How to determine your
Apple part number through the IEEE Code.
All Apple
logic boards and other sub-assemblies have what is known as an IEEE
code in the serial number. This IEEE Code is used to determine
exactly which computer the part is from. Typically the code is
three digits long and is in the last four digits of the serial
number. All
you have to is look at the last four digits of the serial number, on
some boards its the last three and others you drop the last digit and
use the preceding three.
So, for example,
in the picture above the serial number is
J555108UTURBA, the IEEE code is URB which cross references to a
661-3725 Power Mac G5 Dual 2GHz/2.3GHz PowerPC Logic board from the
Power Mac G5 (Late 2005). Of course only Authorized Apple Repair
Centers have access to the cross reference sheet so it's a bit
difficult to figure them out, we have compiled a database and can
figure it out for you so this is what we'll need.
You may also see an 820-xxxx-x number etched on the board, this is
actually the part number of the actual board without any components on
it. This enables a manufacturer to produce several boards with
the same etch by populating them with different components like a
faster CPU and assign different part numbers to them, the 820-xxxx
number is not always compatible.
How to determine my computer model
If you need to figure out the bulild of your computer you can check it
directly with Apple with the serial number. You can obtain the
serial number from the "About this Mac" under the Apple if your
computer is still working. If not, on most laptops it's on the
bottom or under the battery, iMac's are on the bottom, and Mac Pro's
are on the back.
Once you've located the serial number go to link below and type it in,
Apple will tell you the build of your computer, i.e. iMac 24-inch
(Early 2009), etc.
