In fact, the verification of mobile phones is not only based on the serial number to identify 3 codes and 1, but some Hong Kong versions support less than 3 codes and up to 2 codes. Therefore, there are other aspects to verify the mobile phone:
1 Look at the serial number. The serial number of a mobile phone is unique to every mobile phone just like the ID card of the mobile phone. Generally speaking, it can be used to judge whether a mobile phone is genuine or not. The judgment method is as follows: enter *#06# in the standby state of the mobile phone, and a string of numbers displayed by the mobile phone is the serial number of its motherboard. Then look at the IMEI number on the mobile phone box and take out the SIM card holder to see if they are all the same.
2 serial number information query. You can use Baidu apple 1 10, enter the serial number code to find the relevant information of the mobile phone, enter the serial number in the text box and click the "Query" button.
Drop a drop of water on the screen of the mobile phone to see if it will disperse. Apple mobile phone is made of special materials. Generally, dripping water on it will keep the shape of the water droplets and basically will not spread out. This is also a special case of Apple's mobile phone. If it is special, it can also be judged as a refurbished machine.
Refurbishment refers to the mobile phone that is disassembled and then assembled with other old spare parts, which is called refurbished machine. At present, it is mainly aimed at a series of mobile phones of Apple.

There are several ways to identify the authenticity of an Apple mobile phone:
1. The new iPhone battery has not been used. If the battery is found to have a long service life record, it is likely to be a refurbished machine. The method is to go to iPhone Settings-General-Power Settings to check the battery life;
2. Check the activation time. There is no activation time for the new iPhone. If there is, it is probably a refurbished machine, or at least it has been used by others, otherwise it cannot be activated;
3. Check the serial number. Every Apple computer has a serial number 1 1 (coded by letters and numbers), which can be queried in professional serial number query tools. When you buy a mobile phone, you should check whether the serial number of this mobile phone is correct in official website, Apple. If the serial number of this machine is cancelled on Apple official website after the motherboard has been replaced or repaired, the query "Sorry, this is the serial number of the replaced product" will appear.
