We all know, the iPhone’s serial number includes the week it was manufactured, factory id, color, size of the storage and other informations on your iPhone. But many people only know a rough, does not know the details of the method to decode it. Here we teach you how to decode the iPhone 4S Serial Number. Of course, also used for other versions of the iPhone.

First, you need to locate the Serial Number. Go to 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
EEF = iPhone model, color of device and size of storage
VR0 (iPhone 2G Silver 4GB) WH8 (iPhone 2G Silver 8GB) 0KH (iPhone 2G Silver 16GB) Y7H (iPhone 3G Black 8GB) Y7K (iPhone 3G Black 16GB) 3NP (iPhone 3GS Black 16GB) 3NR (iPhone 3GS Black 32GB) 3NQ (iPhone 3Gs White 16GB) 3NS (iPhone 3Gs White 32GB) A4S (iPhone 4 Black 16GB) A4T (iPhone 4 Black 32GB)

For example, the serial 79049XXXA4S is from factory 79 (presumably Foxconn), was manufactured in 2010 in the 49th week, and is a black 16GB iPhone 4.

Note: It’s not clear what’s the last three characters for all the white iPhone 4 models. So if you have one do let us know.

Unfortunately, Apple has changed the serial number generation with the CDMA iPhone 4, so this is not applicable for the CDMA iPhone 4 and iPhone 4S.

Now you can decode the serial number with this website, which can decode not only previous generation iPhones but also iPhone 4S.
