Your credential number is Connecticut's way of identifying you as a licensed driver
Connecticut's credential number is a unique identifier the state assigns to you when you receive a driver's license, permit, or ID card. It appears on your physical license and in the state's motor vehicle records. Think of it as your personal filing number in Connecticut's system — it links your name, address, driving history, violations, and license status all together in one place.
This number is different from your driver's license number itself. While your license number changes if you renew or replace your card, your credential number stays the same throughout your driving life in Connecticut. It's the permanent reference point that law enforcement, insurance companies, and the DMV use to look up your record.
You don't need to memorize it or explore for it separately. Connecticut assigns it automatically when you first get your permit or license. It will be printed on your card, and you can also find it in your DMV records online or by calling the Connecticut Department of Motor Vehicles.

- Connecticut automatically assigns your credential number when you first receive a permit or license; you do not request it separately.

- You can find your credential number on your physical license card or by checking your DMV records online.
Where your credential number appears
Your credential number is printed directly on your Connecticut driver's license or ID card. The exact location depends on which version of the card you hold, but it is always visible on the front or back of the physical card alongside your name, address, and license number.
If you don't have your card in front of you, you can look up your credential number through the Connecticut DMV's online services. You'll need to log in with your driver's license number and other identifying information. You can also call the Connecticut Department of Motor Vehicles directly and provide your name and date of birth to have them read it to you over the phone.
Why insurance companies and police ask for it
When you get a car insurance quote or file a claim, the insurance company uses your credential number to pull your complete driving record from Connecticut's system. This includes any accidents, traffic violations, suspensions, or other incidents tied to your license. The credential number ensures they're looking at the right person's history, not someone with a similar name.
Law enforcement also uses your credential number when they run your license during a traffic stop. It connects them when ready to your current license status, any active suspensions or restrictions, and your driving history. This is why having a valid, current license is important — your credential number is how the officer verifies that status in real time.
The difference between credential number and license number
Your license number is printed on your physical card and changes every time you renew your license or get a replacement card. If you renew your license every five years, you'll get a new license number each time. If your card is lost or damaged and you order a replacement, you'll receive a new license number on the replacement card.
Your credential number, by contrast, never changes. It's the state's internal reference that stays constant in their system. This is why the credential number is more reliable for looking up your permanent record — it doesn't shift when you renew or replace your card.
In practice, most interactions use your license number because it's the one visible on your card. But behind the scenes, Connecticut's system uses your credential number to make sure all your records stay linked to you, no matter how many times you renew.
How credential numbers work with your driving record
Everything in your Connecticut driving record — every ticket, every accident, every suspension — is tied to your credential number, not your license number. This means your record follows you even if your license number changes at renewal. An accident you had five years ago will still show up on your record under your credential number, even though your current license number is different.
This is important to understand because your driving record affects your insurance rates, your ability to renew your license, and whether you face any restrictions or suspensions. The credential number is what keeps all of that history connected to you across the years.
What to do if you lose your license or need a replacement
If your physical license card is lost, stolen, or damaged, you can order a replacement from the Connecticut DMV. Your replacement card will have a new license number, but your credential number will remain the same. You don't need to do anything special to keep your credential number — it's automatic.
When you renew your license at the end of its validity period, the same thing happens: you get a new license number on your new card, but your credential number stays the same. Your driving record, insurance history, and all other state records continue to be linked to that same credential number.
Frequently Asked Questions
Can I look up my credential number online?
Yes. Log into the Connecticut DMV's online portal with your driver's license number and other identifying information. Your credential number will be displayed in your account. You can also call the Connecticut Department of Motor Vehicles and provide your name and date of birth to have them tell you your credential number over the phone.
Does my credential number change if I move to a different state?
No. Your Connecticut credential number is specific to Connecticut and stays with your Connecticut license. If you move and get a license in a new state, that state will assign you a new credential number for their system. Your old Connecticut credential number remains in Connecticut's records.
What if I have the same name as someone else — could we get mixed up?
The credential number system is designed to prevent this. Even if two people share the same name, they each have a unique credential number tied to their date of birth, address, and other identifying details. Law enforcement and insurance companies use the credential number specifically to make sure they're looking at the right person's record.
Is my credential number the same as my Social Security number?
No. Your credential number is a separate identifier created by Connecticut's DMV system. It is not your Social Security number, and the two are not linked in the same way. Your credential number is used only for driving and vehicle-related records.
Do I need to memorize my credential number?
You don't need to memorize it for everyday driving. However, it's helpful to know where to find it if an insurance company, employer, or other organization asks for it. Keep a copy of your license information in a safe place, or know how to look it up through the Connecticut DMV online.
