Mercedes-Benz VIN Check
Every Mercedes-Benz vehicle manufactured for the North American market since 1981 carries a standardized 17-character Vehicle Identification Number (VIN) regulated by NHTSA under FMVSS 565 and ISO 3779. This code is unique to each vehicle and encodes the country of assembly, manufacturer identity, model attributes, engine configuration, model year, assembly plant, and production sequence number. Decoding a Mercedes-Benz VIN helps you verify a used-vehicle listing, confirm the correct parts and service history, check for open recalls, and detect potential title fraud.
Mercedes-Benz uses manufacturer-specific encoding in the Vehicle Descriptor Section (positions 4–8). Position 4 typically identifies the model line — for example, popular Mercedes-Benz models include C-Class, E-Class, S-Class, GLC, GLE, GLS, G-Class, EQE, EQS. Position 8 usually encodes the engine type. Position 9 is a mathematical check digit that detects typos and many forms of VIN tampering. Position 10 encodes the model year, and position 11 identifies the assembly plant. WDB/WDC/WDD indicate Germany-built Mercedes; 4JG indicates the Tuscaloosa, Alabama SUV plant.
Mercedes-Benz invented the automobile in 1886 and remains a benchmark for luxury and safety innovation. The Tuscaloosa plant produces GLE and GLS SUVs for the global market.
How to Read a Mercedes-Benz VIN
To read a Mercedes-Benz VIN manually, start with the WMI (positions 1–3) to confirm the manufacturer and country of origin. For Mercedes-Benz, the WMI prefixes in our database include WDB, WDC, WDD, 4JG and others depending on where the vehicle was built.
Position 4 encodes the Class. Common values include A=A-Class, B=B-Class, C=C-Class, D=CLA, E=CLS, F=SLK / SLC. Position 5 encodes trim or series level. Position 8 encodes the engine (A=1.3L Turbo, B=2.0L Turbo, C=3.0L I6, D=4.0L V8 Biturbo, E=6.0L V12). Position 9 is the check digit — our decoder validates it automatically using the ISO 3779 weighted-sum algorithm. Position 10 is the model year (see our year-code reference), and position 11 is the assembly plant (A=Sindelfingen, Germany, B=Bremen, Germany, C=Rastatt, Germany, D=Düsseldorf, Germany, E=East London, South Africa). Positions 12–17 are the unique serial number for that vehicle.
Because Mercedes-Benz may change VDS encoding between model years, treat decoded attributes as informational. Always confirm critical details (engine, trim, drivetrain) against the window sticker, build sheet, or dealer records.

| 7 | VDS | Restraint / body | Supplemental restraint or body attribute |
| 8 | VDS | Engine | A=1.3L Turbo; B=2.0L Turbo; C=3.0L I6; D=4.0L V8 Biturbo; E=6.0L V12; F=2.1L Diesel |
| 9 | Check digit | Validation | ISO 3779 weighted-sum check — detects typos and tampering |
| 10 | VIS | Model year | Standard 30-year letter/digit cycle (1980–2039) |
| 11 | VIS | Assembly plant | A=Sindelfingen, Germany; B=Bremen, Germany; C=Rastatt, Germany; D=Düsseldorf, Germany; E=East London, South Africa; F=Tuscaloosa, AL |
| 12–17 | VIS | Serial number | Unique production sequence at the assembly plant |
Frequently Asked Questions — Mercedes-Benz VIN
Where is the VIN on a Mercedes-Benz?
Driver's side dashboard, door jamb label, and on the service booklet.
What does WDB mean in a Mercedes-Benz VIN?
The WMI prefix WDB identifies a Mercedes-Benz vehicle. WDB/WDC/WDD indicate Germany-built Mercedes; 4JG indicates the Tuscaloosa, Alabama SUV plant.
How do I decode a Mercedes-Benz VIN for free?
Enter your 17-character Mercedes-Benz VIN in the decoder above. Our engine validates the check digit, reads the model year, identifies the assembly plant, and applies Mercedes-Benz-specific rules for positions 4–8 where available.
Can a Mercedes-Benz VIN tell me the engine type?
For most Mercedes-Benz models, position 8 encodes the engine family or displacement. Our decoder maps this using manufacturer data. Popular models like C-Class and E-Class are supported.
What plants build Mercedes-Benz vehicles?
Position 11 is the assembly plant code. Mercedes-Benz operates factories worldwide — our decoder translates the plant letter to a city and country. WDB/WDC/WDD indicate Germany-built Mercedes; 4JG indicates the Tuscaloosa, Alabama SUV plant.
How do I verify a Mercedes-Benz VIN is genuine?
Use our decoder to validate the check digit at position 9. A valid Mercedes-Benz VIN like WDDGF4HB0CA123456 must pass the ISO 3779 check-digit test. Also compare the dashboard VIN with the door jamb label — mismatches may indicate tampering.
Does the model year in a Mercedes-Benz VIN match the calendar year?
Not always. Position 10 encodes the model year using the standard 30-year ISO cycle. A vehicle assembled in late 2024 may carry a 2025 model-year code. Always treat position 10 as the manufacturer's designated model year.
Which Mercedes-Benz models can I decode?
Our decoder supports all Mercedes-Benz models with standard 17-character VINs since 1981, including C-Class, E-Class, S-Class, GLC, GLE, GLS, G-Class, EQE, EQS. WMI lookup works for every Mercedes-Benz VIN; detailed trim and engine data is available where manufacturer encoding is documented.
