Buying or selling on Facebook Marketplace? The payment method is the whole scam
Peer-to-peer marketplaces like Facebook Marketplace, Craigslist, and OfferUp give you no built-in refund or protection — so the payment rail you choose is the protection. Here is how the scams work on both sides, and the rules that hold.
Buying and selling between strangers on Facebook Marketplace, Craigslist, or OfferUp is mostly fine — millions of trades go through every week. But when one goes wrong, the loss is almost always about how the money moved, not what was being sold. As the FTC puts it, “Craigslist, Facebook Marketplace, and other sites attract a lot of buyers — and scammers.”
The thing to understand first: unlike buying from a store, a peer-to-peer marketplace gives you no built-in refund, escrow, or guarantee. The platform introduces you to the other person and then steps back. So the payment method you choose is not a detail — it is the protection.
If you’re buying
A scam listing wants your money to leave by a door that does not open again. Two free habits and one payment rule cover most of it:
- Check who you’re dealing with. The FTC suggests searching the seller and item online with the word “complaint” or “review”, and reading widely — “don’t rely on star ratings alone because some reviews and ratings are fake or misleading.”
- Pay with a credit card, or pay on pickup. A credit card gives you legal protection: if you are charged twice, billed for something you never got, or sent the wrong or defective item, you can dispute the charge.
- Never pay a stranger by gift card, crypto, cash-reload card, or wire. The FTC is blunt that paying this way “is like sending cash — once it’s gone, you generally can’t get it back.” A seller who only accepts those is telling you something.
If you’re selling
The scams flip when you are the one being paid. The con is to make you part with the item before any real money reaches you:
- The fake “payment sent” notification. A “buyer” sends a screenshot or email that looks like a transfer, the FTC warns, “hoping you’ll send the item before you realize it’s a scam.” A notification is not money. Open your own bank or payment app and confirm the funds have actually settled.
- The overpayment trick. They “accidentally pay you twice and ask you to refund one of the payments”, or send a check for more than the price and tell you to “deposit the check and send the difference back.” The first payment is fake or will reverse; the refund you send is real. This is the same machinery as the fake-check overpayment scam — never send money back on an overpayment.
- The “verify you’re real” code. A “buyer” texts you a verification code and asks you to read it back to prove you are not a bot. That code is being used to hijack an account in your name — it is the verification-code (OTP) theft scam wearing a marketplace costume. Never share a code anyone sends you.
The rule that holds on both sides
Payment apps and bank transfers move money like cash: fast and, in practice, one-way. When the CFPB sued three large banks over fraud on the Zelle network in December 2024, it alleged that consumers “couldn’t protect themselves or reverse unauthorized transfers once they were sent.” Whatever became of that particular case, the underlying fact has not changed: once you send a payment-app transfer or a bank wire to a stranger, getting it back is rarely possible. That is exactly why a stranger on a marketplace prefers those rails, and exactly why you should not use them with someone you have not met.
So keep The Pause on Money on every deal: as a buyer, pay by a method you can reverse or by cash on pickup; as a seller, do not release the item until the money has truly landed in your account. Pressure to rush, to ship a local item, or to switch payment methods is the red flag itself.

- The other person pushes you onto one specific payment rail — Zelle, Cash App, wire, or gift cards — and resists anything reversible like a credit card or paying on pickup.
- A "buyer" sends a screenshot or email that looks like a payment confirmation, but nothing has actually landed in your own account.
- They "accidentally" overpay — or send a check for more than the price — and urgently ask you to refund the difference.
- The deal is rushed, the person can never meet in person, and shipping is required even for a local listing.
- A "buyer" asks you to read back a verification code they texted you "to prove you are real" — a separate account-takeover trick.
- On a peer-to-peer marketplace there is no built-in buyer or seller protection — the payment method you choose is your protection.
- As a buyer: pay with a credit card, or pay in person on pickup. Never send gift cards, crypto, a wire, or a payment-app transfer to a stranger — the FTC warns those are like cash, and "once it's gone, you generally can't get it back".
- As a seller: confirm the money has actually settled in your own bank or app account before you hand over or ship anything. A "payment sent" screenshot or email is not proof.
- Never refund an "overpayment". A real buyer does not overpay and ask for change; that is the overpayment scam, and the original payment is usually fake or will be reversed.
- Meet in a safe, public place for local deals, and treat any pressure to rush or to switch payment methods as the red flag itself.
The pattern I keep seeing is that people lose money not because they misjudged who they were dealing with, but because they trusted the wrong thing — a screenshot, a 'payment sent' email, a promise to 'sort out' an overpayment. On these platforms the other person can be a complete stranger and it is fine. What has to be real is the money landing in your account. Verify that one thing and most of these scams fall apart.

Frequently asked
A buyer sent me a screenshot showing they paid — is it safe to ship now?
No. A screenshot or "payment received" email is trivial to fake. Treat a sale as paid only when the money has actually settled in your own bank or payment-app account — open your own app and check the balance yourself. Scammers send fake notifications hoping you ship before you realize nothing arrived.
Why is paying by Zelle or Cash App riskier than a credit card?
Payment apps move money like cash — instantly and, in practice, irreversibly. The CFPB has said consumers often could not reverse unauthorized transfers once they were sent, which can make it nearly impossible to get the money back. A credit card, by contrast, lets you dispute a charge if the item never comes or is not as described. For strangers, that protection is the whole point.
The buyer overpaid by mistake and just wants the difference back. What's the harm?
That is the overpayment scam. The "buyer" pays too much — often with a fake check or a transfer that will later be reversed — then asks you to refund the difference by a method you cannot claw back. When the original payment bounces, you are out the refund and sometimes the item too. Never refund an overpayment; cancel the deal.
Is buying and selling on Facebook Marketplace or Craigslist just unsafe?
No — millions of safe trades happen. The risk is concentrated in two things: the payment method and meeting strangers. Pay (or get paid) by a method you can verify or reverse, meet in safe public places for local pickups, and walk away from anyone who rushes you or insists on an irreversible payment.
