Identification numbers

Back to the History of the Coupés and Convertibles

	220SEb	300SE	250SE	280SE	280SE 3.5
Coupé	111.021	112.021	111.021	111.024	111.026
Convertible	111.023	112.023	111.023	111.025	111.027

From the 1960s onwards the build up of the identification code is as follows:
The numbers have 14 digits on all models.
* The first three digits: type (as W number).
* Next three digits: body type.
* A. Seventh digit: 1 for Left hand Driven cars built in Germany, if built outside Germany this number would be a 5.
* B. Seventh digit: 2 for Right Hand Driven cars built in Germany, if built outside Germany this number would be a 6.
* Eight digit: 0 for standard transmission, 2 for automatic transmission.
* Last six digits: serial number.

For example: 112.023-12-123456 would be the identification code for a 300SE Convertible (W112.023), Left Hand Drive built in Germany (1), Automatic transmission (2) and with 123456 as a serial number.

The engine number:
The engine numbers are built up almost the same as the identification code.

The first six numbers identify the type of engine (see 10) Engine specifications).
The next two numbers have the same meaning as they have in the identification code.
The last six numbers are the serial number, different than the serial number of the identification code .

For example: 130.980-20-123456 would be the engine number for a 280SE (M130.980), Right Hand Drive built in Germany (2), manual transmission (0) and with 123456 as a serial number.
