VIN Verification (REG 31) Not Always Required
Two specific situations where the DMV waives the vehicle verification step entirely. If your vehicle qualifies — you don't need a verifier. Or anyone.
These exceptions come from DMV registration manual §12.165. They apply to a narrow set of new vehicles purchased out of state. If your situation doesn't match either case exactly — all conditions, not just some — the REG 31 is still required. Not sure? Ask us before you assume. If you do need a VIN verification, see our full Miscellaneous Originals guide.
New Trailer — Out of State
For trailers entering the California PTI (Permanent Trailer Identification) program for the first time.
A new trailer purchased in another state and eligible for the Permanent Trailer Identification program is exempt from the REG 31 — provided all three of the following are true:
No prior registration of any kind, anywhere.
Must be factory-original as manufactured. Alterations or kit builds void the exception.
The Manufacturer's Certificate or Statement of Origin must be presented and secured — not a copy, not a dealer printout.
If all three conditions are met, no REG 31 is required. Proceed with your title application using the MCO/MSO and applicable registration forms.
New Commercial Vehicle — Out of State
Applies to heavy new commercial vehicles purchased out of state — complete units and multi-stage builds (cab + body).
A new commercial vehicle purchased in another state — whether as a complete vehicle or as an incomplete vehicle to which a new body was added — is exempt from the REG 31 provided all five conditions are met:
Exception: IRP registration issued within the last 60 days only is permitted.
Factory original. Adding a new body to an incomplete chassis (multi-stage build) is allowed — aftermarket modifications are not.
This exception is for heavy commercial vehicles only. Vehicles under that threshold still require a REG 31.
If it doesn't — the REG 31 is required, no exceptions.
Either a single MCO/MSO for the complete vehicle, or separate MCO/MSO documents for the cab/chassis and body — plus a REG 256 certifying "new components only" for the multi-stage build.
Emissions failure = REG 31 required. If the vehicle does not meet California emission standards, this exception does not apply — full stop. A REG 31 vehicle verification will be required regardless of all other conditions being met.
REG 256 — Emissions Certification Required
The owner must also submit a REG 256 (Statement of Facts) certifying both of the following:
- No alterations or modifications were made to the emissions system.
- The vehicle has a properly affixed label indicating it meets California/US emission standards — or the MCO/MSO states this directly.
Pro Tip — Body Type Model (BTM) Abbreviation
If the MCO/MSO doesn't include a recognized Body Type Model abbreviation (for example, P120SV for a step van), you can clarify it with a REG 256. A REG 31 is not required just to supply or correct the BTM — the REG 256 alone handles it.
