What you need to register a car in California

California registration requires you to submit proof of ownership, proof of California residency, and a completed process to the Department of Motor Vehicles (DMV). You'll also need to pay a registration fee, which varies based on the vehicle's value and weight. The DMV processes most registrations within two to three weeks if you submit everything correctly the first time.

You can register a vehicle in person at a DMV office, by mail, or online through the DMV website if your vehicle meets certain conditions. Online registration works only for vehicles that are already registered in California and don't require a smog check or other inspections. New residents registering a vehicle for the first time in California must go in person or mail documents.

Key Takeaways

  • California requires proof of ownership (title or bill of sale), proof of residency (utility bill or lease), and a completed process form to register any vehicle.
  • Registration fees depend on the vehicle's market value and weight, not just the purchase price, and are calculated using the DMV's fee schedule.
  • New vehicles and vehicles new to California require an in-person visit or mail submission; existing California registrations can renew online if no smog check is needed.
  • Most registrations take two to three weeks by mail or in person, but online renewals typically process within one week.

Documents you'll need to bring or submit

Start with the vehicle's title or a bill of sale if you don't have the title yet. If the title is held by a lender, the lender must sign the title before you can register. The DMV also requires proof that you live in California—a current utility bill, lease agreement, or mortgage statement dated within the last 60 days works. A driver's license or state ID showing your California address satisfies the residency requirement if it's current.

You'll complete form REG 343 (process for Registration) or form REG 343-V (the vehicle-specific version). If the vehicle is new, you'll also need the manufacturer's certificate of origin or the dealer's paperwork. For used vehicles, bring the previous registration if you have it. If you're registering a vehicle purchased from a private party, bring the signed bill of sale and the title with the seller's signature.

Smog checks are required for most vehicles over four years old, unless the vehicle is electric or meets other exemptions. You'll need the smog certificate before the DMV will complete registration. New vehicles and vehicles under four model years old don't need a smog check initially.

How to register in person at a DMV office

Find your local DMV office on the California DMV website and check whether you need an appointment. Most offices now require appointments, which you can book online. Bring all documents listed above, your completed process form, and payment for the registration fee. The DMV accepts cash, check, debit card, and credit card.

When you arrive, you'll check in and wait to be called. A DMV representative will review your documents, verify your information, and calculate your registration fee. If everything is correct, you'll pay and receive a temporary registration document on the spot. Your permanent registration card and license plates (if applicable) will arrive by mail within two to three weeks.

If you're registering a vehicle that requires license plates, the DMV will issue them at the office or mail them to you. Standard plates arrive with your registration card. Personalized or specialty plates take longer and may require additional fees.

Registering by mail or online

Mail registration works for most vehicles but takes longer than in-person service. Gather all required documents, complete your process form, and mail everything to the DMV address listed on the form. Include a check or money order for the registration fee. The DMV processes mail applications in the order received, typically within three to four weeks. Send your documents via certified mail if you want tracking.

Online registration through the DMV website is the fastest option but only works if your vehicle is already registered in California and doesn't need a smog check or other inspections. You'll log in with your driver's license number and date of birth, enter your vehicle information, and pay the fee with a debit or credit card. Your registration card arrives by mail within one week.

If you're registering a vehicle for the first time in California or your vehicle requires a smog check, you must use mail or in-person registration. The online system will tell you when ready if your vehicle is may be able to access.

Understanding California registration fees

California registration fees are based on the vehicle's market value, not what you paid for it. The DMV uses a fee schedule that assigns a value to each vehicle model and year. A 2020 Honda Civic, for example, has a set market value regardless of whether you bought it for $15,000 or $18,000. The fee is roughly 1.15% of that market value, plus a base fee and other charges.

The total registration cost includes the base fee (currently $46), the vehicle license fee (based on market value), a county fee, and any applicable smog check fee. Luxury vehicles and high-performance cars may have higher fees. Electric vehicles and some hybrid vehicles may have access to for reduced fees in some cases. The DMV website has a fee calculator where you can enter your vehicle's year, make, and model to see the exact cost before you register.

If you're registering a vehicle with an outstanding loan or lease, the lender or leasing company may have specific requirements about how the title is handled. Contact them before you register to confirm what they need from you.

Special situations: New residents and out-of-state vehicles

If you've just moved to California from another state, you have 20 days to register your vehicle with the California DMV. You'll need your out-of-state title or registration, proof of California residency, and a completed process. Some states' titles don't transfer directly to California; the DMV may issue you a new California title as part of the registration process. Bring your out-of-state registration or title to an in-person appointment or mail it with your process.

Vehicles registered in other states must pass a California smog check before registration, even if they passed inspection in their home state. Schedule the smog check before your appointment or before mailing your documents. The smog certificate must be dated within 30 days of when you submit your registration.

If you're registering a vehicle that was previously registered to someone else in California, you'll need the title signed by the previous owner. If the previous owner's name is still on the title and they're not present, you may need a notarized bill of sale or a power of attorney document.

What happens after you register

Once the DMV processes your registration, you'll receive a registration card and license plates by mail. The registration card shows your vehicle's registration number, expiration date, and the registered owner's name. Keep this card in your vehicle at all times. License plates should be mounted on the front and rear of your vehicle within 30 days of receiving them.

California registration expires on your birthday each year. You'll receive a renewal notice about 60 days before expiration. Most renewals can be done online if your vehicle doesn't need a smog check. If you don't renew by your expiration date, you'll face late fees and potential citations if you drive the vehicle.

If you sell your vehicle, notify the DMV within five days using form REG 138 (Notice of Transfer and Release of Liability). This protects you from liability for traffic violations or accidents involving the vehicle after the sale. The new owner must register the vehicle in their name within 10 days of purchase.

Frequently Asked Questions

How long does California registration take?

In-person and mail registration typically take two to three weeks from the date you submit your documents. Online renewal takes about one week. Processing time can be longer during peak periods or if the DMV needs to contact you for missing information.

Can I drive my vehicle before registration is complete?

You can drive with a temporary registration document issued at the DMV office on the day you register. If you register by mail, you should wait for your permanent registration card before driving. Driving without valid registration is a traffic violation.

What if I don't have the vehicle's title?

If the title is lost or never issued, contact the DMV to request a duplicate or explore for a new title. You may need to provide proof of ownership, such as a bill of sale or previous registration. This process takes additional time, so start early if you're missing the title.

Do I need to register a vehicle if I'm not driving it?

Yes. California law requires all vehicles to be registered, even if they're parked and not driven. If you own a vehicle you don't plan to use, you can request a non-operational registration, which costs less than standard registration but still requires renewal annually.

What if I move to a different California county?

You don't need to re-register your vehicle when you move within California. Your registration remains valid until the expiration date. Update your address with the DMV by completing form DL 43 (process to Amend a Driver License or Identification Card) or by updating your address online through the DMV website.
