Our reader already know we have an in-depth VIN decoder for Porsche models, so this post is all about knowing what the VIN range for each model year of Porsche 928. Some important notes for the Porsche 928 VIN researchers out there are noted below.
Firstly, for the 1978, 1979 and 1980 model years, the VIN is unique, when for only those 3 years a 10-digit VIN format was used. From 1981 model year onward, the new 17-digit Porsche VIN format was standardized per ISO 3833. Like the rest of the range, the first thing to understand is that Porsche 928 models were separated into types, based on country. There was Type US (United States and Canada) and RoW (Europe and Rest of World).
Where to find Porsche 928 VIN
To find the VIN on any 928, there are 4 primary places to look:
Left-side door jamb near door latch, adhesive applied label (Type US)
Left-side A-pillar under windshield, stamped plate (Type US)
Front-side under hood near where hood latches, stamped plate riveted to chassis (Type RoW)
Right-side inner fender wall, stamped into chassis (All Types)
To be sure, we recommended using the VIN plate on the inner fender wall since this is the only permanent VIN located on all 928 cars.
