What to know first

In this scam, someone offers to trade goods, such as phones or electronics, then swaps the agreed item for a fake, broken, or lower-value one during the exchange, leaving you with something worthless.

Marketplace scams target both buyers and sellers on platforms like Facebook Marketplace and classified listings. Fraudsters fake payments, send bogus "buyer protection" emails, push deals off-platform, or use overpayment tricks to make you ship goods or send money for nothing.

The core pattern to watch for is clear: A trade where the other party rushes the swap or distracts you during the handover. Inspect and test the item fully before handing yours over, in a safe public place.

Tell-tale red flags

  • Pressure to swap quickly without inspection
  • A 'sealed box' you are discouraged from opening
  • Distraction during the exchange
  • Refusal to power on or test the item
  • A meeting set somewhere isolated

Staying safe

  • Fully inspect and test the item before handing yours over
  • Open any boxes and verify the contents and serial numbers
  • Meet in a busy, well-lit public place and bring a friend
  • Check that electronics are not locked or blacklisted

How it usually reads

Example pattern, not a real report
Example pattern: 'Let's swap my phone for yours, mine's boxed and sealed.' At handover they hand you a sealed box that actually contains a fake or a brick.

This is a fictional, anonymised example used to illustrate the pattern. It is not a verified real message, and any names are used only to show how the scam typically reads.

What to notice: A trade where the other party rushes the swap or distracts you during the handover.

Steps if you already acted

  • If you were swapped a fake, report it to the police and platform
  • Keep the item received, messages, and any photos as evidence
  • Check device identifiers and report a blacklisted phone
  • Warn others by reporting the account

Common mistakes

  • Do not swap without inspecting and testing first
  • Do not accept a 'sealed' item you cannot open
  • Do not meet in isolated places

Blocked Phone Sale Scam

A blocked phone sale scam involves a second-hand handset that looks fine but is stolen, blocklisted by its IMEI, or still tied to the previous owner's account. After you pay, the phone may lose network service, refuse to activate, or stay locked behind someone else's login. Checking the IMEI status and confirming any account lock is removed before handing over money is the key protection.

Your questions answered

How do I trade items safely?
Inspect and test both items fully before exchanging, verify serial numbers, meet in a busy public place, and never let pressure or distraction rush you.
They insist the box stays sealed. Is that normal?
Insisting you not open a box before swapping is a warning sign. Verify the actual contents before handing over your item.
I was given a fake. What now?
Report it to the police and the platform, keep all evidence, and check device identifiers so a blacklisted phone can be flagged.
How can I check a phone is genuine?
Power it on, test it, confirm it is not locked to an account, and verify its identifier is not reported lost or stolen.
