Register your out-of-state car in California by getting a California title, then registering it with the DMV

When you move to California or buy a car from another state, you cannot straightforward renew your out-of-state registration. California requires you to obtain a California title and register the vehicle with the California Department of Motor Vehicles (DMV) within 20 days of establishing residency or purchasing the car. The process involves transferring ownership through the DMV, paying registration fees, and passing a smog check in most cases.

The timeline matters: driving on an out-of-state registration past the 20-day window can result in citations and penalties. The good news is that the process is straightforward if you have the right documents and know which DMV office to visit or whether to handle it by mail.

Key Takeaways

  • You have 20 days from establishing California residency to register your out-of-state vehicle with the California DMV.
  • You will need the original title from your previous state, proof of California residency, proof of ownership, and a completed process for Title or Registration (Form REG 343).
  • Most vehicles require a smog check before registration, which must be performed by a STAR-certified station and costs between $30 and $70.
  • Registration fees depend on your vehicle's value and weight, but expect to pay between $200 and $400 for most passenger cars as a first-time California registration.
  • You can complete the entire process in person at a DMV office, by mail, or through an authorized vehicle registration service.

Gather your documents before visiting the DMV

The DMV will not process your registration without specific paperwork. Start by collecting your original title from your previous state — not a copy, but the actual document with the signature line. If you cannot locate it, you will need to request a duplicate from your previous state's motor vehicle department before you can proceed in California.

Next, gather proof of California residency. The DMV accepts a utility bill, lease agreement, mortgage statement, or property tax bill dated within the last 60 days. A driver's license or state ID showing your California address also works. You will also need proof of ownership, which is typically your bill of sale or purchase agreement showing the price paid and the date of purchase.

Complete the process for Title or Registration (Form REG 343), available on the California DMV website or at any DMV office. You will also need to fill out a Notice of Transfer and Release of Liability (Form REG 138) if you are transferring the title from a previous owner. Bring your current out-of-state registration and insurance information as well.

Get a smog check unless your vehicle is exempt

California requires a smog check for most vehicles before registration. The main exceptions are vehicles that are brand new (current model year), electric vehicles, and vehicles that are 1975 or older. If your vehicle was registered in California within the past two years, you may not need a new smog check, but you should verify this with the DMV.

To get a smog check, find a STAR-certified station in your area — the California Bureau of Automotive Repair maintains a searchable list on its website. The test takes about 30 minutes and costs between $30 and $70 depending on the station. You will receive a smog certificate that you must bring to the DMV or include with your mail-in process. The certificate is valid for 30 days, so time your test accordingly.

If your vehicle fails the smog check, you have options to repair it and retest, but this extends your timeline. Plan to schedule the smog check early in your registration process so you have time to address any issues.

Pay registration fees based on your vehicle's value

California registration fees are calculated using your vehicle's market value, not the price you paid. The DMV uses the National Automobile Dealers Association (NADA) guide to determine this value. For a typical passenger car, first-time registration fees range from $200 to $400, though luxury vehicles and trucks can be significantly higher.

The fee structure includes a base registration fee, a vehicle license fee (which varies by value), and county fees. You can estimate your fee on the California DMV website by entering your vehicle's year, make, and model. Bring a payment method — the DMV accepts cash, check, money order, credit card, or debit card depending on whether you are paying in person or by mail.

If you are registering a vehicle with a lien (meaning you still owe money on it), the lienholder's name must appear on the California title. Contact your lender to confirm they will release the lien once you pay off the loan, or ask them to provide a lien release document if you have already paid in full.

Choose between in-person, mail, or third-party registration services

You can register your vehicle at any California DMV office. Bring all your documents, the smog certificate, and payment. Wait times vary by location, but many offices now offer online appointment scheduling, which can significantly reduce your time in the office. Walk-ins are accepted, but appointments are faster.

If you prefer to avoid the DMV office, you can mail your process. Send Form REG 343, your original out-of-state title, proof of residency, the smog certificate, and payment to your local DMV office. Include a self-addressed stamped envelope if you want your documents returned. Processing by mail typically takes two to three weeks.

A third option is to use an authorized vehicle registration service. These private businesses handle the paperwork and DMV submission for you, charging a service fee (usually $50 to $150 on top of registration fees). This is useful if you are short on time or prefer not to visit the DMV yourself, but it costs more than handling it directly.

Handle the title transfer correctly to avoid delays

The title transfer is the most critical part of the process. If your out-of-state title has multiple owners listed, all owners must sign the back of the title in the designated signature area. If you are the sole owner, only your signature is needed. The signature must match the name on the title exactly — if it does not, the DMV will reject the process.

If the previous owner's name is still on the title and you have already purchased the vehicle, you will need a bill of sale or purchase agreement signed by the previous owner showing the transfer of ownership to you. This document proves you are the legitimate owner and protects you from liability for the vehicle's previous use.

Some states issue electronic titles rather than paper documents. If your previous state uses electronic titling, contact that state's motor vehicle department to request a paper title or an electronic title transfer to California. This can add one to two weeks to your timeline, so start this process as soon as you know you are moving to California.

What happens after you submit your registration

Once the DMV receives your process and payment, processing typically takes two to four weeks if you applied in person or by mail. You will receive your California registration card and license plates by mail. Until they arrive, you can drive on your out-of-state registration and a temporary registration receipt if you applied in person.

If you applied by mail and did not receive a temporary receipt, keep a copy of your mailed process and proof of payment as evidence that you have registered the vehicle. If the DMV needs additional information, they will contact you by mail or phone, so check your mailbox and answer calls from unknown numbers during the processing period.

Once your California registration arrives, remove your old license plates and install the new California plates. If you want to keep your old plates as a souvenir, some states allow this, but California requires you to return them or destroy them. You can keep them as a memento only if your previous state permits it.

Frequently Asked Questions

What if I do not have the original title from my previous state?

Contact your previous state's motor vehicle department and request a duplicate or certified copy of the title. This process varies by state and can take two to four weeks. Some states charge a fee for duplicates. You cannot register in California without this document, so start this request when ready if your title is missing.

Can I register my car before I move to California?

No. The DMV requires proof of California residency, which means you must have a California address. You can begin gathering documents before you move, but you cannot submit your registration process until you have established residency and can provide a utility bill, lease, or other proof of a California address.

What if my vehicle fails the smog check?

You can have the vehicle repaired and retested at the same or a different STAR-certified station. If it fails again, you may be may be able to access for a Smog Check Referee Program, which allows a second opinion at a referee station. Some repairs are covered by manufacturer warranty if the vehicle is recent. Plan extra time if you expect repairs may be needed.

Do I need to get new license plates, or can I keep my old ones?

California will issue you new license plates as part of your registration. You cannot keep your old plates on a California-registered vehicle. If you want to keep them as a memento, check whether your previous state allows you to retain them after registration transfer.

How long can I drive on my out-of-state registration in California?

You have 20 days from establishing residency or purchasing the vehicle. After that, driving on an out-of-state registration is a violation and can result in citations and fines. If you are close to the important date and your registration is not complete, contact the DMV to confirm your process was received and is being processed.
