Connecticut lets you register your vehicle online through its DMV portal, but only for renewals and certain changes to existing registrations
The Connecticut DMV's online registration system is called ConneCT DMV Online Services. You can use it to renew a registration that is about to expire, add or remove a vehicle from your registration, or update information like your address. You cannot use it for a first-time registration of a new vehicle — that still requires an in-person visit or mail submission with original documents.
To use the online system, you need your current registration card, your vehicle identification number (VIN), and a valid Connecticut driver's license or ID. The process takes about 10 minutes, and you pay by credit or debit card. Your new registration is mailed to you within one to two weeks.
Key Takeaways
- Connecticut's online registration system works only for renewals and updates to existing registrations, not for registering a vehicle for the first time.
- You will need your current registration card, your VIN, and a valid Connecticut ID to log in and complete the transaction online.
- The Connecticut DMV website is ct.gov/dmv, and the online services portal is accessed from the main DMV page under "Online Services."
- After you submit your renewal online, your new registration card arrives by mail in one to two weeks, and you can drive legally during that time with your old card.
- If your registration has already expired or you are registering a vehicle for the first time, you must visit a DMV office or submit documents by mail.
What You Need Before You Start
Gather these items before you log into ConneCT DMV Online Services. You will not be able to complete the transaction without them. Your current registration card is the most important — it contains your registration number and vehicle information that the system uses to pull up your account.
You also need your vehicle's VIN, which appears on your registration card, your insurance card, and your vehicle's dashboard. Your valid Connecticut driver's license or state ID is required to verify your identity. If you are renewing a registration for a vehicle registered to someone else (such as a family member), you will need that person's permission and their ID information.
Have your payment method ready — the DMV accepts Visa, Mastercard, American Express, and Discover. The renewal fee varies depending on your vehicle type and weight, but most passenger cars cost between $100 and $150 for a two-year renewal.
How to Access the Online Registration System
Go to ct.gov/dmv and look for the "Online Services" link on the homepage. Click it, and you will be taken to the ConneCT DMV Online Services portal. From there, select "Vehicle Registration Renewal" or the option that matches what you need to do — renew, update an address, add a vehicle, or remove a vehicle.
You will be asked to enter your registration number and the last four digits of your VIN. The system will pull up your current registration. Review all the information carefully — make sure your address, vehicle details, and owner information are correct. If anything is wrong, you can make changes before you pay.
Once you confirm the information is correct, you will enter your payment details. The system will process your payment when ready and give you a confirmation number. Save or print this number — you will need it if you have questions about your renewal.
When You Cannot Use the Online System
If your registration has already expired, you cannot renew it online. You must visit a DMV office in person or submit your renewal by mail with the required documents. An expired registration means your vehicle is not legally registered, so do not drive it until you have completed the renewal process.
First-time registrations also require an in-person visit or mail submission. This includes registering a newly purchased vehicle, a vehicle you are bringing into Connecticut from another state, or a vehicle that has never been registered before. You will need the vehicle's title, proof of insurance, and a completed process form.
If you need to change your vehicle's title (such as adding or removing an owner's name), that transaction also cannot be done online. Title changes require documents signed by all owners and must be processed at a DMV office or by mail.
What Happens After You Submit Your Renewal Online
After you complete your online renewal, the Connecticut DMV mails your new registration card to the address on file. This usually takes one to two weeks. During this time, you can legally drive your vehicle using your old registration card — you do not need to wait for the new one to arrive.
If you do not receive your new registration card within three weeks, contact the DMV using the phone number on ct.gov/dmv. Have your confirmation number ready. The DMV can check the status of your renewal and remail the card if it was lost.
Your new registration is valid for two years from the date you renew it. The DMV will send you a renewal notice by mail about 60 days before your registration expires, reminding you to renew again.
Updating Your Address or Vehicle Information Online
If you have moved or need to update other information on your registration, you can do this through the same online portal. Select "Update Registration Information" instead of "Renewal," and log in with your registration number and VIN. The system will show you what information is currently on file.
You can change your mailing address, your email address, or add notes about the vehicle. Some changes, like updating the vehicle's color or adding safety equipment, can be done online. Other changes, like removing a lien or changing the vehicle's title, still require an in-person visit or mail submission.
If you are not sure whether your change can be done online, start the process and the system will tell you. If it cannot process your request, you will be directed to the correct method — either visiting a DMV office or mailing in forms.
If You Have Problems Logging In
If you forget your registration number, you can look it up on your registration card — it is printed at the top. If you have lost your registration card and do not have the number, you will need to visit a DMV office or call the DMV to get it. The phone number is on ct.gov/dmv.
If the system says your registration number or VIN is not found, double-check that you have entered them correctly. Registration numbers and VINs are case-sensitive in some systems. If you have recently moved or changed your name, there may be a delay before the system recognizes the change — wait a few days and try again.
If you continue to have trouble, you can renew by mail or visit a DMV office. The mail-in option takes longer but does not require you to log into the online system.
Frequently Asked Questions
Can I renew my registration online if it has already expired?
No. Once your registration expires, you must renew in person at a DMV office or by mail. You cannot drive the vehicle legally while it is expired, even if you are in the process of renewing. Visit ct.gov/dmv to find a DMV office near you or to request a mail-in renewal form.
Do I need to print anything before I start the online renewal?
No. You do not need to print anything beforehand. The system will give you a confirmation number at the end, which you should save or write down. You can print the confirmation page if you want a record, but it is not required.
What if I registered my vehicle in another state and just moved to Connecticut?
You cannot renew online if your vehicle is registered in another state. You must register it in Connecticut first, which requires an in-person visit to a DMV office with your out-of-state registration, title, proof of insurance, and a completed process form.
Can I renew someone else's vehicle registration online if I have their permission?
You can if you have their registration card and their VIN, but the system will ask for their driver's license or ID number to verify their identity. It is easier if the registered owner renews it themselves, but you can complete the transaction on their behalf if you have this information.
How do I know if my online renewal was successful?
The system will display a confirmation number and a confirmation page at the end of the transaction. You will also receive a confirmation email if you provided an email address. Your new registration card will arrive by mail within one to two weeks. If you do not receive it after three weeks, contact the DMV with your confirmation number.
