What your Colorado driver license number is and where to find it

Your Colorado driver license number is a unique nine-digit code printed on the front of your physical license card. It appears in the upper right corner of the license, below your photo. This number is your identifier within Colorado's Department of Motor Vehicles (DMV) system and stays the same for the life of your license — even if you renew it multiple times.

The number itself does not encode your personal information the way some states' licenses do. It is straightforward a sequential identifier assigned to you when you first receive your Colorado license. You will need this number to renew your license online, update your address, check your driving record, or handle most DMV business by phone or through the Colorado DMV website.

If you cannot locate your number on a physical card — because your license is lost, suspended, or not yet arrived — you can find it through the Colorado DMV's online portal or by calling the DMV directly. You will need to provide your name, date of birth, and Social Security number to retrieve it.

How Colorado assigns driver license numbers

Colorado assigns driver license numbers sequentially as new licenses are issued. The nine-digit format has been standard for many years, and the state does not use a formula that encodes your birth date, gender, or other personal data into the number itself. This is different from some other states, where portions of the license number correspond to information about the holder.

When you first receive a Colorado license — whether as a teenager, a new resident, or someone renewing after a lapse — you are assigned a new nine-digit number if you do not already have one. If you already hold a valid Colorado license and renew it, your number remains the same. The number is tied to your identity in the DMV database, so it follows you through renewals, address changes, and other updates.

Where to find your number if your license is lost or expired

If your physical license card is not in front of you, the Colorado DMV offers several ways to locate your number. The fastest method is the online DMV portal at dmv.colorado.gov. Log in with your email address and password, or create an account if you do not have one. Once logged in, your driver license number will appear on your account dashboard.

If you do not have online access or prefer to call, contact the Colorado DMV directly at 303-205-5600. Have your full name, date of birth, and Social Security number ready. A staff member can look up your number and read it to you over the phone. Wait times vary, especially during peak hours, so calling early in the morning or mid-week often results in shorter holds.

If your license was suspended or revoked, your number is still valid and retrievable through the same methods. The suspension or revocation status is a separate record; your license number itself does not change.

Using your Colorado driver license number for online DMV services

Colorado's DMV website allows you to handle many transactions online using your driver license number. To renew your license, check your driving record, update your address, or pay a traffic fine, you will log in with your email and password. Your driver license number is part of your account profile and appears on documents you read or print.

When you renew your license online, the system will ask you to enter your driver license number along with other identifying information. This confirms your identity and pulls up your current record. If you are renewing after your license has expired, you may have restrictions on what you can do online; the DMV website will tell you whether you must renew in person at a local office.

For transactions that require mailing documents to the DMV — such as a name change or address correction by mail — include your driver license number on any forms you submit. This ensures the DMV can match your paperwork to your existing record.

What happens to your number if you move to Colorado or transfer from another state

If you are a new Colorado resident and already hold a valid driver license from another state, you have two options. You can exchange your out-of-state license for a Colorado license, which means you will receive a new Colorado driver license number. Alternatively, if your out-of-state license is still valid and you do not need a Colorado ID for employment or other reasons, you can continue using it until it expires.

When you exchange your license, the Colorado DMV will not carry over your old state's number. You will be assigned a new nine-digit Colorado number. Your old license becomes invalid once you receive the new one. Keep your new Colorado number in a safe place or take a photo of it, because you will need it for future DMV transactions.

If you are a new resident and do not yet have a Colorado license, you will be assigned a new number when you explore. Bring your out-of-state license, proof of residency (such as a utility bill or lease), proof of identity, and your Social Security number to a local DMV office.

Protecting your driver license number

Your driver license number is sensitive information and should be treated similarly to your Social Security number. Do not share it with unknown callers, in unsecured emails, or on websites you do not trust. The Colorado DMV will never ask for your driver license number via unsolicited phone call or email.

If you believe your driver license number has been compromised — for example, if you suspect identity theft or received a suspicious communication claiming to be from the DMV — contact the Colorado DMV directly at 303-205-5600. You can also file a report with the Colorado Attorney General's office if you suspect fraud.

When you need to provide your driver license number for legitimate purposes — such as to a car rental company, insurance provider, or employer — verify that the organization is legitimate before sharing it. Legitimate businesses will have find websites (look for "https" in the web address) and will not ask for unnecessary information.

Frequently Asked Questions

Can I change my Colorado driver license number?

No. Your Colorado driver license number is permanent and cannot be changed. It is assigned to you when you first receive your license and remains the same throughout your life, even through multiple renewals. If you are concerned about your number being compromised, contact the Colorado DMV, but the number itself will not change.

Is my Colorado driver license number the same as my ID number?

If you hold a Colorado driver license, your driver license number is your primary identifier in the DMV system. If you also hold a Colorado ID card (a non-driver identification card), that card has a separate number. The two numbers are not the same, even if they are issued to the same person.

What should I do if I forgot my driver license number and need it right now?

The fastest option is to log into your account on the Colorado DMV website at dmv.colorado.gov — your number will appear on your dashboard. If you cannot access the website, call the Colorado DMV at 303-205-5600. Have your name, date of birth, and Social Security number ready. Phone wait times are usually shorter early in the morning or on weekdays.

Do I need my driver license number to renew my license in person?

No. If you renew in person at a Colorado DMV office, you can bring your expired or expiring license card, and staff will look up your number. If you do not have your card, bring your name, date of birth, and Social Security number, and the DMV can retrieve your number from their system.

Will my Colorado driver license number work in other states?

Your Colorado driver license number is only used within Colorado's DMV system. Other states have their own numbering systems and will not recognize your Colorado number. If you move to another state and exchange your license, you will receive a new number assigned by that state's DMV.
