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.
