Colorado registration renewal happens online, by mail, or in person at your county clerk's office

Colorado sends renewal notices 30 to 60 days before your registration expires. You can renew through the Colorado Department of Revenue's online portal, by mail using the notice they send you, or by visiting your county clerk's office in person. The online route is fastest — most renewals process within minutes. Mail takes one to two weeks. In-person renewal at the county clerk is when ready if you bring all required documents.

You do not need to renew in the county where you registered the vehicle originally. Any county clerk's office in Colorado will handle the renewal. If you move out of state or your vehicle is no longer roadworthy, you can also surrender your plates and cancel the registration without renewing.

Key Takeaways

  • Colorado mails renewal notices 30 to 60 days before expiration; check your mail or log into your online account if you do not receive one.
  • Online renewal through the Department of Revenue website is the fastest method and works for most vehicles, though some situations require in-person visits.
  • You will need your current registration card, proof of insurance, and payment for the renewal fee, which varies by vehicle weight and county.
  • If your registration has already expired, you can still renew by mail or in person, but driving with expired plates is illegal and can result in a traffic stop.
  • County clerk offices handle renewals in person and can answer questions about your specific vehicle or registration status on the spot.

What you need before you renew

Gather your current registration card, proof of current auto insurance, and your vehicle identification number (VIN). Colorado requires proof that your vehicle is insured at the time of renewal. Your insurance company can provide a current declarations page or proof-of-insurance letter. If you have a lien on the vehicle, the lienholder's information may already be on file, but confirm this before renewing.

If your vehicle has changed ownership since the last registration, you will need the title or a bill of sale. If you have made changes to the vehicle — such as adding a trailer or changing the gross vehicle weight rating — bring documentation of those changes. For commercial vehicles or those registered under a business name, bring the business registration or EIN.

Renewing online through the Colorado Department of Revenue

Visit the Colorado Department of Revenue's vehicle registration portal at dor.colorado.gov. Log in with your driver's license number and date of birth, or create an account if you do not have one. Search for your vehicle by VIN or license plate number. The system will show your current registration status and expiration date.

Review the renewal information on screen. The system will calculate your renewal fee based on your vehicle's weight and any applicable county fees. Pay by credit card, debit card, or electronic check. Once payment processes, you will receive a confirmation number when ready. Your new registration card will be mailed to the address on file within 7 to 10 business days. You can print a temporary registration receipt from the confirmation page if you need proof of renewal before the card arrives.

Online renewal does not work if your vehicle has a salvage title, if you are renewing a commercial vehicle for the first time, or if your registration was suspended or revoked. In those cases, visit your county clerk's office in person.

Renewing by mail

Use the renewal notice Colorado sends you. Fill out the form, include a check or money order for the renewal fee (made payable to the county treasurer), and mail it to the address printed on the notice. Include a copy of your proof of insurance. Do not send cash.

Mail your renewal at least two weeks before your registration expires to allow time for processing and delivery. Send it to the county clerk's office listed on your notice, not to the state office. Processing takes one to two weeks after the office receives it. Your new registration card will be mailed to you separately. If your renewal notice is lost or you did not receive one, contact your county clerk's office to request a duplicate or to renew in person.

Renewing in person at your county clerk's office

Visit any county clerk's office in Colorado with your current registration card, proof of insurance, and payment. Bring your driver's license or ID as well. The clerk will verify your information, calculate the renewal fee, and process the renewal on the spot. You will receive your new registration card when ready or within a few minutes.

County clerk hours and locations vary. Search "county clerk near me" plus your city name, or visit your county's official website to find the office closest to you and confirm hours. Some offices are open evenings or Saturdays; others are not. If you are renewing a vehicle with a salvage title or a commercial vehicle, call ahead to confirm the office can handle your specific registration type.

Renewal fees and what affects the cost

Colorado registration fees are based on your vehicle's dry weight — the weight without fuel, passengers, or cargo. Heavier vehicles cost more to renew. Fees also vary slightly by county. The state publishes a fee schedule on the Department of Revenue website, but the exact amount depends on your vehicle's weight class and your county of residence.

If you registered your vehicle in one county and have since moved to another, you renew in your new county. The fee may change based on the new county's rates. If you own a vehicle registered to a business address and that business has moved, update your address before renewing to avoid delays. Some vehicles — such as those registered as antique or classic — may have lower renewal fees; check the fee schedule or ask your county clerk if your vehicle qualifies.

What to do if your registration has already expired

You can still renew even after the expiration date has passed. Driving with expired plates is illegal and can result in a traffic stop and citation. Renew as soon as possible using any of the three methods above. There is no grace period in Colorado, so the day after expiration, your registration is no longer valid.

If you are renewing more than 30 days after expiration, some county clerks may require you to renew in person rather than by mail or online. Call your county clerk's office to confirm before attempting an online or mail renewal. If your vehicle was not insured during the expired period, you may need to provide proof of reinstatement of insurance before the renewal is processed.

Frequently Asked Questions

Can I renew my registration if I just bought the vehicle?

No. You must first register the vehicle in Colorado using the title and bill of sale. Once the initial registration is complete, you can renew it like any other vehicle. This process takes longer than a renewal and requires an in-person visit or mail submission to your county clerk's office.

What happens if I move out of state before my registration expires?

You do not need to renew your Colorado registration. Contact your county clerk to surrender your plates and cancel the registration. Register your vehicle in your new state according to that state's requirements. If you keep the vehicle in Colorado, you must renew the registration regardless of where you live.

Do I need a vehicle inspection to renew my registration?

Colorado does not require a safety or emissions inspection for most passenger vehicles at renewal time. However, if your vehicle is 25 years old or older, you may be exempt from certain requirements. Check with your county clerk if you are unsure whether your vehicle needs an inspection.

Can someone else renew my registration for me?

Yes, if you renew by mail or online. For in-person renewal, the person visiting the clerk's office will need your registration card and proof of insurance, but does not need a power of attorney. If you want someone else to handle renewals regularly, you can authorize them through the Department of Revenue's online portal.

What if my registration card is lost or damaged?

Contact your county clerk's office to request a duplicate. You can renew your registration at the same time. Bring your driver's license and proof of insurance. There may be a small fee for a duplicate card, separate from the renewal fee.
