REG 343 Form – If you’re registering a vehicle in California for the first time, bringing an out-of-state car into the state, or reregistering a revived junk or salvage vehicle, you’ll need the REG 343 form—officially called the Application for Title or Registration/Verification of Vehicle. This essential California DMV document ensures your vehicle gets properly titled and registered under state law.
In this complete guide, you’ll learn exactly what the REG 343 form is, who needs it, how to download the latest PDF, a step-by-step guide to filling it out accurately, required supporting documents, submission instructions, and answers to frequently asked questions. All information is based on current official California DMV resources.
What Is the REG 343 Form?
The REG 343 is the California DMV’s official two-sided application used to apply for a vehicle title and/or registration. It is required for:
- Vehicles being registered in California for the first time.
- Non-resident/out-of-state vehicles brought into California.
- Reregistering vehicles that have been junked, salvaged, or removed from DMV records.
You must submit the completed REG 343 with appropriate fees within 20 days of the date the vehicle is first operated in California (or the date you become a California resident, whichever applies first). The form collects critical details about the vehicle, owners, purchase information, odometer reading, and more. It must be signed under penalty of perjury.
Current revision: REG 343 (REV. 12/2022) – the version uploaded by the DMV in early 2025 matches the link you provided.
Who Needs to File the REG 343 Form?
You need to complete and submit the REG 343 if you:
- Purchase a new or used vehicle from a dealer or private party (when the dealer does not handle the paperwork).
- Bring a vehicle from out of state into California.
- Register a vehicle for the first time in California.
- Reregister a revived junk, salvage, or previously removed vehicle.
- Register specially constructed, modified, or commercial vehicles (additional forms may apply).
Dealers often handle this for in-state purchases, but private sales, out-of-state moves, and special circumstances require you to file it yourself.
