# X / Twitter Username Checker

> A free screening tool that compares one X handle across X, Instagram, TikTok, YouTube, Pinterest, and Bluesky.

## What it does

- Checks public-profile signals automatically for X, Instagram, YouTube, and Bluesky.
- Provides direct verification links for TikTok and Pinterest.
- Labels a missing public profile as likely available rather than confirmed available.
- Requires no Solnk signup or email.

## Limits and interpretation

- A missing public profile is not a registration guarantee.
- X says suspended or deactivated usernames may remain unavailable.
- X usernames can be up to 15 characters and use letters, numbers, or underscores; some names such as those containing X or Admin are restricted unless official.
- Availability on X does not imply availability or validity on another platform.

## Cost and access

The tool is free to use and does not require a Solnk account. Use the [interactive tool](https://solnk.com/tool/x-handle-checker) to perform the task.
