WAFilter is a Chrome extension developed by the WhatsABot team. It is a WhatsApp number checker, filter, and validator that allows users to instantly filter and validate WhatsApp phone numbers. This extension is particularly useful for marketing and sales companies that need to filter bulk lists of contacts for any country or import from a CSV file.

With WAFilter, users can validate bulk lists of numbers from any country with 100% accuracy and high-speed validation. The extension also offers a phone number generator and the ability to filter numbers imported from a CSV file. Users can filter numbers country-wise and track all checking progress, which is saved to history. Additionally, they can download the success/failure list to a CSV file.

WAFilter prioritizes data privacy, as no email address is required to log in and no data is shared with third parties. All data is processed locally on the user's computer and does not pass through the web server.

Please note that WAFilter is an independent project and is not related to WhatsApp Inc., the trademark owner of WhatsApp™.
