How to Check If a Used Phone Is Stolen
A great deal on a used phone turns into an expensive brick if the device is stolen or locked. A few minutes of checks before you pay saves the heartache.
The used-phone market is full of genuine bargains and a smaller number of traps. A stolen or carrier-locked device can be blocklisted from networks or tied to an account you can never access, leaving you with hardware you cannot use. The reassuring news is that a handful of straightforward checks will catch nearly every bad deal before any money changes hands.
Start with the IMEI
Ask the seller for the device's IMEI before you meet, and run it through a reputable IMEI status service. This will tell you whether the phone has been reported lost or stolen and whether it is blocklisted. A seller who refuses to share the IMEI is giving you all the answer you need.
Confirm the IMEI matches the phone
When you meet, dial star-hash-zero-six-hash on the actual device and confirm the displayed IMEI matches the one you checked and the one on the SIM tray or box. Mismatches suggest tampering or that you were sent details for a different, clean phone to pass the online check.
Check for activation locks
Modern phones tie themselves to the previous owner's account through an activation or reactivation lock. Before paying, have the seller fully sign out of their account and factory reset the device in front of you, then confirm it sets up fresh without asking for the previous owner's credentials. A phone still bound to someone else's account is unusable to you.
Inspect and test
- Confirm the IMEI is clean before meeting and matches the physical phone on arrival.
- Watch the seller sign out and factory reset, then set it up to confirm no activation lock.
- Insert a SIM and verify it connects to a network and can place a call.
- Test the screen, cameras, buttons, charging port, and battery health.
- Pay only after every check passes, and keep a record of the IMEI and the transaction.
Watch for pressure and red flags
Stolen-goods sellers rely on urgency and distraction. Be wary of prices far below market, refusal to meet in a safe public place, reluctance to share the IMEI, a phone that cannot be reset, or a story that keeps changing. Any single red flag is reason to slow down; several together mean walk away.
After you buy
Once the phone is yours, record its IMEI for your own records, set up your accounts and the find-my-device feature, and add a screen lock. If you ever discover after the fact that a phone was stolen, report it; knowingly keeping stolen property is itself an offense, and reporting protects you.
