The next 2 digits (FAC) are the final assembly number (only present in early models), which represents the final assembly code. The last 6 digits (SNR) are serial numbers, representing the production sequence number. The International Mobile Equipment Identity Code is generally affixed to the back of the fuselage and outer packaging, and is also stored in the phone's memory.
