Serial Numbers
The breakdown of serial numbers for 912 by year according to
Dr. B. Johnson in The 911 & 912 Porsche. A Restorer's Guide to
Authenticity is:
| Year | Porsche (1) | Karmann (2) | Targa |
| 1965 | 350001-351970 | 450001-454470 | |
| 1966 | 351971-353000 | 454470-458100 | |
| 1967 | 354001-355601 | 458101-463204 | 550001-550544 |
| 1968 (3) | 12820001- | 12800001- | 12870001- |
| 1969 | 129020001-129023450 (4) | 129000001-129004280 | 129010001-129010801 |
Notes:
- Assembled by Porsche
- Assembled by Karmann
- Information incomplete for 1968 serial numbers.
- A couple of people have suggested that this series has vehicles
assembled by Karmann indicating Johnson's data is in error.
The owners manual describes where to find serial numbers on the 912.
In my case the desciption does not match reality in one case.
Vehicle Identification Number
There are 3 places to find the chasis number. This number is now
referred to as the VIN number and is the number that is on your
registration and/or title.
First is inside the front door. This one includes the paint code. In
my case 6608-G. 6608 is color - Aga Blue, and G is the manufacturer
of the paint, Glasurit.
| Under the hood to the left of the hood latch is the second tag which
includes the serial number, the model and some weights.
This label is interesting because the owners manual shows a different
position for it - behind the rear tire.
|
| Here is the area behind the rear tire. From front to back is the top
of the spare tire, the fuel tank which is molded to fit around the
spare, a cross member which has the serial number on the left and the
lid for the compartment designed for the gas fired heater.
|
| Here is the serial chassis number on the cross member shown in the
previous picture.
Obviously all three numbers should match - and they do in my car.
However, a lot of strange things can happen in 35 years.

| A note from Jouni Pollarinen:
Hi Dave
I found fourth place for a serial number !!
I am not sure if it is only for -68 models. But it's very
difficult place, so I just wondering maybe it could be good
place to look and see if everything is ok.
Its behind lower dash padding. So you have to unfit that
padding first. I put a picture, maybe that help you. And
thank god, thats not my car :-)
Yours Jouni
Thanks, and I have to believe there may still more serial numbers
stamped in the body work.

Engine Number
|
The engine number is stamped on the nose section of the case, below
the generator.
The case for the engine is a three piece assembly. The nose, and the
left and right pieces that hold the crank shaft. You can actually see
the parting line between the nose piece and the left half of the crank
case in this picture.
|
There are two more numbers visible on the left and right halves of the
engine case behind the generator stand. The left is the case serial
number. The one on the right is the model number of the engine.
The best discussion of these numbers is in the
Maestro's book, The Secrets of the
Inner Circle. and Johnson. Here is a synopsis of that data.
Note:
- Porsche did not provide ending numbers for 1968 and 1969.
- There are gaps in the numbers - do not infer production quantities from this data.
| Year | Starting | Ending |
| 1965 | 740001 | 744210 |
| | 830001 | 832090 |
| 1966 | 744211 | 750001 |
| | 832091 | 836000 |
| 1967 | 750001 | 756195 |
| | 836001 | 837070 |
| 1968 | 1080001 | 1080204 |
| | 1280001 | 1285700 |
| 1969 | 4090000 | 4097000 |
Transmission Numbers
|
Both the transmission type and serial number are
stamped on the bottom of the tranmsission case. The type is just
below the differential. It shows 902/1, the five speed.
|
|
The transmission serial number is on the bottom of
the transmission close to engine. The number is 234140.
