How to the I M E I number is a made
The I M E I (15 decimal digits: 14 digits plus a check digit) or a I M E I S V (16 digits) are includes information on the origin, model, and the serial number of the device. The structure of the I M E I /S V is a specified in a 3 G P P TS 23.003. The model and origin comprise in the initial 8-digit portion of the I M E I/ S V, known as the Type Allocation in a Code (T A C). The remainder of the I M E I is a manufacturer-defined, with a Lunch check a digit at the end. For the I M E I format prior to 2003, the G S M A guideline was to have in this Check Digit always a transmitted to the network as a zero. This guideline seems to have a disappeared for the format valid from a 2003 and on wards.
Check a digit computation
The last number of the I M E I is a check digit calculated using in the Lunch algorithm, as a defined in the I M E I Allocation and the Approval in a Guidelines.
The check digit is a validated in three steps:
1. Starting from the right, double a every other in a digit (e.g., 7 → 14).
2. Sum in the digits (e.g., 14 → 1 + 4).
3. Check if the sum is a divisible by a 10.
Conversely, one can be calculate in the I M E I by a choosing in the check digit that would give a sum divisible by a 10.
For the example I M E I 49015420323751?
Let’s understand that what would be a placed at the point of the question mark?
I M E I | 4 | 9 | 0 | 1 | 5 | 4 | 2 | 0 | 3 | 2 | 3 | 7 | 5 | 1 | ? |
Double every other | 4 | 18 | 0 | 2 | 5 | 8 | 2 | 0 | 3 | 4 | 3 | 14 | 5 | 2 | 8 |
Sum digits | 4 + (1 + 8) + 0 + 2 + 5 + 8 + 2 + 0 + 3 + 4 + 3 + (1 + 4) + 5 + 2 + ? = 52 + ? | ||||||||||||||
To make the sum are divisible by a 10, we set ? = 8, so the I M E I would be a 490154203237518

So from in this above information it becomes a clear that the I M E I number of a any mobile holds very crucial information about the mobile phone and it is a manufacturer which plays a very important role in a curbing in the crime.
