The 10th digit 'M' in the VIN represents the year 2021. Below is relevant information about the VIN: VIN location: For trucks and large vehicles, it is generally located on the right side of the vehicle frame at the rear; for passenger cars, it is usually found in the lower left corner of the windshield (under the wiper deflector) or on the door frame below the passenger seat; for motorcycles, turn the handlebars fully to one side, and you'll find a nameplate below the odometer with the VIN; the vehicle's registration certificate also clearly states the VIN in the 'VIN' section. VIN content: The VIN, or Vehicle Identification Number, is like a vehicle's ID card—just as every person has their own identity card, each vehicle has a unique VIN composed of 17 digits or letters. People can learn a lot about a vehicle from its VIN, such as its place of manufacture, vehicle type, model year, assembly details, etc. Digits 1-3 represent the manufacturing location, brand, and type; digits 4-8 indicate vehicle characteristics; digits 9-11 denote the check digit, model year, and assembly plant; digits 12-17 represent the serial number, which is the last 6 digits of the VIN.

I've previously studied the Vehicle Identification Number (VIN) system. The 10th digit of the VIN represents the manufacturing year. The letter 'M' typically stands for 2021, but if your car is an older model, it could also refer to 1991, as the year codes cycle approximately every 30 years. A complete VIN consists of 17 digits and letters, with the first three indicating the manufacturer's location, the middle section detailing the vehicle model, and the last part being the serial number. For 2021 model year vehicles, 'M' is commonly used as the standard code—for example, 2020 is 'L', 2021 is 'M', and 2022 is 'N'. To accurately determine the year, I recommend not relying solely on this single digit but instead checking the vehicle's registration certificate or entering the full VIN into an online decoder website. The system is designed to uniformly identify a vehicle's production date, helping to avoid fraud when buying or selling used cars. Remember, the year code assists in matching the correct parts during vehicle maintenance, improving service efficiency.

I often check the VIN to confirm vehicle information. If the 10th digit is M, it's usually a new car manufactured in 2021. In the standard VIN year code system, 2010=A, 2011=B, and 2021=M, with letters used consecutively in alphabetical order. If M appears on an older model, it might indicate a 1991 vehicle. The VIN is typically found under the windshield or on the door edge, and the full 17-digit code reveals the year, origin, and production sequence. When checking, I remind everyone not only to focus on the year letter but also to verify the entire VIN against registration documents to prevent tampering or errors. New cars commonly use the M code, but the used car market might confuse the year, leading to unreasonable pricing. For safety, use a mobile app or website to quickly decode the full VIN details, ensuring accurate vehicle records.

The 10th character in a VIN represents the model year, with 'M' corresponding to vehicles manufactured in 2021. The standard coding system assigned 'M' for 2021, but since it repeats every 30 years, the same letter was also used in 1991. The vehicle year code helps identify production time—for example, many new cars launched in 2021 carried the 'M' designation. A VIN is 17 characters long, with the first section indicating manufacturer details, while the year digit is centrally located for easy verification. It's helpful to remember this letter sequence: 2020=L, 2021=M, 2022=N, making it easier to manually check the windshield label. For older vehicles, 'M' might indicate 1991, requiring assessment based on appearance or records to avoid mismatched repair parts.
