In the process of doing foreign trade marketing, we often get a batch of customer phone numbers, such as collected from WhatsApp group members, WhatsApp number generation, Facebook collection, or phone numbers shared by others. But the biggest problem that follows is: which platforms are these numbers now registered on? Through which channels should we contact them?

WhatsApp is one of the most powerful communication platforms available today, especially for businesses aiming to expand into international markets. With its massive global user base, WhatsApp allows companies to easily reach potential customers, build brand awareness, and engage users through a direct and personal channel.

In today’s globalized market, acquiring qualified leads and executing effective overseas marketing is more complex than ever. With billions of users spread across platforms, simply obtaining contact details isn’t enough—you need tools that help you identify which users are actually aligned with your product or service.

With over 180 countries covered, WhatsApp is one of the world’s most widely used messaging platforms. Marketers love it for its simplicity — you can start a conversation with just a phone number, no friend requests required.But once your contact list starts to grow, things get messy fast. How do you know who’s male or female? Who speaks English or Spanish? Who's still active — and who’s not?

When it comes to WhatsApp marketing, all a marketer needs is the recipient’s phone number to start a conversation. This simplicity has made WhatsApp a preferred platform for direct outreach, prompting marketers to gather large batches of phone numbers before launching any campaign. Today, countless phone number lists are available for purchase, and various number generators make it easy to compile a contact base.

In today’s global marketing environment, many professionals choose different social platforms based on regional user trends to efficiently grow brand visibility. For instance, Facebook sees most of its users in India and the U.S., while X (formerly Twitter) is more popular in the U.S. and Japan. This user distribution influences the selection of marketing channels, which is why many marketers maintain accounts across several platforms to execute campaigns tailored to each target region.
