Mercedes chassis codes are the quickest way to find parts that fit your car. Model names like E 320 or S 500 were used across several generations, but the chassis code, such as W124 or W222, points to one specific generation and body style. This guide explains what the letters mean, how to find the code for your car, and why it matters when you buy parts.
What a Mercedes chassis code means
A Mercedes-Benz chassis code is a letter followed by three digits. The three digits identify the model series, and the letter usually tells you the body style.
- W is the saloon, and it is also used for many SUVs and vans, such as the W463 G-Class and the W447 V-Class.
- C is the coupe, for example the C124 E-Class coupe and the C126 SEC.
- S is the estate, for example the S124.
- A is the cabriolet, for example the A124.
- R is the roadster, such as the R107 and R129 SL.
- X and V are used on some later models, such as the X290 AMG GT four-door and long-wheelbase S-Class versions.
Cars with the same three digits often share engines, gearboxes and many mechanical parts. Body panels, glass and trim are usually specific to one body style, so a C124 bumper will not always match a W124 saloon.
How to find your chassis code
- Your VIN. In most Mercedes-Benz VINs, the three digits after the first three characters are the model series. For example, a VIN starting WDB124 belongs to the 124 series.
- The vehicle data card. The data card lists the model and its options. Many owners keep it with the service book.
- The registration documents. These often show the model type or code.

Why the chassis code matters when you buy parts
Most parts are listed by chassis code because it is the most reliable way to match fitment. Three things are worth checking alongside it:
- Facelifts. Many generations changed bumpers, lights and interiors partway through production, so early and late cars can need different parts.
- Engine code. Engines and gearboxes depend on the engine code, not only the chassis. Our diesel engines guide explains the main OM60x codes.
- Market and drive side. European, US and right-hand-drive cars can differ in lighting, dashboards and exhausts.
