How to Find and Change Your WhatsApp Number (Android and iPhone)

1. Find Your WhatsApp Number on Android

Step 1: Launch WhatsApp and tap the three-dot menu. Select Settings from here.

Step 2: Tap your name at the top with your profile picture. Here, you’ll see your name and registered mobile number in WhatsApp.

To change your name or about info: Click the edit icon next to it. For example, tap your name, and your keyboard app should launch automatically. Enter your desired name and tap on Save.

To change your WhatsApp number: Go to Settings → Accounts → select Change number.

Note: When you switch your WhatsApp number, you’ll be migrating your account, along with all its data, to this new number. The number should be active, and the SIM should be on your smartphone.

In the next window, tap Next. WhatsApp will detect your country code automatically but check it for errors, if any. Enter your current WhatsApp number first and then, enter the new WhatsApp number. Tap on Next.

You will now receive an OTP on your new WhatsApp number to verify ownership. If the app can’t detect the OTP automatically, enter it manually and continue. You will now see three options to notify your contacts of your new WhatsApp number.

Note: Your chat history will not be deleted if you use the same phone to change your WhatsApp number. That is possible on a dual SIM Android phone where you are changing the number, not the smartphone itself. If you are changing phones, too, take a backup.

2. Find My WhatsApp Number on iOS and Change It

Android and iOS smartphones function differently, but WhatsApp remains essentially the same. Here is a complete breakdown of how to find and change your user name and number on WhatsApp.

Open WhatsApp on your iPhone or iPad. Under Settings, tap on your name next to the profile pic. Your name and mobile number will be listed here.

To change the name: Tap it and your default or chosen keyboard app will launch automatically upon selecting the name. Notably, you can also change your profile picture (tap Edit) and About from this section.

To change your mobile number: Go to Settings > select Account. Here, tap Change number.

Next, you will see a notification screen where they will explain what happens if you change your WhatsApp number. Tap Next when ready → enter your old/current WhatsApp mobile number and then your new mobile number.

Once done, tap Next to proceed. An OTP will be sent to the new number to verify the process. Enter the OTP if the SIM is on a different iPhone or not detected automatically.

Depending on your internet speed, the transfer process may take some time. You should now see all your WhatsApp data on the new number. Like in Android, you will see three options to notify your contacts about your mobile number change. Choose one that meets your needs.
