What you need to do to renew in Colorado

Colorado lets you renew your vehicle registration online, by mail, or in person at a county clerk's office. You'll need your current registration card, proof that your vehicle passed the required emissions test (if your county requires one), and proof of insurance. The renewal notice arrives by mail about 30 days before your registration expires, and that notice includes a barcode you can use to renew online or by mail without visiting an office.

Online renewal is the fastest route: you go to the Colorado Department of Revenue's website, enter your vehicle information and registration number, upload a photo of your current insurance card, and pay the fee. The system tells you when ready whether your vehicle needs an emissions test. If it does and you haven't had one yet, you'll need to complete that before your registration officially renews.

By mail, you send your renewal notice, proof of insurance, and a check to the address printed on the notice. By person, you bring those same documents to your county clerk's office. Processing times vary: online usually takes a few days, mail takes one to two weeks, and in-person is often same-day or next-day.

Key Takeaways

  • You can renew online through the Colorado Department of Revenue website using the barcode on your renewal notice, which is the fastest method.
  • Proof of current insurance is required for all renewal methods, and you must show it as a photo or document at the time you renew.
  • Some Colorado counties require an emissions test before renewal; the online system will tell you whether yours does.
  • Your renewal notice arrives about 30 days before expiration and includes the barcode and mailing address you need for mail or online renewal.

Emissions testing requirements by county

Not all Colorado counties require emissions testing. The Colorado Department of Public Health and Environment requires testing in the Denver metro area (Denver, Adams, Arapahoe, Boulder, Douglas, Jefferson, and Weld counties) and in El Paso County. If you live in one of these counties, your vehicle must pass an emissions test before your registration renews.

You can take your vehicle to any Colorado emissions testing station. The test costs around $20 to $30 and takes about 15 minutes. Once you pass, the testing station sends the result directly to the Colorado Department of Revenue, so you don't need to bring a paper copy. If your vehicle fails, you have time to make repairs and retest before your registration expires.

If you live outside these counties, you do not need an emissions test to renew. The online renewal system will confirm this when you enter your vehicle information and county.

What happens if your registration expires

Driving with an expired registration is illegal in Colorado and can result in a traffic citation and fine. If you're pulled over, you may also be required to show proof that you've renewed or that you're in the process of renewing. The fine for expired registration varies but typically starts around $65 to $130.

If your registration has already expired and you haven't renewed yet, you can still renew through any of the three methods. There is no penalty for renewing late as long as you renew before you drive. However, if you were cited for expired registration, you'll need to resolve that ticket separately through the court system.

Costs and what's included in your renewal fee

Colorado registration renewal fees depend on your vehicle's age, weight, and type. A standard passenger vehicle typically costs between $100 and $150 to renew, but trucks, trailers, and older vehicles may have different fees. The exact amount appears on your renewal notice.

Your renewal fee covers your registration sticker (which goes on your license plate), your registration card, and the state's processing. If your county requires an emissions test, that fee is separate and paid directly to the testing station, not to the Department of Revenue.

Some Colorado counties also charge a local surcharge on top of the state fee. This amount is included in the total shown on your renewal notice, so you'll know the full cost before you pay.

Renewing online step by step

Go to the Colorado Department of Revenue's vehicle registration renewal page. Enter your vehicle identification number (VIN), license plate number, and the last four digits of your Social Security number or federal employer identification number. The system will pull up your registration record.

Review your vehicle and owner information for accuracy. If anything is wrong, you may need to visit a county clerk's office to correct it before renewing. Upload a clear photo of your current insurance card (front and back). The system will verify your insurance information with your insurance company.

Pay the renewal fee using a credit or debit card. You'll receive a confirmation number when ready. Your new registration sticker and card will arrive by mail within 7 to 10 business days. You can drive legally during this time as long as you have your confirmation number with you.

When to renew if your registration is expiring soon

You can renew up to 90 days before your registration expires. Renewing early doesn't change your expiration date — your new registration will expire one year from your current expiration date, not one year from when you renew. This means there's no advantage to renewing very early, but it's convenient if you want to get it done before a busy period.

If you're close to your expiration date and haven't received a renewal notice, check the Colorado Department of Revenue website or contact your county clerk's office. Renewal notices are mailed about 30 days before expiration, but mail can be delayed. You can renew without the notice as long as you have your vehicle information and current insurance.

What to do if you've moved or changed your address

If you've moved since your last registration, update your address with the Colorado Department of Revenue before renewing. You can do this online, by mail, or in person at a county clerk's office. Your renewal notice was mailed to your old address, so if you haven't received it, a change of address may be why.

When you renew online, the system will use the address on file with the Department of Revenue. If that address is incorrect, your new registration card will be mailed to the wrong place. Updating your address takes a few minutes online and prevents delays in receiving your new registration materials.

Frequently Asked Questions

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

Yes. If your vehicle is financed, you renew the same way as an owned vehicle. If your vehicle is leased, the leasing company typically handles registration renewal, so check your lease agreement or contact them directly. Some leasing companies require you to renew through them rather than on your own.

What if I don't have proof of insurance when I renew?

You must have current insurance to renew your registration in Colorado. If your insurance has lapsed, contact your insurance company to get proof of coverage before you attempt to renew. The online system will verify your insurance with your company, so make sure the information you provide matches your policy exactly.

Do I need to renew my registration if I'm selling my vehicle?

No. When you sell your vehicle, the new owner will register it in their name. You should notify the Colorado Department of Revenue that you've sold the vehicle so you're not responsible for it anymore. You can do this online or by mail.

How long does it take to get my new registration sticker in the mail?

After you renew online or by mail, your registration sticker and card arrive within 7 to 10 business days. If you renew in person at a county clerk's office, you may receive your sticker the same day or the next day. You can drive legally with your confirmation number while you wait for the physical sticker to arrive.

What if I lose my registration card before it arrives?

Contact your county clerk's office to request a replacement. You'll need to provide your vehicle information and proof of identity. A replacement card typically costs around $5 to $10 and takes a few days to arrive by mail.
