How to find the serial number on your iPhone

Need to find the serial number of your iPhone? Read along for how to locate it in a few simple steps.

With modern iPhones, all text has been removed from the back of the device and lives digitally in settings (IMEI numbers can still be found on SIM trays but not serial numbers).
