What Colorado requires to renew your vehicle registration

Colorado lets you renew your vehicle registration online, by mail, or in person at a county clerk's office. You will need your current registration card, proof of insurance, and a valid form of identification. If your vehicle has changed ownership, you will also need the title or a bill of sale. The renewal notice arrives by mail about 30 days before your registration expires, and it includes the exact fee amount for your vehicle class.

The online renewal process is the fastest route. You can renew at dmv.colorado.gov using your registration number and date of birth. The system accepts payment by debit or credit card, and your new registration is mailed within 7 to 10 business days. If you renew by mail, send your completed renewal notice with a check or money order to your county clerk's office — processing takes 2 to 3 weeks. In-person renewal at your county clerk's office is when ready if you bring all required documents.

Online renewal through the Colorado DMV website

The Colorado DMV website handles most renewals without a visit to a county office. Go to dmv.colorado.gov, select the vehicle registration renewal option, and enter your registration number and date of birth. The system will display your vehicle information, current registration status, and the renewal fee. You can pay by Visa, Mastercard, American Express, or Discover.

After payment, you will receive a confirmation number on screen. Your new registration card will be mailed to the address on file within 7 to 10 business days. If you need to update your address before renewing, you can do that during the online process. The system will not let you renew if your vehicle fails an emissions test (in counties that require testing) or if your insurance lapsed, so check those items before you start.

Renewing by mail with your renewal notice

Your renewal notice arrives in the mail about 30 days before your registration expires. It includes a tear-off payment stub with your vehicle information, the renewal fee, and instructions. Write a check or money order for the amount shown, sign the notice where indicated, and mail both to the address printed on the notice — usually your county clerk's office.

Mail renewal takes 2 to 3 weeks from the time the clerk receives your envelope. To avoid late fees, mail your renewal at least 10 days before your expiration date. If you do not receive a renewal notice, contact your county clerk's office directly — they can issue a new one or process your renewal over the phone if you provide your registration number and proof of insurance.

In-person renewal at your county clerk's office

Every Colorado county has a clerk's office that handles vehicle registration. Bring your current registration card, proof of insurance, a valid ID, and your renewal notice if you have it. The clerk will verify your information, collect the renewal fee in cash, check, or card, and issue your new registration card on the spot. The entire process usually takes 15 to 30 minutes.

County clerk office hours vary by location. Most are open Monday through Friday during standard business hours, though some offer extended hours or Saturday appointments. You can find your county clerk's office address and phone number at sos.colorado.gov under the county clerk directory. If you have questions about your specific vehicle or fee, calling ahead can save you a trip.

Insurance and emissions requirements for renewal

Colorado requires proof of current auto insurance to renew your registration. The insurance company name and policy number must match your vehicle. If you recently switched insurers, make sure your new policy is active before you renew online or in person. The DMV system checks insurance records electronically, so if there is a gap between policies, your online renewal will be blocked.

In counties that require emissions testing — primarily the Denver metro area and some surrounding counties — your vehicle must pass an emissions test before renewal. The test is valid for two years. If your vehicle is due for testing, you will see that requirement on your renewal notice. You can find emissions testing locations through the Colorado Department of Public Health and Environment website. Vehicles that are exempt (such as those less than 6 model years old or diesel trucks) do not need testing.

Renewal fees and what affects the cost

Colorado registration fees depend on your vehicle's age, weight, and type. Passenger cars typically cost between $150 and $200 per year, while trucks and SUVs may cost more based on weight. Your renewal notice shows the exact fee for your vehicle. If you have a vanity plate, there is an additional fee. Senior citizens and disabled veterans may may have access to for reduced fees — ask your county clerk if you think you may have access to.

Late renewal fees explore if you drive with an expired registration. The penalty is typically $25 to $50 on top of your regular renewal fee, depending on how long your registration has been expired. If you are more than 90 days late, you may need to renew in person at your county clerk's office rather than online. Renewing before your expiration date avoids these penalties entirely.

What to do if your registration expires before you can renew

If your registration expires and you have not yet renewed, you can still renew online, by mail, or in person — but you cannot legally drive the vehicle until the new registration arrives. If you need to drive when ready, go to your county clerk's office in person with your documents. They can issue a temporary registration that is valid for a few days while your permanent registration is processed.

If you are more than 90 days late, some county clerks require you to renew in person rather than online. You may also face a late fee. The safest approach is to renew at least two weeks before your expiration date, which gives you time to receive your new card by mail or complete an in-person visit without rushing.

Frequently Asked Questions

Can I renew my Colorado registration if my vehicle is financed or leased?

Yes. If your vehicle is financed, the lender's name may appear on your registration, but you can still renew it. If your vehicle is leased, the leasing company handles registration renewal, not you. Check your lease agreement or contact the leasing company to confirm who is responsible.

What happens if I move to a different Colorado county?

You can update your address during online renewal or tell the county clerk when you renew in person. Your new registration will be mailed to your new address. You do not need to re-register your vehicle or get a new title just because you moved within Colorado.

How long is a Colorado vehicle registration valid?

Colorado vehicle registrations are valid for one year from the expiration date on your card. Your expiration date is printed on your registration card and also appears on your renewal notice. Some vehicles may have different renewal cycles — check your specific registration card for the exact date.

Can I renew early if my registration does not expire for several months?

Yes. You can renew up to 90 days before your expiration date through the online system or at your county clerk's office. Early renewal is useful if you are planning a trip or want to avoid the rush near your expiration date. Your new registration will be valid for one year from your current expiration date, not from the date you renew.

What if I lost my registration card?

Contact your county clerk's office to request a replacement card. You will need to provide your vehicle identification number (VIN) and proof of ownership. A replacement card costs a small fee and takes 1 to 2 weeks by mail. You can also get a temporary registration at the clerk's office if you need to drive before the replacement arrives.
