You've found an iPhone that looks like a bargain. The seller says it's refurbished, the photos are clean, and the price is low enough to feel smart but not so low that it screams scam. That's exactly the moment when most buyers make their biggest mistake. They check the screen, maybe the battery health, and skip the one detail that can tell you whether the phone is safe to buy.
That detail is the IMEI number.
If you want to know how to check iphone imei number properly, don't stop at finding the digits. Its value lies in using that number to check whether the iPhone is blacklisted, locked to a carrier, mismatched to the box, or still tied to someone else's account. For Australian buyers, that matters even more because a phone can look perfect and still fail on local networks.

Why Your iPhone's IMEI is Your Most Important Tool
A lot of second-hand iPhones look fine at first glance. The screen turns on, Face ID works, and the casing has only minor wear. None of that tells you whether the phone has a clean history.
The IMEI is the number that matters because it identifies the handset itself, not just the listing. In Australia, over 1.2 million mobile handsets were registered on the national database in 2023, which shows the scale of devices moving through the market, and failing to verify can leave buyers with a blacklisted phone, a problem affecting 15 to 20% of reported stolen phones annually according to 2024 Telstra data, as noted by this Australian IMEI check reference.
It's the phone's identity, not just a serial
Think of the IMEI as the iPhone's passport. It gives you a way to check whether the device matches the seller's claim and whether Australian carriers may block it.
That matters most when you're buying refurbished from marketplaces, local classifieds, or any listing where the phone's history isn't fully documented. A neat box and a polished frame don't prove much.
Practical rule: If a seller won't share the IMEI before payment, treat that as a warning sign.
A cheap deal can get expensive fast
An iPhone can be usable today and still become a headache tomorrow. If it's blacklisted, carrier-locked in a way you didn't expect, or linked to a mismatched box, your “deal” starts costing time, stress, and repair-shop conversations you never wanted.
For Australian buyers, the IMEI check is where a casual inspection becomes a proper buying decision. It's the fastest way to separate a refurbished iPhone with a clean history from one that only looks good on the outside.
Quick Ways to Find an iPhone's IMEI Number
The good news is that finding the IMEI is easy when the iPhone is working. The better news is that you can check it in more than one place, which helps you confirm the number hasn't been altered or misrepresented.
Use the fastest method first
If the phone is switched on and responsive, open the Phone app and dial *#06#. The IMEI appears on screen straight away.
This is the quickest in-person method because you don't need to unlock every menu. It's ideal when you're meeting a seller and want the number in seconds.
A good habit is to copy the number into Notes or take a photo of the screen with the seller's permission so you can run your checks carefully rather than rushing through them on the spot.
Check inside Settings
On a working iPhone, go to Settings > General > About. Scroll until you see the IMEI entry.
This is the software-based method I trust most during a device inspection because it also lets you compare the IMEI against the model name, storage, and other device details shown in the same menu. Apple standardised this path from iOS 7, which made the information easy to access without needing to inspect the exterior.
If the seller hesitates to let you open Settings and About, that's usually more revealing than anything the phone itself might say.
Look on the device or SIM tray
Some iPhones also show identifying information on the physical hardware. Depending on the model, you may find the IMEI on the SIM tray or, on older devices, printed on the back.
That physical marking is useful when the phone is partly set up, stuck at a setup screen, or you want another source to compare against what appears in software.
A quick visual guide helps if you're inspecting a phone in person:
- Dialler method: Best when the handset is active and you need the IMEI immediately.
- Settings method: Best for a fuller on-device check and matching specs.
- SIM tray or physical marking: Best as a backup when access is limited.
If you want to see the basics in action, this walkthrough covers the common retrieval methods and why Australian-specific checks matter afterwards.
Finding the IMEI When the iPhone is Off or Inaccessible
Sometimes the phone won't boot, is stuck on the Hello screen, or the seller says it's disabled. That doesn't mean you have to guess. You still have a few solid ways to pull the IMEI.
Read the box carefully
The original retail box usually has the IMEI on the barcode label. That's helpful, but only if you treat it as one piece of evidence rather than proof on its own.
Boxes get swapped. Devices get repaired. Labels can belong to a different handset than the one in front of you. If the box IMEI doesn't match the phone, stop and investigate before doing anything else.
Use Finder or iTunes
If the iPhone connects to a computer, you can often read its IMEI through Apple's desktop tools. On macOS Catalina 10.15 and later, use Finder. On older Macs and Windows PCs, use iTunes. For locked or disabled iPhones, this method is especially useful, and 31% of first-time users miss it because they need to click the device model name to cycle through the identifiers, according to this technical guide on retrieving IMEI from locked iPhones.
Use this order:
- Connect the iPhone to the computer with a cable.
- Open Finder or iTunes and select the device.
- Click the model name or identifier field until IMEI appears.
Check through your Apple ID account
If the device belongs to you, or the seller can legitimately access their account during inspection, you can check the IMEI through the device list at account.apple.com.
That method is particularly handy when the handset itself isn't easy to operate. It also gives you another source for comparison, which is exactly what you want in a cautious purchase.
Decoding the IMEI What This Number Actually Reveals
Once you have the IMEI, you've got more than a string of digits. You've got the key to the phone's identity.
What the IMEI identifies
At a practical level, the IMEI ties the handset to its hardware record. That's what lets checkers and carrier systems recognise the device as a specific iPhone, rather than just “an Apple phone”.
For buyers, that matters because listings are often vague or sloppy. Sellers get storage wrong. Colours are mislabelled. Replaced units are described as original. An IMEI lookup helps you pin the phone down to what it is.
