Part 1. What is iPhone IMEI

IPhone IMEI (International Mobile Equipment Identity), is a unique serial number of each iPhone, which can identify a GSM or UMTS mobile phone. In fact, the iPhone IMEI is very similar to the ID card. They all indicate the only one among the whole, which can not mistake or misidentify the thing.

In general, iPhone IMEI has 15 decimal digits, which includes information of the origin, model and serial number of the device. The first 8-digit part of the iPhone IMEI represents the model and origin, which is known as the TAC (Type Allocation Code), followed by the 6-digit portion called SNR (Serial Number), whose range must be allocated by the Reporting Body, for the device manufacturer can assign the number range to its individual mobile stations. There is a Check Digit using the Luhn Algorithm at the end, as defined in the IMEI Allocation and Approval Guidelines to help guard against the possibility for incorrect entries to the CEIR (Central Equipment Identity Register) and EIR (Equipment Identity Register). Besides, there is also a 16-digit variation that includes information of the device's software version, known as the IMEISV (International Mobile Equipment Identity Software Version).

Prior to 2002, the iPhone IMEI consisted of four parts, TAC, FAC, SNR and the FAN (Final Assembly Number). The TAC was six digits long, and was followed by a two-digit FAC, which was a manufacturer-specific code to show the location of the device's construction. From January 1, 2003 until April 1, 2004, the FAC for all phones was 00. After April 1, 2004, the FAN ceased to exist and the Type Allocation Code increased to eight digits in length.
