IMEI Check for Facebook Marketplace Phones: Avoid Scams

6 min readUpdated 6/1/2025

Why You Must Check IMEI Before Buying a Phone on Facebook Marketplace

Facebook Marketplace is the world's largest peer-to-peer phone marketplace — and unfortunately one of the most common sources of blacklisted, stolen, and financed phones sold to unsuspecting buyers. Running an IMEI check before any Facebook Marketplace phone purchase takes 30 seconds and can save you hundreds of dollars.

The 5 Most Common Facebook Marketplace Phone Scams

  • Insurance fraud phones: Seller files an insurance claim on the phone, collects the replacement, then sells the original. Within 30 days, the original is blacklisted — after you've already paid.
  • Financed phones: Phone is still under a carrier payment plan. Once the seller stops paying, the carrier blacklists the IMEI. You own a brick.
  • Stolen phones: IMEI is reported stolen by the real owner days or weeks after the sale. Cannot be used on any US carrier.
  • iCloud-locked iPhones: Listed as "activation issue" or "needs Apple ID". The previous owner's Apple ID is permanently tied to the device — it cannot be activated.
  • Model fraud: A cheaper model sold as a premium one. Example: iPhone 13 listed as iPhone 14 Pro. IMEI lookup reveals the actual model.

What to Check Before Meeting a Facebook Marketplace Seller

  1. Ask for the IMEI in chat before meeting. Any legitimate seller will share it. Refusal = red flag.
  2. Run a free IMEI check at imeicheckpro.com to verify model and brand match the listing.
  3. Run a premium IMEI check to verify: blacklist status, iCloud lock, carrier lock, and financed/payment status.
  4. Check the listing date vs account age. Brand new accounts selling premium phones is a scam signal.
  5. Never pay in advance. Facebook Marketplace cash-on-delivery is the only safe payment method for phones.

The Insurance Fraud Timeline — Why Clean Today Can Mean Blacklisted Tomorrow

This is the most dangerous Facebook Marketplace scam because the IMEI checks clean at the time of purchase. Here's how it works:

  1. Seller has iPhone 15. Reports it stolen to their carrier insurance (e.g., Asurion).
  2. Carrier/insurer sends a replacement phone. Seller now has two iPhones.
  3. Seller lists the "stolen" original iPhone on Facebook Marketplace — it checks clean because the claim hasn't processed yet.
  4. You buy it. Within 2–8 weeks, the insurance claim finalises and the carrier blacklists the IMEI.
  5. Your phone stops working on all US carriers.

Protection: Buy from sellers with Facebook account history, meet in public, pay only after running IMEI check and powering on the device with your own SIM. For iPhones, verify in Settings → General → About that "iCloud Account" shows no linked email.

Step-by-Step IMEI Check Process for Facebook Marketplace

  1. Get the IMEI from the seller in Messenger chat (ask them to dial *#06# and screenshot it).
  2. Visit imeicheckpro.com/free-check and enter the IMEI — verify model and brand match exactly.
  3. Run a full premium report for blacklist, iCloud lock, and carrier lock status.
  4. At the in-person meetup: power on the phone, insert your SIM, confirm it connects to the network.
  5. For iPhones: go to Settings → General → About and verify "iCloud Account" is blank or signed out.

What If the Phone Fails Your IMEI Check?

Walk away. Do not negotiate a "discount" on a blacklisted or iCloud-locked phone — there is no legitimate fix for a blacklisted IMEI in most countries, and iCloud-locked iPhones cannot be unlocked without the original owner's Apple ID. Report the listing to Facebook using "Report Listing" and select "Counterfeit or stolen goods."
