Isuzu VIN decoder,
from the NHTSA record.

A World Manufacturer Identifier is the first three characters of the VIN. NHTSA assigns each one to a manufacturer, and vPIC records the vehicle type and country it was issued for. The 16 codes below are the ones verified for Isuzu in vPIC: JAL, 54D, 4GT, 4KL, 1GG, 4NU, 4S1, 4S2, 4VZ, J87, J8C, J8T, JAA, JAB, JAC and JAM. The list is built from the manufacturers the VINs sampled for this page decode to, and NHTSA can have issued Isuzu other codes for other plants and vehicle types. 4 of them appeared in the 149 Isuzu VINs sampled from FMCSA roadside inspection records for this page; the rest are registered with NHTSA but did not show up in that sample.

ISUZU MOTORS LIMITED, JAPAN also files ACURA, ASUNA, CHEVROLET, GEO, GMC and HINO with NHTSA, in some cases under the codes above. THE SHYFT GROUP, INC. also files CHEVROLET, GMC, SPARTAN MOTORS, SPARTAN MOTORS CHASSIS and SPARTAN RV CHASSIS with NHTSA, in some cases under the codes above. GENERAL MOTORS LLC also files ACURA, AMERICAN MOTORS, BRIGHTDROP, BUICK, CADILLAC, CHEVROLET and 13 more with NHTSA, in some cases under the codes above (see the Hino page). Where a code is filed for more than one make, the makes-filed column says so. A VIN that starts with a code not in this table can still be a Isuzu: decode it to check.

JALE5W165P7302655 is a Isuzu incomplete - chassis cab (single cab) recorded in a roadside inspection and decoded clean by vPIC. Reading it left to right:

• Positions 1 to 3, JAL. The WMI. vPIC resolves it to ISUZU MOTORS LIMITED, JAPAN, filed for incomplete vehicles and assigned to Japan.
• Positions 4 to 8, E5W16. The vehicle descriptor, whose meaning Isuzu's manufacturer defines in its filing. For this VIN vPIC read model NRR, series ISUZU NQR / NRR, body class Incomplete - Chassis Cab (Single Cab), GVWR Class 5: 16,001 - 19,500 lb (7,258 - 8,845 kg) and engine 4HK1-TC from these five characters.
• Position 9, 5. The check digit, computed from the other sixteen characters. vPIC reports this VIN with error code 0, so the digit calculates correctly and the VIN was read right.
• Position 10, P. The model year code. vPIC decodes it as 2023. vPIC flags the code as ambiguous for this filing (year codes repeat every 30 years), so confirm against the certification label.
• Position 11, 7. The assembly plant. vPIC names Fujisawa, Kanagawa Prefecture, Japan.
• Positions 12 to 17, 302655. The production serial. It identifies the unit and decodes to nothing on its own.

vPIC's own pattern for this unit is JALE5W16*P7: the positions it decoded from, with the check digit masked. Two Isuzu VINs that share that pattern share every attribute vPIC filed for it and differ only in the check digit and the serial.

Two reads of the gross vehicle weight rating, both from the federal record. First, what the manufacturer registered with NHTSA:

• ISUZU MOTORS LIMITED, JAPAN. Registered with NHTSA in Shinagawa-ku, Tokyo, Japan.

Second, the GVWR class vPIC returned for each of the 149 Isuzu VINs in the sample:

• Incomplete - Chassis Cab (Single Cab): 110 units
• Truck: 38 units

If the VIN is not to hand, the rating is on the certification label on the unit itself; how to find GVWR walks through where to look.

3 real Isuzu VINs from FMCSA's roadside inspection file, each decoded by vPIC with error code 0. Every field shown is what the manufacturer filed; a field that is missing was not filed for that pattern. Paste any of them into the decoder above to see the full card.

FMCSA's Inspections Per Unit file (data.transportation.gov, dataset wt8s-2hbx) records every vehicle in a roadside inspection with the make code the inspector typed. It holds 73,860 straight truck records under the code ISU and 56,615 straight truck records under the code ISUZU. Native Base pulled 150 distinct VINs from those codes and sent them to NHTSA vPIC in batches: 150 came back, 149 decoded as ISUZU, and 147 with a clean error code. The decode, not the inspector's code, decides what a unit is, which is why the same make appears under several spellings in the file.

• Model years in the sample: 1999 to 2024.
• Plants vPIC named most: Fujisawa, Japan (97), Charlotte, Michigan, United States (41) and Fujisawa, Kanagawa Prefecture, Japan (6).
• Vehicle types vPIC lists under the ISUZU make: Passenger Car, Truck, Multipurpose Passenger Vehicle (MPV) and Incomplete Vehicle.
• WMIs verified one by one through vPIC DecodeWMI; manufacturer registrations from GetManufacturerDetails. Fetched 2026-09-27.
