What Vehicles Need a VIN Verification in California

Cars, pickups, semis, box trucks, trailers, motorhomes, motorcycles, OHVs — one licensed inspection covers every one of them. There is no separate “truck” or “motorcycle” service. What changes by class is which numbers and labels get recorded, and whether your vehicle is exempt from the REG 31 altogether.

Vehicle Verification, VIN Verification — Same Inspection

This trips up a lot of people and it is worth two minutes. The DMV and the street use different words for the same thing. If you were told to get either one, you are in the right place and you need the same appointment.

What the DMV calls it

  • Verification of Vehicle — the title printed on form REG 31 itself
  • Vehicle verification — the wording used throughout the DMV’s Vehicle Industry Registration Procedures Manual
  • Licensed Vehicle Verifier — the occupational licence the State issues

What everyone else calls it

  • VIN verification — by far the most common term in the trade and in search
  • VIN inspection or VIN check
  • Getting your REG 31 done

The practical version: you will never see the phrase “VIN verification” on a DMV form, a DMV web page, or the REG 31. That does not mean you asked for the wrong thing. A licensed vehicle verifier performing a vehicle verification, and a mobile VIN verification service completing your REG 31, are the same person doing the same job — this one.

How the DMV Classifies Your Vehicle

Registration class is a legal definition, not a judgement about how you drive. The definitions below come straight from the DMV’s Vehicle Industry Registration Procedures Manual — the same manual a verifier works from.

Motor truck
A vehicle designed, used or maintained primarily to transport property. VIRPM 13.010
Pickup
A motor truck with two axles and an unladen weight under 8,001 lbs (or a GVWR of 11,499 lbs or less), with an open box-type bed under 9 feet. Vehicles with utility beds are explicitly excluded. VIRPM 13.010
Truck tractor
Designed primarily to pull other vehicles rather than carry a load itself. VIRPM 13.010
Camp trailer
Designed for human habitation, under 16 feet long and 96 inches wide — tent trailers included. VIRPM 14.005
Utility trailer
Used for livestock or personal property, GVWR under 10,000 lbs. VIRPM 14.005

The one that surprises everybody

Your pickup is a commercial vehicle

Most people think of a half-ton pickup as a passenger vehicle — for a lot of households it is the family car. The DMV does not see it that way, and you can read the answer straight off the REG 31. The body type model table on the back of the form has separate columns for AUTOMOBILE and COMMERCIAL, and this is where the pickup lands:

REG 31 · Commercial column
  • PK — Pickup
  • PC — Pickup Club Cab
  • 3C / 4C — Ext. Cab Pickup
REG 31 · Automobile column
  • PM — Pickup w/Camper Mounted
  • VC — Van Camper
  • MH — Motorized Home

A plain pickup is a commercial body type. Mount a camper on it and it becomes BTM “PM”, an automobile. The form’s own instructions set the bar, and they are stricter than most owners expect:

Pickups-Mounted (CVC §§243, 362, 661) — To have BTM “PM”, the pickup must have a permanently attached camper shell, canopy, or similar mounted structure, and provide facilities for human habitation or camping purposes.

Advise owner that removal of the structure will require commercial registration and weight fees to be due.

California DMV form REG 31, Body Type Model codes — Important Notes

Two things worth pulling out of that. A shell alone is not enough — it has to be permanently attached and provide facilities for human habitation or camping. And the last sentence is a warning the DMV asks verifiers to pass on: take the camper off and commercial registration and weight fees come back due. It is not a one-way trip.

And five that are pickups even though they don’t look it

The same notes column names the multi-designed vehicles the DMV classifies as pickups (CCR §150.04): Cadillac Escalade EXT, Chevrolet Avalanche, Ford Explorer Sport Trac, Hummer H2 SUT and the Nissan Frontier. If you own one, expect the commercial column even though it reads as an SUV on the driveway.

The same logic runs through the van-camper conversion, which we have written up end to end: converting a commercial van to a Van Camper. Either way the body type model change needs a REG 31 completed after the alteration, so call before you file — the BTM on your title decides which forms apply.

We verify

What gets recorded

  • The public VIN — on 1970 and newer, usually the driver-side dash
  • Federal Certification Safety Label
  • Emissions label and odometer reading
  • Engine number — motorcycles only; make sure it is accessible

Heads up on motorcycles: a motorcycle with an engine change — or one last registered in California that no longer appears in the DMV database — must be inspected by the DMV or CHP rather than a licensed verifier. See the full restricted list →
