Isuzu VIN Check
Isuzu commercial trucks sold in North America use ISO 3779 VINs with WMI JAL for Japan-built incomplete chassis-cabs. Positions 4–8 encode GVWR class, series (NPR/NQR/NRR/FTR), cab type, drive, and engine. Position 12 distinguishes close siblings such as NQR vs NRR.
Our decoder maps those codes from Isuzu's Part 565 manufacturer identification document, including the Fujisawa plant code and 4HK1-TC diesel engine family used on modern N-Series trucks.
How to Read a Isuzu VIN
Start with the WMI (positions 1–3): JAL = Isuzu Japan incomplete medium/heavy. Position 5 sets the series (4 NPR, 5 NQR/NRR, 6 FTR/FVR). Position 8 6 is the 5.2L 4HK1-TC diesel. Position 11 7 is Fujisawa. Position 12 3 identifies NRR; 9 identifies NQR.
