errm

i think your talking about the imei and serial numbers

the imei (international mobile equipment identifier) is what the phone uses to talk to the network, along with your sim card information, if your phone becomes barred its barred using the imei, and your stuffed

the other number is the serial number, this is used when you send the phone back for repair

later
