Freightliner 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 14 codes below are the ones verified for Freightliner in vPIC: 3AK, 1FU, 3AL, 1FV, 4UZ, 2FV, 2FU, 3BH, 3BJ, 3FF, AFV, KFB, RSA and RSB. The list is built from the manufacturers the VINs sampled for this page decode to, and NHTSA can have issued Freightliner other codes for other plants and vehicle types. 6 of them appeared in the 150 Freightliner VINs sampled from FMCSA roadside inspection records for this page; the rest are registered with NHTSA but did not show up in that sample.

DAIMLER VEHÍCULOS COMERCIALES MÉXICO S. DE R.L. DE C.V. also files WESTERN STAR with NHTSA, in some cases under the codes above. DAIMLER TRUCK NORTH AMERICA LLC also files WESTERN STAR with NHTSA, in some cases under the codes above. FREIGHTLINER CUSTOM CHASSIS CORP. also files MITSUBISHI FUSO with NHTSA, in some cases under the codes above (see the Western Star 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 Freightliner: decode it to check.

3ALHHTDV3RSUZ0506 is a Freightliner truck recorded in a roadside inspection and decoded clean by vPIC. Reading it left to right:

• Positions 1 to 3, 3AL. The WMI. vPIC resolves it to DAIMLER VEHÍCULOS COMERCIALES MÉXICO S. DE R.L. DE C.V., filed for incomplete vehicles and assigned to Mexico.
• Positions 4 to 8, HHTDV. The vehicle descriptor, whose meaning Freightliner's manufacturer defines in its filing. For this VIN vPIC read model Cascadia, body class Truck, GVWR Class 8: 33,001 lb and above (14,969 kg and above) and engine DD13 from these five characters.
• Position 9, 3. 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, R. The model year code. vPIC decodes it as 2024. vPIC flags the code as ambiguous for this filing (year codes repeat every 30 years), so confirm against the certification label.
• Position 11, S. The assembly plant. vPIC names Saltillo, Coahuila, Mexico.
• Positions 12 to 17, UZ0506. The production serial. It identifies the unit and decodes to nothing on its own.

vPIC's own pattern for this unit is 3ALHHTDV*RS: the positions it decoded from, with the check digit masked. Two Freightliner 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:

• DAIMLER VEHÍCULOS COMERCIALES MÉXICO S. DE R.L. DE C.V. Registered with NHTSA in Cuajimalpa, Ciudad de México, Mexico as Completed Vehicle Manufacturer and Incomplete Vehicle Manufacturer. Registered vehicle types: Truck, Class 6: 19,501 - 26,000 lb (8,845 - 11,794 kg) to Class 8: 33,001 lb and above (14,969 kg and above); Incomplete Vehicle, Class 6: 19,501 - 26,000 lb (8,845 - 11,794 kg) to Class 8: 33,001 lb and above (14,969 kg and above). 92 of the sampled Freightliner VINs decoded to it.
• DAIMLER TRUCK NORTH AMERICA LLC. Registered with NHTSA in Portland, Oregon, United States as Completed Vehicle Manufacturer, Incomplete Vehicle Manufacturer and Importer of Motor Vehicles Originally Manufactured to Conform to FMVSS. Registered vehicle types: Truck, Class 5: 16,001 - 19,500 lb (7,258 - 8,845 kg) to Class 8: 33,001 lb and above (14,969 kg and above) (primary); Incomplete Vehicle, Class 6: 19,501 - 26,000 lb (8,845 - 11,794 kg) to Class 8: 33,001 lb and above (14,969 kg and above). 55 of the sampled Freightliner VINs decoded to it.
• FREIGHTLINER CUSTOM CHASSIS CORP. Registered with NHTSA in Gaffney, South Carolina, United States as Incomplete Vehicle Manufacturer. Registered vehicle types: Incomplete Vehicle, Class 2H: 9,001 - 10,000 lb (4,082 - 4,536 kg) to Class 8: 33,001 lb and above (14,969 kg and above) (primary). 2 of the sampled Freightliner VINs decoded to it.
• FREIGHTLINER CORPORATION. Registered with NHTSA in Portland, OR, United States. Its registration record carries no GVWR range. 1 of the sampled Freightliner VINs decoded to it.

Second, the GVWR class vPIC returned for each of the 150 Freightliner VINs in the sample (a class is filed on 148 of them; the rest carry no GVWR in the manufacturer's filing):

• Truck-Tractor: 101 units
• Truck: 46 units
• Incomplete - Chassis Cab (Single Cab): 1 unit
• Incomplete - Glider: 1 unit
• Step Van/Walk-in Van: 1 unit

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 Freightliner 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 1,283,765 truck tractor records under the code FRHT, 946,939 truck tractor records under the code FREIGHTLIN and 268,238 straight truck records under the code FRHT. Native Base pulled 150 distinct VINs from those codes and sent them to NHTSA vPIC in batches: 150 came back, 150 decoded as FREIGHTLINER, 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: 1994 to 2024.
• Plants vPIC named most: Saltillo, Coahuila, Mexico (71), Santiago, Mexico (38) and Cleveland, North Carolina, United States (26).
• Vehicle types vPIC lists under the FREIGHTLINER make: Truck, Bus, Multipurpose Passenger Vehicle (MPV) and Incomplete Vehicle.
• WMIs verified one by one through vPIC DecodeWMI; manufacturer registrations from GetManufacturerDetails. Fetched 2026-09-27.
