How to Decode iPhone Serial Number

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
  • 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)
E00 (iPhone 4 White 32GB) – Courtesy IyonUK
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.

But no worries, OS X Daily reader Michael points out that this website decodes the serial number of not only previous generation iPhones but also iPhone 4S  (except it is wrongly reporting that our iPhone 4S is the sixth generation iPhone).

Let us know if you were able to decode your iPhone’s serial number.

    E00 – White iPhone 4 32Gb. Dunno about CDMA or not.

    • IyonUK

      Just checked. Is GSM.

    Thanks for the information. Very helpful.. :)

  • Pascal_S

    The CCC field seems to contain 3 uppercase letters, hence with a maximum value of 26**3 = 17’576.
    I am suprised to see that one factory could not make more units in one week (for a single model although).

  • http://zpaul2fresh8@gmail.com Paul

    Factory and machine numbers are 83 on mine. Made in the 27th week of 2010. anyone know the factory identifications?

  • Moe

    Cool. Seems when I bought my iPhone 4, it was only two weeks old.

  • Lawrence

    I have a white, iPhone 4S with 64GB. The third digit in my serial number is a 9. 2009?! That doesn’t make sense.

  • Louis

    This is not always correct. I have a 3Gs which starts with 5K which means refurbished. (my phone original fell and broke). The next 3 digits are 021 which is week 21 of 2010. However, by that week Apple was already producing the New Bootrom 3Gs but mine has the Old Bootrom. The only thing I can think of is that this is NOT the manufacture date but the refurbish date which leaves you in the dark when and where you phone was manufactured.
