Chassis Numbers

The chassis number for an Austin Countryman or Morris Mini Traveller is stamped onto a metal plate which is screwed onto the car, usually on the radiator cowl (between the radiator and the inner wing).


From 1960 to 1965 there were separate chassis plates for Austin and Morris, which looked like this:

In 1965 the engine number field was removed and a seatbelt anchorage compliance statement was added:

In 1968 the separate Austin and Morris chassis plates were replaced by a generic BMC design:


The general format for 1960 to 1969 UK built Mini Traveller and Countryman chassis numbers is:
M-AW4 -#####A

The chassis number is made up of the following components:

First position ("M" in the above example)
A = Austin
M = Morris

Second position ("A" in the above example)
A = the A series engine
The standard Mini engine for the period - 848cc for Mk1 and 998cc for Mk2

Third position ("W" the above example
W = Estate (with or without wood)

Fourth position ("4" in the above example)
4 = Mk1 Morris
6 = Mk2 Morris
7 = Mk1 Austin
B = Mk2 Austin

Fifth position - not always used (blank in the above example)
D = Deluxe
S = Super deluxe
L = Left hand drive
Right hand drive was not designated

Number positions ("#####" in the above example)
The sequential build number
The first estates have a sequence of 5 digits, by 1969 7 digits were being used

Last position ("A" in the above example)
A = Longbridge
This position was not always designated and all UK built estates were made in Longbridge anyway!

The chassis number is not to be confused with the Commission Number, which is stamped onto a red metal plate riveted onto the inner wing of later estates:
