Google Voice gives you a free US phone number that works anywhere in the world — free calls and texts within the US, cheap international rates, voicemail transcription, and a clean separation between your real number and the number you hand out. It’s one of the most genuinely useful free tools Google offers.
Here’s the problem: to get a Google Voice number, Google requires you to verify with an existing US phone number. If you’re outside the US, or you don’t want to use your personal number, you’re stuck. You need a number to get a number.
A virtual US number from SMSCode breaks that loop. You use it once, for the Google Voice verification step, and then you have a permanent free US number that you own going forward.
TL;DR: Get a US virtual number from SMSCode (from $0.20), use it to verify your Google Voice number claim at voice.google.com, and then keep your Google Voice number indefinitely. You must use a US IP address during setup (VPN if you’re outside the US). Google Voice rejects VoIP numbers — SMSCode’s SIM-based US numbers have the best success rate for this.
The irony of needing a number to get a number
Google Voice’s verification requirement exists to prevent mass number farming and to ensure accounts are linked to real people with real US phone relationships. The policy makes sense from Google’s perspective. From a user’s perspective, it creates a genuine catch-22:
- You want Google Voice to have a disposable US number for signups and listings
- But to get Google Voice, you need a US number you’re willing to link to your Google account
- Your personal US number is the thing you were trying to avoid using
Virtual numbers solve this cleanly. The SMSCode number receives the verification SMS once, you claim your Google Voice number, and then the virtual number’s job is done. Your Google Voice number is the permanent one — the one you use going forward. The virtual number was just the key to unlock it.
Why people want Google Voice
A permanent US number that follows you globally. Once registered, Google Voice works over the internet from anywhere. International users, expats, digital nomads, and remote workers use it to maintain a US presence without US carrier costs.
Privacy buffer for online signups. Many websites, services, and classifieds require a phone number. Google Voice gives you a number to use for these without exposing your personal carrier number. Your real number stays private; your Google Voice number absorbs the exposure.
Business line without carrier costs. Freelancers, consultants, and small businesses use Google Voice as their business number. It routes calls to any device, has voicemail with transcription, and costs nothing for the number itself.
Free US calling from abroad. Google Voice provides free calls to US numbers from anywhere with internet — useful for anyone with US clients, family, or business contacts.
Number porting. If you later want to move your Google Voice number to a carrier plan, Google allows porting for a one-time fee. Some people use this to acquire a good US number through Voice and then port it to a carrier when they move to the US.
Separation for professional contexts. Therapists, real estate agents, lawyers, and other professionals who need to be reachable but want to control when and how clients contact their personal line use Google Voice as a professional forwarding layer — calls go through Voice’s app during work hours and can be silenced outside of them.
What you’ll need
- A Google account (Gmail)
- An SMSCode account (free to create)
- A balance of $0.20–$0.50 (US numbers cost more than other countries — this is expected for a one-time setup)
- A US IP address — use a VPN with a US server if you’re outside the US
- About ten minutes
Step-by-step: setting up Google Voice with a virtual number
1. Get your US IP address sorted first
If you’re in the US, skip this. If you’re outside the US, Google Voice will refuse access — it checks your IP location and shows an error if it detects a non-US connection. Use a VPN with a US server before proceeding. Any reputable VPN with US servers works.
2. Create your SMSCode account
Go to smscode.gg and register. Fund your account via crypto, bank transfer, or e-wallet. New accounts receive a 5% deposit bonus.
3. Find Google or Google Voice in the service list
Search for “Google Voice” or “Google” in the SMSCode dashboard. Select it and choose USA as the country.
This is the only option that works — Google Voice only accepts US numbers for verification. Numbers from other countries are rejected outright.
4. Get a US virtual number
Click “Get Number.” Your US number is reserved for 15–20 minutes. Keep the SMSCode dashboard open — you’ll be returning to it shortly for the code.
5. Go to voice.google.com
Navigate to voice.google.com and sign in with your Google account. Google Voice will walk you through choosing a number.
6. Search for and claim your Google Voice number
Google Voice lets you search available numbers by area code, city, or word pattern. Choose a number you like — this will be your permanent Google Voice number. Click “Select” to claim it.
7. Verify with the virtual number
Google Voice asks you to verify by sending a code to a US phone number. Enter the virtual US number from your SMSCode dashboard (include the +1 country code).
8. Retrieve and enter the code
Google Voice sends a 6-digit SMS code. Open your SMSCode dashboard — it typically arrives within 30 seconds. Enter the code in Google Voice and confirm.
9. Your Google Voice number is active
You now have a free US phone number. Make calls through the Google Voice app, web browser, or by forwarding to another number. The virtual number’s job is done.
Why Google Voice rejects many virtual numbers — and what to do about it
Google Voice is notably stricter than most services about the type of phone number it accepts for verification. It has detection systems that flag and reject VoIP numbers — numbers routed through internet telephony rather than real carrier infrastructure.
This is why success rates vary so much across virtual number services. Many providers offer VoIP-based numbers that Google Voice recognizes and rejects. SMSCode uses SIM-based numbers routed through actual carrier SIM hardware. Google Voice treats these identically to standard carrier-issued numbers. For more on this distinction, see our number quality and reliability guide.
