Since 2004 the standard format for the IMEI code is AA-BBBBBB-CCCCCC-D. The initial two portions called A and B are known as the type allocation code or TAC, and they are related to the manufacturer as well as the model of the device. For instance, the Samsung Galaxy S2 uses 35-853704 while the iPhone 5’s TAC is 01-332700. The portion of the number called C is a serial number which is unique to the handset and is defined solely by the manufacturer. The final number is a checksum which is used to verify the entire string.
