How to Filter Valid WhatsApp Numbers Before Messaging

WhatsApp allows marketers to reach potential clients directly using just a phone number. Because of this, it’s common for marketers to collect large batches of numbers before launching any campaign — whether by buying lists or using number generation tools that are widely available today.

However, having a list of numbers doesn’t guarantee successful outreach. A key issue is that it’s difficult to know in advance which numbers are actually active on WhatsApp. Some users may have deactivated their accounts or changed numbers, and sending messages to unregistered users not only wastes time but also reduces the overall effectiveness of the campaign.

This challenge, though, is easy to solve. By using the CrownSoft WhatsApp Filtering Tool, marketers can quickly identify which numbers are currently active on the platform.

The process is simple. Just upload your list of phone numbers into the software, log into your WhatsApp account, and the system will begin scanning. It automatically detects which contacts are registered, saving you hours of manual checking.

Beyond just confirming registration, the tool offers deeper filtering capabilities. For each active account, it retrieves profile details such as profile photo and status message. It can even analyze these to estimate the user’s language, gender, and age, offering a layer of valuable insight for targeting.

Once filtered, you can export the data based on criteria like gender, age, language, or registration status. This makes it easy to pass the data to your team or integrate it into other marketing software — helping you build a cleaner, more focused list for WhatsApp outreach.
