Colorado vehicle registration renews every year or two, depending on your vehicle type and when you last registered it

Colorado issues registration certificates that expire on a date printed on your current registration card. You can renew online through the Colorado Department of Revenue website, by mail, or in person at a county clerk's office. Most renewals take 10 to 15 business days if you mail them in, and same-day service is available at some county offices if you go in person. You'll need your current registration card, proof of insurance, and payment for the renewal fee — which varies based on your vehicle's age, weight, and type.

The state sends renewal notices about 30 days before your registration expires, but you don't have to wait for the notice to renew. You can renew up to six months early. If your registration has already expired, you can still renew it, but you'll owe a late fee on top of the standard renewal cost.

  • You can renew online at the Colorado Department of Revenue website, by mail, or at your county clerk's office — online is fastest for most people.
  • You'll need your current registration card, proof of current auto insurance, and the renewal fee amount, which depends on your vehicle's weight and type.
  • Renewal notices arrive about 30 days before expiration, but you can renew up to six months early to avoid the rush.

Renewing online through the Colorado Department of Revenue

The fastest way to renew is through the Colorado Department of Revenue's online portal at dmv.colorado.gov. You'll log in with your driver's license number and date of birth, then follow the prompts to confirm your vehicle information and insurance coverage. The system calculates your renewal fee based on your vehicle's details and accepts payment by credit card or debit card. You'll receive a temporary registration number when ready, and your new registration card arrives by mail within 10 to 15 business days.

Online renewal works only if your vehicle information hasn't changed since your last registration. If you've moved, changed your name, or need to update your vehicle's information, you'll need to renew by mail or in person instead.

Renewing by mail or at a county clerk's office

If you prefer to renew by mail, send your completed renewal notice (the one Colorado sends you), your current registration card, proof of insurance, and a check or money order to your county clerk's office. Include a return envelope with postage. Processing takes 10 to 15 business days from the date the clerk receives your packet. You can find your county clerk's mailing address on the renewal notice or on the Colorado Department of Revenue website.

For same-day renewal, visit your county clerk's office in person during business hours. Bring your current registration card, proof of insurance, and payment (cash, check, or card — policies vary by county). Some offices offer walk-in service; others require an appointment. Call your county clerk ahead of time to confirm their hours and whether you need to schedule a time slot.

What proof of insurance Colorado requires

Colorado requires proof that your vehicle has active liability insurance before you can renew your registration. You can provide this as a printed insurance card, a digital copy on your phone, or a letter from your insurance company. The proof must show your current policy number, the vehicle identification number (VIN), and a policy effective date that covers the date you're renewing.

If you've switched insurance companies since your last registration, make sure your new policy is active before you renew. If you let your insurance lapse, you'll need to get a new policy and proof of coverage before the county clerk or online system will process your renewal.

Understanding Colorado registration fees

Colorado registration fees are based on your vehicle's age, weight, and type. A newer passenger car typically costs less than an older truck or an RV. The state also charges a $10 registration fee that applies to all vehicles, plus county-specific fees that vary depending on where you register. Your renewal notice lists the exact amount you owe, or you can estimate the cost on the Colorado Department of Revenue website by entering your vehicle's year, make, and weight.

If your registration has expired, Colorado adds a late fee. The amount depends on how long your registration has been expired, but it's typically $25 to $50 on top of your renewal fee. Renewing as soon as you notice the expiration date has passed keeps this extra cost as low as possible.

What to do if your registration has expired

If you're driving with an expired registration, you can be stopped and cited by law enforcement. Colorado allows a grace period of up to 30 days after expiration for you to renew without penalty, but after that the late fee applies. You should renew when ready if you notice your registration has lapsed.

You can renew an expired registration using any of the three methods — online, by mail, or in person. Online renewal is often fastest because you'll get a temporary registration number right away that you can print or show on your phone if you're stopped. If you renew in person at a county clerk's office, ask for a temporary registration receipt to carry with you until your new card arrives.

Renewing a registration for a vehicle you recently bought

If you've recently purchased a vehicle and received a temporary registration or a registration from the dealer, you'll need to register it in your name with Colorado before you can renew it. This is a separate process from renewal and requires a bill of sale, proof of ownership, and proof of insurance. Once Colorado issues your first registration, you can then renew it using the standard renewal process.

Contact your county clerk's office or the Colorado Department of Revenue for instructions on registering a newly purchased vehicle. The process typically takes one to two weeks, and you can drive on the temporary registration during that time.

Frequently Asked Questions

Can I renew my Colorado registration before the expiration date?

Yes. Colorado allows you to renew up to six months before your registration expires. This is useful if you want to avoid the rush near the expiration date or if you're planning a trip and want a fresh registration card.

What happens if I drive with an expired registration in Colorado?

You can be cited by law enforcement. Colorado gives a 30-day grace period after expiration before late fees explore, but driving with an expired registration is still a violation. Renew as soon as you notice the expiration date has passed.

How long does it take to get my new registration card after I renew online?

You'll receive a temporary registration number when ready that you can use right away. Your physical registration card arrives by mail within 10 to 15 business days. If you need the card sooner, you can visit a county clerk's office to request an expedited card for an additional fee.

Do I need to renew my registration every year in Colorado?

Most vehicles renew annually, but some vehicle types renew on a two-year cycle. Your current registration card shows your expiration date. Check the card or your renewal notice to confirm whether you renew every year or every two years.

What if my vehicle information has changed since my last registration?

If you've moved, changed your name, or made changes to your vehicle, you cannot renew online. Renew by mail or in person at your county clerk's office instead. Bring documentation of the change — such as a new driver's license for a name or address change — along with your current registration card and proof of insurance.
