General Questions

How do I check if a username is available on eBay?

To check eBay username availability:

  1. Visit usernameinspector.com
  2. Select eBay from the platform checkboxes
  3. Enter your desired username in the text field
  4. Click "Generate Links"
  5. Click the generated eBay link

If eBay shows "Sorry, this user was not found," the username is available. If an active profile loads, the username is taken. For a detailed walkthrough with three different methods, see our guide on how to check eBay username availability. You can also do a broader eBay username search to find existing sellers or look up any user profile.

Can I check multiple usernames at once?

Yes. Username Inspector supports bulk username checking. Enter usernames separated by commas (example: "username1, username2, username3") and the tool will generate check links for all of them across your selected platforms. This saves significant time when brainstorming username options.

Can I check username availability across multiple platforms simultaneously?

Yes. This is one of Username Inspector's core features. Select multiple platform checkboxes (eBay, Poshmark, Depop, Etsy, Grailed, Vinted, Mercari, Whatnot, Bonanza, Ruby Lane, Chairish) before clicking "Generate Links." The tool will create check links for each username on every selected platform, allowing you to verify brand consistency across all platforms at once.

Technical Details

How does Username Inspector check username availability?

Username Inspector uses a direct link generation method:

  1. The tool generates direct URLs to user profile pages on each platform
  2. These URLs follow the pattern: platform.com/username
  3. When you click a link, the platform attempts to load that user's profile
  4. If the platform displays "user not found" or similar, the username is available
  5. If an active profile loads, the username is taken

This method is fast, reliable, and works without API access or web scraping.

Does Username Inspector store my username searches?

No. Username Inspector prioritizes privacy:

  • No usernames are stored or logged
  • All processing happens in your browser (client-side)
  • No data is sent to external servers
  • No tracking cookies are used
  • Your searches are completely private

We use Google Analytics only to track page views and traffic sources, not individual username searches.

Use Cases

Why would I need to check usernames across multiple platforms?

Brand consistency across platforms provides several benefits:

  • Customer Recognition: Customers can easily find you on any platform
  • Professional Image: Consistent branding looks more established
  • Cross-Platform Marketing: Easier to promote one username across channels
  • SEO Benefits: Consistent naming helps with search visibility
  • Brand Protection: Prevents others from using your name on different platforms

For resellers and small businesses operating on eBay, Poshmark, Depop, Etsy, and other platforms, username consistency is a simple but effective branding strategy.

Troubleshooting

When using the "Open All Tabs" feature, browsers often block multiple popups. Solutions:

  1. Allow popups: Enable popups for usernameinspector.com in your browser settings
  2. Click individually: Instead of "Open All Tabs," click each check link one at a time
  3. Use keyboard shortcuts: Ctrl+Click (Cmd+Click on Mac) to open links in new tabs without popup blocking

Most browsers show a popup blocking notification in the address bar - click it to allow popups from our site.
