We decided to create this guide to VIN, Engine and Transmission numbers for the 964 Porsche because we found it hard to get access to this information online.
Our easy to use guide should help you find what you need quickly. For more information about the Porsche 964, please check out our Ultimate Guide to the Porsche 964 page.
The first part of this appendix provides the Vehicle Identification Number (VIN), engine and transmission code breakdowns. From this information it will then be possible for a potential 964 purchaser to determine the validity of the VIN when doing a pre purchase inspection.
We went to great effort to ensure our data is accurate but as always we recommend that you check elsewhere too because errors do happen and getting reliable data from that era isn’t easy.

Porsche 964 VIN Numbers
The easiest way to correctly identify a 964 is to check the vehicle identification number (VIN). The VIN is a 17 digit international code. The VIN used by Porsche for the whole 964 series is the international 17 digit system.
There are two VINs for the 964 Porsche:
- Rest of the world (ROW). VIN identifies the 964 as being built to ROW specifications. Example: WPOZZZ96ZKS401786 = 1989 Carrera 4 Coupe.
- USA VIN (USA). The USA VIN identifies the 964 as being built to US specifications. Example: WPOCB2969RS465274 = 1994 Speedster.
Where to Find the VIN in a 964 Porsche:
- Rest of the world (ROW). The VIN is found on a data plate, installed in the luggage compartment attached to the right front inner fender. It is very near the right headlight assembly.
- USA VIN (USA). The VIN is found on a plate attached to the left front A pillar and can be viewed from the outside through the windshield.

*1 = RS America, 2 = US Coupe with airbags, 4 = US Targa with airbag, 6 = US Cabriolet with airbag. Digit 13 also provides version identification but can only be used for a specific model year. The numbers were changed around so a 5 in 1989 may not be the same as a 5 in 1994.
Porsche 964 Engine Number Codes
The engine number is located on the engine block, on the right side of the crankcase next to the fan housing. The engine code consists of 8 digits and is the same for all versions. Example:
- 62K86401 is an M64/01 engine installed in a 1989 Carrera 4 (normally aspirated).

Note: Digit 4 is exclusive to Tiptronic models. In model year 1991 this number became a 5. So from this model year onwards the M64/02 engine for the Tiptronic could be identified separately.
