Where the number appears on your card

Your Colorado driver's license number is printed in the upper right corner of the front of your card, positioned just below your photograph. It is an eight-digit number displayed in a clear, straightforward-to-read font. The same number also appears on the back of the license in smaller print, located in the lower left area of the card.

The front placement makes it straightforward to find when you need it quickly — at a traffic stop, when renting a car, or when filling out a form. The back copy serves as a backup reference if the front becomes difficult to read or if you need to verify the number a second time.

The number sits apart from other information on your card, so it should not be confused with expiration dates, issue dates, or restriction codes that appear elsewhere on the license.

Key Takeaways

  • Your Colorado driver's license number is an eight-digit number located in the upper right corner of the front of your card, just below your photo.
  • The same number also appears on the back of the license in smaller print in the lower left area.
  • This number is different from your Social Security number and is unique to your Colorado license only.
  • You will need this number when you renew your license, report it lost or stolen, or provide it to insurance companies and rental agencies.
  • Your license number remains the same for your entire life in Colorado, even when you renew your card.

How the number is formatted

Colorado driver's license numbers are always eight digits long and contain only numbers — no letters or special characters. The format is straightforward and consistent across all Colorado licenses issued in recent years. When you see your number on the card, it will appear as a straightforward sequence like 12345678.

When you write down or type your license number, use all eight digits exactly as they appear on your card. Some forms may ask you to include dashes or spaces between the digits for readability, but the actual number itself contains no punctuation. If a form provides spaces or dashes, fill them in as the form directs, but the core number remains the same eight digits.

Do not add leading zeros or alter the number in any way. The number as printed on your card is the correct version to use for all purposes.

What this number is used for

Your driver's license number is your primary identifier for driving-related transactions in Colorado. You will provide it when you renew your license, report your license lost or stolen, or request a replacement card. Law enforcement officers use this number during traffic stops to pull up your driving record and verify your identity.

Insurance companies require your driver's license number when you purchase or renew an auto insurance policy. They use it to check your driving history and calculate your rates. Car rental agencies also ask for this number before they hand over a vehicle, and they use it to verify your identity and driving status.

Banks and other businesses sometimes ask for your driver's license number as a secondary form of identification when you open an account or conduct certain transactions. However, they may also accept your Social Security number or passport instead, so you can ask what forms of ID they will take.

Difference between your license number and other identifiers

Your Colorado driver's license number is separate from your Social Security number. The license number is issued by the Colorado Department of Revenue, Division of Motor Vehicles, and applies only to your driving privileges in Colorado. Your Social Security number is a federal identifier managed by the Social Security Administration and is used for tax, employment, and financial purposes across all states.

If you move to another state, your new state's driver's license will have a completely different number. Colorado's number does not transfer or carry over — it remains tied to your Colorado license only. If you later move back to Colorado and need a new license, you will receive a new number rather than getting your old one back.

Your license number is also different from your license plate number (if you own a vehicle) and your vehicle identification number (VIN). Each of these serves a different purpose in the Colorado system.

What to do if you cannot find your number

If your license is damaged, faded, or you straightforward cannot locate the number, you can contact the Colorado Department of Revenue, Division of Motor Vehicles. They can provide your license number over the phone or through their online portal if you have set up an account on the DMV website.

You will need to provide identifying information such as your full name, date of birth, and current address to confirm who you are. Having your Social Security number handy will speed up the process. The DMV staff can look up your record in their system and read your number to you.

If your physical license is lost or stolen, you can still obtain your number this way before you order a replacement card. This is useful if you need the number for insurance or rental purposes while you wait for your new card to arrive.

What happens to your number when you renew

Your Colorado driver's license number stays the same throughout your life, even when you renew your license. The number is tied to your identity in the Colorado system, not to the physical card itself. When you renew your license — whether online, by mail, or in person — you keep the same eight-digit number.

The physical card will be replaced with a new one that has a new expiration date and an updated photo, but the license number printed on it will be identical to the number on your old card. This consistency makes it easier for insurance companies, employers, and government agencies to maintain records about you over time.

Frequently Asked Questions

Can I use my license number instead of my Social Security number?

Sometimes, but not always. Your driver's license number works for driving-related matters and some business transactions, but banks, employers, and government agencies typically require your Social Security number for financial and tax purposes. Ask what form of identification a business needs before you assume one will work.

Where do I find my license number if I only have my old expired license?

Your expired license still shows your number in the same location — upper right corner on the front. The number does not change when your license expires, so the number on an old license is still your current Colorado driver's license number.

What should I do if my license number appears on someone else's license?

Contact the Colorado Department of Revenue when ready. This is rare but indicates a serious error in the system. Bring your license and any documentation you have, and ask them to investigate and correct the records.

Does my license number change if I get a REAL ID compliant license?

No. If you upgrade to a REAL ID compliant Colorado license, your eight-digit license number remains the same. The REAL ID designation is a security feature on the card itself, but your underlying license number does not change.
