If you need to change your phone number on WhatsApp, it helps to have your old phone handy. You can change your WhatsApp number if you are using the same phone or if you have a new phone and still have access to the old one. If you no longer have access to your old phone, you will need to set up a completely new WhatsApp account. When you change your number, you will no longer be able to log into your account using your old number.




Having a new phone often means transferring all your data to the new one. If you have WhatsApp, you will need to update your phone number so that you can log into your account with your new phone. Here's what happens when you change your WhatsApp number and how to do it.

What happens when you change your number on WhatsApp

There are a few things that happen when you change your number on WhatsApp:

  • Your profile, settings and WhatsApp groups will be moved to your new phone number.
  • You will not be able to log into your WhatsApp account on your old phone.
  • The account associated with your old phone number will be deleted, so your contacts via the app will no longer see it in their contacts.

Due to all these consequences, it is a good idea to inform your WhatsApp contacts of your new phone number. That way, they can continue to connect with you when you make the change.
