NumRadar - WA Numbers Verification and Bulk Checker

Overview

Check if phone numbers are on WhatsApp. Find numbers on webpages, save leads, and review results in a side panel.

Check whether phone numbers are registered on WhatsApp while you browse. NumRadar keeps the page and your results side by side. Find phone numbers on a page. Hover over an underlined number for Check, Copy and Save. Review results in Chrome's side panel, keep a local inbox, or check multiple numbers with the bulk tools. A NumRadar account with an active paid plan and an API key is required for checks. Checks use your plan’s validation allowance or available prepaid balance. Installing the extension does not include free validations. You do not need to connect your WhatsApp account to this extension. Detection runs locally on sites you enable. Checking sends the selected number to NumRadar. Saved numbers remain on this device until you delete them or uninstall. Copy and Save do not use validations. NumRadar is independent and is not affiliated with or endorsed by WhatsApp or Meta. A registration result does not establish ownership, permission to message, recent activity or future message delivery.
