How to Change the Voicemail Number on an iPhone

By Art Corvelay

The iPhone has a voicemail feature known as visual voicemail. This feature allows you to view a list of messages on your phone and select a message to listen to. In the background, however, your iPhone dials a number to retrieve or access your voicemail. You can change the 9-digit voicemail number from the default number that is assigned to the iPhone.

Step 1

Turn on your iPhone by holding down the "Power" button at the top of the iPhone.

Step 2

Tap the "Phone" icon in the dock of your iPhone. This is a green icon with an image of a phone headset on it.

Step 3

Tap the "Keypad" in the bottom dock of the Phone menu.

Step 4

Enter the following: "*5005*86*123456789#." You can substitute the "123456789" with any 9-digit number you want to assign to your voicemail.

Step 5

Tap the "Call" button and the number is assigned to your iPhone.

Step 6

Dial the 9-digit number you assigned to your iPhone's voicemail and tap "Call" to make sure you have properly assigned a number to your voicemail. Your iPhone will display "Voicemail" when calling the number.
