  • What Your iPhone's Serial Number Really Means



    The seemingly random grouping of numbers stamped on the back of your iPhone called a serial number actually means something according to OSX Daily.

    OSX Daily has published a guide that breaks down what the dutch all those numbers actually mean. From the serial number owners can tell what week their device was manufactured, the hard drive size, the production year and even the factory and machine ID.

    • 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




    Older models like the 3GS have a slightly different reference model changing the letters associated with hard drive size etc. The serial numbers for the iPhone 4S and iPhone 4 CDMA versions donít follow this patter either. OSX Daily issued the following list of devices that follow the above format.

    • 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)
    While this wonít help you do anything new with your iPhone, itís interesting to know exactly what goes into the construction of a serial number.

      I don't get all the negativity here. But if you really need someone to break it down for you... this isn't news. It's just an interesting tidbit that most people aren't aware of. Everyone knows what serial numbers are. Calm down geek.

      According to this, my white iPhone 4s was made in 2009. That doesn't seem very possible.

      Edit: never mind. I read further.

      Sigh, not every company that uses serial numbers uses them in this fashion.

      Of course they do. As he/she said that's the whole point of serial numbers. They obviously don't have the same lenght, format and algorithm across manufacturers but the concept remains the same.

      For anybody interested in that info for all Apple products:

      Funny how there is a serial number for each phone but when your phone is stolen apple can't do anything a out it. You can erase and restore using someone else's apple ID but serial number is still the same.

      I mean sure, it's not news worthy but it's good to know and it should be in another section of MMi.

      Do you even own an iPhone?

      "The seemingly random grouping of numbers stamped on the back of your iPhone called a serial number actually means something"

      Where exactly is that again?

      "Hard drive size?" Seriously? Follow the lead of the one who you are quoting: STORAGE. It's a catch-all for HDD, SSD, NAND, etc which still doesn't confuse with system memory.

      iPod touch follows it about the same but there are a couple of differences. Mine for example was made on a Wednesday.
