Your credential number is the unique identifier printed on your Connecticut driver's license or ID card

Your Connecticut credential number is a nine-digit code that appears on the front of your driver's license or state ID card. It is not the same as your driver's license number — it is a separate identifier that Connecticut uses to track your driving record and vehicle registrations. You will need this number when you renew your license, register a vehicle, or handle other DMV business.

The credential number stays with you throughout your driving life in Connecticut, even if your license number changes. It links all your driving records together in the state system, so DMV staff can pull up your complete history no matter which office you visit or how many times you have renewed.

Key Takeaways

  • Your credential number is a nine-digit code printed on the front of your Connecticut driver's license or ID card, separate from your license number.
  • The credential number remains the same throughout your life in Connecticut, even when you renew your license or change your address.
  • You will need your credential number when renewing your license, registering a vehicle, or conducting other business with the Connecticut DMV.
  • If you cannot locate your credential number on your card, you can contact the Connecticut DMV directly or check your renewal paperwork.

Where to find your credential number on your license

On a Connecticut driver's license or ID card, the credential number appears on the front of the card. Look for a nine-digit number — it is typically positioned in the upper right area or along the bottom edge of the card, depending on when your license was issued. The exact placement has shifted slightly over the years as Connecticut updated its card design, but it is always printed clearly on the front.

If you have a physical card in your wallet, this is the fastest way to locate it. The number will be printed in black text and is straightforward to spot once you know what you are looking for. Write it down or take a photo if you need to reference it later.

When you will need your credential number

The Connecticut DMV asks for your credential number in several common situations. When you renew your driver's license — whether in person, by mail, or online — you will be asked to provide it. If you register a vehicle or renew your vehicle registration, the DMV will request this number to link your driving record to your vehicle.

You may also need it if you are updating your address, replacing a lost or damaged license, or requesting a copy of your driving record. Some insurance companies ask for it when you quote or purchase a policy, since it helps them access your official driving history. Having it ready before you contact the DMV or visit an office saves time.

What happens if you cannot find your credential number

If your license card is lost, damaged, or you straightforward cannot locate the number, contact the Connecticut DMV directly. You can call the DMV customer service line or visit a local DMV office in person. Staff can look up your credential number using your name, date of birth, and Social Security number — they have access to your complete record in the state system.

If you are in the middle of a renewal or registration process and need the number when ready, the DMV can provide it over the phone. You can also check any renewal notices or correspondence you have received from the DMV — your credential number is often printed on those documents as well.

How your credential number differs from your license number

Connecticut uses two separate numbers on your driver's license, and it is important to understand the difference. Your license number is the primary identifier on your card and changes each time you renew your license. Your credential number is a permanent identifier that stays the same for life.

Think of it this way: your license number is like the version of your license, while your credential number is like your permanent file. When you renew, you get a new license number, but the credential number in the DMV system remains unchanged. This is why the DMV uses the credential number to track your complete driving history across multiple licenses and renewals.

Keeping your credential number safe

Your credential number is not as sensitive as your Social Security number, but it is still part of your official identity in Connecticut. Treat it the way you would treat your license number — do not share it unnecessarily, and be cautious about providing it to unfamiliar websites or callers claiming to represent the DMV.

The legitimate Connecticut DMV will never call you asking for your credential number unprompted. If someone contacts you claiming to be from the DMV and asks for this information, verify the call by hanging up and dialing the official DMV number yourself. Keep your physical license in a safe place, and if it is lost or stolen, report it to the DMV right away.
