Google Voice Verification Scam: How Scammers Hijack Your Phone Number in 2026
The Google Voice verification scam is one of the most underestimated threats on online marketplaces in 2026. The FTC identified it as a top-reported fraud type, with victims unknowingly handing over control of a phone number that scammers then use for months or years of additional fraud. What seems like an innocent request to "verify you're real" is actually the first step in a sophisticated identity theft chain.
How This Scam Works
Scammer contacts you about your listing and claims they need to verify you're a real person because they've 'been burned before.'
They ask for your phone number, which seems reasonable for a local transaction.
Google sends a verification code to your phone — this is the scammer attempting to register a Google Voice number using your phone.
The scammer asks you to read back or text them the code as 'proof that you're real.'
Once they have the code, they link a Google Voice number to your phone. This number is now used for other scams, and all activity traces back to you.
Google Voice verification scams are among the most commonly reported fraud types to the FTC, with an estimated 60,000+ incidents reported in 2024 alone.
What People Are Saying

How proof.show Replaces Phone Number Verification Entirely
A buyer on Facebook Marketplace asks for your phone number to 'verify you're a real seller.' This is the setup for the Google Voice scam — they'll use your number to register a fraudulent Google Voice account. But you still want to prove you're legitimate. What's the alternative?
Instead of sharing your phone number, tell the buyer: "I verify through proof.show — no phone numbers needed."
You take a live proof photo at proof.show/capture showing the item you're selling. The camera blocks gallery uploads, so it proves the item is real and in your possession right now.
You share the 8-character Proof Code in the chat. The buyer enters it at proof.show/v and sees the verified photo with the timestamp — confirming you're a real seller with a real item.
Ask the buyer to do the same. If they're legitimate, they'll verify in 10 seconds. If they're a scammer, they'll disappear.
No phone numbers exchanged. No verification codes to steal. Both parties prove they're real through cryptographic photo verification instead of sharing exploitable personal information. The entire Google Voice scam becomes impossible.
Prevention Tips
Follow these steps to stay safe from this scam.
Never share verification codes sent to your phone with anyone — not a buyer, not a seller, not anyone claiming to be from Google or any platform.
Verify the buyer's identity through proof.show instead of sharing your phone number. A live, timestamped photo with SHA-256 verification proves they are a real person without exposing your personal information.
If someone insists on 'verifying' you through a code, end the conversation immediately. Legitimate buyers don't need verification codes to purchase an item.
If your Google Voice number has been compromised, visit voice.google.com to reclaim it by re-verifying your phone number.
Use proof.show's Proof Code as an alternative verification method — both parties can verify identity without exchanging phone numbers or personal data.
Frequently Asked Questions
A scammer asks for your phone number to 'verify you're real,' then triggers a Google Voice verification code to be sent to your phone. When you share the code, they hijack your phone number to create a Google Voice account linked to your identity, which they use for further fraud.

Yes. Visit voice.google.com and follow the steps to reclaim your number. You'll need to re-verify using the same phone number the scammer used. However, any scams committed using the hijacked number during that time may still be associated with your identity.
Use proof.show as a neutral, third-party identity verification tool. Ask the buyer to take a live photo through proof.show/capture — the SHA-256 hash and atomic timestamp prove they're a real person. You can verify their Proof Code at proof.show/v without exchanging any personal information.
