How to Check Apple IMEI Before Buying a Used iPhone (2026 Buyer Guide)
Buying a used iPhone can save you hundreds of dollars — but only if the device is actually yours to use. A single bad IMEI report, an active Find My lock, or a carrier blacklist flag can turn a great deal into an expensive paperweight.
This guide walks you through exactly what to check on an Apple IMEI before you meet a seller, what to verify in person, and which free tools (including Verimei's Apple IMEI checker) give you the fastest answers.
Why the Apple IMEI Matters More Than the Price
Every iPhone has a unique IMEI (International Mobile Equipment Identity) — a 15-digit number tied to that exact handset. Carriers, Apple, and global blacklist databases all use it to track:
- Whether the phone is reported lost or stolen
- Whether Find My iPhone is still active (iCloud lock)
- The original carrier and SIM-lock status
- Model, region, and warranty details
- Outstanding installment or contract obligations on some networks
Sellers know this. Scammers often rush cash deals, refuse IMEI checks, or show you a different phone than the one in the listing. Your job is simple: never pay until the IMEI checks out.
Step 1: Get the IMEI Before You Meet the Seller
Ask for the IMEI in the first message. Legitimate sellers will send it. If they refuse, walk away.
How the seller can find the IMEI
- Dial
*#06#on the Phone app — the IMEI appears instantly - Settings → General → About — scroll to IMEI (tap to copy on newer iPhones)
- Photo of the IMEI on the original box or SIM tray
On dual-SIM models you may see IMEI 1 and IMEI 2. Use IMEI 1 for most checks unless a tool asks for both.
Step 2: Run a Free Apple IMEI Check Online
Use a checker that reads live carrier and Apple-related signals — not just a basic model lookup.
On verimei.com/apple-imei-check you can run:
- iPhone Full Info — model, color, capacity, SIM lock, warranty, IMEI2, and region (takes 10–20 seconds)
- iPhone Full Info (Fast) — model, Find My, iCloud status, and core device details in under 15 seconds
For iCloud-specific checks, also see Apple iCloud & Find My check and Lost / Stolen status.
What you want to see
| Check | Good result | Walk away if… |
|---|---|---|
| Find My / iCloud | OFF before handover | ON and seller won't sign out in front of you |
| Blacklist / Lost | Clean, not reported | Lost, stolen, or blacklisted |
| SIM lock | Unlocked or matches your carrier | Locked to a carrier you don't use |
| Model match | Matches listing (e.g. 256 GB Pro Max) | Wrong model, region, or capacity |
| Warranty | Active or clearly disclosed if expired | Seller claims "new" but warranty started years ago |
Step 3: Compare IMEI on the Physical Phone
When you meet the seller, dial *#06# again. The number must match what they sent online and what appears on the box (if available).
Red flags:
- IMEI on screen ≠ IMEI in chat
- Box IMEI ≠ phone IMEI (reboxed or swapped device)
- Phone is activation-locked at setup and seller says "just reset it"
Step 4: Confirm Find My Is OFF (In Person)
An IMEI check can show Find My status, but you must still confirm on the device:
- Open Settings → [Seller's name] → Find My → Find My iPhone
- It must be OFF, or the seller must sign out of iCloud while you watch
- After sign-out, go through setup until the home screen — no Activation Lock prompt
Never accept "I'll remove it later" or "it's off but still shows ON in the cloud." If Find My stays ON after payment, you may be unable to use the phone.
Step 5: Test Cellular, SIM, and Basic Functions
Bring your own nano-SIM or eSIM QR. Verify:
- Calls and mobile data work on your network
- No "SIM not supported" or permanent "No Service" (can indicate blacklist)
- Face ID / Touch ID, cameras, speakers, and battery health look reasonable for the claimed condition

Common Used-iPhone Scams (and How IMEI Checks Catch Them)
1. iCloud lock after payment
Seller takes cash, then remotely locks the device via Find My. Fix: Confirm FMI OFF and complete setup before paying.
2. Financed phone with hidden balance
Phone works today; carrier blacklists it 60–120 days later when the seller stops paying. Fix: Check blacklist and carrier financial flags; prefer sellers with original receipt.
3. Wrong model / region
Listing says "US unlocked 256 GB" but IMEI shows different storage or a locked regional model. Fix: Full IMEI report before meeting.
4. Blacklisted stolen unit
Works on Wi-Fi only or dies when you insert a SIM. Fix: GSMA blacklist check before purchase.
5. MDM / corporate lock
Phone is managed by a company or school. Fix: Check Settings → General → VPN & Device Management; ask for business devices to be removed from MDM before sale.
Where People Buy Used iPhones — Risk Levels
| Source | Risk | Tip |
|---|---|---|
| Facebook Marketplace / Craigslist | High | IMEI check first; meet in public; cash only after setup test |
| eBay / Swappa | Medium | Use buyer protection; verify IMEI matches listing photos |
| Carrier refurbished | Lower | Still verify IMEI — replacements can have different serials |
| Friend / family | Lowest | Still check FMI and blacklist — accounts get forgotten |

Frequently Asked Questions
Can I check Apple IMEI with just the serial number?
Some Apple services accept serial numbers, but IMEI is preferred for carrier and blacklist databases. If you only have a serial, try Apple Serial Full Info — for phones, always get the IMEI before buying.
Does a factory reset remove iCloud lock?
No. Resetting does not remove Activation Lock. The previous owner must turn off Find My or remove the device from their Apple ID.
Is a clean IMEI enough?
It's essential but not sufficient. You still need Find My OFF, a matching model, and a working SIM on your network. Think of IMEI as the first gate, not the only one.
How long does an IMEI check take?
Fast checks often return in 5–15 seconds. Deeper reports (full carrier history, warranty, IMEI2) may take 10–30 seconds. That's still far cheaper than a locked phone.
Bottom Line
A used iPhone deal is only good if you can activate it, use your carrier, and keep using it next month. The Apple IMEI is your fastest way to verify that — before you hand over money.
