Who should use it?
An owner applying for California title or registration, including an out-of-state vehicle application, can prepare this form. The required supporting documents and inspection depend on the vehicle and transaction; REG 343 is only one part.
When to use a different process
Do not use REG 343 as a replacement title request alone, a bill of sale, smog certification or proof that registration has been completed. It does not let AI determine a tax exemption or change a lender’s legal information.

Prepare the form with Faye
Faye starts with this question: What brings this vehicle to a California title or registration application: an out-of-state vehicle, a purchase, or another situation?
Answer in English, Spanish or Chinese. Faye maps confirmed facts to the editable fields of this English original as you answer. You can skip, correct or undo changes. Review all pages; signatures and any noneditable certification areas require the appropriate person.
Field guidance
Vehicle and owners
Vehicle and owners: distinguish vehicle type, hire use, commercial weight, co-owners and lessees. Confirm each AND/OR choice; copy names and addresses from the relevant records.
Lienholder and odometer
Lienholder and odometer: enter exact ELT listing details when applicable. Write None only after confirming no lien. Odometer has six digit fields and separate miles/kilometers choices, without tenths.
Dates and cost
Dates and cost: California entry, first operation, earliest work/license/residency and acquisition dates differ. Select one purchase/gift/trade category, using actual supplied cost/value; gift requires REG 256.
Conditional sections
Conditional sections: out-of-state tax/plate disposition, body modifications and military facts require explicit answers. A yes answer does not automatically certify a tax or fee exemption.
Information and documents to prepare
Prepare vehicle/title records, VIN, odometer and unit, all owners’ names and addresses, any lender/ELT information, acquisition documents and price/value, relevant California dates and any out-of-state tax record. Check DMV’s transaction checklist for title, smog and inspection requirements.
Signatures and review
Each owner signs the reverse side as the form requires. The AND/OR ownership connector affects later transfers but does not remove this application’s instruction for each owner to sign. Company signatures identify the business and authorized representative.
Where to submit the completed form
Take the reviewed application and the documents required for your transaction to California DMV using its applicable registration process. Fees, inspection and smog requirements are determined by that process. Fylune prepares a PDF and does not register the vehicle.
Common mistakes to avoid
Avoid mixing registered owner and lienholder, writing None without confirmed no lien, guessing entry/residency dates, filling purchase and gift together, adding tenths to the odometer or forgetting the second page’s vehicle identifiers.
