Porsche option/build codes
Every Porsche leaves the factory with a list of standard and optional equipment. Standard equipment is described by build codes and optional equipment by option codes. The codes are three or four character strings of numbers and letters. Back in the old days all the codes started with an M and they were called as the M-codes. Nowadays they start with an I. The codes are usually printed on stickers: one of these is added to the service book, but the second one changes location, depending on the specific model (under the bonnet, in the trunk or not available at all). If you’ve bought your car as new from the dealer, you probably know what options you selected, but with second hand cars, it’s unknown and decoding these codes without a proper manual is quite impossible, especially as Porsche has reused some of the codes for different equipment over time.
We have collected all the options for different models and model years so you can decode these magic numbers for your car. For early cars the number of options is usually very short, sometimes only a few lines, later cars are much more verbose in that area. For example an eighties Porsche might have just a couple of option codes, while a 996 Turbo with nothing really super fancy extras, has about 70 codes (most of them standard equipment build codes) .
