VIN & chassis lookup

A vehicle's sales name and model year may cover more than one engine or drivetrain. The exact code helps avoid applying another variant's oil, tyres, battery or replacement-part specification.

1. Check the vehicle identification plate or label. Depending on the manufacturer, it may show a model or chassis code (for example, NHP10 or RU3). The plate location varies by vehicle; consult the owner's manual rather than assuming one location.
2. Check registration or import documents. Japanese-market vehicles commonly use a chassis/frame reference such as NHP10-1234567; the prefix is the useful model code, but the number alone does not prove a specific trim or fitted part.
3. Search the verified code here. Enter the model-code prefix or a conventional 17-character VIN above, then open the matching CarFactBook dossier. Always check market, year range and source caveats before repairs.

A standard 17-character VIN can be decoded using NHTSA vPIC, but many Japanese domestic frame numbers are not standard VINs. CarFactBook does not claim a complete worldwide VIN-to-chassis mapping.

For example, browse the Toyota Aqua NHP10 exact-code reference and follow its documented specifications.
