Complete Phone Verification Guide: IMEI Check & Stolen Phone Lookup
Why Phone Verification Matters
Over 2 million smartphones are stolen in the United States every year, with many ending up for sale on secondhand marketplaces. Buying a stolen phone isn't just financially risky—it's potentially illegal and can lead to your device being remotely locked or seized by authorities.
Whether you're buying from eBay, Facebook Marketplace, OfferUp, or Craigslist, verifying a phone's IMEI number is your most powerful protection against fraud. This comprehensive guide teaches you everything you need to know about phone verification.
What Is an IMEI Number?
IMEI (International Mobile Equipment Identity) is a unique 15-digit code assigned to every mobile phone. Think of it as your phone's fingerprint—no two devices share the same IMEI.
Format: 123456789012345

Red Flags When Buying Used Phones
Seller Refuses to Provide IMEI
Legitimate sellers have no reason to hide IMEI numbers. Refusal indicates the phone is likely stolen or blacklisted.
Price Significantly Below Market Value
A brand new iPhone for 50% off retail is almost certainly stolen. Check current market prices before buying.
Find My iPhone Still Enabled
If Find My iPhone or Android Device Protection is active, the previous owner can remotely lock or erase the phone at any time.
No Original Packaging or Receipt
Stolen phones rarely come with boxes or proof of purchase. Ask for documentation before buying.
Seller Has Multiple Identical Phones
Multiple iPhones or Samsung phones for sale simultaneously suggests organized theft operations.
Cash Only, Quick Sale Pressure
Scammers demand cash and create urgency to prevent verification. Take your time and verify before paying.
Step-by-Step: Buying a Safe Used Phone
Request IMEI Number Before Meeting
Ask the seller to provide the IMEI via message. Run it through SafeOrStolen's verification tool before scheduling a meetup.
Meet in Public, Bring SafeOrStolen App
Meet at a police station, bank, or busy public place. Use the SafeOrStolen mobile app to scan the IMEI barcode during the transaction.
Verify Find My iPhone Is Disabled
iPhone: Settings → [Your Name] → Find My → Find My iPhone should be OFF
Android: Settings → Security → Find My Device should be OFF
Factory Reset and Test
Have the seller factory reset the phone in front of you. Test that you can activate it with your SIM card before paying.
Get a Written Receipt
Create a bill of sale with IMEI, date, seller's name, and price. This provides legal protection if issues arise later.
What Happens If You Buy a Stolen Phone?
If you unknowingly purchase a stolen phone, you face multiple serious consequences:
