The Google Voice verification code scam is deceptively simple and devastatingly common. It is the number one scam reported to the Identity Theft Resource Center, accounting for 60% of all scam reports. The FTC has issued specific warnings about this scam, which targets millions of people who post listings on online marketplaces, classified sites, and social media. Despite its simplicity, most victims do not realize they have been scammed until their phone number is being used in criminal activity.

How the Google Voice Verification Code Scam Works

The scam follows a predictable pattern that exploits trust and the appearance of a reasonable request.

Step 1: The Scammer Finds a Target

The scammer browses online platforms — Craigslist, Facebook Marketplace, Nextdoor, OfferUp, or even lost pet listings — looking for posts that include a phone number. Sellers, landlords, and people posting about lost pets are prime targets because they expect and welcome contact from strangers.

Step 2: The Contact

The scammer reaches out about your listing, expressing interest. They may ask questions about the item, the rental, or the lost pet to establish a normal-seeming conversation. At some point, they say something like: "Before we meet up, I just want to make sure you're a real person and not a scammer. Can I send you a verification code to confirm?"

This request sounds reasonable. After all, there are plenty of scammers on these platforms, and wanting to verify someone sounds like a smart safety precaution.

Step 3: The Verification Code

The scammer goes to voice.google.com and begins the process of setting up a Google Voice number using your phone number as the linked number. Google sends a 6-digit verification code to your phone via text message. The scammer then asks you to read back or share that code.

Step 4: The Takeover

Once you share the code, the scammer completes the Google Voice setup. They now have a working phone number that is linked to your real number as a forwarding line. Your phone number is associated with their Google Voice account, and they can make calls and send texts that appear to come from a legitimate, traceable number — yours.

Step 5: The Criminal Use

The scammer uses the Google Voice number to:

• Run other scams — posting fake listings, sending phishing messages, or making fraud calls using a number that traces back to you, not them
• Commit identity theft — using your phone number as a verification tool to create accounts on other platforms
• Operate romance scams — maintaining a seemingly legitimate phone presence for romance fraud or pig butchering schemes
• Bypass two-factor authentication — using the number to intercept verification codes intended for accounts linked to your phone number
• Conduct business fraud — setting up fake business listings with a phone number that appears to belong to a real person

Why This Scam Is So Effective

The Google Voice scam succeeds because it preys on three psychological factors:

Reasonableness. In a world full of online scams, wanting to "verify" someone sounds like a smart precaution. Victims often share the code because they believe they are proving their own legitimacy.

Speed. The entire interaction takes less than two minutes. There is no time for the victim to research what is happening or realize the code is for Google Voice setup, not identity verification.

Minimal immediate impact. Unlike scams that take money directly, the victim does not experience an obvious loss at the moment of the scam. They may not realize their number has been compromised for weeks or months — until they discover their number linked to fraudulent activity.

Where This Scam Happens

The Google Voice scam has been documented across virtually every platform where people post listings with phone numbers:

• Craigslist — the original hunting ground for this scam
• Facebook Marketplace — increasingly targeted as the platform grew, alongside other Facebook Marketplace scams
• Nextdoor — exploiting neighborhood trust
• OfferUp and Letgo — local selling apps
• Lost pet listings — scammers target emotionally vulnerable pet owners
• Apartment and rental listings — landlords posting on multiple platforms
• Dating apps — scammers request "verification" as a safety pretense

How to Recover Your Google Voice Number

If you have already shared a verification code and your number has been claimed by a scammer, you can take these steps to recover it:

Method 1: Reclaim through Google Voice directly

1. Go to voice.google.com
2. Sign in with your Google account
3. Go to Settings (gear icon)
4. Look for the option to claim or verify your phone number
5. Google will send a new verification code to your phone — this time, keep it to yourself
6. Enter the code to reclaim your number and remove the scammer's access

Method 2: Use an alternative number

If the direct method does not work:

1. Get a temporary phone number from a friend, family member, or a prepaid SIM
2. Create a new Google Voice account using that temporary number
3. Once you have an active Google Voice account, transfer your original number to it
4. This removes the number from the scammer's account

Method 3: Contact Google Support

If neither method works, submit a support request through Google's Voice help center. Provide details about the scam and any evidence you have.

How to Protect Yourself

Never share verification codes. This is the single most important rule. No legitimate person or service needs a code that was sent to your phone. The code is for your accounts, not for anyone else's verification purposes.

Do not include your phone number in public listings. Use the platform's built-in messaging system instead. If you must share a phone number, use a Google Voice number you control rather than your real mobile number.

Know what verification codes look like. When Google sends a verification code, the text message clearly states it is for Google Voice setup. If you read the full text of the message instead of just the number, the scam becomes obvious.

Educate others. This scam disproportionately affects people who are less tech-savvy or unfamiliar with how verification codes work. Share this information with family members who sell items online.

Set up your own Google Voice number first. If you already have a Google Voice number linked to your phone, a scammer cannot link your number to their account. Creating your own Google Voice account proactively blocks this scam.

What to Do If You Have Been Scammed

1. Reclaim your number using the recovery methods above
2. Change passwords on any accounts that use your phone number for two-factor authentication
3. Report to the FTC at reportfraud.ftc.gov
4. Report to the platform where the scam originated (Craigslist, Facebook, etc.)
5. Monitor your accounts for any unauthorized activity, especially accounts using phone-based verification
6. Place a fraud alert on your credit reports through AnnualCreditReport.com if you shared any additional personal information
7. Report to the Identity Theft Resource Center at idtheftcenter.org for additional support

While losing your Google Voice number to a scammer may seem minor compared to other scams, the downstream consequences can be significant. Your number may be used to scam other people, and any criminal activity tied to that number traces back to you initially. Recovering the number quickly and filing reports creates a documented record that protects you.

The Google Voice scam teaches an essential lesson that applies far beyond this specific scheme: no one who contacts you online should ever need a code that was sent to your phone. That principle protects you from Google Voice scams, account hijacking on WhatsApp and Telegram, and a wide range of other verification code attacks. If someone asks for a code, the conversation is over.
