How to find out if an iPhone is used or stolen, the first thing to do to check if an iPhone is stolen is to get the IMEI code of the device. The IMEI code is a 15-digit code that uniquely identifies mobile phones and can be useful to find out if a device has been blocked following a theft report.
The IMEI code can be obtained directly from the iPhone by accessing the Settings section, tapping on General and then on Info.
Once you have obtained the IMEI code, you can find out whether the iPhone was stolen by contacting Apple customer support on 199.120.800 (the line is charged and is active from Monday to Friday from 9:00 am to 7:45 pm ) and asking the operator if the device to which the code corresponds is blocked or reported due to theft or loss.
Another valid solution to check if the iPhone is stolen instead is to open the appropriate Apple support page accessible by clicking here, enter the serial number of the device (it can always be found in the Info section of the iPhone) in the special text field and by clicking on the Continue button so that you can know the details of the warranty status of the device and view the date on which the product was purchased.
The MacRubato website can also be of great help in understanding if the iPhone has been stolen. It is an online database in which users can report the identification codes of the Apple devices that have been lost, so if looking for the serial number of your iPhone some matches are found and it is very likely that you find yourself having to do with a stolen iPhone.
