What year is your 911?decode your chassis number.
This tool currently covers the earliest 911s — 1964–1966. Later years use different numbering systems we're still cross-checking before we publish them here.
How to read an early 911 chassis number.
Porsche's earliest 911s used plain 6-digit sequential numbers, with an "S" suffix marking the higher-performance 911S. Base and S cars shared the same number block in a given year, distinguished only by that suffix.
1967-1968 used a much more fragmented numbering scheme across many more trim variants (911T, 911L, 911E, 911S, and export-market versions of each), and our sources for those exact ranges don't agree closely enough yet for us to publish them as accurate.
These years use a transitional format and then the newer 17-character VIN standard. We haven't done the research on this range yet — it's next on our list.
| Model year | Coupe (base & S) | Targa (base & S) |
|---|---|---|
| 1964 | 300001-300235 | — (Targa not yet offered) |

Early 911 chassis numbers, answered.
Where do I find the chassis number on an early Porsche 911?
On these early cars it's stamped on the front luggage-compartment floor near the spare tire, and on a plate visible when you open the front trunk. It's a 6-digit number (sometimes with an “S” suffix for S-model cars) — not the 17-digit VIN format used on later cars.
Which model years does this 911 chassis decoder cover?
This tool currently covers the earliest 911s — 1964–1966. Later years use different numbering systems we're still cross-checking before we publish them here.
How is an early 911 chassis number structured?
Porsche's earliest 911s used plain 6-digit sequential numbers, with an “S” suffix marking the higher-performance 911S. Base and S cars shared the same number block in a given year, distinguished only by that suffix.
Why aren't 1967 to 1979 cars supported yet?
1967-1968 used a much more fragmented numbering scheme across many more trim variants (911T, 911L, 911E, 911S, and export-market versions of each), and our sources for those exact ranges don't agree closely enough yet for us to publish them as accurate.
How accurate is the year this decoder gives me?
The 1964-1966 ranges come from a single well-documented chassis-number reference, but unlike our 912 decoder we haven't yet cross-checked these specific ranges against multiple independent real-car examples. Treat the year as a strong indication, not a certainty, and for anything valuable call the shop and we'll help you track down a Kardex record.
