What you need to do to renew your California registration

California requires you to renew your vehicle registration every year or every two years, depending on when your current registration expires. You can renew online through the California Department of Motor Vehicles (DMV) website, by mail, or in person at a DMV office. The online method is fastest — most renewals process within two weeks — and you can do it from home without an appointment.

Before you start, have your vehicle registration renewal notice handy. The DMV mails this to you about 60 days before your registration expires. If you cannot find it, you can still renew using your license plate number or vehicle identification number (VIN). You will also need a valid payment method: a debit card, credit card, or electronic check.

Key Takeaways

  • You can renew your California registration online at dmv.ca.gov, by mail, or at a DMV office, and online renewal usually takes two weeks.
  • The renewal notice the DMV mails you shows your renewal fee, which varies based on your vehicle's value and weight, not a flat statewide amount.
  • If you renew online or by mail before your expiration date, your new registration is valid when ready, even if the physical sticker arrives later.
  • You do not need a smog check to renew unless your vehicle is six years old or newer and your registration has lapsed, or if your county requires it for your vehicle type.

Renewing online through the DMV website

Go to dmv.ca.gov and select "Register a Vehicle" or "Renew Registration" from the homepage. You will be asked to enter your license plate number, VIN, or the renewal notice number printed on your notice. The system will pull up your vehicle record and show you the renewal fee.

Review the information on screen to make sure it is correct — vehicle type, weight, and value all affect the fee. If anything is wrong, you can correct it during renewal, though some changes (like a weight increase) may require a visit to a DMV office. Once you confirm the details, enter your payment information and submit. You will receive a confirmation number by email. Your new registration is valid when ready, even though the physical sticker will arrive by mail within two to three weeks.

Renewing by mail

Use the renewal notice the DMV sent you. Fill out the back of the notice with any changes to your vehicle information, sign it, and mail it with a check or money order to the address printed on the notice. Do not send cash. Include only the renewal notice itself — do not send your registration card or other documents unless the notice specifically asks for them.

Mail your renewal at least two weeks before your expiration date to avoid a lapsed registration. Once the DMV receives and processes your payment, your registration is valid when ready. The physical sticker will arrive separately within two to three weeks. If you do not receive your sticker within that time, contact the DMV to confirm your payment was received.

Renewing in person at a DMV office

Bring your renewal notice, a valid form of identification, and your payment method to any DMV office. You can walk in without an appointment, though wait times vary by location and time of day. Some offices are busier in the morning and on certain days of the week — calling ahead can tell you the current wait time.

At the counter, hand over your renewal notice and tell the clerk you are renewing. They will verify your information, collect your payment, and give you a temporary registration document valid for 30 days. Your permanent sticker will arrive by mail within two to three weeks. This method is useful if you need to make changes to your registration that the online system will not allow, or if you prefer to handle it in person.

Understanding your renewal fee

Your renewal fee is not the same for every vehicle in California. The DMV calculates it based on your vehicle's value (determined by a formula using the manufacturer's base price) and its weight. A newer luxury sedan will cost more to renew than an older compact car. Your renewal notice shows the exact amount you owe.

If you believe your fee is incorrect, you can request a reassessment through the DMV, though this requires documentation of your vehicle's actual value. Most people pay the amount on the notice. If you cannot pay the full amount at once, the DMV does not offer payment plans for registration renewal — you must pay in full before or on your expiration date to keep your registration current.

What to do if your registration has already expired

If your registration expired and you have not yet renewed, you can still renew online, by mail, or in person using the same methods described above. However, driving with an expired registration is illegal in California, even if you have submitted a renewal process. You risk a fine and a citation.

Renew as soon as possible. If you renew within a certain time after expiration (usually within a grace period that varies), you may owe only the standard renewal fee. If you wait much longer, you may owe a late fee in addition to the renewal fee. The DMV website or a phone call to your local office can tell you whether a late fee applies to your situation.

When you need a smog check before renewing

Most vehicles do not need a smog check to renew registration. However, you will need one if your vehicle is six years old or newer and your registration has lapsed for more than a few months, or if you live in a county that requires smog checks for your vehicle type. Some counties require checks for all vehicles; others only for vehicles over a certain age.

Your renewal notice will tell you whether a smog check is required. If it is, you must get one from a STAR-certified smog station before you can complete your renewal. The check costs between $30 and $70 depending on the station. Once you have the certificate, you can renew online or by mail by uploading or mailing the certificate along with your payment.

Frequently Asked Questions

Can I renew my registration before the expiration date?

Yes. You can renew up to six months before your registration expires. Renewing early does not change your expiration date — your new registration will expire one or two years from your current expiration date, not from the date you renew. This means renewing early does not give you extra time.

What if I moved and the renewal notice went to my old address?

You can still renew online using your license plate number or VIN without the notice. If you have not updated your address with the DMV, do that first through the DMV website or at an office. Update your address before renewing so future notices go to the correct location.

Do I need to renew my registration if I sold my car?

No. Once you sell your vehicle, you are no longer responsible for renewing its registration. You must notify the DMV of the sale by submitting a Notice of Transfer and Release of Liability (form REG 138) within five days. This protects you from liability if the new owner gets a ticket or is in an accident.

What happens if I renew but do not receive my sticker in the mail?

Contact the DMV and provide your confirmation number or renewal receipt. They can verify that your renewal was processed and resend your sticker if it was lost. In the meantime, your registration is valid — the sticker is just the physical proof. Keep your confirmation email or receipt in your vehicle as backup.

Can I renew someone else's registration for them?

Yes, if you have their renewal notice and payment method, you can renew online or by mail on their behalf. You cannot renew in person at a DMV office unless you have a power of attorney document. If you are renewing for an elderly parent or family member, online renewal is the simplest option.
