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.
01

Decoded identity

From the 17-character VIN via NHTSA vPIC

This VIN has not been decoded yet — the unit's carrier, inspection and plate history below is reconstructed from the FMCSA inspection feed regardless.

Decode evidence & sources

Deterministic structure

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

World manufacturer identifier
3AL

Deterministic · VIN positions 1–3.

Vehicle descriptor section
ACXFC

Deterministic · VIN positions 4–8.

Check digit
7 · valid

Deterministic · position 9; calculated value 7.

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
NT3121

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.

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.

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.

GVWR
Class 7: 26,001 - 33,000 lb (11,794 - 14,969 kg)

Observed directly for this VIN via NHTSA vPIC.

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.

Temporarily unavailable

The VIN-level rule resolver did not return a reliable response

Deterministic validation and the prefix-level results above are unaffected. An outage here is not evidence that no VIN-level rule applies.

Not established

  • platform resolution (temporarily unavailable)

These are withheld claims, not negative findings.
