Look up any truck or trailer VIN.
Carrier history, roadside inspections, and an evidence-based platform decode — from the federal record and manufacturer VIN tables.
Evidence and legal guardrail
Decoded platform claims are inferences, and every published claim retains its source and confidence. Derived from manufacturer coding tables and our own decoded corpus; not an official government decode.
“Not established” means the available evidence did not establish the field. It never means the vehicle has no such attribute or that no data exists elsewhere.
What the result separates
Deterministic VIN structure stays distinct from corpus and manufacturer-sourced platform inferences.
Structure & checksum
WMI, VDS, ISO 3779 transliteration, position weights, and an exact position-9 check-digit verdict.
Model year candidates
Position 10 repeats every 30 years. Both candidates stay visible instead of silently choosing one.
Platform resolution
Make, model, model line, generation, and cab type publish only at support ≥ 3 and purity ≥ 90%.
What we decode
Manufacturer-specific evidence defines the capability. Reused or absent codes are a refusal, not an invitation to infer.
| Make or boundary | Published behavior | Evidence class |
|---|---|---|
| Freightliner | Cascadia 113″, 116″, 125″ and 126″ lines with sleeper/day-cab splits; M2 106/112, Columbia, Coronado and Classic lines. | Manufacturer coding table · Daimler |
| Western Star | 5700XE cab split when the manufacturer code and evidence floor both establish it. | Manufacturer coding table |
| Kenworth | T600, T800 and W900 series claims where the filed VIN code is specific enough to publish. | Regulatory filing |
| Peterbilt / Kenworth refusal | Peterbilt 579 and Kenworth T680 codes reuse across decades; we refuse rather than mislabel. | Regulatory filing |
| International | LT, ProStar, MV, DuraStar, RH, HV, LoneStar and HX lines under the Navistar VIN filing. | Regulatory filing · 49 CFR Part 565 |
| Trailers | Great Dane Freedom line; Hyundai Translead dry-van or reefer for model year 2022 and newer. Utility’s own bulletin confirms reefer versus dry van is not encoded in the VIN, so we do not guess it. | Manufacturer coding table / bulletin |
| RAM | 4500 and 5500 cab claims where the filed manufacturer code establishes the cab configuration. | Regulatory filing |
| Volvo refusal | Volvo VNL has no VIN position that separates the generations; we say “Not established” rather than guess. | Manufacturer coding table |
VIN decoder FAQ
The answers below are the same claims published in the page’s structured data.
Can this truck VIN decoder identify a sleeper or day cab?
Only when a manufacturer-specific coding table or regulatory filing establishes the cab code and the stored prefix clears support ≥ 3 and purity ≥ 90%. Otherwise, we show “Not established.”
Why does a VIN not resolve?
The VIN may fail its 17-character or check-digit validation, its prefix may not clear the published evidence floor, or the platform resolver may be temporarily unavailable. Those states are shown separately.
Is this an official government VIN decode?
No. It combines deterministic VIN structure with Vektor corpus evidence and manufacturer or regulatory sources. It is not an official government decode.
Do you store my VIN?
Submitting the form does not write the VIN to Vektor’s platform store. The VIN becomes part of the page URL, so it can remain in browser history and normal request logs.
What makes this decoder different?
Every published platform claim retains its source, corpus support, and prefix purity. Ambiguous or unsupported fields remain “Not established” instead of being guessed.
