The difference between mobile phone serial number and IMEI

Mobile phone serial number: SN number (short for serial number), which is the number compiled by the mobile phone manufacturer. The numbering rules of each manufacturer are different, which can be changed and cancelled after generation.

IMEI number of mobile phone: 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. Once generated, it cannot be changed or cancelled.

You can compare the serial numbers of your mobile phone with those of other brands, and the results will definitely be different. However, imei numbers are all composed of 15, which is equivalent to one national standard and one international standard.
