Enabling this feature will send a notification to all the contacts with the number you are changing the number to. This update has been added to the WhatsApp Beta app with version number 2.18.97. This “Change number feature” came to the new beta app of WhatsApp recently which enables the user to change the number easily on WhatsApp. Changing the number will also migrate the data to the new number the user is changing too. The notification feature will ask the user to notify the contacts for number change with three options. It will ask you if the notification needs to be sent to All contacts, Contacts I have chat with and custom. In Custom option, you have to choose the contacts by yourself to which you need to notify about the number change. This feature has been found by WABetaInfo with a screenshot of the options. To check if you got this update on your WhatsApp Beta, go to WhatsApp Settings > Account > Change number. Now enter the new number which you need to change the number and tap Next. After tapping on Next, you will see the Notify contacts option where you will see all the three options which we talked about earlier.
