Porting a Google Voice number means one of two things, and the steps differ. You can bring a mobile number into Google Voice, or you can move your Google Voice number out to another phone service. Moving out is what most small businesses need. The short version: unlock the number in Google Voice, give your new provider exact account details, and keep Google Voice active until the port finishes.
This guide covers both directions, what to prepare, how long it takes, and why ports fail. If you are porting out to run a business line, we also show how we handle it at Talkroute.
TL;DR
- Porting in: Google Voice generally accepts mobile numbers, not landlines or most VoIP numbers. Start in Google Voice under Settings, then Account, then Port a number.
- Porting out: Unlock the number in your Google Voice settings first. Your new provider then submits the request for you. You do not contact Google to start it.
- Details must match: Your Google Voice number acts as the account number, and your voicemail PIN acts as the PIN. A mismatch in name or address is the most common reason for rejection.
- Timing: The FCC says simple ports between wireless providers are required to be processed in one business day. Other port types can take longer.
- Do not cancel early: Keep your Google Voice account open until the new service confirms the number is live.

Two directions, two different jobs
Search results for this topic mix up two situations, so decide which one you are in.
Porting a number into Google Voice. You have a mobile number with a carrier and want it to live inside Google Voice. Some people do this to keep a number while living abroad or switching carriers. It suits personal use.
Porting a Google Voice number out. You built your business reputation on a Google Voice number. Customers have it on your website, invoices, and Google Business listing. Now you need shared access for a team, auto-attendant menus, call routing, or business texting. You want the same number on a business phone system.
The second case is the one where waiting costs you money. Every month the number stays in a consumer app is a month without call routing, team inboxes, or after-hours handling. Much of this guide therefore focuses on moving out.
Porting a number into Google Voice
If you want to bring a number in, here is the usual path.
What the number must be
Google Voice generally accepts mobile (wireless) numbers from US carriers. Landline numbers and most VoIP numbers are not accepted for direct porting. Check the current eligibility rules on Google’s own help pages before you start, because the carrier list and fees are Google’s to change.
Before you start, confirm:
- The number is active and in service with your current carrier, in your name or your business’s name.
- You have a working US number to verify your Google Voice account.
- You know your account number and transfer PIN from the current carrier. Ask the carrier for these. They are not the same as your login password.
- The billing name and address match the carrier’s records exactly.
- You have a payment method ready, because Google charges a fee to port a number in. Confirm the amount on Google’s page when you begin.
The steps
- Open Google Voice and sign in, or create your account.
- Go to Settings, then Account, then Port a number, then Get started.
- Enter the number and answer the eligibility check.
- Provide the carrier account details and pay the fee.
- Wait for confirmation. Do not cancel the old carrier plan until the number arrives in Google Voice.
The last point matters. If you cancel first, the old carrier may release the number and you may lose it for good.
Porting your Google Voice number out to a business phone service
This is the direction most small business owners ask about. The process is straightforward when you prepare.
Step 1: Unlock the number
Google Voice requires you to unlock a number before another provider can take it. In your Google Voice account, open Settings, then Account, and look for the option to unlock the number to port it. Google may charge a one-time unlock fee, and it may waive that fee for numbers you originally ported in from a mobile carrier. Check the amount on screen before you pay.
Only the account owner can do this. If a former employee set up the Google Voice account, regain access before anything else. Ports cannot start without it.
Step 2: Gather exact details
Your new provider will ask for the information below. Google Voice does not issue a traditional account number, so the fields work a little differently.
| Field | What to enter |
|---|---|
| Number to port | Your 10-digit Google Voice number |
| Account number | The same 10-digit Google Voice number, no dashes or spaces |
| PIN | Your Google Voice voicemail PIN, not your Google password |
| Account name | The name on the Google Voice account, spelled as Google has it |
| Service address | The billing address on the account, formatted exactly as on file |
Character-for-character matching counts. If Google has “Street” and you enter “St.”, some carriers reject the request. Copy the details exactly as they appear on your account.
