Have you ever wondered what the letters stand for in an iPhone’s serial number? Whether you answered yes or no, the truth is that the code actually contains some pretty interesting information about the handset.
The folks over at OSXDaily have just published a legend of sorts that breaks down what each set of letters in an iPhone’s serial number mean. You can tell what size the device’s hard drive is, and even when it was made…
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.
Keep in mind that this pattern of serial numbers only works for the GSM iPhone 4. The structures for serial numbers on other iPhone models like the 3GS and 4S are fairly similar, but the above legend isn’t 100% compatible with those devices.“Serial numbers come in the form AABCCDDDEEF which can be read as follows:
For example, the serial 79049XXXA4S is from factory 79 (presumably Foxconn), was manufactured in the 49th week, and is a black 16GB iPhone 4.”
- 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
While this tip won’t likely change your life, it’s cool to look and see when your handset was made. If your week number reads anywhere between one and four, it means your iPhone was apart of the initial production run. That’s kinda neat, right?
