Porting your personal Google Voice number

To port your personal Google Voice number: 

1. On your computer, open Google Voice.
2. You'll be prompted to pick a new number, but your ported number will soon replace it, so it won’t matter what that number is.
3. At the top left, click Menu  > Legacy Google Voice. Google Voice will look different, but you're in the right place.
4. At the top right, click Settings  > Settings.
5. Click the "Phones" tab.
6. Next to your current number, click Change / Port.
7. Select I want to use my mobile number. Follow the on-screen instructions to set up your new number.
