How to check if an iPhone is stolen

What does it mean, in short?

An iPhone can be risky even if it looks flawless. Problems usually come from unclear origin, an iCloud lock, network restrictions or mismatches between the IMEI, the box and the Apple Account. When you buy second-hand, a good decision rests on the specific device, not on the promise in the listing.

How do you decide quickly?

If the seller will not fully erase the phone and set it up in front of you, the deal is not safe enough.
If the iPhone asks for someone else’s account after a reset, the problem is serious and verbal explanations do not fix it.
If the IMEI, serial number and model do not match each other, treat the case as high risk.

What are the steps?

Step 1
Ask for the IMEI and serial number before you meet
This lets you check the device in advance and reduces the risk of relying only on an on-the-spot demo.
Step 2
Check that the seller can turn off Find My and sign out
On a legitimate iPhone, the seller should be able to sign out of their Apple Account and allow a full reset without hesitation.
Step 3
Compare the IMEI in Settings with the box and the proof of origin
If the values differ, do not continue until you understand exactly why. A lack of consistency is one of the most useful warning signs.
Step 4
After the reset, check activation
The best practical test is to see whether the phone can be set up without asking for the previous owner’s account.

What can go wrong if you skip the check?

You may buy an iPhone that asks for someone else’s account right after a reset and becomes unusable for you.
You may take on a phone with theft signals or unclear origin that is hard to account for later.
You may mistake an iPhone that works on the surface for one that is safe to buy, while the lock only shows up at setup or after a SIM change.

When is the Codat report relevant?

When you are buying an iPhone remotely and want to validate the device before travelling or paying.
When you want context on blacklist status, identifiers and other signals you cannot see from the outside.
When you need a report on the specific iPhone checked, not an assumption about all similar iPhones.

The Codat report supports your decision about the specific device that was checked. It does not support general claims about every phone of the same model, brand or category.

Limits of this guide

A result describes the status seen in the checked source at the time of the query; the status can change later.
A remote check does not replace a controlled reset, a hands-on test and checking the paperwork before you pay.
Activation Lock and blacklist status are different signals; a clean result in one source does not automatically prove legitimate ownership.

Frequently asked questions

If the iPhone turns on, does that mean it is safe?

No. An iPhone can turn on normally and still have Activation Lock, origin problems or network restrictions.

What is the most important hands-on check when you meet?

A full reset and activation without the previous owner’s account remain decisive checks, especially together with validating the IMEI.

Does the Codat report tell me whether every iPhone of that model is safe?

No. The report covers the specific iPhone checked and cannot support general claims about every device in the same range.
