You can change your Google Voice number, but only once every 30 days, and the process takes a few minutes from your Google Voice settings

Google Voice lets you keep a single phone number across devices and forward calls to your real phone. If you want a different number — because you've moved, changed jobs, or straightforward want a fresh start — you can swap it out. The catch: Google limits you to one change per 30 days, and you lose your old number permanently once you change it.

The change happens inside your Google Voice account, not through a phone call or support ticket. You'll need access to the email address tied to your Google Voice account, and you should have a backup phone number where Google can send a verification code.

Key Takeaways

  • You can change your Google Voice number once every 30 days by going to Settings in the Google Voice app or website and selecting "Change number" under the phone number section.
  • Google will show you available numbers in your area code or a code you choose, and you pick the one you want before confirming the change.
  • Your old number disappears permanently after you change it, so anyone trying to reach that number will get a message that it's no longer in service.
  • You must wait 30 days between changes, so choose carefully — changing back to your old number is not possible once the 30-day window closes.
  • If you have forwarding set up to other phones, those settings stay in place after you change your number, but you should verify they still work.

How to change your number in Google Voice

Open Google Voice on the web at voice.google.com or use the Google Voice app on your phone. Sign in with the Google account that owns your Voice number.

On the web version, click the gear icon in the top right corner and select Settings. On the app, tap the menu icon (three horizontal lines) and go to Settings. Look for the section showing your current phone number — it's usually near the top under "Account" or "Phone number".

Click or tap Change number. Google will ask you to confirm that you want to proceed. It will remind you that you can only change once every 30 days and that your old number will be released.

Google then shows you a list of available numbers. You can search by area code if you want a number from a specific region. Select the number you want and click Next. Google will send a verification code to your backup phone number or email address. Enter that code to confirm the change.

Once you confirm, the change is when ready. Your new number is active right away, and your old number stops working.

What happens to your old number and your contacts

Your old Google Voice number becomes inactive as soon as you change it. Anyone who tries to call or text that number will hear a message saying the number is no longer in service. Google does not reassign your old number to someone else right away — there's typically a waiting period — but you should not count on being able to get it back.

Your contacts do not automatically get notified of the change. You'll need to tell people your new number yourself. If you use Google Voice to send text messages, those conversations stay in your account, but they're tied to your old number in the chat history. New messages from your contacts will come through your new number.

If you have voicemail greetings or custom settings tied to your old number, those do not carry over. You may want to re-record a greeting or adjust settings after the change.

Forwarding and voicemail after you change your number

Any phone numbers you set up to forward calls to — your mobile phone, home phone, work phone — remain active after you change your Google Voice number. Calls to your new number will still ring those phones. However, you should test the forwarding to make sure it's working, because sometimes the connection can drop during account changes.

To check your forwarding settings, go back to Settings and look for Forwarding options or Linked numbers. Make sure the phones you want to ring are still listed there. If one is missing, click Add another phone and enter the number again.

Voicemail transcripts and recordings from your old number stay in your Google Voice inbox. You can listen to them anytime, but they're labeled with your old number in the message details.

The 30-day waiting period between changes

Google enforces a strict 30-day rule: once you change your number, you cannot change it again for at least 30 days. This is a hard limit, not a guideline. If you change your number on January 15th, the earliest you can change again is February 14th.

This rule exists to prevent abuse and to give you time to make sure your new number is working. It also means you should think through your choice before you confirm. If you realize when ready after changing that you picked the wrong number, you have to wait a month to switch again.

If you're unsure about a number before you commit, you can browse available numbers without changing. Just don't click the final confirmation button until you're certain.

Why you might want to change your Google Voice number

People change their Google Voice number for different reasons. You might move to a new city and want a local area code. You might have shared your number with someone you no longer want to hear from and prefer a fresh start. You might have used Google Voice for a project that ended and want to separate it from your personal life.

If you're changing because you're concerned about privacy — for example, your number has been shared in a data breach or you've been getting unwanted calls — changing the number does reset things. Your new number won't have the history of spam or harassment attached to it. However, if you continue to use the same email address and forwarding setup, someone determined could still connect the old and new numbers to you.

If privacy is your main concern, consider whether you also want to change your Google account email or adjust who has access to your forwarding phone numbers.

What to do if you cannot change your number

If you see a message saying you cannot change your number, the most common reason is that you've already changed it within the last 30 days. Check when you last made a change by going to Settings and looking for a note about when you can change next.

Another reason the option might be grayed out is if your Google Voice account is not fully set up. You need an active, verified Google Voice number to change it. If you just created your account, wait a few hours for it to fully set up.

If you're locked out of your Google account or cannot access the email tied to your Voice number, you'll need to recover your account first. Go to accounts.google.com/signin/recovery and follow the steps to regain access.

If none of these explore and the option is still unavailable, contact Google Voice support through the help menu in your settings. Explain that you want to change your number and cannot see the option.

Frequently Asked Questions

Can I get my old Google Voice number back after I change it?

No. Once you change your number, your old number is released and you cannot reclaim it. Even if the number becomes available again later, Google does not prioritize returning it to you. Treat the change as permanent.

Do I lose my voicemail and text message history when I change my number?

No. All your voicemail recordings, transcripts, and text conversations stay in your Google Voice inbox. They're labeled with the number they came from, but the messages themselves don't disappear.

Will my contacts automatically know my new Google Voice number?

No. Google does not send notifications to your contacts. You need to tell them your new number yourself. You can send a text or email to let people know you've switched.

What if I change my number and then realize I made a mistake?

You'll have to wait 30 days before you can change again. If you need a different number sooner, your only option is to create a new Google Voice account with a new email address, but that means starting over with a different number and losing access to your current account.

Does changing my Google Voice number affect my Gmail or other Google services?

No. Your Google Voice number is separate from your Gmail account and other Google services. Changing your Voice number does not change your email address or affect anything else tied to your Google account.
