The serial number would be assigned by the phone manufacturer - Motorola, Samsung, Apple, etc. - when they build the device. This serial number is not used for call routing. It is used for warranty work and stuff like that.
I think you would probably need the ICCID number of the SIM card to do what you're talking about. This number uniquely identifies the phone on the cellular network. It is used when routing calls to the phone. The ICCID number stays with the SIM card, not with the phone, if the two are separated. Your cellular service provider registers this ICCID number on their network when they activate your phone.
