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

Colorado sends renewal notices 60 days before your plate expires. You can renew through the state's online system at dmv.colorado.gov, by mail using the notice they sent you, or by visiting your county clerk's office in person. The online route is fastest — you'll get your new registration when ready and can print a temporary registration to use while waiting for the physical plate. Mail and in-person renewals take longer but work if you prefer not to use the website.

You'll need your current registration, proof of insurance, and payment for the renewal fee. Colorado's renewal fee varies based on your vehicle's age and weight, so the exact amount depends on what you're driving. If your vehicle has failed an emissions test or you've had a change in ownership since your last renewal, you may need to handle those issues before renewing your plate.

Key Takeaways

  • Online renewal at dmv.colorado.gov is the fastest option and lets you print a temporary registration when ready.
  • You must have current proof of insurance to renew, and Colorado verifies this electronically when you renew online.
  • Renewal fees depend on your vehicle's age and weight, so check the notice Colorado sent you or the website for your specific amount.
  • If your vehicle failed an emissions test or you've had an ownership change, you'll need to resolve those before your plate can renew.
  • Mail renewal takes two to three weeks; in-person renewal at your county clerk's office is usually same-day.

Renewing online through Colorado's DMV website

Go to dmv.colorado.gov and select "Renew Registration" from the main menu. You'll enter your vehicle identification number (VIN), license plate number, and the last four digits of your Social Security number. The system will pull up your current registration and show you the renewal fee based on your vehicle's specifications.

You'll need to upload or confirm your proof of insurance. Colorado requires liability coverage before you can renew. If you're renewing online, the system checks your insurance electronically through the state's verification system — you don't need to upload a document unless the system can't find your policy. Pay the renewal fee with a credit or debit card, and you'll receive a confirmation number when ready. Print the temporary registration that appears on your screen; it's valid for 30 days while you wait for your physical plate to arrive by mail.

Your new plate typically arrives within two to three weeks. The temporary registration is legal to use during this time, so you don't need to keep your old plate on the vehicle.

Renewing by mail using your renewal notice

Colorado mails a renewal notice to the address on file 60 days before your plate expires. This notice includes a form you can fill out and mail back with your payment. Write a check or money order for the renewal fee shown on the notice, and include a copy of your current proof of insurance. Mail everything to the address printed on the notice.

Processing mail renewals takes two to three weeks from the time Colorado receives your envelope. There's no tracking system for mail renewals, so if you're close to your expiration date, this method carries some risk — if your payment gets lost in the mail, your plate will expire before you know there's a problem. Mail renewal works best if you're renewing well before your expiration date.

Renewing in person at your county clerk's office

Find your county clerk's office location and hours on the Colorado Secretary of State website. Bring your current registration, proof of insurance, and payment for the renewal fee. Some county offices accept cash, checks, and cards; others may be cash or card only, so call ahead if you want to confirm what they take.

In-person renewal is usually same-day — you'll leave with your new registration and a temporary plate sticker or registration card depending on your county's process. You'll still need to wait for your physical plate to arrive by mail, but you can drive legally when ready after your visit. This option works well if you're renewing close to your expiration date and want to avoid the risk of mail delays.

What to do if your vehicle failed an emissions test

Colorado requires emissions testing for most vehicles in the Denver metro area and some other regions. If your vehicle failed its last test, you cannot renew your plate until you've had it repaired and passed a new test. The renewal system will flag this and prevent you from completing the transaction online.

Take your vehicle to a repair shop and have the emissions issue fixed. Once it passes the retest, the testing facility reports the pass to Colorado's system. You can then renew your plate normally. If you're unsure whether your vehicle needs an emissions test, check the notice Colorado sent you — it will say whether testing is required in your county.

Handling ownership changes and other complications

If you bought the vehicle since your last renewal and the title hasn't transferred to you yet, you cannot renew under the current registration. You'll need to complete the title transfer first through your county clerk's office, then renew the plate. Bring the signed title, bill of sale, and proof of insurance to your county clerk.

If your vehicle's information has changed — different engine, different body style, or a major repair that altered the vehicle — you may need to update your registration before renewing. The renewal system will flag this if it applies. Contact your county clerk's office if you're unsure whether a change you've made requires an update before renewal.

What happens if your plate expires before you renew

Driving with an expired plate is illegal in Colorado. If you miss your renewal date, you can still renew at any time, but you cannot legally drive the vehicle until the new registration is active. Renew as soon as you notice the expiration date has passed. If you're pulled over with an expired plate, you'll face a traffic citation.

If your plate expired more than a few months ago, contact your county clerk's office before attempting to renew online — there may be additional steps or fees involved. In-person renewal at your county clerk's office is the safest route if your plate is significantly overdue.

Frequently Asked Questions

Can I renew my Colorado plate if my insurance lapsed?

No. Colorado requires active liability insurance to renew. If your insurance lapsed, you'll need to get a new policy or reinstate your old one before you can complete the renewal. The online system checks this electronically, and mail or in-person renewal will also require proof of current coverage.

How much does a Colorado plate renewal cost?

The fee varies based on your vehicle's age and weight. Check the renewal notice Colorado sent you for your specific amount, or visit dmv.colorado.gov and enter your vehicle information to see the fee before you pay. Fees typically range from around $100 to $200, but this varies significantly by vehicle.

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

Update your address with Colorado's DMV before renewing. You can do this online at dmv.colorado.gov or at your county clerk's office. Once your address is updated, you can renew online without needing the physical notice — the system will have your current information on file.

Can I renew my plate if I'm out of state?

Yes. Online renewal at dmv.colorado.gov works from anywhere as long as you have your registration number, VIN, and proof of insurance. Mail renewal also works from out of state — just mail your renewal notice and payment to the address on the form. In-person renewal requires a visit to a Colorado county clerk's office.

What's the difference between a temporary registration and a permanent plate?

A temporary registration is a printed document or sticker valid for 30 days while you wait for your physical plate to arrive. Your permanent plate is the metal plate that arrives by mail and stays on your vehicle. Both are legal to use during the transition period.
