Free WhatsApp Bulk Number Checker Chrome extension is a convenient and 100% free tool for quickly verifying multiple WhatsApp numbers in bulk. Designed for business owners, marketers, and anyone looking to streamline their communication efforts, this extension allows users to validate WhatsApp numbers directly from the web.

HOW IT WORKS?

Step 1. Open WhatsApp Web on your browser and login

Step 2. Paste or import a list of phone numbers (with country codes)

Step 3. Click on START CHECK button and the extension will check each number’s status on WhatsApp Web, indicating whether the number is registered on WhatsApp.

This extension operates efficiently by leveraging WhatsApp Web, accessing the platform in the background to verify each number and displaying results in real-time. It features a “Start Check” button to initiate the validation process and a “Stop” button to halt it if needed. Additionally, users can export verified numbers as a CSV file for easy integration with contact lists or marketing campaigns.
