Form REG 343 is the core two-page California DMV title and registration application.

Field-by-field breakdown

What each section of CA Form 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 identification & motive power

17-character VIN, vehicle type, year, make, model, body type, license plate, axles, unladen weight (for pickups/trucks), fuel/motive power code, and whole-mile odometer reading.

Section 2 — Registered owner(s) & county

Full legal name(s) or business entity name, California DL/ID numbers, AND/OR ownership connector, physical street address, mailing address, and California county of residence.

Section 3 — Legal owner (lienholder / ELT)

Lienholder name, address, and Electronic Lien and Title (ELT) number — or write "None" if the vehicle is owned free and clear.

Sections 4 & 5 (Page 2) — Purchase cost & date vehicle entered California

Purchase date, purchase price or value, out-of-state sales tax paid, date the vehicle first entered California, and date it first operated in California.

Sections 6, 7 & 8 (Page 2) — Out-of-state title history & owner certification

Prior state of registration, plate disposition, commercial vehicle disclosures, and signatures of all registered owners under penalty of perjury.

Common mistakes to avoid

  • 1Printing or submitting only Page 1 — Form REG 343 must be completed on both sides, with the cost, California entry dates, and owner signatures on Page 2.
  • 2Leaving Section 3 blank when there is no loan — always write "None" in the Legal Owner section if no lender holds a lien.
  • 3Omitting the exact date the vehicle entered California in Section 5, which the DMV uses to determine registration fee start dates and use tax rules.
  • 4Filing REG 343 for a commercial pickup truck without a California weight certificate and physical VIN verification (Form REG 31).
