    If you’re looking for your iPhone’s serial number, it can be found on its box’s ESN sticker or in iOS by going to Settings > General > About.

    “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 (not the same as UDID)
    EE = Color of device
    F = Size of storage, S is 16GB and T is 32GB
    For example, the serial 79049XXXA4S is from factory 79 (presumably Foxconn), was manufactured in the 49th week of 2010, and is a black 16GB iPhone 4.”

    Keep in mind that this pattern of serial numbers only works 100% for the GSM iPhone 4. The structures for serial numbers on other iPhone models like the 3GS, Verizon iPhone 4 and all 4S models are similar, but the above legend isn’t completely compatible with those devices.

    The factory code indicates which factory produces the iPhone, and as almost all iPhone is manufactured in China, most if not all factories are located in China. There is no leaked mapping information that identifies which factories or plants to the possible factory and machine ID, such as 6Q, 79, 7R, 7S, 7T, 7U, 7V, 84, 85, 86, 87, 88 and more.
    One interesting first two digit iPhone serial number that stands out is 5K, which has been widely believed to be indicating a refurbished iPhone (reconditioned iPhone). You won’t get a new iPhone with serial number which starts with 5K. The “5K” refurbished iPhone will only be given if you send in your iPhone for repair or exchange and get a replacement iPhone. However, depending on your luck, especially during the initial launch of new iPhone model, you may or may not get an iPhone with “5K” serial number as replacement though.

    While the last 3 digits of iPhone serial number can be read as following:
    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)

    Strange,

    My GSM 4S does not resemble any of these characteristics in it's serial number.
    :confused:

    For example, my 3rd digit on my SN is 9

    Thank you but my 4S is nothing like this. I know you said the 4S might be a little different but I don't see how it's related at all. Am I missing something?

    Updated this a bit, so things are more obvious. I am looking for info on the 4S, but there doesn't appear to be much out there.
