What you need to register a car in California

California requires you to register your vehicle within 20 days of buying it or moving to the state. You'll register through the California Department of Motor Vehicles (DMV), either online, by mail, or in person at a DMV office. The process depends on whether you're registering a new purchase, transferring ownership, or renewing an existing registration.

For a new purchase, you'll need the vehicle's title or bill of sale, proof of California residency, proof of identity, and proof of vehicle insurance. If you're transferring a registration from another state, bring your out-of-state title or registration, the vehicle's odometer reading, and the same residency and identity documents. The DMV will assign you a license plate and send registration documents to your address.

Key Takeaways

  • You must register your vehicle within 20 days of purchase or moving to California, or face late fees and penalties.
  • The DMV accepts registration online, by mail, or in person — online is fastest if your vehicle qualifies and you have all documents ready.
  • You need proof of California insurance before the DMV will complete registration, and your policy must be active on the vehicle.
  • Registration fees vary based on the vehicle's value, weight, and type, and you'll pay them when you register or renew.
  • If you buy from a dealer, they often handle the paperwork and submit it to the DMV on your behalf, but you remain responsible if they don't.

Registering a vehicle you just bought in California

If you bought the car from a dealer, ask whether they will submit the registration paperwork to the DMV for you. Many dealers do this as part of the sale, but confirm it in writing and get a timeline. If the dealer is handling it, you'll still need to provide proof of insurance and sign the title or bill of sale before they submit anything.

If you bought the car from a private seller or the dealer won't handle registration, you'll submit the paperwork yourself. Start by getting the title signed by the seller and notarized if required (California requires notarization for some transfers). Then gather your proof of California insurance, a government-issued ID, and proof of residency such as a utility bill or lease agreement. You can register online through the DMV website if the vehicle is under 40 years old and you have all documents in digital form. Otherwise, mail the documents to your local DMV office or visit in person.

The DMV will send you a registration card and license plates within two to three weeks. Until they arrive, you can print a temporary registration document from the DMV website if you registered online, or the DMV will give you one at the office if you registered in person. Drive only with this temporary document — it's valid for 90 days.

Transferring registration from another state

When you move to California or buy a vehicle registered in another state, you must transfer the registration to California within 20 days. Bring your out-of-state title or registration, the vehicle's current odometer reading, and the same identity and residency documents you'd need for a new registration. You'll also need proof of California insurance.

The DMV will charge a transfer fee in addition to the California registration fee. Your out-of-state plates are no longer valid once you register in California, so don't drive with them after your registration is complete. The DMV will issue new California plates and send them to you.

Documents you must have before you register

The DMV will not complete your registration without proof of California insurance. Your insurance company must issue a policy that covers the specific vehicle you're registering, and the policy must be active on the date you register. Bring the insurance card, the declarations page, or a letter from your insurer showing the vehicle identification number (VIN), the policy number, and the effective date.

You'll also need a government-issued photo ID such as a driver's license, passport, or state ID card. If you don't have one, the DMV can issue a California ID at the same time you register. For proof of residency, bring a utility bill, lease agreement, mortgage statement, or bank statement dated within the last three months and showing your name and California address.

If you're registering a vehicle with a lien (a loan you're still paying off), the lienholder's name will appear on the title. You can still register the vehicle, but the lienholder must sign the title or provide written consent. Some lienholders handle this automatically; others require you to contact them first.

Registration fees and what they cover

California registration fees are based on the vehicle's market value, which the DMV calculates using a formula tied to the vehicle's age and type. A new vehicle costs more to register than an older one. The state also charges a vehicle license fee based on the vehicle's value, a registration processing fee, and sometimes a smog abatement fee. Total fees typically range from under $200 for older vehicles to several hundred dollars for new ones, but the exact amount depends on your vehicle.

You pay these fees when you register or renew. If you register late (after 20 days), the DMV adds a late penalty. Registration is valid for one or two years depending on your vehicle type; the DMV will tell you the renewal date when you register. You can renew online, by mail, or in person, usually without visiting an office if you renew on time.

Registering online versus in person

The DMV's online registration system is faster and requires no office visit. You can register online if your vehicle is under 40 years old, you have all required documents in digital form, and you're not transferring a title that requires notarization. Upload your proof of insurance, ID, residency, and the vehicle's title or bill of sale. The DMV will process it within a few business days and mail your registration card and plates.

Register in person if you need a notarized title, don't have digital copies of your documents, or prefer to handle everything at once. Visit your local DMV office with all required documents. Bring the original title or bill of sale, not a copy. Wait times vary by location and time of day; the DMV website shows current wait times for each office. You'll receive a temporary registration document on the spot and your permanent plates by mail within two to three weeks.

Registering by mail is an option if you prefer not to visit an office or register online. Mail your documents to your local DMV office along with a completed registration form. Include a check or money order for the registration fees. Processing takes longer by mail — typically three to four weeks — so use this method only if you have time before the 20-day important date.

What happens if you register late

If you don't register within 20 days of purchase or moving to California, the DMV charges a late penalty in addition to the regular registration fees. The penalty increases the longer you wait. You may also face fines if you're stopped by law enforcement while driving an unregistered vehicle. Some insurance companies will cancel your policy if the vehicle isn't registered, leaving you without coverage.

If you've missed the important date, register as soon as possible. Bring all the same documents you would for a timely registration. The DMV will calculate the late penalty based on how many days past the important date you are. You can register online, by mail, or in person; the method doesn't affect the penalty amount.

Frequently Asked Questions

Can I register my car online if I bought it from a private seller?

Yes, if the vehicle is under 40 years old and you have digital copies of all required documents, including the signed title, proof of insurance, ID, and proof of residency. The title must be signed by the seller and notarized if California law requires it for your type of transfer. If notarization is needed, you'll have to register in person or by mail instead.

What if the seller won't sign the title?

You cannot register the vehicle without the seller's signature on the title. If the seller refuses, you have no legal ownership and should not complete the purchase. If you've already paid, contact a lawyer or your local consumer protection office. Do not drive the vehicle without registration.

Do I need to register my car if I'm only visiting California?

If you're visiting temporarily and your vehicle is registered in another state, you don't need to register it in California as long as you're not establishing residency. However, if you move to California or stay longer than 20 days, you must register. If you're unsure whether you've established residency, contact your local DMV office.

What if I buy a car but haven't received the title yet?

If the seller or dealer hasn't given you the title, ask for a bill of sale or a temporary ownership document. You can register with a bill of sale in some cases, but the DMV will eventually need the signed title. Don't delay — register within 20 days using whatever document you have, then submit the title when you receive it.

Can I register a vehicle if I don't have a California driver's license?

Yes. You need a government-issued photo ID, which can be a passport, out-of-state driver's license, or state ID card. You don't need a California license to register a vehicle. If you want to drive legally in California, you'll need to get a California driver's license or ID card, which you can do at the same DMV office where you register.
