How to Check Your Username Availability Everywhere
Your username is your brand identity. Learn how to check if your desired username is available across Instagram, TikTok, YouTube, X, LinkedIn, and 10+ other platforms — all in one place, in just 3 steps.
Enter your desired username
Open the SocialKit Username Availability Checker and type in the username you want to use across platforms. The tool checks Instagram, TikTok, YouTube, X (Twitter), Facebook, LinkedIn, Pinterest, Reddit, Twitch, and more — all at once.
Try variations if your first choice is taken: add a prefix like "the" or "real," or a suffix like "official" or "hq."
Click Check and review results
Hit the "Check" button. Within seconds, the tool displays a grid showing which platforms have your username available and which ones are already taken. Green means available, red means taken.
Take a screenshot of the results for reference while you create your accounts.
Claim your username on available platforms
Click on any available platform in the results to go directly to its signup page. Register your username on every available platform — even if you do not plan to use them all right away, claiming them prevents others from taking them.
Prioritize the platforms where your target audience is most active. Secure those first, then claim the rest.

Common questions
How accurate is the username availability check?
The tool checks each platform in real-time. However, some platforms may have cached results or rate limits. Always verify availability on the platform itself before finalizing your account creation.
What should I do if my username is taken everywhere?
Try adding a middle initial, a profession, a location, or a number. For example, "johndoe" could become "johndoe.design," "byjohndoe," or "johndoe.creative." Consistency across platforms matters more than having the exact same name.
Why should I claim usernames on platforms I do not use?
Claiming your username on all platforms protects your brand identity. Even if you are not active on a platform, having your username prevents impersonation and keeps your options open for future expansion.
Can I check multiple usernames at once?
Currently, the tool checks one username at a time across all supported platforms. For batch checks, run each username separately and compare the results.
