IMEI, International Mobile Equipment Identity, is a unique number used to identify iDEN, GSM, WCDMA, and 3GPP mobile phones, and also some satellite phones. A phone majorly has an IMEI number; however, dual SIM phones have two IMEI numbers.
The IMEI is specifically used to identify the device and does not have any semi-permanent or permanent relationship with the subscriber. GSM networks use the number to identify devices that are valid. The number can, therefore, be used to prevent a stolen phone from having access to the network in that country.
IMEI numbers come either in a 15-digit or 17-digit strings of numbers. The IMEI format currently being in use is AA-BBBBBB-CCCCCC-D:
AA: These digits belong to the Reporting Body Identifier, which indicates the GSMA-approved group that issued the Type Allocation Code (TAC).
BBBBBB: This is the remaining part of the TAC (FAC)
CCCCCC: This is the model's Serial sequence (SNR)
D: This serves as the Luhn check digit of the entire model. It is an algorithm which validates the ID number (CD).
