What is the Significance of WhatsApp Number Detection and How to Do It?

WhatsApp is currently one of the most commonly used communication and social software worldwide. Millions of people use this software for communication daily, with over 3 billion monthly active users. It is very popular, and many marketers also choose to use it for marketing purposes. However, whether for personal social use or business marketing, many times we need to know whether a number is registered on WhatsApp. Marketers generally refer to this as number detection.

The significance of number detection mainly lies in three aspects. First, it improves communication efficiency. If you want to contact someone, knowing in advance whether the other party has registered on WhatsApp and whether they can receive messages helps prevent wasting time waiting for replies from invalid contacts. Second, it saves costs. For marketers, confirming which numbers are valid before sending messages in bulk avoids wasting resources on invalid numbers and reduces the risk of accounts being flagged or blocked.

So how should we perform WhatsApp number detection? The most common solution is to use WhatsApp’s built-in functions. We just click “New Chat” in WhatsApp and enter the number (remember to use the international format). If the number is registered, it will automatically appear as a contact; if not, it will show “contact not found.” This method is the most direct and also low-cost.

Another common method can also be done directly using WhatsApp. We can save the numbers to the contacts list, then refresh the contact list in WhatsApp. If the number is registered, it will appear; if not, it will not show.

These two methods are suitable for situations with a small number of contacts. However, if you want to market to multiple contact lists, we need to use some third-party tools, such as Crownsoft WhatsApp Number Detection Software. It is a professional tool that helps us solve this problem. In this software, we only need to import the phone number list and log in to the relevant account, and the software can quickly detect which phone numbers are registered on WhatsApp.

Unlike other methods, Crownsoft WhatsApp Number Detection Software can perform in-depth detection of user information, such as user signature, profile picture, gender (recognized), age (recognized), and signature language (recognized). The software can categorize and export this information into multiple file formats, helping you select customers more efficiently for WhatsApp marketing.
