Decode evidence & sources

Deterministic structure

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

World manufacturer identifier
1XP

Deterministic · VIN positions 1–3.

Vehicle descriptor section
BD49X

Deterministic · VIN positions 4–8.

Check digit

North American serial sequence

Sourced platform inference

The prefix store publishes only at support ≥ 3 and purity ≥ 90%. Prefix confidence is shown beside every established platform claim.

Temporarily unavailable

The platform resolver did not return a reliable response

Deterministic validation above is complete. Platform fields are withheld because an outage is not evidence that the VIN has no known platform.
