Common questions
Can you do the VIN verification for my out-of-state vehicle?
Yes, for most vehicles. Bring the vehicle and its title or registration from the other state, and we complete the Verification of Vehicle (REG 31) at our counter. Revived salvage, specially constructed, and a few other vehicles must be verified by the DMV or CHP instead.
I just moved to California. How long do I have to register my car?
20 days after becoming a resident or bringing the vehicle into the state. Most vehicles need a California smog certification and a vehicle verification (REG 31) first.
My car passed smog in another state. Do I still need a California smog check?
Usually, yes. The DMV requires a smog certification from a California station for most out-of-state vehicles: gasoline 1976 and newer, diesel 1998 and newer.
