's signup page, so claiming an available name takes seconds.
How to Use the Results
- Available everywhere? Move fast — register the domain first (it's the hardest to get back), then the social handles you'll actively use.
- Taken in one or two places? Consider a consistent variation across ALL platforms rather than different names on each. Consistency beats perfection.
- Taken everywhere? The name is probably too generic to own. Try our AI name generator to create brandable alternatives, or compare a whole shortlist at once with the bulk checker.
- Building a serious brand? An available name is not automatically a safe name — read our guide on usernames and trademarks before you invest in it.
Why Check Before You Build?
Renaming an established account means losing search results, breaking old mentions and printed links, and confusing the audience you worked hard to earn. Checking takes ten seconds; rebranding takes months. If you're still deciding what to call yourself, our guide on choosing a username that lasts walks through the exact checklist we recommend.
Frequently Asked Questions
How does the username availability checker work?
Type any name and we query each supported platform in real time — social networks, gaming services, developer sites, music and video platforms — plus domain availability. Each result links straight to the platform so you can register the name immediately.
Is the username checker free?
Yes. Checking usernames and domains on 360username is completely free, with no account or signup required, and no limit on how many names you can search.
Does checking a username reserve it?
No. A search only checks availability — it never registers or holds the name. Popular names get claimed fast, so if your name is available on a platform you care about, register it there right away using the direct link in the results.
Why does a username show as taken when the profile looks empty?
Many platforms keep deleted, banned, or reserved usernames locked for months or even permanently. An inactive or empty profile still counts as taken because the platform will not let you register that name.
What should I do if my username is taken on one platform?
First decide how important that platform is for your audience. If it matters, try a consistent variation — adding a short word like HQ, app, or your craft — and re-check it everywhere so your brand stays uniform. Our AI name generator can suggest available variations automatically.
Can I check many usernames or domains at once?
Yes. Use the bulk checker to paste a whole list of names or domains and compare their availability side by side — ideal for brainstorming sessions and client work.