Step 3: Start the port with the new provider
The provider you are moving to submits the request to the network behind Google Voice. You do not start it from Google’s side. At Talkroute, our team walks you through it, and you can read the full process on our page about how to port a number from Google Voice to Talkroute or the shorter overview at port your Google Voice number to Talkroute.
Step 4: Keep Google Voice active
Leave the Google Voice account open until your new provider confirms the number is active. Deleting the account or the number mid-port is the fastest way to turn a clean move into a lost number.
Step 5: Test everything
When the port completes, call the number from a different phone, send a text, and leave a voicemail. Confirm your greeting, hours, and routing are working. Then you can close the Google Voice account.
How long does a port take, and what does it cost?
Timing depends on the type of port. The FCC states that simple ports between wireless providers are required to be processed in one business day, while wireline-to-wireless transitions may take a few days. Because Google Voice numbers are handled through a different pathway than a standard mobile carrier, plan for a window of a few days and ask your new provider for its estimate.
On cost, there are two possible charges: Google’s fee, which applies on its side (the unlock fee when leaving, a porting fee when entering), and any fee from the new provider. Your own fees are the ones you control. Talkroute lists its plans at our pricing page. For reference, our Basic plan is $19 per month, Plus is $39 per month, and Pro is $59 per month. Check the page for what each includes and for any one-time fees tied to local number registration.
One helpful rule from the FCC: old companies cannot refuse to port a number based on outstanding balances or early termination fees. That rule speaks about carriers you are leaving. It does not remove the need for correct account details.
What happens to calls and texts during the port
Until the port completes, your number keeps working where it is. Calls and texts still reach Google Voice. When the switch happens, they route to the new service, usually within minutes of the scheduled completion.
A few practical points:
- Do not change anything at Google mid-port. Updating the name, address, or number settings can trigger a mismatch.
- Voicemail does not move. Save any voicemail you want to keep, including transcripts, before the port completes.
- Text history stays behind. Export or screenshot conversations you need for records.
- Forwarding is a bridge. If you want a gentle transition, you can forward calls from Google Voice to your new business number while the port is pending. Our support team explains forwarding calls from a Google Voice number to Talkroute.
- Emergency calling. The FCC warns that during some wireline-to-wireless ports there may be a period when two telephones share one number, which can affect 911 location and callback services. Keep a working mobile phone nearby for 911 until the port is confirmed.
After the port, outbound calling is the next thing to check. If your team makes calls to prospects, local presence dialing lets calls show an area code that looks familiar to the person answering, which can help calls get picked up.
Why a port fails, and how to fix it
Most rejections come down to a small number of causes. Here they are in the order we see them.
- Name mismatch. The name on the request differs from the Google account name. Fix: copy it exactly from your Google Voice settings.
- Address mismatch. Abbreviations, suite numbers, and ZIP codes cause trouble. Fix: use the exact address on file. If the provider requires a formal service address that Google Voice does not show, ask the provider what it will accept.
- Wrong PIN. People enter their Google password or a carrier PIN. Fix: use your Google Voice voicemail PIN. If you forgot it, reset it in your settings first.
- Number still locked. The unlock step was skipped or did not finish. Fix: confirm the number shows as unlocked, then resubmit.
- Pending changes. A recent number change or an open request on the account can block a port. Fix: let it settle, then try again.
- Account owner not available. The person on the account cannot sign in. Fix: recover the account through Google before anything else.
- Number not eligible to port in. A landline or VoIP number was submitted to Google Voice. Fix: use a different approach, covered below.
When a request is rejected, ask your provider for the exact rejection reason. It is usually a one-line explanation, and fixing that single field often clears the port on the second attempt. Our guide on what to do when your service provider won’t port your number walks through the next steps, and our eligibility article explains which numbers can move.
