How to Enable Google Voice With Your Existing Number

One of the more annoying things about the Google Voice service, since its release, has been the inability to use an existing phone number with the service.  At sign-up (if you were lucky enough to get an invite from Google or a Friend) you had to create a new Google Voice number which you would then need to advertise to your friends and family.

Even Google recognized how lame this was and announced a half-baked idea about providing new business/contact cards to help spread the word.  Yeah, I know…Sounds like the Windows 7 Launch Parties.

Anyway, Google knew that in order for the service to be more than just a cool gadget people played with but didn’t actually use Google would need to remove this key roadblock… and that that’s just what they did tonight with a new upgrade to Google Voice.

Google-Voice Feature Comparison Vs. Non-Google Number Effective immediately, Google voice will now allow you to leverage your existing mobile number to take advantage of select features of the service.  The list of features available include:

  • Google Voicemail
  • Voicemail Transcription
  • Custom Voicemail Greetings
  • International Calling
  • Mobile Apps


More features can be found here for “Google Voice Feature w/Google Number Vs. Non-Google Number.”  Also, please note that only the following carriers are officially supported at this time: Alltel, AT&T, Cricket Wireless, MetroPCS, Sprint, T-Mobile, US Cellular, and Verizon.

Obviously, the largest feature here is the integration of Google Voicemail, Transcription, and Custom Voicemail Greetings.  Here’s a quick Voicemail from Google Voice:

Enable Google Voice Integration w/Existing Mobile Phone Number

1. Log in to Google Voice, click Settings then click Activate Google voicemail for this phone.

Note: The option will only be available for Mobile Numbers.

I’ve not enabled the service on my iPhone yet but since it appears simple to disable, I’m sure I’ll play around with it tomorrow. What about you? Have you tried it out yet? Would love to hear your feedback!

    Hi Mrgroove.

    What happens when you use an existing number but don't like it? Can you move back to your google voice number

  9. MrGroove

    Yes. When you goto enable an existing # onto Google Voice it will notify you that you can disable it at anytime. I highlighted this in Yellow the Screenshot I posted in Step #1 Above.
