  • 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.

    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




    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.

    • 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)
    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.

      Is this worth waisting more of my time on here?

      How about a questionnaire on what people are enjoying on there new jail sprung devices? Or even some solid research on Cydia that isn't on every blog page already. With such a talented crew I find it strange that I question why I keep coming here and reading the same blog. Surely many people are after some hot relavent jail breaking info.
      With Cydia overflowing I hear no excuse for not having more interesting package or time savers being reviewed.
      Besides being lazy.

      So I have got a new i4s. As I bet 1/2 your viewing audience. What does my serial number mean? Wait i already know what i need. Says 2012 white 64gb. S, assembled in China.
      Ok i am lying but can only assume, hope so becouse that is what I purchased from Apple when they released this newest model lol.
      Who is this old info of use too lol?

      Wow. Sorry just my

      And a waist of three minutes.

      Since when does the word "news" automatically refer to "professionally educated journalism"? So absolutely nothing this site reports on is "news" to you?

      Knowing what each aspect refers to is interesting (even if most of the information hidden in the serial number has been reported about by MMi back in 2009) however the article is written in a tone suggesting the serial numbers were just random strings until recently unveiled by the source site and that Apple so cleverly hid this information under our noses. Perhaps some staff writers should read their own site.

      Yes, if apple could, they'd probably call in a swat team to find ur iPhone. It's not apples responsibility: they do not care lol

      Yes!! My phone was stolen last week and that person can do whatever they want. Apple said they couldnt do anything even tho it was registered to me.

      This. Apple could at the very least halt generation of SHSH blobs and push/activation certificates for reported stolen devices. While serial numbers and UDIDs can be changed, IMEI/MEIDs and ECIDs are not so easy... Apple knows this but apparently doesn't give a toot.

      Yeah, this is common knowledge I thought. Also, I can't recall the iPhone ever having the serial number on the back of it. Only place its actually printed on the phone is the SIM tray.

      Good info to know as a couple of weeks ago, I was trying to find out how to change a 3GS IOS 5 to the iPad bb so it could be unlocked.
      You need to know the date it was manufactured to see if it can be changed to iPad bb.
      Go to any jailbreak and unlock specialist and the first thing they do is check out the serial number.

      That doesn't make any sense. According to my serial number, my iPhone 4 was manufactured in 2010 during the 37th week. Week 37 is halfway through August. I got my phone in June, had it replaced in July, and have had the same phone since. Unless someone took my iPhone, backed it up, restored another iPhone with the backup, and swapped them, there's no way it was manufactured on the 37th week of the year.

      If the latest two models, the iPhone 4 and 4S donít follow this patter, then what's the purpose of posting this article in January 2012 ???
