Method of distinguishing authenticity with mobile phone

1. First, look at the S/N code of the serial number label from the outer packaging, which is the product serial number. Product serial number is a concept introduced to verify the "legal identity of products", which is used to protect the legitimate rights and interests of users and enjoy legal services; A set of genuine products only corresponds to a set of product serial numbers.

The 6th to 10 bits of the SN code are the date of production, and the 6th and 7th bits represent the year, for example, Figure 20 above indicates 2020; The eighth place is the month, represented by the numbers 1-9 and a, b and c, where a, b and c respectively represent 10,1,65438+February; Number 9 and 10 are days. So according to this SN code, we can know that the production date of this mobile phone is March 20th, 2020. Look at the date 2020.03 in the triangle box in the lower right corner of the serial number label, and the month is consistent with the factory date (it should also be noted that if the production date is after the 25th of each month, the month in the triangle label will be displayed to the next month, which is also within the normal range). If other months do not match, it can basically be concluded that it is a refurbished machine.

2. Open the dial of the mobile phone and enter *#06# to see if the serial number of the mobile phone matches the serial number and SN code on the box.

3. There is a blue network access license on the back of the mobile phone (the 5G version is green), the second line (00-0000-000000) is the license number, the third line is the device model, and the bottom line is the scrambling code.

Then, the browser searches for "Internet card inquiry of the Ministry of Industry and Information Technology" and clicks on the authenticity inquiry (the warranty inquiry in the lower right corner of the homepage of WeChat official account has a URL link, which can be accessed directly with one click):

Enter the license number of the network card in turn. The model displayed in the "Device Model" drop-down list is the correct model, which should be consistent with the information in the second line on the signboard. If it is inconsistent, then your network access permission sign information is false; If they are the same, please enter the third line of information on the logo in the "Scrambling Code" input box, enter the IMEI number of the mobile phone with the logo in the "IMEI Number of Mobile Phone" input box, and click Verify.
