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.
Four Classes, One REG 31
The DMV groups vehicles by how they are registered, not by what they look like in your driveway. These are the four buckets that actually change what happens at your appointment.
Passenger Vehicles
Cars, SUVs, minivans, passenger vans, motorcycles, LSV & NEV. The everyday driveway appointment.
On this page ↓Commercial Vehicles
Tractor trucks, box vans, cranes, yard trucks — and, to the DMV’s way of thinking, your pickup.
See commercial →Trailers, RVs & OHVs
Travel and utility trailers, boat trailers, motorhomes, camper vans, ATVs and dirt bikes.

Revived salvage, revived junk and incomplete vehicles are restricted to the DMV and CHP by law.
Where to go instead →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. Under VIRPM 13.010 a pickup is a motor truck, and motor trucks are registered commercially and carry commercial weight fees, even when the vehicle never hauls anything heavier than groceries.
There is a documented way out. The DMV’s conversion from commercial to auto licence plates (VIRP 13.030) lets a vehicle altered for human habitation — a mounted camper, a converted cargo van — move to auto plates and drop the commercial weight fees. That conversion requires certification of the living quarters and a REG 31 completed after the alteration, which is where a verifier comes in.
We have written up the whole process for van builds: converting a commercial van to a Van Camper. The forms and the logic are the same idea for a pickup carrying a mounted camper — call us before you file anything, because the body type model on your title decides which forms apply.
Passenger Vehicles
The vehicles we verify every day — at a driveway, an office car park, or a dealership lot. The on-site paperwork usually takes under 15 minutes.
We verify
- Cars, sedans, SUVs and crossovers
- Minivans and passenger vans
- Pickups — see the classification note above; the inspection itself is identical either way
- Motorcycles — new, or last registered out of state
- Low-Speed Vehicles (LSV) and Neighborhood Electric Vehicles (NEV)
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 →
