In case you are not aware, the serial number provides some interesting information about your iPhone, including the week it was manufactured and the factory id.
Folks at OS X Daily tell us that the serial number on the iPhone tells you the week it was manufactured, the factory where it was made and somethings which you already know such as the color and the size of the storage.
The first step is to locate the Serial Number. The easiest way to find it is to open your Settings app and navigate to General -> About -> Serial Number. You should also see the Serial Number in the Summary tab in iTunes when your iPhone is connected to the computer.
Serial numbers come in the form AABCCDDDEEF which can be read as follows:
- AA = Factory and machine ID
- B = Year manufactured (simplified to final digit, 2010 is 0, 2011 is 1, etc)
- CC = Week of production
- DDD = Unique identifier
