Verify WhatsApp accounts in bulk with one click. Download Excel, CSV, or JSON results for marketing workflows. Number Checker for wa is a bulk WhatsApp number checker built for browser-based verification. It tests whether multiple user IDs or phone numbers are available on the service and replaces repeated manual lookups with a single workflow through WhatsApp Web. It is designed for people who maintain permission-based contact lists for customer support, sales, operations, or data review. The extension accepts a group of identifiers, opens the web client when a check starts, and processes the list. This helps reduce repetitive work during both quick checks and larger verification tasks. How to use 1. Open the extension by selecting its icon in the browser toolbar. 2. Enter or import the user IDs or phone numbers you want to check. 3. Click Check numbers. The web client opens automatically and begins the batch check.
