| 5N1 | Nissan/Infiniti SUV, built in the USA |
How an Infiniti VIN breaks down
Infiniti is Nissan's luxury division, so its VINs follow Nissan's structure under the 17-character ISO 3779 standard. Positions 1–3 are the World Manufacturer Identifier — Japan-built Infiniti cars commonly open JNK or JN1. Positions 4–8 encode the model line, body and engine; position 9 is the check digit; position 10 the model year; position 11 the plant; and 12–17 the sequential build number.
The engine and trim live in positions 4–8, which is why two same-year Q50 or QX60 models can carry different descriptor characters depending on configuration.
Decode vs. history: what the VIN can and can't tell you
Decoding an Infiniti VIN reveals the factory build — year, engine, plant and trim. It won't show post-sale events. For salvage, accident, flood and odometer brands, run the same VIN through a history report drawing on NMVTIS and state-DMV records.
