A handle valid on X but too short for it
X requires at least 4 characters — a 3-character handle is flagged as too short for X specifically, even while it might be valid-format on a platform with a shorter minimum.
Username availability checker
Enter a handle and get it validated against each of 10 platforms’ real username-format rules, plus a direct link to that exact handle’s profile URL on every platform — this deliberately does not claim to know live availability, since no static page can safely or reliably query every platform’s API for that; click through to see the real answer for yourself in one step.

How to use the handle availability checker
- Enter the handle you want. With or without a leading @ — either works.
- Review the format check per platform. Each platform has its own real length and character rules; an invalid format is flagged before you even click through.
- Click through to check availability. Each valid-format row links directly to that exact handle’s profile URL on that platform.
- Read the result on the platform itself. An existing profile, a "user not found" page, or a claim/signup flow tells you the real answer — this tool cannot.
- Repeat across every platform you care about. A handle valid and free on one platform may be taken or invalid on another — check each one you actually need.
Worked examples
A handle with a period on LinkedIn
LinkedIn’s profile slug allows only letters, numbers and hyphens (up to 100 characters) — a handle containing a period is flagged as an invalid format there, even though periods are fine on Instagram or TikTok.
Username availability checker FAQ
- Does this tool tell me if a handle is actually available?
- No — it validates the handle’s FORMAT against each platform’s real rules and links you to that exact profile URL so you can see the real answer yourself; a static page cannot safely or reliably check live availability across every platform’s API.
- Why not just build a live availability checker?
- Most platforms have no public availability-lookup endpoint, and the ones that do require an authenticated app and are rate-limited or against ToS to query this way from a public tool — so this tool is honest about that limitation instead of faking a result.
- What does "invalid format" mean?
- The handle breaks that specific platform’s own length or allowed-character rules (e.g. LinkedIn disallows periods; X requires at least 4 characters) — it would be rejected there regardless of availability.
- Which platforms does this check?
- All 10 SkedCast supports: X, Instagram, TikTok, YouTube, Facebook, LinkedIn, Pinterest, Threads, Bluesky and Telegram.
- Is my handle sent to a server when I use this tool?
- No — format validation happens entirely in your browser; the only network requests are the ones you make yourself by clicking through to a platform’s own site.
- Can I check a handle with a leading @ symbol?
- Yes — a leading @ is optional and stripped automatically before validation.
