California registration renewal happens online, by mail, or in person at the DMV, and you can start the process up to six months before your expiration date

California sends you a renewal notice in the mail 60 days before your registration expires. That notice contains your renewal code, which you need to renew online or by mail. You do not have to wait for the notice to arrive — you can renew as soon as six months before expiration. The fastest route is the DMV website at dmv.ca.gov, where most renewals take minutes. If you prefer mail or in-person service, both work, but mail takes longer and in-person visits require an appointment.

Your registration renewal cost depends on your vehicle's value, weight, and whether you have any violations or smog check requirements. California calculates the Vehicle License Fee based on the vehicle's market value, which changes yearly. You will also pay a base registration fee. If your vehicle is subject to smog testing, you must pass before you can renew.

Key Takeaways

  • You can renew online at dmv.ca.gov using your renewal notice code, and most renewals process the same day if you pay by credit or debit card.
  • If your vehicle requires a smog check, you must complete it before renewal and have the results available when you renew.
  • Renewing by mail takes two to three weeks, while in-person renewal at a DMV office requires an appointment booked through the website.
  • Late renewal fees explore if you drive on an expired registration, so renewing before your expiration date protects you from citations and fines.

Renewing online through the DMV website

The DMV website is the fastest way to renew. Go to dmv.ca.gov, select "Register a Vehicle," then choose "Renew Your Vehicle Registration." You will need your renewal notice code, vehicle identification number (VIN), and license plate number. The system will show you the renewal fee and any smog check requirement before you pay.

Payment is by credit card, debit card, or electronic check. Once you pay, the DMV issues a temporary registration document on screen that you can print or save to your phone. Your permanent registration card arrives by mail within two weeks. If you do not receive it after three weeks, contact the DMV through their website or call 1-800-777-0133.

Online renewal is not available if your vehicle has a lien, if you have unpaid violations or fees, or if your address on file does not match your current address. In those cases, you must renew by mail or in person.

Renewing by mail

To renew by mail, use the renewal notice the DMV sent you. Fill out the form on the back, include your payment, and mail it to the address shown on the notice. Do not send cash — pay by check or money order. Include a copy of your smog check results if your vehicle requires one.

Mail renewal takes two to three weeks from the time the DMV receives your envelope. The DMV recommends mailing your renewal at least three weeks before expiration to avoid driving on an expired registration. Once processed, your new registration card arrives by mail. If you need proof of renewal before the card arrives, you can print a temporary document from the DMV website using your renewal notice code.

Renewing in person at a DMV office

In-person renewal requires an appointment. Book one at dmv.ca.gov by selecting "Make an Appointment," then choosing "Vehicle Registration Renewal." You will need to provide your renewal notice code or vehicle information. Appointments are usually available within one to two weeks, though availability varies by location.

Bring your renewal notice, proof of smog compliance if required, and a valid ID. If someone else is renewing on your behalf, bring a signed power of attorney form (DMV Form REG 260). Payment is accepted by cash, check, debit card, or credit card. You receive your new registration card on the spot.

Smog check requirements and timing

Vehicles in California must pass a smog inspection every two years, with some exceptions. Your renewal notice will state whether your vehicle requires one. You must complete the smog check before you renew your registration — the DMV will not process renewal without proof of passing.

Smog checks are performed at authorized stations throughout California, not at the DMV. The test costs between $30 and $70 depending on your vehicle type and the station. Once you pass, the station provides a certificate or electronic record. If you renew online, you can upload the smog check results. If you renew by mail, include a copy. If you renew in person, bring the certificate or have the station send results electronically to the DMV.

Plan for smog testing at least one week before your renewal important date, since some stations have wait times and results take a day or two to process.

Late renewal penalties and expired registration

Driving on an expired registration is a violation in California. If you are stopped by law enforcement, you can receive a citation and fine. The fine for expired registration is typically $100 to $250, depending on how long the registration has been expired. You also risk vehicle impound if the registration is significantly overdue.

If your registration has expired, you can still renew through any of the three methods — online, mail, or in person. The DMV will charge a late fee in addition to your regular renewal cost. The late fee amount depends on how many months past expiration you are. Renewing as soon as possible stops the clock on additional penalties.

What to do if you cannot find your renewal notice

If you did not receive your renewal notice or cannot locate it, you can still renew. Go to dmv.ca.gov and select "Register a Vehicle," then "Renew Your Vehicle Registration." You can renew without the notice code by entering your VIN and license plate number instead. The system will pull up your vehicle record and show you the renewal fee.

If the online system cannot find your vehicle, call the DMV at 1-800-777-0133 or visit a DMV office in person. Bring your vehicle registration card and a valid ID. The DMV can look up your account and provide a renewal code or process the renewal on the spot.

Frequently Asked Questions

Can I renew my registration if my vehicle has a lien on it?

No, you cannot renew online if there is an active lien. You must renew by mail or in person at a DMV office. Bring proof that the lien has been satisfied, such as a lien release document from the lender. The DMV will update your record and process the renewal.

What happens if I renew but my smog check fails?

If you fail a smog check, you cannot renew until you pass. You must repair the vehicle and retest at an authorized station. Some stations offer a second test at a reduced cost if you fail the first time. Once you pass, you can renew your registration.

How long does a temporary registration last?

A temporary registration printed from the DMV website after online renewal is valid until your permanent registration card arrives by mail, typically within two weeks. It is not a separate document — it is proof that your renewal was processed. Keep it in your vehicle until the permanent card arrives.

Can I renew someone else's vehicle registration?

Yes, if you have a signed power of attorney form (DMV Form REG 260) from the vehicle owner. You can renew online, by mail, or in person. If renewing in person, bring the completed form and the owner's valid ID along with your own. Online and mail renewal do not require the form if you have the renewal notice code.

What if my address changed since my last registration?

Update your address before renewing. Go to dmv.ca.gov, select "Address Change," and update your record. Once the DMV processes the change, you can renew online. If you renew by mail or in person, bring proof of your new address, such as a utility bill or lease agreement, along with your renewal notice.
