The change number feature allows you to change the phone number associated with your WhatsApp account on the same or a new phone. Before changing your phone number:
  • Make sure your new phone number can receive SMS or phone calls and has an active cellular connection.
  • Make sure your old phone number is currently registered on WhatsApp on your phone. You can find your registered phone number by opening WhatsApp Settings and tapping your profile photo.

  • VoIP
  • Landlines (Note: Landlines are only accepted on the WhatsApp Business app)
  • Toll-free numbers
  • Paid premium numbers
  • Universal access numbers (UAN)
