REG 343 form - Application for Title or Registration

Official name: Application for Title or Registration

Reviewed by the DMVCA editorial team · Content last verified September 15, 2026 · sourced to dmv.ca.gov

REG 343 is the Application for Title or Registration - the form that puts a vehicle onto the California register in your name. You file it when a vehicle is new to you and nobody is filing on your behalf: bought from a private seller, brought in from another state, rebuilt from salvage, or registered for the first time. Buy from a licensed dealer and the dealer usually files it for you - usually, not always, which is worth confirming before your deadline runs. It is the application; the title and plates are what come back.

Describes REG 343 rev 12/2022, checked September 15, 2026. The DMV revises forms at the same web address - if the copy you download shows a different revision, treat the section notes below as out of date and follow the form itself.

When you need it

When you need it

  • You bought a vehicle from a private seller and are registering it in your name.
  • You are registering a vehicle brought in from another state or from abroad.
  • A vehicle has been rebuilt from salvage and is returning to the road.
  • You are registering something for the first time - a trailer, an OHV, a specially constructed vehicle.

When you need a different form

When you need a different form

The commonest reason a form comes back is that it was the wrong one.

Use REG 227

The vehicle is already registered in California and the title is missing.

REG 343 puts a vehicle on the register. REG 227 replaces or transfers a title that already exists but cannot be produced - a different problem with a different form.

Use REG 262

You have the title in hand and only need the transfer and odometer sections.

A straightforward California-to-California sale runs on the endorsed title plus REG 262. REG 343 is for bringing a vehicle onto the register, not for handing one over.

Use REG 256

You are also claiming a use-tax or smog exemption.

REG 256 accompanies the application rather than replacing it - the exemption is declared there, the registration is applied for on REG 343.

What REG 343 asks for

What REG 343 asks for

Section by section, in plain language.

Vehicle identification
VIN, year, make, body type and - for an out-of-state vehicle - the last state of registration. This is the block a VIN verification (REG 31) supports when one is required.
Registered owner
True full name and address of each owner. How co-owners are joined matters: names joined by “AND” require every owner’s signature on a later transfer, while “OR” requires only one.
Legal owner / lienholder
The lender, if the vehicle is financed, including an electronic lienholder (ELT). Leaving it blank when a lender exists is what sends an application back.
California residency and use
When you obtained a California licence or became a resident, and when the vehicle was first brought into the state - the dates that decide whether it is a new-resident registration.
Disposition of out-of-state plates
Present when the vehicle arrives from elsewhere. The old plates do not move to another vehicle.
Signatures
Each registered owner signs. Co-owner rules follow the AND / OR choice made above.

From the fee schedule - never typed on this page.

The form itself is free. Nothing is charged for filing a REG 343. What you pay is the vehicle’s registration, assessed when the application is processed - these are the usual components, and they attach to the vehicle, not to the form.

  • Registration fee (base) $76
  • California Highway Patrol (CHP) fee $34
  • Vehicle license fee (VLF) 0.65% of value
  • Transportation improvement fee $33–$231

Questions

Frequently asked questions

What is a REG 343 form?
It is the California Application for Title or Registration - the form you file to put a vehicle on the register in your name, whether you bought it privately, brought it from another state, or are registering it for the first time.
I bought from a dealer - do I file the REG 343?
Usually not. An authorised California dealer handles the registration and gives you temporary tags. But not every dealer does, and the deadline is yours either way - if nothing has arrived and you cannot confirm the dealer filed, treat it as yours to file.
Do I need REG 343 to register an out-of-state car?
Yes. Bringing a vehicle in from another state is a registration application, so it runs on REG 343 - usually alongside a VIN verification and a smog certification. The out-of-state guide covers the full sequence.
Where do I submit REG 343?
At a DMV office or by mail, with the supporting documents and payment. It is not one of the DMV’s online transactions.
Is REG 343 the same as REG 227?
No, and they solve opposite problems. REG 343 brings a vehicle onto the register. REG 227 deals with a title that already exists but is missing - replacing it, or transferring the vehicle without it.
How much does REG 343 cost?
The form costs nothing to file. You pay the vehicle’s registration fees when the application is processed - the base registration fee, the CHP fee, the vehicle licence fee and the transportation improvement fee, plus use tax on a purchase. Those are charged on the vehicle, not on the form.
