Decode the VIN. Inspect the evidence.
This truck and trailer VIN decoder validates all 17 positions, preserves model-year ambiguity, and resolves a vehicle platform only when VIN-prefix evidence clears the published support and purity floor.
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.

Normalized VIN: 1UYVS25376M818519
Deterministic structure
These fields come directly from VIN positions and the published checksum calculation, with zero store IO.
Position 10 repeats every 30 years; both candidates are retained and neither is silently selected.
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. Model-year-scoped rules stay suppressed here because position 10 alone cannot establish the year.
