Verify Customer Numbers Across WhatsApp, Facebook, Instagram, Telegram

In foreign trade promotion and marketing, social media marketing has become a very efficient way to acquire customers. Many companies and marketers use platforms such as WhatsApp, Facebook, Instagram, and Telegram to find potential clients for marketing. Common actions include adding contacts as friends to send messages or directly messaging them using their phone numbers.

Although marketing is simple on these platforms, in practice we often encounter common problems. For example, not all numbers in our lists are necessarily registered on these social platforms. If we import a list directly for promotion and send messages to numbers not registered on the platforms, it not only wastes marketing resources but also reduces overall marketing efficiency. This problem needs to be solved—how can foreign trade professionals quickly check whether numbers are registered on social media platforms?

The traditional method is to manually try adding friends or sending messages. If a response is received, the number is registered on the platform. Although this method works, it is very time-consuming and labor-intensive, especially when the list contains many numbers.

A more efficient and practical method is to use third-party auxiliary tools, such as CrownSoft Various Account Filters Software. We only need to import the number list and log in with the required accounts, and the software can easily help us filter whether numbers are registered.

In addition, besides detecting account registration, some software can provide more detailed user information. For example, on WhatsApp, we can see profile pictures, statuses, languages (identified), and even gender (identified) and age (identified). On Telegram, we can also get users’ active times. This data helps foreign trade personnel quickly identify which numbers are truly active customers and which fit the marketing target, enabling more precise marketing.
