How Porsche 356 chassis numbers were allocated
The four 356 series and how many were built
Documented chassis ranges by body builder
How to confirm a 356 with the Kardex and the registry

Short answerPorsche 356 chassis numbers have five or six digits, allocated in blocks to body builders such as Reutter, Drauz and D’Ieteren. A number points to a series and body family, but bodies were not built in numerical order, so it cannot prove the exact year or body. About 76,000 356s were built from 1948 to 1965; the Kardex confirms each one.

Published registry ranges place this number. A Kardex copy confirms the exact car.

The 356 is the Porsche whose chassis number says the least on its own. The numbering was organised around the coachbuilders who made the bodies, not around the calendar, so a 356 number is a lead to follow rather than a verdict.

How were Porsche 356 chassis numbers allocated?

Porsche 356 chassis numbers were allocated in blocks to body types and body builders. Reutter built most steel coupés and cabriolets, Drauz and D’Ieteren built open cars, and each block of numbers went to a particular body family. The bodies were then delivered to Porsche and fitted to cars as they arrived, so neighbouring numbers were not necessarily built in order.

That is why a 356 chassis number can suggest a series and body style but cannot, by itself, prove the exact model year or specification.

What are the four Porsche 356 series?

The Porsche 356 was built in four series between 1948 and 1965.

Series	Years	Built	Notes
Pre-A	1948–1955	7,627	Includes the aluminium Gmünd cars and early Zuffenhausen production
356 A	1955–1959	21,045	T1 and T2 body revisions; Speedster and Convertible D
356 B	1959–1963	30,963	T5 body from late 1959, T6 from 1961–62; Roadster
356 C	1963–1965	16,678	Disc brakes; last 356s

The first cars were hand-built in aluminium at Gmünd, Austria, from 1948; the 356 Registry lists the Gmünd chassis as 001 to 057, built between 1949 and 1952. Production then moved to Zuffenhausen with steel bodies. The first car of all, 356 “No. 1”, was a mid-engined prototype.

Which 356 chassis ranges are documented?

Published registry research documents several ranges by body type. The table shows a selection with the counts reported for each block.

Chassis range	Body builder	Series and model year
85887–86830	Drauz, Convertible D	356 A T2, 1959
151532–152475	Reutter, cabriolet	356 A T2, 1959
152476–152943	Reutter	356 B T5, 1960 model year (468 cars)
152944–154560	Reutter	356 B T5, 1960 (1,617)
154561–155569	Reutter	356 B T5, 1961 model year (1,009)
155601–156999	Reutter	356 B T6, 1962 model year (1,399)
157000–158700	Reutter	356 B T6, 1963 model year (1,701)

Published summaries disagree on whether the Reutter 356 B blocks above are coupés or cabriolets, so treat the body style as unconfirmed until the factory record shows it.

Roadsters were also built in Belgium by D’Ieteren: 473 on the T5 body and 249 on the T6. Documented examples include T5 chassis 89155 and 89204 and T6 chassis 89750. The complete tables for every body family are maintained by the Porsche 356 Registry.

How do you confirm a Porsche 356 chassis number?

You confirm a Porsche 356 chassis number with the factory record and the registry, then the car itself.

Decode the number with the decoder above to confirm it is a 356-format number.
Compare it with the 356 Registry’s published ranges for the claimed body and series.
Order the factory record. For 356s the Kardex records chassis, engine and gearbox numbers, colours and options, as explained in the Porsche Certificate of Authenticity guide.
Check the stampings and body tags on the car against both, using where to find the VIN on a Porsche.

How is a 356 number different from a 911 number?

A 356 number is different from a 911 number because the 911 numbering started over. The first production 911 is chassis 300001, and from 1968 the 911’s number itself encodes year and variant. The formats are explained in the Porsche 911 VIN decoder.

Frequently asked questions

How many digits is a Porsche 356 chassis number?

Production 356 chassis numbers have five or six digits. The earliest hand-built Gmünd cars used low numbers, which the 356 Registry lists as chassis 001 to 057.

Does a 356 chassis number show the body builder?

It points to one. Porsche allocated number blocks to body types and coachbuilders, so a number in a builder’s block suggests the body, but only the factory record confirms it.

How many Porsche 356s were built?

About 76,000: 7,627 pre-A cars, 21,045 356 A, 30,963 356 B and 16,678 356 C, according to published production figures.

Can this decoder read every 356 number?

It recognises five- and six-digit 356 numbers and marks the series family as unknown until confirmed, because full 356 production tables are not public. Use the Kardex and the Porsche 356 Registry for a definitive answer.
