Your credential number is the unique identifier printed on your driver's license that distinguishes your license from every other one issued in your state
The credential number is a string of numbers and sometimes letters that appears on your physical driver's license card. It is not the same as your driver's license number — they are two separate identifiers that serve different purposes. Your state's Department of Motor Vehicles (DMV) assigns this number when your license is issued, and it stays with that specific card for its entire validity period.
Think of it this way: your driver's license number is tied to you as a person and stays the same across renewals. Your credential number is tied to that particular piece of plastic. If you renew your license and receive a new card, you get a new credential number, even though your driver's license number remains the same.
Key Takeaways
- Your credential number is printed on your physical license card and changes each time you renew or replace your license.
- The credential number is different from your driver's license number, which stays with you throughout your driving record.
- Law enforcement and other officials use the credential number to verify that the specific card in your hand is valid and current.
- You may need to provide your credential number when dealing with insurance companies, rental car agencies, or law enforcement during a traffic stop.
Where to find your credential number on your license
The location of the credential number varies slightly by state, but it is always printed directly on the front or back of your license card. On most modern licenses, you will find it near the bottom of the card, often labeled as "Credential #" or "Credential Number." Some states print it on the back alongside a barcode or magnetic stripe.
If you are unsure where to look on your specific license, check your state's DMV website — they provide diagrams showing exactly where each piece of information appears on the license. The credential number is always visible without any special equipment or technology needed to read it.
Why credential numbers exist
Credential numbers serve a security and tracking purpose. Because a physical license card can be lost, stolen, or damaged and replaced multiple times during your life, the DMV needs a way to track each individual card separately from your driving record. The credential number makes it possible to identify which specific card was presented during a traffic stop, insurance claim, or age verification.
When a police officer scans your license during a traffic stop, they are checking that the credential number matches an active, valid license in the system. If your license has been reported lost or stolen, the credential number helps law enforcement know that the card is no longer valid, even if the driver's license number itself is still active.
Credential number versus driver's license number
Your driver's license number is your primary identifier and remains the same from the moment you first receive a license until you stop driving in that state. It appears on every license you hold in that state, whether you renew it five times or ten times. This number is linked to your driving record, violations, points, and insurance history.
Your credential number, by contrast, is specific to the physical card you are holding right now. Renew your license, get a replacement card, or update your address and receive a new card — you get a new credential number. The old credential number becomes inactive, but your driver's license number stays the same and your driving record continues uninterrupted.
When you need to provide your credential number
Most of the time, you will not need to provide your credential number separately. When you hand your license to a police officer, insurance agent, or rental car clerk, they can see it printed on the card itself. However, if you are reporting your license lost or stolen, you may need to give the credential number over the phone to your DMV so they can flag that specific card as invalid.
Some states' online DMV portals ask for your credential number when you log in to check your driving record or renew your license, as a way to verify that you are the person requesting the information. If you are unsure whether you need it for a specific transaction, the organization asking for it will tell you where to find it on your card.
What happens to your credential number when you renew
When you renew your driver's license, whether online, by mail, or in person at your DMV office, you receive a new physical card with a new credential number. The old credential number becomes inactive and is no longer valid. Your driver's license number, however, remains the same unless your state has changed its numbering system or you have requested a new number for privacy reasons.
This is why it is important to destroy your old license card once you receive your new one — the old credential number should not be in circulation. Most states ask you to cut up or return your expired license to prevent confusion or misuse.
Credential numbers and license replacements
If your license is damaged, lost, or stolen before it expires, you can request a replacement card from your DMV. A replacement card — even if it is issued the same day — will have a new credential number. The replacement process is usually faster and cheaper than a full renewal, but you will still receive a new card with a new credential number.
If your license is lost or stolen, report it to your DMV when ready and provide the credential number of the lost card. This flags that specific card so that if someone finds it or steals it, the credential number will not match an active license in the system.
Frequently Asked Questions
Is my credential number the same as my driver's license number?
No. Your driver's license number stays the same throughout your life in that state, but your credential number changes every time you get a new physical card — whether through renewal, replacement, or address update. The credential number is tied to the specific card, not to you as a person.
What should I do if I lose my license and need to report the credential number?
Contact your state's DMV by phone or through their website and report the license lost or stolen. Have your driver's license number ready, and provide the credential number if you can find it (it is printed on the card itself). The DMV will flag that credential number so the card cannot be used even if found.
Do I need to memorize my credential number?
No. Your credential number is printed on your license card, so you only need to know where to find it if someone asks for it. You do not need to memorize it for everyday driving or identification purposes.
Will my credential number change if I update my address?
If you update your address and receive a new physical card, yes — you will get a new credential number. However, if your state allows address updates without issuing a new card, your credential number stays the same. Check with your DMV about whether your specific update requires a new card.
Can someone use my credential number to commit fraud?
A credential number alone is not enough to commit fraud, since it is printed on the physical card and visible to anyone who sees your license. However, if your license is stolen, report it when ready so the credential number is flagged as invalid in the system. This prevents the stolen card from being used for age verification or other purposes.
