About WAChecker
WAChecker is a Chrome browser extension for bulk-checking the registration status of WhatsApp numbers. Users can paste or import a number list, run the checks in the browser, view result statuses such as registered, not found, and pending, then filter and export the numbers they need to Excel. Lists and check results are processed locally within the browser extension—no WhatsApp Business API approval is required; just install the extension and log in to WhatsApp Web to get started.

Features
Bulk Import & Checking
Paste, generate, or import a number list (supports Excel import, manual pasting, and a number generator), process hundreds of numbers at a time, and automatically track progress and summarize results.
Verification via WhatsApp Web
Registration status is read from your current WhatsApp Web session, with speed controls to keep long-running sessions stable.
Clear Results & Filtering
Registered, not found, and pending statuses at a glance—filter results and export Success and Failed results separately.
Task Dashboard & History
Includes a dashboard and history log so you can view task progress and manage past records.
Local Processing & Export
