You list a couch, and within minutes an eager buyer offers full price, no haggling, and wants to pay by Zelle right now. Then comes an email saying the payment is “pending” until you do one small thing. That small thing is the scam.
Selling on Facebook Marketplace and similar platforms is a great way to clear out clutter and make a little cash. It is also a hunting ground for a handful of well-worn scams aimed squarely at sellers. The good news is that they follow predictable scripts. Learn the three big ones and the red flags around them, and you can sell to real buyers while spotting the fakes before they cost you anything. Here is how.
The Short Version
Most Marketplace seller scams come down to fake money. A buyer “overpays” with a doctored screenshot and asks for a refund, sends a fake payment-confirmation email to rush you into shipping, or asks you to read back a verification code that hijacks your phone number. The defense is simple: only trust money you can see inside your own banking or payment app, and never share a code anyone texts you.
The Overpayment Refund Scam
This one preys on your sense of fairness. The buyer sends more than the asking price, then contacts you flustered, saying they overpaid by accident and asking you to refund the difference. They may show a screenshot proving the larger payment.
The trick is that the original payment is fake or will later be reversed, while the refund you send is real money leaving your account. You end up out the difference and often the item too. No legitimate buyer overpays and then asks you to send cash back. If a payment comes in wrong, the fix is for the payer to dispute it with their own bank, not for you to wire the balance to a stranger.
The Fake Payment Confirmation
Here the buyer claims to have paid through Zelle, Venmo, or Cash App, but the money never shows in your app. Instead you get an official-looking email saying the payment is on hold, or that you need to “upgrade to a business account” and the buyer must send extra money you then refund. As security researchers tracking these payment scams note, those emails are forgeries and the links inside are phishing pages built to steal your login.
The rule that defeats this completely: never trust an email or a screenshot as proof of payment. Open your actual banking or payment app yourself and confirm the money is really there and settled. If it is not sitting in your account, you have not been paid, no matter how convincing the email looks.
The Google Voice Code Trap
This scam does not even want your item. A “buyer” says they want to make sure you are a real person, not a bot, and offers to send a verification code to your phone for you to read back. The code is actually a Google Voice or account verification code tied to your own number.
When you read it back, you hand the scammer the ability to create a Google Voice line in your name or take over an account, which they use for further fraud and identity theft, a pattern consumer guides keep flagging for Marketplace sellers. The defense is absolute: never read a verification code to anyone. A real buyer has no reason to verify you with a code, and any code texted to you is for you alone.
Other Red Flags to Watch
Beyond the big three, a cluster of smaller signals tends to surround a scam buyer. Any one is a reason to slow down.
- A brand-new or bare profile. Few friends, little history, or an account created days ago are common warning signs.
- Rushing and overpaying. Full price with no negotiation, plus urgency to pay immediately, is not how most real buyers behave.
- Pushing to move off-platform. A quick pivot to text, email, or a different app removes the platform’s paper trail.
- Insisting on shipping a local item. A “buyer” who cannot meet but will send a courier or prepaid label is often running a script.
- Zelle for a cash listing. Pressure to accept Zelle on an item you advertised as cash-only can be a stolen-card or reversal setup.
How to Sell Safely
You do not need to be paranoid to be safe. A few consistent habits shut down almost every version of these scams:
- Prefer cash for local sales. For in-person pickups, cash is simple and final. Count it before handing over the item.
- Verify money in your own app. Only treat a payment as real when you see it settled in your banking or payment app, opened by you, not through a link someone sent.
- Never share codes. No verification code you receive should ever be read back to a buyer, full stop.
- Keep it on the platform. Chat, pay, and arrange through the marketplace where possible, so there is a record if something goes wrong.
- Meet in a safe spot. Use a public place or a police-station “safe exchange” zone for pickups, ideally in daylight.
At a Glance
- The overpayment scam sends fake money, then asks you to refund the “extra,” leaving you out real cash.
- Fake payment-confirmation emails and screenshots are forgeries, so only trust money settled in your own app.
- The Google Voice code scam hijacks your phone number, so never read a verification code back to anyone.
- Watch for new profiles, overpaying, off-platform pivots, forced shipping, and Zelle pressure on cash listings.
- Sell safely with cash for local pickups, in-app verification, no shared codes, and public meeting spots.
Frequently Asked Questions
How can I tell if a Marketplace buyer is a scammer?
Watch the behavior more than the offer. Scam buyers often have new or empty profiles, pay full price without haggling, push to move off the platform, insist on shipping a local item, or claim to have paid while nothing appears in your app. Any of these is a reason to pause and verify.
Is it safe to accept Zelle or Venmo on Marketplace?
It can be, but only if you confirm the money has actually settled by opening your own banking or payment app. Never rely on an emailed confirmation or a screenshot, and be cautious if a buyer pressures you to accept an app payment on an item you listed as cash-only.
Why does a buyer want to send me a verification code?
They do not want to verify you, they want to hijack your phone number or an account. The code they send is tied to your number, often for Google Voice. If you read it back, they can use it for fraud and identity theft, so never share a code with anyone.
What should I do if I have been scammed on Marketplace?
Stop contact, report the buyer and listing to the platform, and contact your bank or payment app immediately if money left your account. Change passwords on any account you may have exposed, and report the scam to the FTC. Acting quickly gives you the best chance of limiting the damage.
What To Do Next
Selling online safely comes down to one mindset: money is not real until you can see it settled in an app you opened yourself, and nothing a buyer sends by email, screenshot, or text changes that. Keep local sales in cash, keep conversations on the platform, and treat any request for a code as an instant dealbreaker. Do that, and the scammers move on to easier targets while you close the sale with the buyers who are actually real. For more coverage, see ShoutPost’s Business and Finance & Money sections.
