(image credit: Small Biz Trends) When you port a number to Google Voice, you are transferring from your old service to Google Voice’s.

That seems easy enough. When you do port a mobile number to google voice however, your new Google Voice number isn’t so straightforward to use. Here’s why you should and should not port a mobile number to Google Voice.


Option 2: Port your Google Voice number out to a mobile phone service

To port your number out of Google Voice, unlock the number. Then, let your mobile service provider know you want to port a number to their service. They do the rest.

Unlocking your Google Voice number costs $3, but it’s free if your number was originally ported in from a mobile service provider.

  1. On your computer, go to the Google Voice unlock page.
  2. Point to the Google Voice number you want to port, and click Unlock my number.
  3. Click Continue.
  4. Pay with your Google Account. You’ll get your receipt by email.
  5. Ask your mobile service provider to port your number to their service. Note: If your mobile service provider asks for your account number and PIN, provide your ten-digit Google Voice phone number and the PIN you use to access your Google Voice voicemail.

Note: Without a phone number, your account will change to Google Voice Lite.

Lock your number again

If you decide not to port your Google Voice number, you can lock it again. On your computer, go to the Google Voice unlock page. Under your Google Voice number, click Relock my number. Click Continue. You’ll see a status page where your number is marked as “Locked.” You can always unlock your number again for free.

“Can’t relock your number” error

If a service provider, like Verizon or AT&T, has already let us know about the port you asked for, you can’t relock your phone number.

Checking your number with Google Voice first

Before you do anything, you should head over to the Google Voice check number page, and enter your phone number. This will help determine whether you can port your phone number to Google Voice. (Yes, even if it’s your landline.) 

Some area codes — Hawaii (area code 808) and Alaska (area code 907) — are not supported by Google Voice. So you should take this step first before wasting your time or money. 

The answer you get is kind of the Zoltar of your landline’s future. 

If the message says, “This number appears to be from an area we don’t currently support,” then you’re out of luck. You won’t be able to port your number to Google Voice. 

But if your message says, “We don’t currently support porting from your carrier” then that’s good! It means you live in a supported area that supports porting your landline to a mobile carrier, and eventually Google Voice. 

Keep Your Current Phone Number (Port A Number to Google Voice)

Planning to change your mobile plan and found a better deal with a competitor? This happens more often than you think. Your monthly bill will be a little cheaper than last month and your service is still just as good. But what about the phone number? You’ve been using the same number for several years. It’s the one all of your friends and family have saved in their phone. Do you hold off?

If you want to get a new number but still want to keep your old one, Google Voice can be the answer to your prayers. It offers individuals the chance to port their existing number over to their service for a one-time fee of $20. So not only will you get the new number with your new service, but you can also maintain your existing number and have all calls forwarded from that number to the new one. How awesome is that?

You’ll need to know that when you port a number to Google Voice, you can’t use the Google Voice app to send text messages–it requires a data connection over Wi-Fi or a mobile network. But you can, however, have Google Voice forward SMS texts to your new number. When replying to the incoming texts using your regular messaging app, the messages will appear to come from your new Google Voice number.

This is the same way that phone calls will work. With call-forwarding turned on, you can make and receive calls from your Google Voice number, even without a data connection. This should go without saying but you will need two phone numbers in order to port a number to Google Voice. This is your existing number where the calls and texts are received, and the new number to where they will be forwarded.

Your existing number will be the one ported over and must remain active at the time you begin the process. So DO NOT cancel your account before doing so. The new number can be one provided to you by your current carrier or a new carrier. Your second number can even be one from Google Voice. If you are switching carriers, once you start a new account with them and port your number over to Google Voice, Google will cancel your previous carrier account on your behalf. For a new number while remaining with the same carrier, after the number is added to Google Voice, Google will cancel your old number.

It’s very important that you don’t attempt to make such a change while still in the middle of a contract. Porting your number over has the potential to carry with it an Early Termination Fee (ETF) if canceled early. To be sure, contact the customer support of your current carrier and inform them of what your plans are before you cancel. They’ll be able to make a note on your account to not charge you an ETF when you finally cancel.

Calls and text messages to both numbers will reach you so long as call-forwarding has been turned on. However, outbound calls and texts will only be sent from your primary Google Voice number. Google Voice does allow you to swap which number you want as your primary, at any time you’d like.

To port a number over to your Google Voice account:

  1. Open Google Voice in your browser and log in.
    • You must be within 90 days of the cancelation process in order to port the number over. Any later and the number will be unavailable.
  2. You’ll find Settings at the top right, so go ahead and click it.
  3. Click ‘Account‘ then click on ‘Change‘ under your phone number just as we did above.
  4. Click over to the ‘Phones‘ tab.
  5. Click ‘Change/Port‘ then click ‘I want to use my mobile number.’
  6. Type in your phone number and select ‘Check for available options.’Assuming your number is available for porting you
  7. Assuming your number is available for porting you will see a blue ‘Port your number‘ hyperlink at the bottom of the pop-up window. Click it.Check the boxes that appear confirming you accept
  8. Check the boxes that appear confirming you accept the conditions of porting.On the next screen, input all of your current acco
  9. On the next screen, input all of your current account information.
  10. Once the transaction has been completed, the expiration date next to your original Google Voice number will now disappear. It now belongs to you until you cancel/delete it yourself.

Google Voice can only accept port-ins from mobile phone carriers like AT&T, Verizon and T-mobile.

1. Visit the Google Voice homepage and then navigate to Legacy Google Voice via the menu on the upper left-hand corner of your screen. 

2. Click Settings (the icon that looks like a cog) and then Settings again. Then, click the Phones tab. 

3. Next to your current Google Voice number, click Change/Port, then select I want to use my mobile number

4. Follow the instructions to proceed with setting up your new number and complete payment. You’ll then need to set up phones to receive calls once the process is complete. Your number can take between 48 and 96 hours to port.
