Where to find your Colorado driver license number

Your Colorado driver license number is printed on the front of your physical license card in the upper right corner. It is an eight-digit number that uniquely identifies you in Colorado's motor vehicle system. If you have your card in front of you, that is the fastest way to locate it.

If you cannot find your physical card, you have several other ways to retrieve the number. Colorado's Department of Revenue keeps records of all active licenses and can provide your number through their online portal, by phone, or in person at a local office. The method you choose depends on how quickly you need the information and what documents you have available.

Key Takeaways

  • Your Colorado driver license number is an eight-digit code printed on the front of your license card in the upper right corner.
  • You can retrieve your number online through Colorado's Department of Revenue website using your name, date of birth, and last four digits of your Social Security number.
  • Calling the Department of Revenue at 303-205-5613 will connect you to staff who can look up your number over the phone with basic identification information.
  • Visiting a local Colorado Division of Motor Vehicles office in person requires proof of identity but gives you when ready access to your license information.

Using Colorado's online license lookup tool

The Colorado Department of Revenue operates an online system where you can retrieve your driver license number without leaving home. Go to the Colorado Division of Motor Vehicles website and look for the "License Lookup" or "Driver Record" section. You will need to provide your full name, date of birth, and the last four digits of your Social Security number.

The system will display your current license number along with other basic information like your address and license class. This process typically takes less than a minute. If the system cannot find a match, double-check that you entered your name exactly as it appears on your license — middle names, hyphens, and spelling must match precisely.

Keep in mind that this tool works only for active Colorado licenses. If your license has expired or been suspended, you may still retrieve the number, but the system will flag the status. If you have never held a Colorado license, the lookup will not return results.

Calling the Department of Revenue directly

You can reach the Colorado Division of Motor Vehicles by phone at 303-205-5613. Have your full name, date of birth, and current address ready when you call. Staff will ask you to verify this information before providing your license number.

Wait times vary depending on the time of day and day of the week. Early mornings and mid-week calls typically have shorter hold times than afternoons or Fridays. The phone line is open during standard business hours, Monday through Friday. If you call outside these hours, you will reach an automated message with the option to leave a callback request.

Some callers report that providing your Social Security number over the phone speeds up the verification process, though this is optional. If you are uncomfortable sharing that information by phone, the staff can verify you using other details instead.

Visiting a Colorado DMV office in person

Every Colorado county has at least one Division of Motor Vehicles office where you can request your license number face-to-face. Bring a government-issued photo ID such as a passport, military ID, or expired Colorado license. The staff will look up your information in the system and provide your current license number on the spot.

Office locations and hours vary by county. You can find your nearest office and its hours on the Colorado Department of Revenue website by entering your county or city. Some offices accept walk-ins, while others operate by appointment only — check before you go to avoid a wasted trip.

In-person visits are useful if you need additional services at the same time, such as renewing your license or updating your address. You can often handle multiple transactions in one visit, which saves time compared to calling or using the online tool.

What to do if you cannot remember your Social Security number

If you are using the online lookup tool and do not have your Social Security number memorized, you have two options. First, check any documents that list it — your tax return, W-2 form, bank statements, or insurance paperwork all contain this number. Second, contact the Department of Revenue by phone or in person and explain that you cannot provide it; staff can verify you using other information instead.

The phone and in-person routes do not require your Social Security number at all. They rely on name, date of birth, and address verification, which are typically enough to confirm your identity in the system. This makes these methods a good backup if you are missing any piece of information the online tool requests.

Understanding your license number format

Colorado driver license numbers are always eight digits long and follow a specific format assigned by the state. The number does not encode personal information like your birth date or initials — it is straightforward a sequential identifier. Each Colorado driver has one unique number that stays the same throughout their driving history in the state.

If you renew your license, your number remains the same. If you move to Colorado from another state and get a new Colorado license, you receive a new Colorado number. The old number from your previous state is not transferred. This is why your Colorado number may be different from any license number you held elsewhere.

Frequently Asked Questions

Can I find someone else's Colorado driver license number?

No. Colorado's motor vehicle records are protected by privacy law. Only the license holder or authorized representatives (such as an attorney handling a case) can request someone else's driver license number through official channels. The online lookup tool and phone line require you to verify your own identity.

What if my license is expired — can I still look up the number?

Yes. Your license number remains in Colorado's system even after expiration. The online tool and phone line will still retrieve it, though they will note that your license is expired. You can use the expired number for any purpose that requires it, such as providing it to an employer or insurance company.

Do I need my license number to renew my Colorado license?

No. When you renew your license, the Department of Revenue looks you up by name and date of birth. You do not need to provide your current number. However, having it on hand can speed up the process if you are renewing online.

How long does it take to get a response if I request my number by mail?

Colorado does not offer a mail-based lookup service for driver license numbers. Your fastest options are the online tool (when ready), phone call (same day), or visiting an office in person (when ready). If you need written documentation of your number, you can request an official driver record from the Department of Revenue, which takes five to seven business days by mail.

What if the online lookup says my name is not found?

This usually means the system did not find an exact match. Check that you entered your name precisely as it appears on your license, including middle names, hyphens, or suffixes. If you recently moved to Colorado or changed your name, the system may not have updated yet. Call the Department of Revenue or visit an office to verify your information in person.
