Step 1: Create a Google Voice Phone Number.
Go to Google Voice to select a phone number.
Search for phone numbers that contain certain words, or numbers, for easy sharing. For example, if your last name is "Jones" you could search for a phone number that contains "Jones" such as 1-555-55-JONES (1-555-555-6637).
Note: Numbers are subject to availability.
Step 3 - Verify your Phone Number.
After you link your personal phone to your account, you will be given an automated verification code. Click on "Call Me Now" and Google's automated service will immediately call your phone. Then, you will be prompted to enter the verification code.
Afterwards, you will also have a chance to set up your voice mail and name greeting.
