Your credential number is a separate identifier from your license number
Your credential number is a unique code printed on your driver's license that identifies the specific document itself, not you as a person. It is different from your driver's license number — which is the main number on the front of your card. The credential number typically appears in smaller print, often on the back of the license or in a corner of the front, and serves as a way for government agencies and businesses to track and verify the physical card you are holding.
Not every state prints a credential number on its licenses. Some states use it as a security feature or administrative tool, while others do not include it at all. If your state does print one, it will be labeled clearly — often as "Credential Number," "Document Number," or "Control Number" — so you can spot it without confusion.

Where the credential number appears on your license
If your state includes a credential number, it will be printed somewhere on the physical card itself. On most licenses, it appears on the back in the lower portion, though some states place it on the front near the barcode or magnetic stripe. The exact location varies by state because each state designs its own license format and security features.
The number is usually printed in a smaller font than your main license number and will have a label next to it — such as "Credential Number," "Document Number," "Control Number," or "Reference Number." This label makes it straightforward to distinguish from other numbers on the card, such as your license number, date of birth code, or internal reference codes.
If you cannot find a credential number on your license, your state may not use one. You can confirm this by checking your state's Department of Motor Vehicles website or calling their customer service line.
Why states use credential numbers
Credential numbers serve as a security and administrative tool for state motor vehicle agencies. When you renew your license, replace a damaged one, or update your information, the credential number helps the agency track which version of your license is current and which ones have been cancelled or replaced. This prevents confusion if multiple versions of your license exist in the system.
The number also helps businesses and government agencies verify that the physical card in front of them is authentic and matches the person presenting it. Some states use credential numbers as part of their anti-fraud systems, making it harder to use an old or counterfeit license. Banks, employers, and law enforcement may reference the credential number when they need to confirm the validity of your specific card.
When you might need your credential number
You will most often need your credential number when dealing directly with your state's Department of Motor Vehicles. If you are replacing a lost or stolen license, renewing your license, or updating your address or other information, the DMV may ask for it to pull up your record and confirm which version of your license is active.
Some government agencies and financial institutions may also request it when verifying your identity, particularly if they are checking the validity of your physical license rather than just confirming your personal information. If you are explore for a job that requires a background check or security clearance, the employer or investigator might ask for your credential number to verify your license independently.
In most everyday situations — showing your license to a police officer, using it as ID at a store, or presenting it for age verification — you will not need to provide your credential number. It is primarily an administrative tool for official verification purposes.
How to find your credential number if you need it
Start by looking at the back of your driver's license, particularly in the lower half or along the edges. Look for a label that says "Credential Number," "Document Number," "Control Number," or "Reference Number," followed by a series of numbers or alphanumeric characters. The number is usually printed in smaller text than your main license number.
If you cannot locate it on the physical card, check your state's DMV website — many states provide information about where the credential number appears on their specific license design. You can also call your state's DMV customer service line and provide your license number or personal information; they can look up your credential number in their system and read it to you over the phone.
If you have lost your license and need the credential number, contact your state's DMV directly. They can retrieve it from their records using your name, date of birth, and license number.
Credential numbers versus other numbers on your license
Your driver's license contains several different numbers, and it is straightforward to confuse them. Your license number is the primary identifier — the large number on the front of your card that uniquely identifies you as a driver in your state. Your credential number identifies the specific physical card you hold, not you personally. If you renew your license and receive a new card, your license number may stay the same, but your credential number will change because it is a new document.
Your license may also display other codes, such as a barcode number, a magnetic stripe code, or an internal DMV reference number. These are different from the credential number and serve different purposes in the state's system. When an agency or business asks for your credential number specifically, they are asking for the number labeled as such on your card — not your license number or any other code.
What to do if your credential number is damaged or unreadable
If the credential number on your license is worn, faded, or otherwise unreadable, you should replace your license. A damaged license may not scan properly or may raise questions when you present it for verification. Contact your state's DMV to order a replacement card.
When you request a replacement, explain that your current license is damaged. The DMV will issue you a new card with a new credential number. You will typically need to provide your current license, proof of identity, and proof of residency, though requirements vary by state. The replacement process usually takes one to two weeks, though expedited options may be available for an additional fee.
