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.
Decode result
Normalized VIN: 1NKDLU0X83J704165
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.
No supported platform claim is established for this prefix
The resolver answered successfully but returned no row above the evidence floor. This does not mean the vehicle has no platform or that no data exists; it means this store cannot make the claim.
Not established
- platform make
- platform model
- model line
- generation
- cab type
These are withheld claims, not negative findings.
