What you need to do to register an out-of-state vehicle in California

When you move to California or buy a car registered in another state, you must register it with the California Department of Motor Vehicles (DMV) within 20 days of establishing residency or taking ownership. You cannot legally drive an out-of-state car on California roads beyond that window using only your old registration — you need a California registration.

The process involves submitting specific documents to the DMV, paying registration fees, and passing a vehicle inspection in some cases. The exact steps depend on whether your car is new to you, whether it's still financed, and what condition it's in. Most people complete this through an in-person DMV visit, by mail, or through an authorized DMV service center.

Key Takeaways

  • You have 20 days from establishing California residency to register your out-of-state vehicle with the DMV, or you risk citations and penalties.
  • You will need your current out-of-state title, proof of California residency, a smog check certificate (in most cases), and proof of insurance to register.
  • Registration fees in California depend on your vehicle's value and weight, and you can estimate the cost using the DMV's online fee calculator before you go.
  • Some vehicles require a smog inspection before registration; others are exempt based on age, type, or previous registration history.
  • You can register by mail, in person at a DMV office, or through a private DMV service center, though processing times vary by method.

Documents you must bring or submit

Start by gathering your out-of-state title or registration document. This is the legal proof that you own the vehicle. If the title is held by a lender (because you financed the car), you will need written permission from the lender to register it in California, or the lender must submit the title themselves. Contact your lender if you are unsure whether they hold the title.

Next, you need proof that you live in California. The DMV accepts a utility bill, lease agreement, mortgage statement, or government-issued ID with a California address. The document must show your name and current address and be dated within the last 60 days.

You will also need proof of California auto insurance. Bring your insurance card or a declaration page from your policy showing your name, vehicle identification number (VIN), and coverage dates. California requires liability insurance before you can register any vehicle.

Finally, you need a smog check certificate in most cases. This is a separate inspection performed by a certified smog station, not the DMV. Vehicles older than 1975, electric vehicles, and some other categories are exempt. If your car requires a smog check, you must complete it before you submit your registration paperwork.

Smog check requirements and exemptions

California requires a smog inspection for most gasoline and diesel vehicles before you can register them. The inspection tests your vehicle's emissions to may support it meets state standards. You must use a station certified by the Bureau of Automotive Repair (BAR). Search for certified stations on the BAR website or ask your local DMV office for a list.

Vehicles exempt from smog checks include those manufactured before 1975, all-electric vehicles, vehicles registered in California for the first time if they are less than four model years old, and motorcycles. Diesel vehicles over 14,000 pounds also have different requirements. If you are unsure whether your vehicle is exempt, call the DMV or check the smog check information on their website.

The smog check costs between $30 and $70 depending on your vehicle type and the station. You will receive a certificate after passing. If your vehicle fails, you must repair it and retest before you can register. Some stations offer repair services, but you can also take your car to any mechanic.

Registration fees and how to calculate them

California registration fees are based on your vehicle's value and weight. The state uses a formula that calculates the fee as a percentage of the vehicle's market value, plus a base fee and weight fees. For a vehicle worth $10,000, you might pay $250 to $350 in registration fees, but this varies significantly based on the exact value and weight.

Use the DMV's online registration fee calculator on their website to get an estimate before you register. You will need your vehicle's VIN, which you can find on your out-of-state title, registration, or the dashboard on the driver's side of the windshield. The calculator gives you a close estimate of what you will owe.

You may also owe a one-time vehicle registration transfer fee and a smog abatement fee (around $8.50). If your vehicle is financed, you might owe additional fees. Bring a payment method — the DMV accepts cash, check, debit card, and credit card, though some service centers have restrictions.

How to register in person at a DMV office

Visit your local DMV office with all required documents: your out-of-state title, proof of residency, proof of insurance, and your smog check certificate. Bring your driver's license or ID as well. You can find your nearest DMV office and check wait times on the DMV website.

Many DMV offices now use an online appointment system. You can schedule an appointment on the DMV website, which usually reduces your wait time significantly. Walk-ins are accepted but may involve longer waits, especially at busy locations.

At the office, tell the staff member you are registering an out-of-state vehicle. They will review your documents, verify the VIN, and calculate your fees. You will pay on the spot and receive a temporary registration document. Your permanent registration and license plates arrive by mail within two to three weeks.

Registering by mail or through a service center

You can mail your registration documents to the DMV if you prefer not to visit an office in person. Gather all required documents, complete the process form (Form REG 343 for out-of-state registration), and mail them to the address listed on the DMV website for your county. Include a check or money order for the estimated registration fees.

Processing by mail typically takes four to six weeks. You will not receive a temporary registration, so you cannot legally drive the vehicle until your permanent registration arrives. This method works best if you have time before you need to drive the car regularly.

Private DMV service centers are another option. These are authorized businesses that handle certain DMV transactions, including vehicle registration. They charge a service fee on top of DMV fees (usually $15 to $50), but they often have shorter wait times and extended hours. Search online for "DMV service center near me" to find locations in your area.

What happens if you miss the 20-day important date

If you do not register your out-of-state vehicle within 20 days of establishing California residency, you risk a citation for driving an unregistered vehicle. The penalty can include fines starting at $250 and going higher depending on how long you have been driving unregistered. A law enforcement officer can also impound your vehicle.

If you have already missed the important date, register as soon as possible. The DMV will not penalize you for late registration — only law enforcement can issue citations. However, you remain at risk of being stopped until your California registration is complete. When you do register, bring all the same documents as if you were on time.

If you have received a citation for an unregistered vehicle, you may be able to dismiss it by showing proof that you have now registered the car. Bring your new California registration to traffic court or contact the court listed on your citation to ask about dismissal options.

Frequently Asked Questions

Can I drive my out-of-state car in California while I wait for my registration to arrive?

If you registered in person at a DMV office, you receive a temporary registration document that day, and you can drive legally while your permanent registration is in the mail. If you registered by mail, you cannot drive until your permanent registration arrives. With a service center, you typically get a temporary document the same day.

Do I need to get a California driver's license at the same time as registering my car?

No, vehicle registration and driver's license renewal are separate processes. However, if you have moved to California, you should get a California driver's license within 10 days. You can do both at the DMV on the same visit, but they are not required together.

What if my out-of-state title is in someone else's name?

You cannot register a vehicle in California unless your name is on the title. If the title is in another person's name, that person must sign the title over to you, or you must have a bill of sale and written permission from the title holder. Some states require the title to be officially transferred before you can register elsewhere.

Will I get California license plates right away?

No. You will receive a temporary registration document if you register in person, but your permanent registration and license plates arrive by mail in two to three weeks. You can drive legally with the temporary document during that time.

What if my vehicle fails the smog check?

You must repair the vehicle and pass a retest before you can register. The smog station will tell you what repairs are needed. You can take the car to any mechanic, not just the station where it failed. Once it passes, you get a new certificate and can proceed with registration.
