What is the ID and why not use the serial number?
The ID is used for convenience so the owners and finders do not have to use the serial number. The ID is generated automatically to make it easier on the owner during registration. It is also easier for the finder to see as the serial number is very small and may be hidden by certain accessory products. However, we allow the owner to register their serial number as well. This gives the finder an option of using the ID or the serial number when they report the phone.
