How to use Username Availability Checker
Check if a username is available across multiple social platforms simultaneously — Twitter/X, Instagram, TikTok, YouTube, GitHub, Reddit, LinkedIn, Pinterest, Twitch, and more. Enter the handle you want and instantly see availability status across all platforms in one view. Essential for personal branding, business naming, and securing a consistent username before announcing a new project or brand.
- Enter the username you want to check (without the @ symbol).
- Click Check to query all supported platforms simultaneously.
- Review the availability status for each platform (Available, Taken, or Unknown).
- Click any "Taken" result to view the existing profile on that platform.
- Try variations (append your niche, add an underscore, use initials) for taken names.

Why username consistency matters
Using the same username across platforms is critical for personal and brand SEO. When someone searches your name, Google shows profile results from major platforms (Twitter, Instagram, LinkedIn, YouTube) prominently in the results. Consistent handles make it easy for your audience to find you across platforms without confusion. Platform cross-promotion ("follow me @handle on all platforms") only works if the handle is the same everywhere. For businesses, securing your brand name on all platforms — even ones you don't plan to use immediately — prevents impersonation, cybersquatting, and future namespace conflicts.
Username naming strategies
If your preferred username is taken on some platforms, consider these strategies: add a relevant industry suffix (@yourname_dev, @yourname_photo), use an abbreviated version for platforms with short limits, add a country/city code for local brands (@yourname_uk), or use your full name instead of a handle. Avoid adding random numbers (yourname123) — they look spammy and are hard to remember verbally. Hyphens and underscores have different support across platforms: Twitter doesn't allow hyphens, GitHub allows hyphens but not underscores, Instagram allows underscores and periods but not hyphens.
| Strategy | Example | When to use |
|---|---|---|
| Industry suffix | sarah_dev | For professional accounts |
| Location suffix | pauluk | For local/regional brands |
| Full name | sarahmitchell | Personal brands with common first names |
| Underscore separator | sarah_j_smith | Disambiguation from common names |
| Brand abbreviation | smco | Short, memorable business names |
Worked examples

Inputs: handle "acmehq"
Result: availability across X, Instagram, TikTok, GitHub, and more
Taken handle
Inputs: a common name already taken on X
Result: try acmehq_uk, acme_hq, or a short brand abbreviation
