WhatsApp number verification -- batch screening and filtering

WhatsApp is the most commonly used customer acquisition platform for foreign trade enterprises engaging in international marketing. Similar to WeChat in China, WhatsApp is widely used for communication, boasting over 2.3 billion monthly active users globally, making it a primary messaging tool in many countries.

To acquire customers on WhatsApp, the first step is to register a WhatsApp account. Since WhatsApp operates as an instant messaging tool, all actions are based on having a WhatsApp account. Whether you're sending bulk messages or adding friends, logging into a WhatsApp account is essential.

WhatsApp registration is tied to phone numbers, with one WhatsApp account per phone number. Obtaining a WhatsApp account essentially means acquiring a user's phone number. However, phone numbers are sensitive data, and different countries have varying country codes and number formats, increasing the difficulty of customer acquisition.

To address this, quickly obtaining phone numbers associated with active WhatsApp accounts requires using third-party WhatsApp marketing software: WhatsApp screening.

WhatsApp screening serves three purposes:

Generates phone numbers for various countries based on country codes and number formats.

Verifies if generated phone numbers have active WhatsApp accounts, screening for WhatsApp profile pictures, gender, age, and more.

Imports phone numbers in bulk to verify if they have active WhatsApp accounts.
