Marketplace buyer scam

Quick answer

A scammer poses as a buyer to trick a seller into shipping goods or refunding an 'overpayment' before any real payment clears.

  • Confirm money has actually arrived in your account through your bank, not a message.

What it is

A scammer poses as a buyer to trick a seller into shipping goods or refunding an 'overpayment' before any real payment clears.

How it works

The 'buyer' sends a fake payment confirmation or claims to have overpaid, then pressures you to ship or refund the difference.

Red flags to watch for

  • Payment confirmation by email or screenshot only
  • Overpayment with a request for a refund
  • Pressure to ship before funds clear
  • Use of a courier they arrange

Example

A buyer sends a payment screenshot and asks you to ship immediately. This is risky because the payment may be fake and the screenshot proves nothing.

What not to do

  • Do not ship before funds clear in your account
  • Do not refund overpayments

The safe next step

Confirm money has actually arrived in your account through your bank, not a message.

Often seen on: Facebook Marketplace, Classifieds, WhatsApp.

Commonly targets: Private sellers.

How to verify safely

  • Do not use links, phone numbers, QR codes, or email addresses from the suspicious message.
  • Open the official app or website yourself - type the address manually.
  • Call a contact you have saved, or the number printed on your bank card.
  • If you are threatened or in immediate danger, contact local emergency services or police.
