VIN lookup

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.

Exactly 17 characters. Letters I, O, and Q are not permitted.

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.

Decode evidence & sources

Deterministic structure

These fields come directly from VIN positions and the published checksum calculation, with zero store IO.

World manufacturer identifier
1M1

Deterministic · VIN positions 1–3.

Vehicle descriptor section
AN07Y

Deterministic · VIN positions 4–8.

Check digit
1 · valid

Deterministic · position 9; calculated value 1.

Model year candidates
1987 or 2017

Position 10 repeats every 30 years; both candidates are retained and neither is silently selected.

North American serial sequence
026516

Deterministic · positions 12–17 for a North American WMI.

Sourced platform inference

The prefix store publishes only at support ≥ 3 and purity ≥ 90%. Prefix confidence is shown beside every established platform claim.

VIN-level rule claims

Rules published for individual VIN positions beyond the prefix — applied with the WMI, prefix, and model-year guards each rule was validated under. Year-scoped rules were checked against model year 2017, established by the federal observation agreeing with a position-10 candidate.

Temporarily unavailable

The VIN-level rule resolver did not return a reliable response

Deterministic validation and the prefix-level results above are unaffected. An outage here is not evidence that no VIN-level rule applies.

Not established

  • model line
  • generation
  • cab type

These are withheld claims, not negative findings.
