With number portability, Google will allow users to continue using their existing number with the features that Google Voice provides users with. Users will no longer have to make use of a new number which was the case earlier.
Today, we’re excited to announce that Number Porting is available for all existing Google Voice users. This means you can make the mobile number you’ve always used your Google Voice number, so it can ring any phone you wantâ€”or even your computer.
The number porting will come in handy for people who have used a single number for a long time and do not want to forgo it just to use Google Voice. To port your number to Google Voice, login to your account and visit the settings page. On this page click on the "Change / Port" link to port your number to Google Voice. Porting your number is quite handy, but it will come at a one time cost of $20. The process itself will be completed within 24 hours too.
Once you have ported your number to Google Voice, your mobile service plan will be cancelled and you will have to follow a series of steps to continue making calls through Google Voice. This Google Voice Help Center article has detailed steps on how number porting works along with tips to make the switching process easier.
Number Porting will initially be available for existing customers, with support for new customers in near future. You can watch a video about how Number porting will work below. Click here if you can’t see it.
