License Plate Lookup

Enter a 2-letter U.S. or Canadian state code and a license plate number to retrieve roadside-inspection records, VIN history, and registered carriers associated with that plate.

Find a plate

The lookup matches FMCSA roadside inspection records (the inspection vehicle's license_state + license_number), so coverage depends on whether a plate has been inspected on a federal commercial-vehicle inspection.

What you get

  • Roadside-inspection history — every Level I-VI inspection where the plate was scanned, with date, state, OOS flags, violation count, and a link to the full inspection detail.
  • VIN history — distinct VINs that have appeared on this plate (typical when a plate is reissued to a new vehicle).
  • Registered carriers — USDOT numbers that have operated under this plate, ranked by inspection count.
