IMEI is the unique number identification of a cell / mobile phone. All mobile phones have a unique number – therefore you would not find two with the same number.

Very informative post for all, please don’t forget to read & comments

Press the following on your mobile * # 0 6 # and the-international mobile equipment identity number appears. Then check the 7th and 8th numbers:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
x x x x x x x x x x x x x x x

To check your IMEI number, key in “*#06#” (star hash zero six hash) on your Nokia mobile phone’s keypad just as you would when you dial a phone number to make a call.

More detailed info. This only applies for phones after year 2004.
Format of IMEI is just like show below:
AA-BBBBBB-CCCCCC-D
AA-BBBBBB = Type Allocation Code (TAC)
CCCCCC = Serial sequence
D = Luhn check digit. (or zero if no checks)

From AA: you can know the Reporting Board – example 35 is BABT (British Approval Board for Telecommunications).