Landline or VoIP number you want in Google Voice
If your number is a landline or sits on a VoIP service, Google Voice will probably not take it directly. You have a few routes:
- Move it to a mobile carrier first, then port it into Google Voice. This adds a step and some cost.
- Keep the number where it is and forward it to a Google Voice number. Calls arrive, but you do not fully control the number.
- Port it to a business phone service that accepts landline and VoIP numbers. This is often the cleaner answer for a business, because those services are built to take these numbers and add routing, texting, and voicemail on top.
For a business, the third route usually makes the most sense. You keep the number customers know, and you are not tied to a consumer app’s eligibility limits.
Perspective: why we move businesses off consumer numbers
We see the same story often. A business starts on a free number because it is quick. The number goes on the website, the truck, the business card. Two years later, the owner wants calls to ring the right person, texts to go to a shared inbox, and an after-hours greeting that sounds professional. The number is still in a consumer app, and the app does not do those things.
That is when the owner searches for how to port the number. Our advice is to treat the port as a planned project, not a rescue. Unlock the number, collect the exact account details, and keep the old account open until the new line is proven. A port done on a quiet Tuesday is a non-event. A port rushed on the day a campaign launches is where numbers get lost.
We built Talkroute for small and midsize businesses that want enterprise-style features without desk phones or complicated setup. It runs on the phones and computers your team already has. You get call routing, auto-attendant menus, business texting, voicemail with transcription, and video meetings in one app, and our team helps you through the porting steps. Your number stays yours, and your customers never need to learn a new one.

What to set up once the number lands
A ported number is only worth it if the line works better afterward. A short checklist for the first day:
- Greeting and hours. Record a greeting and set business hours so after-hours callers hear the right message. Our auto attendant handles menus such as “press 1 for sales.”
- Call routing. Decide who answers first, and where calls go if nobody picks up. See our support section on call forwarding and routing.
- Texting. If customers text your number, confirm texting works from the business app. Business text messaging lets several teammates see the same conversations.
- Voicemail. Turn on transcription and email notifications so voicemails reach you quickly. Our voicemail help section covers setup.
- Extra numbers. Adding a toll-free or second local line costs $5 per month per number on our plans. See toll-free or local number if you are deciding which to use.
For US local numbers used for texting, carrier registration may apply. Our pricing page lists the one-time local number registration fee and the monthly campaign fee, so you will see them before you commit.
Move your Google Voice number to Talkroute
If your Google Voice number is the one on your website and your invoices, we can move it for you without changing what customers dial. You keep the number, add team features, and run it from desktop, web, and mobile apps. Setup takes minutes once the port is complete, and there is no hardware to buy.
See Talkroute plans and pricing to pick the plan that fits your team, or read about our phone number porting process first. Our support team also keeps a porting help section with step-by-step articles.
FAQ
Can I port my Google Voice number to another carrier?
Yes. Unlock the number in your Google Voice settings, then give your new provider your Google Voice number as the account number and your voicemail PIN as the PIN. The new provider submits the request. Keep your Google Voice account active until the port is complete.
How long does it take to port a number?
The FCC says simple ports between wireless providers are required to be processed in one business day. Ports involving Google Voice or landlines can take longer, often a few days. Your new provider can give you an estimate once the request is submitted.
Can I port a landline or VoIP number into Google Voice?
Google Voice generally accepts mobile numbers only for porting in. For a landline or VoIP number, you can move it to a mobile carrier first, forward it, or port it to a business phone service that accepts those number types.
Will I lose my number if the port fails?
Usually not. A rejected port leaves the number where it was, and you can fix the detail and resubmit. The risk comes from canceling or deleting the old account before the port finishes, so keep it open until the new service is confirmed.
Do I need to cancel Google Voice after porting?
Once the number is live on the new service and you have tested calls and texts, you can close the Google Voice account. Save voicemail and text history you need before you do.
