How to Change Your Phone Number on iMessage

This wikiHow teaches you how to prompt your iPhone's number to appear in iMessage if you have a new number, as well as how to select an email address as the point from which to send your messages instead of using your phone number....

Method 1 of 2:

Resetting Your Phone Number

Understand when to use this method. Resetting your iPhone's phone number is only necessary when the phone number displayed in the iMessages section is incorrect. If your iPhone is already sending iMessages from your phone number, skip this method.^[1]
1. You can try setting an email address as the place from which iMessages send if you don't want other people to see your phone number for iMessages.
Open your iPhone's

Settings. Tap the Settings app icon, which resembles a grey box with gears on it.
Scroll down and tap

Messages. It's about halfway down the Settings page.
Tap the green "iMessage" switch

. You'll find this at the top of the page. Doing so will disable iMessages on your iPhone for the time being.
Turn off your iPhone and wait for 10 minutes. Press and hold your iPhone's Power button on the right side of the housing, then swipe right the Power

switch on the "slide to power off" track. Once your iPhone turns off, wait for at least 10 minutes before proceeding.
1. You can also press the Power button 5 times in order to bring up the power menu.
Turn back on your iPhone. Once 10 minutes have passed, press and hold your iPhone's Power button until you see the Apple logo appear on-screen, then release the button and wait for the iPhone to turn back on.
1. If you use a passcode, you'll need to enter it before you can proceed.
Re-enable iMessage. Open

Settings, tap Messages, tap the white "iMessage" switch

, and then wait for the "Waiting for activation..." message to disappear from below the "iMessage" section.
Check your iPhone's current number. Once iMessage is active, you can check your current iMessage phone number by tapping Send & Receive at the bottom of the screen and ensuring that the phone number at the top is your current number.
1. If you still don't see your iPhone's number here, repeat this method. Make sure you wait for at least 10 minutes before turning back on your iPhone.

Method 2 of 2:

Changing the iMessage Send Location

Open your iPhone's

Settings. Tap the Settings app icon, which resembles a set of gears on a grey background.
Scroll down and tap

Messages. It's near the middle of the Settings page.
Tap Send & Receive. You'll see the option at the bottom of the screen.
1. Depending on the size of your iPhone's screen, you may first have to scroll down to see this option.
Review the "START NEW CONVERSATIONS FROM" section. This section is near the bottom of the page; it lists each address from which you can send an iMessage.^[2]
1. At minimum, you will see one email address and one phone number here. The email address is your Apple ID email address.
Select an email address. Tap the email address from which you want to send iMessages. This will ensure that, when you send an iMessage, the recipient of your iMessage will receive it from your email address and not your phone number.
1. If the person on the other end of the message has your phone number in their contacts or can't receive iMessages, this method won't mask your number.
