Where to look at the serial number of the iPhone

We all know that there are many ways to check the serial number to see the warranty of the iPhone, such as Apple's official website, third-party software and the ** of querying the serial number, etc., not only that, but now we can find it on a lot of WeChat***, but in fact, we don't have to be so troublesome.

I shared with you a way to know the origin and production date of your iPhone without using any third-party platform without using any third-party platform.

How to tell the place of origin?

There is no doubt that the world's iPhone iPad is made in China. Foxconn has many factories in mainland China, and the places used to produce iPhones are mainly concentrated in Shenzhen, Chengdu and Zhengzhou.

The first letter of the iPhone serial number, starting with C for Shenzhen, D for Chengdu, and F for Zhengzhou. As for the origin of apples, there has been a saying that Shenzhen is the best in quality, followed by Zhengzhou, and Chengdu is the worst, but it is believed that such a statement has no scientific basis and is not credible.

After looking at the place of origin, let's take a look at how to know the production date of your mobile phone by the serial number:

The fourth digit of the serial number represents the year of production and is represented by 20 letters (excluding a, b, e, i, o, and u from the 26 letters), note that it is rounded semi-annually. where p represents the first half of 2015, q represents the second half of 2015, r represents the first half of 2016, s represents the second half of 2016, and so on.

The fifth digit of the serial number is represented by numbers (i.e., 1 through 9, minus 0) and letters (26 letters minus a, b, e, i, o, u, s, and z), a total of 27, representing the number of weeks, starting from 1, counting the numeric female numeric female, every six months. For example, the serial numbers N1 and N9 represent the first and ninth weeks of production in the second half of 2014, respectively.

It is important to note that 1 to 9 represent weeks 1 to 9, followed by c, which represents week 10, and so on.

Specific example: The serial number of the iPhone 6 in the picture above starts with D, which means that it is made in Chengdu, and the fourth serial number is N, which represents the factory in the second half of 2014, and J represents the fifteenth week, so this machine is the machine produced in Chengdu and produced in the fifteenth week of the second half of 2014. To be more precise, it left the factory in mid-October 2014.

It takes a while for an iPhone to reach the end user from the factory, so the difference between the factory date and the first activation time is generally about a month, which is a normal situation, and you can try it with your own iPhone!

Find it in just a few steps.
