GitHub Username Checker
Instantly verify if your desired GitHub username or organization name is available. Secure your namespace in one search.
Quick Answer: Is this GitHub username taken or available?
GitHub usernames are up to 39 characters, using letters, numbers and single hyphens, and cannot start or end with a hyphen. If an account is deleted its username is released immediately and anyone can claim it. GitHub also redirects links from a renamed account until someone else claims the old name.
How It Works
Type Your GitHub Username
Enter the handle you want to register or test in the search box above. No punctuation or @ symbol needed.
Instant Verification
See in seconds whether the GitHub name is yours to claim, plus the matching domain and other handles.
Secure the Match
If available, secure it immediately. If taken, we suggest smart alternative modifications to check.
Checking GitHub Username & Brand Availability
Securing a consistent identity is the cornerstone of building a cohesive online brand. With our free GitHub username checker, you can instantly scan for matching profile urls and handle availability.
Building a presence on GitHub helps you reach target customer groups, share content, and protect your intellectual property. Locking in your desired username early prevents brand impersonation or squatted accounts.
If your desired brand name is already taken on GitHub, our tool automatically provides alternative variations (adding standard prefixes or suffixes) to help you secure a consistent brand presence across all social media and domain extensions.
