Porsche 356 Chassis / Engine Numbers

This page contains internal and external links to sources of information about the numbers of the chassis and engines produced by Porsche AG during production of the Porsche 356. No source of information is completely reliable and the Porsche 356 Registry takes no responsibility for this information. Anyone considering entering into a financial transaction which depends on chassis or engine numbers should do their own due diligence.

This page also contains links to discussions of the topic of Matching Numbers and fraudulent practices which are sometimes associated with chassis and engine serial numbers. If Matching Numbers are important to you, you should read these discussions to educate yourself.

Finally, this page states the Porsche 356 Registry Position Statement Against Counterfeiting and Fraud.


Chassis and Engine Number Table

Brett Johnson is considered the expert in documenting every detail of the production numbers, models and running model changes of the Porsche 356.  Brett has generously donated some of the content of his latest, updated and most complete 356 book to the Registry.

Registry Chassis Number History

This database holds data from many sources, some editable by members and some only by administrators. It replaces the Members Car feature and the VIN Database from the legacy website site. Members may store their car along with photos and the club admins will store historical records.

This data should not be used to value any car; it is not guaranteed to be accurate.

Eric Cherneff's Serial Number Reference Site

Eric has been a contributor along with Bill Block and others to the Registry's database and has also created a site of his own.  It does not have information that has been collected on the Registry website. This site shows the range of the related chassis and engine numbers where one of the two is known.


Note that it doesn't look up matching engine and chassis numbers.  That is a paid service from various sources which are described elsewhere.

Elevenparts Original Engine Lookup Service

Elevenparts, a vendor in Switzerland, offers a free service on their website where you supply photos and they will tell you your original engine number. 

Note that you will not receive any documents when you use this site, just a return email with the numbers requested.







The Controversial Subject of "Matching Numbers"

This section contains links to information and the opinions of members to help the reader better understand the topic. All opinions are those of the authors and not of the Porsche 356 Registry.

Documents that Show Original Numbers

There are two documents that physically document the original matching numbers of a Porsche 356.  The Kardex is the factory warranty card which contains the original engine, transmission and chassis numbers of a 356 as well as the factory accessories that came with it. 
 
Porsche AG sells a Porsche Classic Technical Certificate which superseded the old Certificate of Authenticity. 

The following are links in which the alternative methods of documenting original numbers are discussed.

Sources for Obtaining Original Numbers

Kardex records are the property of Porsche; they are not available through Porsche or the Porsche 356 Registry. You may be able to acquire a Kardex via a third-party source if you ask other members or search the internet. 

The following is a link to information on the Porsche AG website about the Porsche Classic Technical Certificate.

Porsche 356 Registry Position Statement Against Counterfeiting and Fraud
The original Porsche sports cars were produced from 1948 through 1965 and have exceeded the factory’s and owners’ expectations for their longevity. The market value of the 356 series has continued to increase over the years with it now exceeding the value of many new 911 variants. This has resulted in an increasing number of 356s undergoing a thorough restoration – a trend supported by aftermarket reproduction of increasingly accurate components. 

Although 356s restored to original specifications are beloved by owners, some restorations take liberties with the objectives of this process...

These exceptions in one way or another are misrepresented by using key pieces of another 356 to indicate that the “restored” vehicle is something that it is not. This dishonesty may involve stamping chassis number plates or even a new bulkhead piece with another car’s number, or cutting the main bulkhead chassis stamping out of one car and welding it onto the “new” car. These transgressions include stamping engine serial numbers on to substitute timing case covers to “recreate” a matching-number engine or re-stamping other numbered components. Some of these “restorations” take the opportunity to recreate a higher valued model such as a Convertible D, Speedster, or Carrera from an otherwise ordinary model. These are not clearly identified tribute cars or outlaws, but attempts to misrepresent a car as having been produced as a special model by the factory.


We admire the commitment of owners who have the time and resources to restore their 356 Models to original factory specifications and condition. However, going beyond an honest objective by surreptitiously attempting to recreate a car that was not produced by the factory and thereby mislead future buyers in the interest of creating illegitimate value and profit is not merely deceitful, it is simply fraud.


It is the position of the international Porsche 356 Registry that any restoration of a 356 should generate complete and truthful documentation of the facts and processes of the restoration and that this documentation should faithfully follow changes in a car’s ownership. Individuals interested in buying a restored car – particularly special or high value models – should demand such documentation as a condition of purchase.


Any Porsche 356 that is used and enjoyed as the factory intended requires at least diligent maintenance and perhaps even a full restoration at some point. For those cars that in the judgment of their owners have gone well beyond mere patina, the international Porsche 356 Registry encourages restoration that can then represent the specifications and condition the factory originally produced. However, it is important to the Porsche 356 community that current and future owners can be confident about what their car represents. We also charge restoration work to faithfully disclose the authenticity of the vehicle and major components with honest documentation.
