Your driver's license number appears in three places on your physical card

Your Colorado driver's license number is printed on the front of your card in the upper right corner, below your photograph. It is a seven-digit number that starts with a number between 1 and 9. The same number also appears on the back of your card, printed smaller, in the upper left area. If you have your physical card in front of you right now, that seven-digit sequence is what you need.

If you cannot locate your card or it is damaged, you can also find your number through the Colorado Department of Revenue's online system. You will need to log into your account using your Social Security number, date of birth, and the last four digits of your Social Security number as verification. The system will display your current license number and its expiration date.

Key Takeaways

  • Your Colorado driver's license number is a seven-digit code printed on the front of your card in the upper right corner below your photo.
  • The same number appears on the back of your card in smaller print in the upper left area.
  • You can view your license number online through the Colorado Department of Revenue website if you cannot find your physical card.
  • Your license number is different from your Social Security number and is specific to your Colorado driver's license only.

How to access your number online through the Colorado Department of Revenue

Go to the Colorado Department of Revenue's driver's license portal at dmv.colorado.gov. Look for the option labeled "Check Your Driver's License Status" or a similar link on the homepage. You will be asked to create an account or log in if you already have one.

To create an account, you will need your Social Security number, date of birth, and the last four digits of your Social Security number. Once you log in, the system will display your current license information, including your seven-digit license number, expiration date, and any restrictions or endorsements on your license. This information is the same as what appears on your physical card.

What to do if your card is lost or damaged

If your physical card is lost, stolen, or too damaged to read, you have two options to get your license number. The first is to use the online system described above—this works even if you do not have your card in hand. The second is to contact the Colorado Department of Revenue directly by phone at 303-205-5613 during business hours. Have your Social Security number and date of birth ready when you call.

If your card is damaged but still readable, you can request a replacement card by mail or in person at any Colorado Division of Motor Vehicles office. The replacement process takes about two weeks by mail. Your license number will not change when you receive a replacement card—it remains the same for the life of your license unless you renew it.

Understanding the format of your Colorado license number

Colorado license numbers are always seven digits long and always begin with a number from 1 to 9. The number is assigned to you when you first receive your license and stays with you through renewals. It is not based on your name or Social Security number, so you cannot calculate it yourself—it must be looked up or read from your card.

This number is different from your license plate number (which is on your vehicle), your vehicle identification number or VIN (which is on your car's title and door frame), and your Social Security number. When you need to provide your driver's license number for a form or verification, use only this seven-digit code from your card.

Where you might need your Colorado driver's license number

You will be asked for your driver's license number when you rent a vehicle, open a bank account, explore for certain jobs, or verify your identity online. Insurance companies also ask for it when you get a quote or file a claim. Some government agencies and financial institutions may request it as part of identity verification.

Keep in mind that your license number is not the same as your license plate number. If a form asks for your "driver's license number," it is asking for the seven-digit code on your card, not anything related to your vehicle. If you are unsure which number a form is asking for, contact the organization directly before submitting.

Frequently Asked Questions

Is my Colorado driver's license number the same as my Social Security number?

No. Your driver's license number is a separate seven-digit code assigned by the Colorado Department of Revenue. Your Social Security number is a nine-digit federal identifier. They are completely different numbers and should never be confused.

What if I just renewed my license—did my number change?

No. Your license number stays the same when you renew. It only changes if you get a replacement card due to loss, theft, or damage in some cases, but typically it remains constant throughout your driving life in Colorado.

Can I find my license number on my vehicle registration or insurance card?

Your vehicle registration and insurance card do not display your driver's license number. They show your vehicle information instead. You must look at your physical driver's license card or check the Colorado Department of Revenue online system to find your license number.

What should I do if I cannot remember my password for the Colorado DMV website?

The Colorado Department of Revenue website has a "Forgot Password" link on the login page. Click it and follow the prompts to reset your password using your email address or phone number. If you continue to have trouble, call 303-205-5613 for information.
