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
121

Deterministic · VIN positions 1–3.

Vehicle descriptor section
CP532

Deterministic · VIN positions 4–8.

Check digit
5 · valid

Deterministic · position 9; calculated value 5.

Model year candidates
1991 or 2021

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

North American serial sequence
018831

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.

Federal observation (NHTSA vPIC)

What the federal corpus observed directly for this exact VIN — independent of, and sometimes more specific than, the prefix-level inference above.
