6X Shield Browser Extension
A free browser extension that checks any phone number for 6X verification and spam reports, with one-click free calling.
6X Shield is a free browser extension that checks any phone number you see on the web — is it a verified 6X business, or has it been reported as spam? — and lets you call it free, on-net, straight from the badge it shows.
Early access — not yet on the Chrome Web Store
6X Shield is brand new and not published to the Chrome/Edge extension stores yet. For now it installs manually, which takes about a minute:
- Download the extension using the button above and unzip it anywhere on your computer.
- Open chrome://extensions (or edge://extensions in Edge) in your browser.
- Turn on Developer mode (top-right toggle).
- Click Load unpacked and select the unzipped folder.
That's it — the 6X Shield icon appears in your browser toolbar, and it starts working on every page you visit.
What it does
- Any phone number already marked up as clickable (
tel:links) gets a badge automatically. - Plain phone numbers in page text get checked too — the detection is deliberately careful, so it won't badge dates, prices, or ID numbers by mistake.
- A green badge means the number belongs to a verified 6X business. An amber badge means no 6X data exists for that number yet. Either way, click the badge to call it free through 6X.
Spam warnings are still filling up
6X Shield can flag numbers reported as spam, but that part of the system is brand new — real spam reports haven't accumulated yet, so you won't see spam warnings right away. The verified-business detection is fully live today.
