How Old Is My Phone

A question frequently asked by phone users is: How old is my phone. In this article, I will show you how to check your phone's birthday. Hope this trick is useful for you!

1.Check How Old Your Phone Is with SN Code

Firstly, we need to know about serial number. A serial number (SN) is the unique identifier of the item. For a mobile phone, the SN code is its ID card with its date of birth on it.

Here is a quick way to check the SN code of your smartphone: Open the dial pad on your phone, and enter the magic characters *#06#.

Now, the IMEI, MEID and SN codes will be displayed on your phone screen.

These are important information of your phone, don't rashly share these codes. Here I use a string of characters as an example of SN code: 2NSDU20430123456.

The sixth and seventh characters represent the year of manufacture of your phone. In the given example, the sixth and seventh character is 20, which means this phone came out in 2020.

Likewise, the eighth character represents the month, and the ninth and tenth characters represent the day. And 430 means this phone came out on April 30.

You may be wondering how the SN code uses one character position to represent 12 months. Actually, it uses letter A to replace 10-October, B for 11-November, and C for 12-December.

A small quiz: Try to identify the birthday of the phone with this SN number: 1A2BC21B02123456.
