Colorado license plates renew every two years, and you can do it online, by mail, or in person at your county clerk's office

Your Colorado license plate renewal is tied to your vehicle registration, not your driver's license. The state sends you a renewal notice in the mail about 60 days before your plate expires — the expiration date is printed on the sticker on your current plate. You have three ways to renew: online through the Colorado Department of Revenue website, by mail using the renewal notice, or in person at your county clerk's office. The online method is fastest and costs nothing extra; by mail takes about two weeks; in person is when ready if you go during business hours.

You will need your current registration documents, proof of insurance, and payment for the renewal fee. The fee varies depending on your vehicle type and county, but typically ranges from around $100 to $200 for a standard passenger vehicle. If your vehicle has failed an emissions test or you have unpaid traffic violations or parking tickets, the state will not process your renewal until those issues are resolved.

Renewing online through the Colorado Department of Revenue

The Colorado Department of Revenue website allows you to renew your plate online if your vehicle and registration are in good standing. Go to the CDOR vehicle registration portal, enter your vehicle identification number (VIN) and current registration number, and answer a few questions about your vehicle. The system will show you the renewal fee and let you pay by credit card or debit card. You do not need to print anything — the state will mail your new registration documents and plate sticker to the address on file.

Online renewal works only if your vehicle has passed its most recent emissions test (if required in your county), you have no outstanding violations or tickets, and your insurance is current. If any of these conditions are not met, the system will tell you what needs to be fixed before you can proceed. Once you complete the transaction, you should receive your new registration and sticker within 7 to 10 business days.

Renewing by mail with your renewal notice

The renewal notice Colorado sends you in the mail includes a form you can fill out and mail back with your payment. Write a check or money order for the renewal fee (do not send cash), include a copy of your current proof of insurance, and mail everything to the address printed on the notice. The state processes mail renewals in the order they arrive, so send yours as soon as you receive it if you want it processed quickly.

Mail renewal typically takes 10 to 14 business days from the time the state receives your envelope. If you are close to your expiration date, mail is riskier because delays in postal delivery or processing can leave you with an expired plate. Keep a copy of your renewal notice and proof of mailing in case the state does not receive your envelope; you can then show law enforcement that you attempted to renew on time.

Renewing in person at your county clerk's office

Every Colorado county has a clerk's office that handles vehicle registration renewals. Bring your current registration, proof of insurance, and a valid ID, along with payment for the renewal fee. The clerk will verify your information, process your payment, and issue you a new registration document and plate sticker on the spot. This is the only method that gives you your new sticker when ready.

County clerk offices have different hours and locations, so check your county's website before you go. Some counties have multiple offices; you can use any of them. If you renew in person, you can drive legally with your old plate and new registration until the sticker arrives in the mail (which is not necessary if you received the sticker at the office). Bring all documents with you — if something is missing, you will have to come back.

What happens if your plate expires before you renew

Driving with an expired plate is a traffic violation in Colorado. If a police officer stops you, you can receive a ticket, and your vehicle can be impounded in some cases. The fine for an expired plate is typically $130 or more, depending on how long it has been expired. If you realize your plate has expired and you have not yet renewed, stop driving the vehicle and renew when ready — do not wait.

If you miss your renewal important date, you can still renew using any of the three methods above. There is no penalty for renewing late as long as you do it before you drive again. If you have already received a ticket for an expired plate, you will need to resolve that ticket separately through the court system; renewing your plate does not dismiss the citation.

Emissions testing requirements before renewal

Colorado requires emissions testing for vehicles in certain counties — primarily the Denver metro area and surrounding regions. If your vehicle is subject to testing, you must pass an emissions test before you can renew your registration. You can take your vehicle to any Colorado emissions testing station; the test costs about $25 and takes 10 to 15 minutes. The results are sent electronically to the state, so you do not need to bring a paper copy when you renew.

If your vehicle fails the emissions test, you have 60 days to fix the problem and retest. You can renew your registration during this window only if you pay a late renewal fee and agree to retest. Check your renewal notice to see whether your vehicle is in an emissions-testing county; if it is, schedule your test at least two weeks before your plate expires to leave time for repairs if needed.

Handling unpaid tickets or violations before renewal

If you have unpaid traffic tickets, parking tickets, or outstanding violations, Colorado will not process your renewal until those are resolved. The state's system checks for these automatically when you try to renew online or when the county clerk processes your process. You will receive a notice telling you which violations are blocking your renewal and how to pay them.

Contact the court or municipality listed on your violation notice to find out the amount owed and your payment options. Most courts accept payment online, by phone, or in person. Once you have paid, the state's system updates within one to two business days, and you can then complete your renewal. If you are unsure which violations are blocking your renewal, call your county clerk's office — they can look up your record and tell you exactly what needs to be cleared.

Frequently Asked Questions

Can I renew my Colorado plate if my vehicle registration is suspended?

No. If your registration is suspended due to unpaid tickets, emissions test failure, or insurance lapse, you cannot renew until the suspension is lifted. Contact the Colorado Department of Revenue or your county clerk to find out why your registration is suspended and what steps you need to take to restore it.

What if I move to a different county in Colorado?

You can renew your registration in your new county. Bring your current registration, proof of insurance, and proof of your new address (such as a utility bill or lease). The renewal fee may be different in your new county, so ask the clerk what you owe before you pay.

Do I need to renew my plate if I sell my vehicle?

No. When you sell your vehicle, the new owner will register it in their name. You do not need to renew the plate. If you are keeping the vehicle, you must renew before the expiration date on your current sticker.

How long does online renewal take?

The online transaction itself takes 5 to 10 minutes. Your new registration documents and sticker arrive by mail within 7 to 10 business days. You can drive legally with your old plate and registration until the new sticker arrives.

What if I lost my renewal notice?

You can still renew online or in person without the notice. If you renew by mail, call your county clerk's office and ask them to send you a duplicate renewal form, or go in person to renew instead.
