Last updated: June 2026 · Data sources: NHTSA vPIC (live) and FMCSA public inspection records (periodic refresh).
Quick answer
The prefix 1HS is a International World Manufacturer Identifier (WMI) — the first three VIN characters that identify the manufacturer. It does not identify a specific truck or its history. Enter the full 17-character VIN to decode the exact vehicle and check its FMCSA DOT roadside inspection history.

Why a prefix isn't enough
The WMI (1HS) only tells you the manufacturer. The remaining 14 characters encode the model, engine, GVWR, plant, model year, and serial number — and the full VIN is what FMCSA roadside records are matched against. For a International VIN lookup, use the complete 17-character VIN.
