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

You can renew your Colorado vehicle registration without visiting an office if you renew before your current registration expires. The Colorado Department of Revenue Motor Vehicles Section handles renewals and sends renewal notices 60 days before expiration. You have three paths: renew online through the state's website, mail in your renewal notice with payment, or go to your county clerk's office in person.

The online route is fastest and costs nothing extra — no processing fee beyond the registration fee itself. Mail and in-person renewals work the same way but take longer. You cannot renew online if your vehicle has a lien, if you owe back registration fees, or if your vehicle failed inspection in the past year.

Key Takeaways

  • Colorado sends renewal notices 60 days before expiration; renew before that date to avoid late fees and keep your registration valid.
  • Online renewal through the state website is the fastest option and requires only your renewal notice number and vehicle identification number (VIN).
  • If you cannot renew online, mail your renewal notice and payment to your county clerk, or visit the clerk's office in person.
  • Registration fees depend on your vehicle's age and weight; the renewal notice shows the exact amount due.
  • Late renewal carries a penalty fee on top of your registration cost, so renew before your expiration date.

Renewing online through the Colorado Department of Revenue website

Go to the Colorado Department of Revenue Motor Vehicles online renewal portal. You will need your renewal notice (the document the state mails you) and your vehicle's VIN. The renewal notice includes a renewal notice number printed on the front — this is what you enter to start the process.

Enter your VIN, renewal notice number, and the last four digits of your vehicle identification number as it appears on your current registration. The system will pull up your vehicle record and show the renewal fee. Pay by credit card, debit card, or electronic check. Your new registration is valid when ready after payment, though the physical registration card arrives by mail within 7 to 10 business days.

Online renewal is not available if your vehicle has an active lien, if you have unpaid registration fees from prior years, or if your vehicle failed an emissions test in the past 12 months. The system will tell you if you are ineligible and direct you to the next step.

Mailing your renewal notice and payment

If you prefer not to renew online, mail your renewal notice with a check or money order to your county clerk's office. The renewal notice itself shows the mailing address for your specific county. Include the renewal notice, your payment, and nothing else — do not send your registration card or other documents.

Processing by mail takes 2 to 3 weeks from the date your county clerk receives it. Mail early enough that your payment arrives before your registration expires. If your renewal arrives after expiration, you will owe a late fee in addition to the registration fee. Keep a copy of your check or money order number for your records.

Renewing in person at your county clerk's office

Visit your county clerk's office with your renewal notice and payment method (check, money order, or card). Bring your current vehicle registration and your driver's license or ID. The clerk will process your renewal on the spot, and you can drive home with a temporary registration valid for 30 days while your permanent card is mailed.

County clerk offices have different hours and locations. Find your county clerk's office address and hours on the Colorado Secretary of State website. Some counties offer walk-in service; others require an appointment. Call ahead if you are unsure whether your office takes walk-ins.

What happens if you miss the expiration date

If your registration expires before you renew, you cannot legally drive the vehicle. You will owe a late fee on top of your registration fee. The late fee is typically $25 to $50, depending on how long past expiration you renew, but confirm the current amount with your county clerk.

Renew as soon as possible after expiration. You can still renew online, by mail, or in person using the same process. If you have been driving with an expired registration, you risk a traffic citation. Once your renewal is processed, your registration is valid from the date you renew, not from the original expiration date.

Registration fees and what affects the cost

Colorado registration fees are based on your vehicle's age and weight. A newer vehicle typically costs more than an older one. Your renewal notice shows the exact fee due for your vehicle. The state also charges a $10 registration process fee that applies to all renewals.

If your vehicle is financed or leased, the lender or leasing company may be listed as a lienholder on your registration. You cannot renew online if a lien is active. Contact your lender to have the lien removed, then renew. Some lenders handle this automatically when the loan is paid off; others require a written request.

Emissions testing requirements before renewal

Vehicles in the Denver metro area and some other Colorado counties must pass an emissions test before registration renewal. Your renewal notice will state whether your vehicle requires testing. You must complete the test and receive a passing certificate before you can renew your registration.

Schedule an emissions test at an authorized testing facility. The test costs around $25 to $30 and takes 15 to 20 minutes. Once you pass, the facility provides a certificate. If you renew online, the system checks whether you have a passing test on file. If you renew by mail or in person, bring the certificate with you or include it with your payment.

Frequently Asked Questions

Can I renew my registration before the renewal notice arrives?

You need your renewal notice number to renew online. If your notice has not arrived 60 days before expiration, contact your county clerk to request a duplicate or to renew in person. You can also call the Colorado Department of Revenue Motor Vehicles Section at 303-205-5600 to ask about your notice.

What if I moved and did not receive my renewal notice?

Update your address with the Colorado Department of Revenue before your renewal date. You can update your address online through the Motor Vehicles portal or by visiting your county clerk. Once your address is updated, you can renew online without the notice, or request a duplicate notice be mailed to your new address.

How long does my registration last after I renew?

Colorado vehicle registrations are valid for one year from the expiration date on your current registration. Your renewal notice shows the new expiration date. You will receive a new renewal notice 60 days before that date.

Can I renew if my vehicle has a lien?

No, you cannot renew online if a lien is active. Contact your lender to request lien release paperwork. Once the lien is removed from your registration record, you can renew through any method. This usually takes 1 to 2 weeks after the lender submits the release.

What if I sell my vehicle before renewal?

Do not renew if you have sold the vehicle. Instead, contact your county clerk to cancel the registration. Provide the buyer's information and the sale date. You may be due a refund for the unused portion of your registration, depending on how much time remains.
