Facebook Marketplace Scam Warning Signs
Facebook Marketplace removes most of the friction of selling locally, which is great for legitimate users and equally great for scammers. There is no built-in escrow, almost all communication happens over chat, and verification of buyers and sellers is light. The result is that the same handful of scam patterns repeat in every city, every week.
If you are buying, the patterns to watch are off-platform payment, the verification-code trick, and "too good to be true" deals with shipping-only delivery. If you are selling, the patterns are fake check overpayment, buyer-canceled-shipping refund scams, and the same verification-code trick used to take over your phone number.
This guide lays out the patterns from both sides, plus what to do if you have already engaged.
Warning signs
- Price is dramatically below market for a popular item (electronics, branded handbags, designer shoes). The discount is the bait - the listing exists to extract a deposit or off-platform payment.
- Seller refuses to meet in person and insists on shipping. For local items this is the single strongest red flag.
- Payment is demanded via Zelle, Venmo Friends & Family, Cash App, gift cards, or wire transfer. None of these have buyer protection.
- A buyer or seller sends you a fake verification code and asks you to read it back "to prove you are real". This is account-takeover - they are using your phone number to sign up for a service and harvesting the one-time code.
- The other party pressures you to move the conversation off Messenger to text, WhatsApp, or Telegram. Marketplace's reporting tools only work inside Messenger.
- The shipping address provided is a freight forwarder or a vacant address. This is common in re-shipping scams used to launder stolen goods.
- A "buyer" overpays by check and asks you to refund the difference. The check bounces a week later and you owe the bank.
- Listings without a real-context photo (no thumbnail of the actual item with a hand or a household reference). Stock photos are easier to scam with.
What to do
- Meet in person at a safe public spot. Many police stations now offer designated exchange zones with cameras.
- Pay only in person, in cash or via a method that protects buyers. Avoid Friends & Family on any peer payment app.
- Never share a code that was sent to your phone or email, no matter how it is framed.
- Keep the conversation inside Messenger. Marketplace's report and ban tools work on in-platform messages.
- Use FakeOrLegit if any link is sent in chat - especially anything that looks like a tracking page or a payment confirmation.
- If you receive a check, do not refund anything until the check has cleared, which can take 5-10 business days. "Available funds" is not the same as cleared.
- If a buyer cancels and asks for a refund via a non-original method, refund only via the original method.
- Report the listing or user via Marketplace's report tool; persistent reports speed up bans of the underlying account.