What a proper lookup helps you confirm
A useful IMEI check can help you confirm:
- Model details: Whether the handset is the model the seller claims it is.
- Storage and variant: Helpful when a listing says one capacity and the device record suggests another.
- Carrier background: Whether the device may be tied to a specific network.
- Warranty-related clues: Whether there may be remaining manufacturer coverage or signs of replacement history.
Often, buyers make a simple but costly mistake. They find the IMEI and stop there. The better approach is to treat the number as a starting point and compare the result against the phone in your hand, the box, and the seller's listing.
The IMEI matters most when it contradicts the story you've been told.
A clean-looking phone with mismatched records is not a clean buy. A scruffy phone with consistent IMEI records can be the safer purchase.
Verifying IMEI Status The Crucial Pre-Purchase Check
This is the part that protects your money. Finding the IMEI is easy. Interpreting the phone's status properly is what separates a routine refurbished purchase from a painful one.
Australia's IMEI blacklisting system has real weight. It was enforced from 2015, and by 2024 had blocked over 500,000 stolen iPhones, while Australia's refurbished electronics market reached $1.8 billion in 2025, with iPhones making up 40% of that market, according to this report reference covering Australian IMEI blacklisting and market scale. With that many devices changing hands, a proper check isn't optional.
Blacklist status on Australian networks
Start with the question that matters most. Has the phone been reported lost or stolen, and is it blocked from Australian networks?
Australian buyers should use tools and checks that reflect local carrier and blacklist data, not just generic global results. A phone can pass a basic online lookup and still be a bad buy for Telstra, Optus, or Vodafone use.
What works well:
- Australian-focused IMEI checks: These are more useful for local buying decisions because they're more likely to reflect carrier lock and blacklist issues relevant here.
- Direct carrier confirmation: If the situation is unclear, checking with the carrier is often better than trusting a bare-bones IMEI result page.
- Cross-checking multiple records: One result alone can miss context.
What doesn't work well:
- A seller saying “it worked last time I used it”
- A screenshot with no live verification
- A generic clean result with no local network context
If you're comparing devices and want a benchmark for what a legitimate refurbished listing should feel like, reviewing a refurbished iPhone buying example can help you spot the difference between clear disclosure and vague resale language.
Carrier lock status
Carrier lock checks matter more in Australia than many buyers realise. A refurbished iPhone might be technically functional but still restricted to a network, or tied to an imported carrier arrangement that causes trouble once you insert your SIM.
A useful IMEI lookup should help you answer a simple question. Will this phone work cleanly on the Australian network you plan to use?
Activation Lock and ownership checks
An IMEI check doesn't replace a direct ownership check. You also need to make sure the device isn't still tied to the previous owner's Apple account.
Ask the seller to show that the iPhone is signed out of iCloud and no longer linked by Activation Lock. If they can't do that during inspection, don't assume you'll sort it out later. In practice, you usually won't.
Interpreting IMEI Check Results A Buyer's Action Plan
Raw IMEI results can confuse buyers because they dump out bits of status without telling you what to do next. The easiest way to handle them is to sort everything into green lights and red flags.
Green lights
A result is encouraging when the details line up across multiple places. The strongest method is to compare the IMEI in Settings, on the original packaging, and in the Apple ID device list. That multi-source approach is the most reliable, and when used systematically it has a success rate exceeding 94% for detecting fraudulent devices, as described in this guide on multi-source IMEI verification.
Good signs include:
- Matching records: The IMEI is consistent across the phone, box, and account record.
- Clean status: Nothing suggests blacklist issues.
- Expected network behaviour: The phone appears usable on your intended carrier.
- Seller transparency: They let you inspect the device without rushing you.
Red flags
Some results should stop the purchase immediately.
| Result | What it usually means | What to do |
|---|---|---|
| IMEI on phone doesn't match box | Possible tampering, repair history issue, or swapped packaging | Ask for an explanation. If it's vague, walk away |
| Blacklisted status | Reported lost, stolen, or blocked | Don't buy it |
| Overseas or unclear carrier restriction | Possible compatibility headaches in Australia | Only proceed if the seller can prove proper unlocking |
| Activation Lock still present | Previous owner still controls the handset | Don't pay until it's removed |
A seller's story never outweighs a bad IMEI result.
When to walk away and when to negotiate
Walk away when the IMEI shows blacklist problems, active ownership locks, or unexplained mismatches. Those issues don't become harmless because the price is good.
Negotiate only when the result is mostly clean and the issue is limited to something the seller can prove and fix, such as documentation around a repair or network status. If you want to compare against a more transparent retail-style listing, this refurbished iPhone product example shows the kind of straightforward presentation buyers should expect.
Frequently Asked Questions About iPhone IMEI Checks
What if the IMEI on the iPhone and the box don't match
Treat that as a serious warning. It can mean the box belongs to another phone, the handset has been replaced, or the device history isn't clean. Ask for a clear explanation and supporting proof. If you don't get it, don't buy.
Can an IMEI be changed or cloned
Yes, mismatched or fraudulent IMEI situations do happen in the second-hand market. That's why a single lookup isn't enough. Cross-checking the IMEI against the phone, packaging, and account record is much safer than trusting one screen or one website.
What matters most for refurbished iPhone buyers in Australia
For Australian buyers, the key checks are whether the phone has local carrier locks with Telstra, Vodafone, or Optus, whether it's blacklisted on Australian networks, and whether it may be an imported device with hidden restrictions, as highlighted in this Australia-focused guide on carrier locks and network risks.
Is finding the IMEI enough on its own
No. Finding it is step one. The value comes from verifying what that number says about the phone's history, network status, and ownership.
