The IMEI number or in other words International Mobile Equipment Identity is a unique 15-digit code that precisely identifies the device with the SIM card input.
Why IMEI number is important?
The SIM card is associated with the user and can be swapped from phone to phone, a method is needed to keep track of the hardware itself, and that’s why the IMEI was developed.
The Structure of an IMEI Number
IMEI numbers either come in a 17 digit or 15 digit sequences of numbers. The IMEI format currently utilized is AA-BBBBBB-CCCCCC-D:
- AA: These two digits are for the Reporting Body Identifier, indicating the GSMA approved group that allocated the TAC (Type Allocation Code).
- BBBBBB: The remainder of the TAC (FAC)
- CCCCCC: Serial sequence of the Model (SNR)
- D: Luhn check digit of the entire model or 0 (This is an algorithm that validates the ID number) (CD)

Why making IMEI number public is not safe?
If someone has your IMEI, he/she can easily spoof their original IMEI with yours. By doing this he will be able to change the hardware information of his/her cellphone like device name, model etc. And tracking that device will become more harder. Changing IMEI isn’t a big deal and if that device is involved with any illegal activity, by tracking the IMEI number police might knock at your door!
