A unit that bounces between many operators can indicate slip-seating, heavy sub-haul, or double-brokering. Review the carrier timeline below for load integrity — context for human judgment, not a verdict.

Decode evidence & sources

Deterministic structure

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

World manufacturer identifier
1UY

Deterministic · VIN positions 1–3.

Vehicle descriptor section
FS254

Deterministic · VIN positions 4–8.

Check digit
5 · valid

Deterministic · position 9; calculated value 5.

Model year candidates
2004 or 2034

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

North American serial sequence
172201

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.

Not established

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.

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 2004, established by the federal observation agreeing with a position-10 candidate.
