How to Tell if an iPhone Is Stolen or High-Risk
Buying a stolen phone does not just cost you money — it can lock after a few days, get blocked from networks, or drag you into a problem you did not cause. The good news: most cases have clear signs if you know what to look for.
01

A price that is too good

The first and most obvious signal. If the price is far below market for the same model and condition, ask yourself why.

  • Compare several listings for the same model and storage
  • A seller in a big rush deserves extra attention
  • Never let the price rush you past the inspection

02

Refusing to turn off Find My

A real owner can turn off Find My and sign out of iCloud in a minute. Refusing or making excuses is the strongest red flag.

  • "I forgot the password" or "it is my brother's account" = do not buy
  • A passcode the seller does not know = do not buy
  • Activation Lock screen after erase = the phone is locked

03

Receipt, box and matching numbers

A receipt is not always required, but it helps. What matters most is that the numbers match.

  • Match serial and IMEI in Settings with the box
  • Ask where and when it was bought and compare with the serial check
  • A box with different numbers = red flag

04

Reports and blocking

Some stolen or unpaid phones get their IMEI blocked by carriers, so the phone works but has no signal.

  • Put your own SIM in and confirm you get a signal
  • A "Lost Mode" message on screen = a lost device
  • Run a serial check to see activation status first

What to do if in doubt

Simple rule: if there is doubt, walk away. There are plenty of other phones.

  • Never pay a deposit before inspecting
  • Meet in a public place
  • Have the phone erased and set up in front of you
  • Buy from a seller who inspects and documents devices

Check the device before you pay

Start with a SerialKSA serial check, then finish the hands-on inspection in front of the seller.
