Your Colorado driver license number is printed on the front of your physical license, in the upper right corner
The number appears as a sequence of digits below your photograph. It is not your Social Security number, your date of birth, or any other identifier — it is a unique number assigned to you by the Colorado Department of Revenue when your license was first issued. The format is always numeric only, with no letters.
If you have a physical license in hand, you can read it directly. If you need the number but do not have your license with you, you have a few ways to find it without visiting an office in person.

How to find your number online through the Colorado Department of Revenue
The Colorado Department of Revenue operates an online portal where you can look up your own driver license information. Go to the Department of Revenue website and locate the section for driver license services. You will need to enter your Social Security number and your date of birth to verify your identity.
Once you log in, your license number will appear on the screen along with other details like your license expiration date and any restrictions or endorsements on your license. This method works whether your license is current, expired, or suspended. You do not need to create an account — you can look up the information as a one-time search.
Calling the Colorado Department of Revenue directly
If you prefer to speak with someone, you can call the Colorado Department of Revenue's driver license section. Have your Social Security number and date of birth ready when you call. The staff member will verify your identity and read your license number to you over the phone.
Wait times vary depending on the time of day and day of the week. Early morning calls, especially on weekdays, typically have shorter hold times. The Department of Revenue website lists the current phone number and hours of operation.
Visiting a Colorado driver license office in person
If you need your license number when ready and prefer face-to-face service, you can visit any Colorado driver license office. Bring a form of identification such as a passport, state ID, or birth certificate. The staff can look up your number in their system and provide it to you on the spot.
Office locations and hours are listed on the Colorado Department of Revenue website. Some offices operate by appointment only, while others accept walk-ins. Calling ahead to confirm hours and whether an appointment is needed will save you a trip.
What to do if your license number does not match your records
If you have received a document that lists a different driver license number than the one on your physical card, contact the Colorado Department of Revenue when ready. This can happen if there was an error during issuance, if your license was duplicated, or if there is a data entry mistake in their system.
The Department of Revenue can investigate the discrepancy and correct it if needed. Bring your physical license and the document showing the conflicting number when you contact them. They may ask you to visit an office in person to resolve the issue, depending on the nature of the error.
Your license number and what it is used for
Your Colorado driver license number is used to identify you in traffic stops, insurance claims, vehicle registration, and background checks. It is also used by law enforcement and the court system. The number itself does not encode personal information — it is straightforward a unique identifier assigned to your license record.
When you renew your license, your number stays the same. You keep the same number for life in Colorado, even if you move, change your address, or renew multiple times. This makes it easier for agencies and insurers to maintain consistent records about you.
Frequently Asked Questions
Is my Colorado driver license number the same as my Social Security number?
No. Your driver license number is a separate identifier created by the Colorado Department of Revenue. It is numeric only and is not derived from your Social Security number, though the Department may use your Social Security number to verify your identity when you request your license number.
What if I have had multiple Colorado licenses?
You have only one active driver license number at a time in Colorado. If you have renewed your license, you kept the same number. If you previously held a Colorado license, lost it, and later obtained a new one, you would have received a new number — but the Department of Revenue can tell you what your current number is.
Can I find my license number on my vehicle registration or insurance card?
Your driver license number may appear on your insurance card, depending on your insurance company's format. It does not appear on your vehicle registration. If your insurance card shows it, that is a quick way to find it without contacting the Department of Revenue.
Do I need my license number to renew my Colorado driver license?
No. When you renew, the Colorado Department of Revenue will look up your record using your name, date of birth, and Social Security number. You do not need to provide your license number to renew, though having it can speed up the process.
What should I do if my license number was on a license I lost or had stolen?
Report the lost or stolen license to the Colorado Department of Revenue as soon as possible. They can flag your old license number as inactive and issue you a new one. This prevents someone else from using your old number if they find or steal your physical card.
