Knowing the serial number of your iPhone can be very useful in several cases, especially to check the warranty status or to check the model of the smartphone if you buy it second-hand.
It is not always easy to know where to look for this famous serial number. On the object itself, you can see many symbols, without knowing exactly which make up the serial number of the iPhone.
Fortunately, Apple offers several options for finding this identification number. A good thing when the iPhone no longer turns on or the number on the object has been deleted.
From the system
If you still have your phone and it works, you can then consult the serial number of your iPhone from its screen. To do this, go to the phone settings, then "General" and select "Information". At the bottom of the page, you should see the watch serial number.
If for some reason you cannot access this information from your iPhone, you can still use the IMEI / MEID number. It is written on the phone which allows to note it, even when the iPhone no longer works. In addition, it has almost the same use as the serial number.
On iPhone 6s and later, this number is indicated on the SIM card holder.
For older iPhone, iPhone 6 and earlier, the IMEI / MEID number is listed on the back of the device. It is made up of 14 digits.
From iTunes
You can find your iPhone number from the iTunes software - although it will disappear. Once your phone is connected to your computer, launch the software and go to the "Summary" tab on your phone's account to view its information.
If you no longer have the device
The serial number - and IMEI / MEID number - can be viewed from the Apple ID page. Just log in with the Apple account linked to the smartphone and select it from the list of products displayed on its account. You should easily find the number by clicking on the iPhone in question.
Another option: the original packaging. The serial number is written on the barcode of the box.
