Homepage of NumRadar

NumRadar is a WhatsApp number validation service that tells you whether a phone number is registered on WhatsApp. It offers multiple ways to access the service: a REST API for developers, bulk CSV file uploads for processing multiple numbers at once, an MCP server for integration with AI agents, and a Chrome extension for quick lookups. Registered and unregistered results both count toward your monthly allowance, while failed lookups do not. The service operates on a paid subscription model with plans starting at €9 per month.
