Mercedes-Benz VIN Decoder & Check
Decode any Mercedes-Benz VIN free, then read the full vehicle history before you buy.
Buying a used Mercedes-Benz?
Mercedes-Benz traces to Karl Benz's 1886 Patent-Motorwagen, the first practical automobile. The modern range runs from the CLA to the S-Class and the electric EQ line, and since 1997 the GLE and GLS SUVs have been built in Tuscaloosa, Alabama, making 4JG one of the most common prefixes on American-market Mercedes SUVs.
Used Mercedes prices follow a cliff: gently for the first owner, steeply after. The result is a market full of impressive cars whose next repair bill exceeds their monthly payment ever was, plus the rebuilt and flood-damaged examples that steep depreciation always attracts. A branded title cuts a Mercedes' value harder than almost any mainstream car, which makes title verification the single highest-value check on the brand.
Mercedes-Benz history: what to verify before you buy
Every brand has its own used-market patterns. These are the ones worth checking on a Mercedes-Benz, and where the report answers each one.
Balance-shaft era V6 engines
The M272 V6 in many 2005 to 2008 models had balance-shaft gear wear that led to a class-action settlement. On cars from that window, mileage history and service cadence deserve attention before any purchase.
Airmatic suspension costs
Air suspension on E-Class, S-Class, and the SUVs rides beautifully and fails expensively with age. The factory maintenance schedule and odometer chronology in the report frame what a high-mile car is due for.
Takata inflator recalls
Mercedes recalled large numbers of vehicles for Takata inflators across the 2000s and 2010s. The recall section shows whether the campaign is closed on the specific VIN.
Branded-title value collapse
A salvage or rebuilt brand on a Mercedes erases a huge share of its value, so sellers work hardest here to obscure it. The report follows the title through every state and surfaces the salvage-auction listings, photos included.
How to decode a Mercedes-Benz VIN
Every Mercedes-Benz built since 1981 carries a 17-character VIN, and each position means something specific. Here is how to read one yourself, or paste it above and let the decoder do it in seconds.
Example VIN for illustration. Positions 1 to 3 identify the manufacturer, 4-8 describe the vehicle, 9 is the check digit, 10 is the model year, 11 is the assembly plant, and 12-17 are the serial number.
Positions 1-3: where your Mercedes-Benz was built
The first three characters are the World Manufacturer Identifier, assigned to a specific company, country, and vehicle type. This is the fastest answer to the question of which factory built the car.
| WMI code | Built in | Typically used on |
|---|---|---|
| W1K | Germany | Current German-built cars such as the C and E-Class |
| WDD | Germany | Recent German-built sedans and coupes |
| WDB | Germany | Older German-built Mercedes models |
| W1N | Germany | Current German-built SUVs such as the GLC |
| 4JG | Tuscaloosa, Alabama | US-built SUVs such as the GLE and GLS |
Common Mercedes-Benz manufacturer codes. Codes vary by model, plant, and era, so a code outside this table is not by itself a red flag. The free decoder above resolves any Mercedes-Benz VIN to its exact factory record.
Positions 4-8: what the vehicle is
Mercedes encodes the model series, body, engine, and restraint system in positions 4 through 8, which separates a C 300 from an AMG C 63 and a rear-drive car from a 4MATIC.
Position 9: the check digit
A number computed from all the other characters using a federal formula. If someone alters a VIN by hand, the math stops working. It is the first thing our decoder verifies, and a failed check digit on a listing is a walk-away signal.
Position 10: the model year
One character encodes the model year. Letters and digits alternate in a 30-year cycle, so the same code serves two eras:
Year codes repeat every 30 years. Position 7 settles the cycle: on 17-character VINs, a letter there means the vehicle is from 2010 or later, a digit means 1981-2009.
Positions 11-17: plant and serial number
Position 11 names the assembly plant within the factory network, and the final six characters are the serial number, unique to this one Mercedes-Benz. Together with the rest of the VIN, they make the identity impossible to share honestly, which is exactly why cloned VINs are worth checking for.
