Decode evidence & sources

Deterministic structure

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

World manufacturer identifier
3C7

Deterministic · VIN positions 1–3.

Vehicle descriptor section
WRMBL

Deterministic · VIN positions 4–8.

Check digit
4 · valid

Deterministic · position 9; calculated value 4.

Model year candidates
1993 or 2023

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

North American serial sequence
639148

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 2023, established by the federal observation agreeing with a position-10 candidate.

Cab type
Regular Cab

Manufacturer-published position rule · WMI/prefix/year guards applied by the store.
