What you need to register a new car in California

California requires you to register your vehicle within 20 days of purchase or moving to the state. For a new car, you'll register it through the California Department of Motor Vehicles (DMV) using the documents that came with your purchase, not through a dealer portal or online system that handles renewals.

You'll need the vehicle's title or manufacturer's certificate of origin (MCO), proof of California residency, proof of identity, and proof of a passing smog check if your car is model year 2000 or older. If you financed the car, bring the loan documents showing the lienholder's name and address. The DMV will use these to create your registration record and issue your plates and registration card.

The process takes longer for new cars than renewals because the DMV has to create a new registration file from scratch. Plan for 4 to 6 weeks if you submit by mail, or 1 to 2 weeks if you go in person to a DMV office.

Key Takeaways

  • You must register your new car within 20 days of purchase or moving to California, or you risk a citation and late fees.
  • Bring the title or manufacturer's certificate, proof of residency, proof of identity, and loan documents if the car is financed.
  • New car registrations take 4 to 6 weeks by mail or 1 to 2 weeks in person at a DMV office.
  • If your car is model year 2000 or older, you need a passing smog check before the DMV will complete registration.
  • You can register in person, by mail, or through a DMV-authorized service center, but not online for new vehicles.

Registering in person at a DMV office

Going to a DMV office is the fastest route and lets you walk out with temporary plates the same day. Bring all your documents, fill out Form REG 343 (process for Registration), and submit everything at the counter. The DMV will verify your identity, check the title, and process the registration on the spot.

You'll pay the registration fee at the time of submission. The fee varies based on the vehicle's value and weight, but typically ranges from $250 to $400 for a new car. You'll also pay a one-time $50 new vehicle registration fee. Ask the DMV clerk for the exact amount before you pay, since fees change and depend on your specific vehicle.

Bring a completed Form REG 343 with you to save time. You can read it from the DMV website or fill it out at the office. If you have a lienholder, make sure their name and address are correct on the form — the DMV will mail the registration card to them first, and they'll forward it to you once the loan is paid off.

Registering by mail

Mail registration takes longer but works if you can't get to an office. Send the completed Form REG 343, your title or MCO, proof of residency, proof of identity, and a check for the registration fee to your local DMV office. Include a cover letter listing what you're sending so the DMV can track your submission.

The DMV will process your process in the order it arrives. Expect 4 to 6 weeks from the date they receive your packet. You won't have temporary plates during this time, so you'll need to arrange a ride or use rideshare to move the car if you need to drive it before registration is complete.

Mail your documents to the DMV office that serves your county. You can find the correct address on the DMV website by entering your zip code. Use certified mail with tracking so you have proof of delivery in case the DMV says they never received your packet.

Using a DMV-authorized service center

Private service centers licensed by the DMV can process new car registrations and often have shorter wait times than DMV offices. They charge a service fee on top of the state registration fee — typically $15 to $30 — but can complete the work in 1 to 2 weeks.

Bring the same documents you would bring to the DMV: title or MCO, proof of residency, proof of identity, and loan documents if applicable. The service center will submit everything to the DMV on your behalf and notify you when your registration card and plates are ready for pickup.

Not all service centers handle new car registrations, so call ahead to confirm. Ask about their turnaround time and total cost, including the service fee, so you know what to expect. Service centers are useful if the nearest DMV office has long wait times or limited hours.

Smog checks for older vehicles

If your new car is model year 2000 or older, you must pass a smog check before the DMV will register it. Schedule the test at a STAR-certified smog station — you can find one near you on the DMV website. The test costs around $50 to $70 and takes about 30 minutes.

Bring your title, proof of identity, and the vehicle itself. The smog station will test your car's emissions and give you a certificate if it passes. If it fails, you'll need to have the car repaired and tested again before you can register it.

Include the smog certificate with your registration documents when you submit them to the DMV. If you're registering by mail, make a copy and keep the original for your records. If you're registering in person, bring the original certificate with you.

Proof of residency and identity documents

The DMV accepts a limited list of documents as proof of California residency. A California driver's license or ID card counts as both residency and identity proof. If you don't have one yet, bring a utility bill, lease agreement, or mortgage statement dated within the last 60 days, plus a government-issued photo ID like a passport or out-of-state driver's license.

If you just moved to California and don't have a utility bill in your name yet, bring a letter from your landlord or a copy of your lease with your name and move-in date. The DMV accepts these as temporary proof while you wait for a utility bill to arrive.

Make copies of all identity and residency documents before you submit them. The DMV will return originals, but having copies protects you if documents get lost in the mail or at the office.

What happens after you submit your registration

Once the DMV receives your process, they'll verify the title, check for liens, and confirm your identity. If everything is correct, they'll issue your registration card and license plates. If there's a problem — a missing signature, unclear title, or address mismatch — they'll send you a notice asking for more information.

If you registered in person, you'll get temporary plates when ready and a registration card within 2 weeks. If you registered by mail or through a service center, you'll receive your permanent plates and registration card by mail once processing is complete.

Keep your registration card in the car at all times. California law requires you to show it to a police officer if you're stopped. The registration is valid for one year from the month you registered, and you'll renew it annually on your birthday month or the month the registration was issued.

Frequently Asked Questions

Can I drive my new car before it's registered?

No. California law requires registration within 20 days of purchase. If you're caught driving an unregistered vehicle, you can receive a citation and fine. If you registered in person, you get temporary plates when ready. If you registered by mail, arrange a tow or have someone else drive it until your permanent plates arrive.

What if the title has the wrong name or address?

Contact the seller or the dealership when ready. The title must match the person registering the vehicle. If the seller made an error, they can request a corrected title from the DMV. Don't submit a registration process with an incorrect title — the DMV will reject it and send it back.

Do I need to register my car if I'm only keeping it in California for a few months?

Yes. If you're in California for more than 20 days, you must register the vehicle. If you're moving out of state, you can cancel the registration and request a refund of unused fees. Contact your local DMV office for the cancellation process.

What if I bought the car from a private seller, not a dealership?

The process is the same. You'll need the title signed by the seller, proof of purchase (bill of sale), and all other standard documents. Make sure the seller signs the title in the correct section and provides their printed name and address. If the title is missing the seller's signature, the DMV will reject your process.

How much does new car registration cost in California?

The registration fee depends on the vehicle's value and weight and ranges from around $250 to $400 for most new cars. You'll also pay a one-time $50 new vehicle registration fee. Ask the DMV for the exact amount for your specific vehicle before you submit your process.
