Facebook Marketplace has become a popular platform for buying and selling items locally. It offers a convenient way for people to list items for sale and connect with potential buyers in their area. However, the use of Facebook Marketplace has also given rise to some scams and risky situations.
One common scam involves sellers asking buyers to text them a Google Voice verification code in order to complete a purchase. This raises the question – why do people request Google Voice codes on Facebook Marketplace, and is it actually safe to provide the code to them?
What is a Google Voice verification code?
Google Voice is a free calling and texting app provided by Google. It provides the user with a virtual phone number that can be used to make calls, send texts, and access voicemail.
When setting up a new Google Voice number, the service will send a 6-digit verification code via text message to the user’s real cell phone number. This code is used to verify ownership of that number.
The same verification code process is used if a Google Voice user tries to add another phone number to their account. The system sends a code to the new number being added, which must then be entered into the Google Voice app in order to link that number.
Why do sellers request the code?
There are a few reasons why sellers on Facebook Marketplace might request the Google Voice verification code from potential buyers:
To try and take over the buyer’s number
One fraudulent reason is that the seller is trying to hijack the buyer’s phone number. Here’s how it works:
The seller has set up a Google Voice account using a temporary phone number. When the buyer sends their Google Voice verification code to the seller, the seller can then enter that code into their Google Voice app. This links the buyer’s cell phone number to the seller’s Google Voice account.
Once their number is linked, the seller can then redirect all calls and texts sent to the buyer’s number through their own Google Voice account. This gives them control over the buyer’s number.
To confirm the buyer’s identity
Some sellers claim that they request the Google Voice code in order to confirm the buyer’s identity and ensure they are a legitimate, trusted person. However, this is not a reliable verification method and buyers should not provide their code for this purpose.
To determine if the number is “valid”
Other sellers say they ask for the code to check if the buyer’s number is a valid, working phone number. While this may sound reasonable, there are better ways to confirm a working number, such as having the buyer call or text the seller’s number.
As part of a scam
Unfortunately, some sellers have malicious intent behind requesting the Google Voice code. Providing the code gives scammers access to the buyer’s number, which they can then use to facilitate fraud.
For example, after linking the number to a Google Voice account, the scammer may try to reset passwords on the buyer’s other online accounts, harvest personal information, or sell the number to other scammers.
Is it safe to provide the code?
In most cases, no, it is not safe for buyers to give out their Google Voice verification code to sellers on Facebook Marketplace.
Legitimate sellers should never require this code to complete a transaction. Sending the code gives the recipient temporary access to your number, which could allow them to compromise your online accounts or steal your identity.
| Is it safe to send the Google Voice code to… | Yes | No |
|---|---|---|
| A seller on Facebook Marketplace | X | |
| Someone you know well and trust | X | |
| A stranger who claims they need to “verify your number” | X |
As shown in the table above, the only person you should provide your Google Voice code to is a known, trusted contact who requests it for a legitimate reason. When in doubt, do not share the code.
Red flags a seller is trying to scam you
Here are some common red flags that indicate a seller’s request for your Google Voice verification code is likely a scam:
They avoid communicating on Facebook Marketplace’s platform
Scammers will often try to move the conversation off Facebook and communicate via text, email, or phone calls instead. This takes the transaction “off the record” and avoids any accountability.
They claim the code is to “verify your number”
As mentioned, this is not a valid reason for a seller to need your Google Voice code. A more likely explanation is they want to steal your number.
There are spelling/grammar errors in their messages
Scammers are often foreign fraudsters who may not have a strong grasp of English. Multiple spelling or grammar mistakes can be a red flag.
They send suspicious links
Beware if a seller sends you links to external sites asking for personal information or Download files. This is a technique scammers use to harvest data or install malware.
They have zero reviews on their profile
While new sellers have to start somewhere, those with no reviews should be approached cautiously, as you have no way to verify they are legitimate.
They request unusual payment methods
Scammers may ask for payment via money order, gift cards, Venmo, Zelle, PayPal Friends and Family, or other hard-to-trace options.
How to avoid scams requesting Google Voice codes
Here are some tips to stay safe and avoid scams when buying or selling on Facebook Marketplace:
Never provide your Google Voice verification code
No matter how convincing the story, there is no good reason for a seller to need this code from you. Don’t give in to requests for it.
Keep all communication on Facebook
Don’t continue the conversation over text or other platforms. Keeping it on Facebook provides a record and accountability.
Beware if the price seems too good to be true
Unusually low prices can be bait to lure in unsuspecting buyers. Scammers often “hook” victims with the promise of a great deal.
Ask to meet in person before paying
Don’t provide payment until you have met the seller and verified the item is as described. This gives you a chance to assess any red flags.
Do research on high-value items
For expensive or rare items, search online to make sure the item actually exists and the seller has title to it.
Avoid sellers unwilling to talk on the phone
Talking allows you to get a feel for the seller. Scammers will often make excuses to avoid direct conversation.
Use Facebook Marketplace’s payment system
This offers protection for buyers. Payments via Facebook also provide a record of the transaction.
Trust your instincts
If something seems suspicious or “off,” it probably is. Don’t ignore any gut feelings that a seller is not legitimate.
What to do if you shared your code
If you unfortunately already provided your Google Voice verification code to a suspicious seller, take these steps right away:
Change your Google Voice password
This prevents the scammer from accessing your Google Voice account now that they have the code.
Remove the linked phone number
Unlink your cell phone number from your Google Voice account. You can add it back once the code expires.
Contact your phone carrier
Let them know your number may be compromised. They can take steps to protect your number and account.
Enable two-factor authentication
Add two-factor authentication to your Google, Facebook, and any other key accounts for extra security.
Monitor accounts closely
Watch for any suspicious activity and review statements frequently for signs of fraud.
Change passwords
Update passwords on all important online accounts, making them long and complex.
Submit scam report
Report the scam to Facebook Marketplace and other relevant authorities to help warn others.
The bottom line
Requests for your Google Voice verification code should raise major red flags when interacting with sellers on Facebook Marketplace. This information allows access to your number and can lead to identity theft or financial fraud.
Protect yourself by keeping communication on Facebook, dealing locally in-person, saying no to verification code requests, and trusting your instincts. If you do share the code, take action quickly to minimize the risk and prevent any misuse of your accounts. Staying vigilant is key to avoiding scams.
