What does the 17-digit VIN represent?

Vehicle Identification Number (VIN) consists of 17 digits and letters, divided into six main sections. Extended information: 1、Section 1: 3 codes represent the country of manufacture, manufacturer, and vehicle type, identified by numbers or letters (positions 1~3). 2、Section 2: 5 codes indicate vehicle characteristics, defined by manufacturers—refer to manuals for details (positions 4~8). 3、Section 3: Check digit, represented by a letter or number, determined by manufacturers (position 9). 4、Section 4: Model year code, using letters/numbers per international standards (position 10). 5、Section 5: Assembly plant and location code, assigned by manufacturers (position 11). 6、Section 6: Serial number, manufacturer-defined (positions 12~17).
The 17-digit combination of letters and numbers in the Vehicle Identification Number (VIN) acts like a car's ID number, with each position holding specific meanings. The first digit represents the country of production, for example, L stands for China and J for Japan. The second digit usually indicates the manufacturer, with different letters corresponding to different brands. The third digit denotes the vehicle type category, revealing whether it's a sedan, SUV, or truck. Digits 4 to 8 are the vehicle descriptor section, containing information like the engine model and body type. The 9th digit is a check digit used for anti-counterfeiting purposes. The 10th digit is particularly important as it indicates the production year; for instance, P represents 2023 and R stands for 2024. The 11th digit is the assembly plant code. The last 6 digits are the production sequence number, essentially the vehicle's birth number. Remembering these details makes it much easier to check maintenance records or purchase parts.
When repairing cars, I most often look at the 10th digit of the VIN. Last year while helping a customer replace a transmission, he couldn't remember the model year. I pointed to the VIN in the lower left corner of the windshield and said: 'See this R? It means it's a 2024 model.' Actually, digits 4-8 are more practical. Last time I encountered a BMW with oil consumption issues, it was through this segment that I confirmed it had an N20 engine, so I directly ordered the improved valve cover. Some customers worry about buying flood-damaged cars, so I teach them to compare the VIN on the B-pillar nameplate with the one stored in the ECU, because forgers usually can't alter all locations. These combinations of numbers and letters hold too many stories.
From my experience, ordinary car owners only need to remember three key parts: the 1st digit indicates the manufacturing country (L stands for domestically produced vehicles), the 10th digit shows the model year (check against the alphabet chart), and the last four digits represent the production sequence. For example, my car's ending number 0782 means it was the 782nd vehicle produced that day. Once, a neighbor bought a used car, and I noticed the 10th digit of its VIN was K (corresponding to 2019), but the seller claimed it was a 2020 model—clearly a mismatch. I recommend taking a photo of your VIN during maintenance. If you ever need to check parts or service records, entering this 17-digit code on auto parts websites is far more accurate than describing the car model.