If a US number gets rejected, cancel it on SMSCode (no charge if the code wasn’t delivered) and try again. Success rates for SIM-based US numbers on Google Voice are meaningfully higher than for VoIP numbers, but no service guarantees 100% acceptance.
Why some numbers work and others don’t. Google Voice’s VoIP detection operates at the number range level — certain blocks of US phone numbers are classified as VoIP by NANP (North American Numbering Plan) databases, and Google checks these. SIM-based numbers from physical carrier allocations are in different number ranges and don’t match the VoIP classification. The practical implication: if one number gets rejected, a different number from the same SIM pool may work since the specific number range matters.
What Google Voice can and can’t do as your “main” number
Google Voice is powerful but it has limitations worth understanding before you commit to it as your primary US number:
What works well:
- Free calls and texts to US/Canada numbers
- Voicemail with reasonably accurate transcription
- Call forwarding to any other number
- Works from any device with internet access
- Receiving verification codes from many services
Known limitations:
- Some services detect Google Voice as VoIP and reject it for their own verification (ironic, but real)
- 911 emergency calls require manual address setup and may not work reliably
- Not suitable for banking SMS verification in some cases
- Requires occasional use to avoid number reclamation (activity every few months)
- Google Voice to Google Voice calls count as free; calling a VoIP-only provider may have rates
For SMS verification needs beyond Google Voice’s use case, services like SMSCode give you temporary numbers for one-time verifications without the setup overhead.
Tips for long-term Google Voice management
Keep the number active. Google may reclaim inactive numbers. Make at least one call or send one text every few months to keep the number active.
Use it as your buffer number. Once you have Google Voice, you have a legitimate US number to give out for signups, listings, and services you don’t fully trust with your real number. This is the main ongoing value proposition — you get a permanent, disposable-ish US number for the cost of one SMSCode purchase.
Port it if you move to the US. Google charges a one-time fee to port a Voice number to a carrier. If you ever get a US SIM plan, you can bring your Google Voice number with you.
Set up call forwarding. Route Google Voice calls to your actual phone so you don’t miss calls. This works from anywhere globally.
Consider the Google One Voice plan. Google offers enhanced Google Voice features through Google One for paid subscribers, including more minutes and international calling features.
Use the Google Voice app, not the website for everyday use. The Google Voice mobile app (available on iOS and Android) integrates more smoothly for regular use — push notifications for incoming calls and texts work reliably in the app where web-based notifications can be inconsistent.
Troubleshooting Google Voice setup
“Google Voice is not available in your country” — You’re accessing from a non-US IP. Enable your VPN with a US server and try again.
“We couldn’t verify this number” — Google Voice rejected the virtual number, likely because it detected it as VoIP. Cancel on SMSCode and try a different US number.
“This number has already been used for Google Voice verification” — The number was previously used. Get a fresh US number from SMSCode.
“Google Voice wants to call instead of text” — Sometimes Google Voice offers voice call verification instead of SMS. Choose SMS if available. SMSCode numbers receive SMS, not inbound calls. If only call verification is offered for a particular number, cancel and try a different number.
“I can’t find an area code I want” — Some area codes have limited number availability. Try nearby area codes or search by city name instead.
FAQ
Is Google Voice actually free?
Yes — the base service is free. Google Voice provides a US phone number, free calls and texts to US and Canada numbers, and voicemail transcription at no ongoing cost. The only expense is the SMSCode virtual number for the one-time verification step, which costs $0.20–$0.50. International calls from Google Voice have per-minute rates, which are generally lower than standard carrier rates.
Can I use Google Voice outside the US after registration?
Yes. After registration, Google Voice works over the internet from anywhere in the world. You only need a US IP address for the initial signup — after that, use it from any country. The Google Voice app works globally as long as you have internet access.
Does Google Voice work for receiving SMS verification codes from other services?
Sometimes. Many services accept Google Voice numbers for their own SMS verification. Others have implemented VoIP detection that flags Google Voice numbers and rejects them. It works broadly but isn’t universal. For services that reject Google Voice, a temporary virtual number from SMSCode is the practical alternative — see our guide on cheap virtual numbers for context.
Can I keep my Google Voice number indefinitely?
Yes, as long as you use it occasionally. Google’s policy is to reclaim numbers that have been completely inactive for an extended period. Making a call or sending a text every few months is sufficient to keep it active. There’s no monthly fee for the basic service.
Can I use Google Voice to verify other Google services like YouTube or Gmail?
Google treats Google Voice numbers as VoIP numbers for its own verification systems — so you generally cannot use a Google Voice number to verify another Google account. This is one of the platform’s notable limitations. For verifying Google products, you need a carrier-issued number or a SIM-based virtual number from a service like SMSCode. For more on this, see our API guide and the virtual number guide.
How many Google Voice numbers can I have?
Each Google account can have one Google Voice number. If you need multiple US phone numbers, you’d need multiple Google accounts, each with its own Google Voice number. Alternatively, Google Voice for Google Workspace accounts can have multiple numbers under certain business plans.
