What you need to do to register a car in California
To register a car in California, you submit documents to the Department of Motor Vehicles (DMV) that prove you own the vehicle, that it passed a smog test (if required), and that you live in the state. The DMV then issues you a registration card and license plates. You can do this in person at a DMV office, by mail, or through an approved third-party service like AAA or a car dealership.
The process takes different amounts of time depending on how you submit it. In-person registration at a DMV office usually takes a few weeks after your appointment. Mail-in registration can take four to six weeks. If you use a third-party service, they handle the paperwork and mail it to the DMV for you, which also takes several weeks.
You will need to pay a registration fee. The amount depends on the vehicle's value, age, and weight, so there is no single fee that applies to every car. You can estimate your fee on the DMV website before you go in.
Key Takeaways
- You need a title or proof of ownership, a completed process form, proof of California residency, and proof that your vehicle passed a smog inspection (if it is required for your car's year and type).
- The DMV charges a registration fee based on your vehicle's value and weight, which you can estimate on their website before you submit anything.
- You can register in person at a DMV office, by mail, or through a third-party service like AAA, and each method takes two to six weeks.
- If your vehicle is new or was recently purchased from a dealer, the dealer may handle the first registration for you.
- Out-of-state vehicles need a smog inspection before registration, but some newer cars are exempt from this requirement.
Documents you will need to bring or submit
Start by gathering your vehicle title or proof of ownership. If you bought the car from a dealer, you should have received the title in the mail or at the time of purchase. If you bought it from a private seller, the seller should have signed the title over to you. If you do not have the title yet, you can request a duplicate from the DMV.
You will also need a completed process for Registration (Form REG 343). You can fill this out online, read it from the DMV website and print it, or pick one up at a DMV office. The form asks for your name, address, vehicle information, and the odometer reading.
Bring proof of California residency. This can be a utility bill, lease agreement, mortgage statement, or government-issued ID with your current address. The document must show your name and address and be dated within the last 60 days (except for government IDs, which can be older).
If your vehicle requires a smog inspection, bring the smog certification from an authorized smog station. Most vehicles registered in California need a smog test every two years. New vehicles and some vehicles over 30 years old are exempt. If you are unsure whether your car needs one, the DMV website has a tool to check.
How to register in person at a DMV office
Go to the DMV website, find your local office, and schedule an appointment. Walk-ins are accepted at some offices, but appointment wait times are usually shorter. Bring all your documents: title, completed process form, proof of residency, and smog certification if required.
At your appointment, a DMV representative will review your documents, verify your information, and collect your registration fee. They will issue you temporary registration on the spot and mail your permanent registration card and license plates to your address within two to three weeks. If you need plates when ready, you can pay an extra fee for rush service at some offices.
If there is a problem with your documents — for example, a missing signature on the title or an address mismatch — the DMV will tell you what needs to be fixed before they can process your registration.
Registering by mail or through a third-party service
To register by mail, gather all your documents and send them to the DMV address listed on their website. Include a check or money order for the registration fee. Mail processing takes four to six weeks, and you will receive your registration card and plates by mail.
Many people use a third-party service instead because it is simpler than handling the paperwork yourself. AAA, car dealerships, and independent registration services can submit your documents to the DMV on your behalf. You bring your documents to them, pay their service fee (usually $15 to $50 on top of the DMV fee), and they handle the rest. This still takes the same amount of time as mailing it yourself, but you do not have to worry about whether you filled out the form correctly or included everything.
Some dealerships offer registration as part of the purchase, especially if you buy a new car. Ask whether this is included in your deal before you leave the lot.
Smog inspection requirements and exemptions
California requires most vehicles to pass a smog inspection before registration. The test checks whether your vehicle's emissions meet state standards. You take your car to an authorized smog station, pay a fee (usually $30 to $50), and receive a certificate if it passes.
Some vehicles do not need a smog test. New cars are exempt for their first four years. Vehicles that are 30 years old or older are exempt. Certain zero-emission vehicles like electric cars are also exempt. If you are registering a vehicle from out of state, it will need a smog inspection even if it would not need one in its home state.
If your vehicle fails the smog test, you will need to have it repaired and tested again. Some repair shops can help you identify what needs to be fixed. You cannot register your vehicle until it passes.
Registration fees and what affects the cost
The DMV registration fee is based on your vehicle's value, weight, and age. A new car costs more to register than an older one. A heavier vehicle costs more than a lighter one. The DMV website has a fee calculator where you enter your vehicle information and it shows you the exact amount you will owe.
In addition to the base registration fee, you may pay extra for license plates if you need them, for rush processing if you want your registration faster, or for a third-party service if you use one. If you are registering a vehicle for the first time in California, you will also pay for the initial license plates.
If you cannot pay the full fee at once, some DMV offices offer payment plans. Contact your local office to ask whether this is an option.
What to do if you bought a car from a private seller
When you buy a car from a private seller, the seller signs the title over to you and gives you the signed title document. You then follow the standard registration process: gather your documents, get a smog inspection if needed, and submit everything to the DMV.
Do not delay registering. California law requires you to register a vehicle within 20 days of purchase. If you do not register within that time, you may face late fees or penalties. If you are waiting for the title to arrive in the mail, contact the previous owner or the DMV to find out where it is.
If the seller refuses to sign the title or you cannot locate them, you can request a duplicate title from the DMV. This process takes longer and may require additional documentation, so it is best to get the signed title from the seller before completing the purchase.
Frequently Asked Questions
How long does it take to get my registration card and plates after I submit everything?
If you register in person at a DMV office, you receive temporary registration when ready and your permanent card and plates arrive by mail in two to three weeks. If you mail in your documents or use a third-party service, the entire process takes four to six weeks. You can drive with your temporary registration while you wait for the permanent plates.
Can I register my car if I have not paid off the loan yet?
Yes. The lender does not have to sign off on registration. However, the lender's name may appear on the title as a lienholder. You can still register the vehicle — just bring the title as it is. The registration belongs to you even though the lender has a financial interest in the car.
What happens if I register a car but it fails the smog test after I already submitted my process?
If your vehicle fails the smog test after you have submitted your registration, the DMV will not complete the registration until you provide a passing smog certificate. Always get the smog test done before you submit your registration documents to avoid this delay.
Do I need to register my vehicle if I only drive it occasionally?
Yes. Any vehicle you drive on California roads must be registered, regardless of how often you drive it. The only exception is if you store the vehicle and never drive it on public roads. If you do not plan to drive it, you can request a non-operational registration, which costs less than a standard registration.
Can someone else register my car for me?
Yes, if you give them a signed power of attorney form. You can read this form from the DMV website. The person you authorize can then submit your registration documents on your behalf. Many people use this option when they cannot get to a DMV office themselves.
