What is REG 343?

Moving to California with an out-of-state car, buying a vehicle from outside California, or registering a vehicle that has no California Certificate of Title? Form REG 343 is the primary application for a California title and registration. Because the form states "COMPLETE BOTH SIDES" and packs 8 dense sections covering vehicle specs, fuel/motive power, registered owner, lienholder, and out-of-state tax credit calculations, JustFill lets you type every box cleanly in your browser — or batch-generate REG 343 packets from CSV if you are a dealer or fleet manager.

Who fills out REG 343?

  • New California residents registering a car, truck, motorcycle, or trailer previously titled in another state

  • Auto dealers, fleet managers, and DMV registration services preparing California title and registration packets

Field-by-field breakdown

What each section of REG 343 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Section 1 — Vehicle information

VIN, vehicle type, year, make, model, body type, license plate (if any), number of axles, unladen weight (for commercial vehicles), motive power/fuel type, and odometer reading.

Section 2 — Registered owner(s)

True full name (last, first, middle) or business name, California driver license or ID number for each owner, relationship connector (AND / OR), physical residence or business address, and mailing address.

Section 3 — Legal owner (lienholder)

Name and address of the bank, credit union, or finance company holding the lien (or write "None" if there is no loan), plus Electronic Lien and Title (ELT) number if applicable.

Sections 4 & 5 — Cost/value & out-of-state entry dates

Purchase date, purchase price or gift value, date the vehicle entered California, date it was first operated in California, and any sales tax paid to another state.

Sections 6 & 7 — Out-of-state registration & commercial/bus questions

Previous state of title/registration, whether the plates are being surrendered, and commercial weight or for-hire disclosures.

Section 8 — Certification & signatures

Signed and dated under penalty of perjury by each registered owner listed in Section 2.

Common mistakes to avoid

  • 1Completing only Page 1 — Form REG 343 explicitly warns "COMPLETE BOTH SIDES", and the out-of-state dates, cost details, and owner signatures are on Page 2.
  • 2Leaving Section 3 completely blank when there is no loan — California DMV instructions ask you to write "None" in Section 3 if there is no lienholder.
  • 3Forgetting the date the vehicle entered California in Section 5 — DMV uses this date to calculate registration fees and determine whether late penalties or use tax credits apply.
  • 4Submitting REG 343 for an out-of-state vehicle without a physical VIN verification (Form REG 31) and California smog check.

REG 343 example — what a filled-out form looks like

A fictional owner relocates from Oregon to San Diego with a 2021 Mazda CX-5 financed through a credit union and applies for California registration.

Section 1 — Vehicle information

Automobile · VIN JM3KFBCM••••••••• · 2021 · MAZDA · CX-5 · Body: 4D SUV · Fuel: G (Gas) · Odometer: 41,280 miles

Whole miles only, matching the VIN verification (REG 31) performed at the DMV.

Section 2 — Registered owner

SAMPLE, ALEX J · CA DL B123•••• · 400 Sample Way, San Diego, CA 92101 · County: San Diego

Physical address and California county are required to calculate local county/district fees.

Section 3 — Legal owner (lienholder)

EXAMPLE FEDERAL CREDIT UNION · PO Box 1000, Portland, OR 97208

Lists the lender holding the lien; write "None" if owned free and clear.

Section 5 — Date vehicle entered California

10/01/2026

New residents generally have 20 days after establishing residency to register an out-of-state vehicle without penalty.

Section 8 — Signature

Signed and dated by Alex J. Sample

Every registered owner must sign Section 8 on page 2 under penalty of perjury.

These values are made up. They are here to show what belongs on each line, not to be copied — every name, number, and address on your own REG 343 has to be your own.
