How to Avoid IMEI Scams on Facebook Marketplace & Craigslist

Facebook Marketplace, Craigslist and similar sites are where most used-phone scams happen. The IMEI is your best defense — if a seller fights it, walk away.

Red flags

• Price far below similar unlocked models.
• Seller refuses to share the IMEI before meeting.
• "Just sign in with my Apple ID" — classic activation-lock dodge.
• "It only needs a new SIM" — usually hides a blacklist flag.

The three checks that expose a bad deal

1. GSMA Blacklist Check — is it reported lost or stolen?
2. iCloud Activation Lock Check — can you actually activate it?
3. Full IMEI Check — device ID, blacklist and carrier in one report.

Meet safely

Always confirm the IMEI in person (dial *#06#) and run the lookup yourself before handing over cash. Never pay a deposit or ship a phone you have not verified.

Bottom line

A seller who hides the IMEI is hiding a problem. Check the blacklist, the lock and the full report before you pay.
