Each of the 17 digits in Nissan VIN decoding has a specific value. The first three digits, which is the World Manufacturer Identifier, reveals the manufacturing country, manufacturer, and car type. For example, JN1 would be a Japan produced Nissan passenger vehicle.
The fourth digit to decode a Nissan VIN is the extended engine type, while the fifth digit is the extended model line (such as B for Sentra, C for Versa, or J for Maxima). The sixth digit is for the model change, while the seventh is for the body type (such as 4 for 2-door coupe and 5 for 4-door wagon) and the eight digit represents the restraint and drive trains.
The ninth digit, which is also called the “check” digit, can be from 0 – 9 or the letter X and is purposefully kept secret. Only the manufacturer and law enforcement can access this number to verify the authenticity of a VIN.
The tenth digit is for the model year, with L beginning in 1990 and proceeding consecutively through the alphabet before switching to numbers and then coming back to letters, reaching H for 2017. The eleventh digit is the manufacturing plant code, such as C for Tennessee, M for Rochigi, or T for Oppama.
Finally, the last six numbers are the car’s unique serial number based upon the manufacturing order, or the order in which the car came off the assembly line that year for the model.
