How to Get Valid WhatsApp Numbers for Marketing

WhatsApp has become a powerful tool for marketers aiming to promote their products or services globally. Its strength lies in direct and fast communication—just having someone’s phone number is enough to start a conversation. There’s no need for friend requests or mutual approval, making WhatsApp highly efficient compared to other platforms.

That’s why many marketers now rely heavily on WhatsApp, especially those looking to grow their audience quickly. With the help of third-party tools, starting a marketing campaign becomes much easier. The only thing you need to begin is a list of phone numbers.

So how do you build this kind of list efficiently? There are two widely used methods:

The first approach is to collect numbers manually through surveys or face-to-face interactions at trade fairs. These contacts are more trustworthy, as users willingly provide their numbers. As a result, most of them are real WhatsApp users, which improves message delivery success rates and avoids wasted efforts.

The second method is to use specialized tools to create phone number lists in bulk. For example, with CrownSoft’s WhatsApp Number Generator, you can generate numbers using formats like country code + digits, or city and region-based number combinations.

After generating the numbers, the built-in filtering function allows you to log into your WhatsApp account and automatically check which of the numbers are actually active on the platform. Beyond just checking for registration, the tool also extracts useful information like profile picture, status text, and estimates of gender, age, and language.

With these insights, you can better segment your audience and run more accurate campaigns. Once verified, the software supports exporting your filtered list, which can then be shared with your team or uploaded into bulk message senders and other automation tools — streamlining the entire process.
