Facebook Marketplace Scam: What To Do If a Buyer or Seller Tries To Trick You

Marketplace scams do not look like robberies at first. They look like ordinary local selling: a buyer asks if the item is still available, a seller says there is high demand, or someone wants to verify that you are real before they drive over. The damage starts when the conversation stops being about the item and becomes about codes, refunds, deposits, or links.

The FTC says online selling scams commonly use fake payment notices, fake check overpayments, and Google Voice verification-code tricks. Meta has also highlighted advance-payment scams and overpayment-refund scams on resale platforms such as Facebook Marketplace. That is the operating model. The scammer tries to move you from normal chat into a payment or identity step that benefits them and is hard to reverse.

Key idea: if the next step is outside normal buying and selling, stop treating it like a negotiation and start treating it like a scam check.

First 10 minutes

Pick the lane that matches the message you got.

• Keep the conversation in Marketplace or Messenger as long as possible.
• Save screenshots, listing URLs, profile links, and payment details before the other side disappears.
• Do not click links that claim to confirm payment or upgrade your account.
• If you already shared bank, card, or Facebook login information, contact the bank and secure the account before you do anything lower priority.

Why scam conversations drift off-platform

Scammers like text messages, email, and other apps because moving the conversation gives them more room to spoof payment notices, send phishing links, and erase the paper trail. Meta says to be cautious when someone wants to move early conversation off Facebook or Messenger. That is not a style preference. It is usually an attempt to move you away from the place where the platform can see the pattern and where you can still report the account cleanly.

If the other person insists that Marketplace is glitchy, that they do not trust Facebook, or that they need your phone number before they can send someone to pick the item up, slow down. The platform is not the problem. The control is the problem.

If a buyer wants your phone number or a verification code

The FTC's Google Voice scam alert describes a common pattern on Craigslist and Facebook Marketplace. The fake buyer claims they have seen fake listings before and want to confirm you are real. Then they send a Google Voice verification code and ask you to read it back. If you do, they can try to create a Google Voice number linked to your real phone number.

• Do not send the code back.
• Do not keep explaining why you will not send it. End the conversation.
• Report the profile and preserve the messages.
• If you already sent the code, use the FTC's Google Voice scam guidance and the Google reclaim steps it references, then watch for follow-on scam calls tied to your number.

A verification code is not proof that the buyer is careful. It is proof that the buyer wants you to hand over a security token that was sent to your phone for a different purpose.

If you got a payment email or screenshot but the money is not in your account

This is the most common seller-side turn. The buyer says they paid through Zelle, Venmo, Cash App, PayPal, or another service. Then you receive an email saying the money is pending, that you need to upgrade to a business account, or that you must send money first to unlock the payment. That email is usually fake.

The FTC warns that scammers send fake mobile-payment notifications and hope you ship the item before you realize there was no payment. The correct check is simple: open the real payment app or your bank account directly. Do not trust the email. Do not trust the screenshot. Do not trust what the buyer says the payment service requires.

• Check the payment inside the real app or on the real bank site you navigate to yourself.
• Do not ship, deliver, or mark the item sold until the money is actually there.
• Do not pay a fee to receive money.
• Do not let the buyer rush you because a driver is on the way.

If the fake notice arrived by email, compare it against the patterns in scam-email checks before you interact with links or attachments.

Common mistake: refunding or releasing a fake payment from your own real balance. That turns a fake incoming payment into a real outgoing loss.

If the buyer says they overpaid and wants a refund

Meta's payment-scam guidance and the FTC's selling-online alert describe the same underlying move. The scammer overpays, or claims to have overpaid using a fake receipt, and then asks you to send part of the money back. Once you send the refund, the original payment disappears, reverses, or was never real in the first place.

• Do not refund from your own funds.
• Stop the deal if the payment story no longer matches the listing price.
• If a real payment somehow did land, resolve it through the payment service's official support path, not through the buyer's instructions.
• Keep the screenshots and profile information because the overpayment story often shows clear evidence of intent.

This is one of the clearest cases where politeness costs money. You do not need to prove the person is a scammer before you refuse to send money back. The mismatch itself is enough reason to stop.

If you are the buyer and the seller wants money up front

Meta's May 2025 anti-scam article describes the advance-payment version directly: a seller on a reselling platform like Marketplace asks for money before shipment or delivery, then stops responding once paid. The closer the seller sounds to a normal local pickup, the easier it is to miss the shift.

• Be cautious with deposits for items you have not inspected.
• Be even more cautious when the price is unusually low and the seller says many other buyers are waiting.
• Do not use gift cards, cryptocurrency, or obscure payment routes to hold an item.
• If shipping is involved, verify the listing and seller carefully before paying anything.

If the seller will not let you inspect the item, keeps changing the location, or claims a relative will handle the exchange once you pay, the item may be bait. The real product is the deposit.

If the conversation moves to links, forms, or fake support

Some Marketplace scams are really phishing attacks wearing a buying-and-selling costume. The link says you need to confirm payment, view a shipping label, accept a business upgrade, or verify a refund. The real goal is to capture your Facebook login, email password, bank details, or card data.

• Do not sign in from links sent in chat, text, or email.
• Open Facebook or the payment app directly.
• If you already entered your Facebook password, change it immediately and review the account at what to do if your Facebook account is compromised.
• If you entered bank or card details, contact the financial institution before you continue reading scam advice.

Once credentials are in play, the incident is no longer just a bad listing. It is an account security problem too.

Report it before the evidence disappears

Platforms change menu labels, but the reporting principle is stable. Report the listing, the profile, and the message thread while the evidence is still live. Save screenshots first because scammers often delete listings, change names, or block you once they realize you stopped cooperating.

• Capture the listing URL, item title, price, and photos.
• Capture the profile name and profile link.
• Save payment emails, fake invoices, screenshots, and phone numbers.
• Report the scam to the platform and to the FTC at ReportFraud.ftc.gov.

If you met in person and the incident includes theft, threats, or a fraudulent check, add a local police report. Platform reports are useful, but they do not replace an incident record when money or safety is involved.

What to do if you already lost money

Recovery depends on how the money moved. Act fast and stay specific.

If the money exposure overlaps with a compromised bank account or a fake bank call, use bank-account incident response. Marketplace scams often blend into broader financial fraud once the scammer sees you are willing to move money quickly.

How to make the next transaction boring again

Safe Marketplace use is mostly about reducing improvisation.

• Keep the chat on Facebook or Messenger as long as possible.
• Do not share one-time codes with anyone who contacted you first.
• Check payments in the real app, never from screenshots or email alone.
• Prefer in-person exchange for local items when practical, and be clear about payment terms before meeting.
• If the other person keeps changing the process, end the deal.

Rule of thumb: honest buyers and sellers want the item. Scammers want the next step that has nothing to do with the item.

The hardest part about Marketplace scams is that the conversation often stays normal until the exact moment the scammer asks for something that does not belong in a routine sale. A code. A refund. A deposit. A link. That is why pattern recognition matters more than reading someone's tone.

The FTC and Meta descriptions line up on the same structural truth: the scammer needs you to step outside the normal transaction and into a side channel they control. Once you see that move, most of the scripts start to look interchangeable.

Clean recovery depends on whether you can separate the fake step from the real one. The real step is checking your own bank, your own payment app, your own Facebook security, and your own records. The fake step is anything the other person wants you to do before you verify those things yourself.

If a transaction stops feeling boring, that is usually the signal. Ordinary buying and selling is repetitive. Scams become memorable because someone is trying to pull you away from the ordinary controls that protect you.
