How to check if a phone number is On WhatsApp?

Here is the thing: it is a struggle to check if a number is on WhatsApp or not. You have to add the mobile number first as a contact before you can verify if the number is WhatsApp-registered or not. 

If the “Invite” button appeared after you added the contact number, it means that the number is not yet registered on WhatsApp. Check the full steps here.

But did you know, there is an easier way to check this?

In this article, we will show you the step-by-step guide in using the WARocket’s Download Report feature, so you can check if the number is on WhatsApp or not without adding them on your contact list.

And of course, you can also download a report about the message sending activities in WhatsApp.

The Download Report feature

With the WARocket’s Download Report feature, you can have a glimpse of your sending activities in WhatsApp including:

  • The phone numbers of the people you’ve sent the message to
  • The status of the message sending activities
  • The Time and Date of the activities
This screenshot shows how the export file looks like.

Now the status comes in 2 possible results:

  • SENT. It means that the message was successfully sent
  • NOT EXIST. It means that the number you are trying to reach is not a WhatsApp registered number

By checking the status on the downloaded report, you can now check if the number is on WhatsApp or not.

How To Use the Download Report Feature

1. Go to and install the Chrome extension to your browser.
