Connecticut registration renewal happens online, by mail, or in person at a DMV office

Connecticut allows you to renew your vehicle registration through three routes: the Connecticut DMV website (ct.gov/dmv), by mail using the renewal notice you receive, or by visiting a DMV office in person. Most renewals can be completed online without leaving home. You'll need your current registration card, vehicle identification number (VIN), and a valid payment method. The process takes about 10 minutes online.

Your renewal notice arrives in the mail about 30 days before your registration expires. The notice includes your renewal number and instructions for each method. If you don't receive a notice, you can still renew online using your VIN and driver's license number, though having the notice makes the process faster.

Key Takeaways

  • Connecticut sends renewal notices 30 days before expiration, and you can renew online, by mail, or in person at any DMV office.
  • Online renewal requires your registration number or VIN, a valid driver's license, and takes about 10 minutes.
  • Mail renewal uses the prepaid envelope included with your notice and takes 7 to 10 business days after mailing.
  • In-person renewal at a DMV office requires your registration card, proof of insurance, and a valid ID, and is processed the same day.
  • Connecticut registration costs vary by vehicle weight and type; passenger vehicles typically renew for $135 to $155 every two years.

Renewing online through the Connecticut DMV website

Go to ct.gov/dmv and select "Renew Vehicle Registration" from the main menu. You'll enter either your renewal number (from your notice) or your VIN and driver's license number. The system will pull up your vehicle information and current registration details. Review the information for accuracy—if anything is wrong, you'll need to correct it in person at a DMV office instead of online.

After confirming your details, you'll pay the renewal fee using a credit or debit card. Connecticut does not accept checks or cash online. Your new registration card will be mailed to the address on file within 7 to 10 business days. You can print a temporary registration receipt when ready after payment if you need proof of current registration before the card arrives.

Renewing by mail with your renewal notice

Your renewal notice includes a prepaid return envelope. Write a check or money order for the renewal fee, sign the back of your registration card, and mail both the notice and card in the envelope provided. Do not include your driver's license or other documents—the notice and card are all that's needed. Mail it at least two weeks before your registration expires to account for postal delays.

Processing takes 7 to 10 business days after Connecticut DMV receives your envelope. Your new registration card will be mailed to your address on file. If you need to drive before the new card arrives, keep your renewal notice as proof of current registration—it's valid until your new card is received.

Renewing in person at a Connecticut DMV office

Visit any Connecticut DMV office with your current registration card, proof of insurance, and a valid photo ID (driver's license, passport, or state ID). Bring your renewal notice if you have it, though it's not required. You can renew at any DMV location, not just the one closest to you. Walk-ins are accepted, but you can also schedule an appointment online at ct.gov/dmv to skip the wait.

Processing is when ready—you'll receive your new registration card before you leave the office. This is the fastest method if you need your new card right away. Connecticut DMV offices are open Monday through Friday during standard business hours; some locations have extended hours on certain days. Check the DMV website for your nearest office location and current hours.

What happens if your registration expires before you renew

Driving with an expired registration in Connecticut is a violation. If you miss your expiration date, you can still renew online, by mail, or in person using the same process—there is no separate "late renewal" procedure. However, you should not drive the vehicle until it's renewed. If you're stopped by police with an expired registration, you may receive a ticket.

If your registration has been expired for more than a few days and you haven't yet renewed, go to a DMV office in person rather than waiting for mail processing. This ensures your vehicle is legal to drive as quickly as possible. Bring the same documents you would for a standard renewal: registration card, proof of insurance, and valid ID.

Registration renewal costs and what's included

Connecticut registration renewal fees depend on your vehicle's gross vehicle weight rating (GVWR). Passenger vehicles typically renew for $135 to $155 every two years. Motorcycles cost less; commercial vehicles and trucks cost more based on weight. Your renewal notice shows the exact fee for your vehicle. Connecticut does not charge separate inspection fees at renewal—vehicle inspections are handled separately through authorized inspection stations.

Your renewal fee covers two years of registration. Connecticut does not offer one-year registrations for standard passenger vehicles. If you sell your vehicle before the two-year period ends, you can transfer the unused portion of your registration to a new vehicle, though this requires an in-person visit to a DMV office.

Proof of insurance and registration address changes

Connecticut requires proof of current auto insurance to renew your registration. If you're renewing online or by mail, the DMV verifies your insurance electronically through the state's insurance database—you don't need to submit a document. If your insurance has lapsed or if you're switching insurers, make sure your new policy is active before you renew. If the DMV cannot verify coverage, your online renewal will be rejected and you'll need to renew in person with a current insurance card.

If you've moved since your last registration, update your address before renewing. Online renewal will use your current address on file with the DMV. If your address in the DMV system is wrong, you can update it online through your DMV account or by visiting a DMV office. Mail renewal uses the address on your renewal notice, so if that's incorrect, call the DMV at 860-263-5700 to request a corrected notice before mailing.

Frequently Asked Questions

Can I renew my registration if my vehicle inspection is expired?

Yes. Connecticut registration and vehicle inspection are separate. You can renew your registration even if your inspection is expired, but you cannot legally drive the vehicle until both are current. Schedule your inspection at an authorized inspection station and renew your registration separately through the DMV.

What if I lost my renewal notice?

You don't need the notice to renew. Go to ct.gov/dmv and select online renewal, then enter your VIN and driver's license number instead of your renewal number. The system will pull up your vehicle and allow you to proceed. You can also renew in person at any DMV office with your registration card and ID.

How long is my registration valid after I renew?

Connecticut registrations are valid for two years from the expiration date of your previous registration. Your new registration card will show the new expiration date. You'll receive a renewal notice about 30 days before that date expires.

Can I renew online if I have a commercial vehicle or trailer?

Most commercial vehicles and trailers can be renewed online through ct.gov/dmv. However, if your vehicle requires a special plate type or if there are outstanding violations on your account, you may need to renew in person. Try online first; if the system rejects your renewal, visit a DMV office.

What if my registration card was damaged or lost?

You can renew normally and receive a replacement card. If your card is lost or damaged before renewal is due, you can request a duplicate registration card at a DMV office for a small fee. Bring your vehicle title or current registration notice and a valid ID.
