How to find your own mobile phone verification code?

IMEI (international? Cell phone? Equipment? Identity) is the abbreviation of international mobile equipment identification code, which is an "electronic serial number" consisting of 15 digits. It corresponds to each mobile phone one by one, and the code is unique in the world. Every mobile phone will be given a unique group number in the world after assembly, and this number will be recorded by the manufacturer from production to factory.

Press *#06# on your mobile phone and an IMEI code will appear. The first 6 digits (TAC) are "model approval numbers", which generally represent models. The next two digits (FAC) are the "last assembly number", which generally represents the place of origin. The 6-digit number (SNR) is followed by the "serial number", which generally represents the production serial number. Finally, 1 bit (SP) is usually "0", which is a check code and is reserved for the time being.

For example, the IMEI of a GT-I9308 mobile phone of Samsung is 355065? 05? 33 1 100? 1/0 1。 Where 355065 is TAC, 05 is FAC, 33 1 100 is SNR, 1 is SP, and 0 1 is the software version number.

The IMEI code is attached to the sign on the back of the mobile phone and read and write in the memory of the mobile phone. It is also the "document" and "ID number" of the mobile phone in the manufacturer.
