Your credential number is a 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 separate number from your driver's license number. It appears on your physical license card and serves as proof that the document itself is genuine and has been properly issued by your state's Department of Motor Vehicles (DMV). When you renew your license, get a replacement card, or change your address, you receive a new credential number — even though your driver's license number stays the same.
This number matters because it ties your specific physical card to your record in the state system. If someone tries to use a fake or altered license, the credential number won't match what the DMV has on file. Law enforcement, banks, insurance companies, and other organizations that need to verify your identity use this number to confirm your license is real.
Key Takeaways
- Your credential number is printed on your driver's license card and changes each time you renew or replace your license, even though your driver's license number remains the same.
- The credential number is used by police, banks, insurance companies, and other organizations to verify that your physical license is genuine and matches state records.
- You can find your credential number in the lower right corner of your license card or by contacting your state DMV.
- When you renew your license or get a replacement card, the DMV assigns you a new credential number and updates their system automatically.
- Credential numbers vary in format by state — some use letters and numbers, others use only numbers, and the length differs depending on where you live.
Where to find your credential number on your license
The credential number is printed directly on your physical driver's license card. On most state licenses, it appears in the lower right corner or along the bottom edge of the card. The exact location and format vary by state — some states print it prominently, while others place it in smaller text.
If you cannot locate it on your card or your license is damaged, you can contact your state DMV directly. You will need to provide your name, date of birth, and driver's license number. The DMV can tell you your current credential number over the phone or through their online portal if your state offers one. Some states also print this information on renewal notices they mail to you.
How credential numbers differ from your driver's license number
Your driver's license number is assigned to you when you first get your license and stays with you for life in most states. It is the main identifier in the DMV system and appears on your license card. Your credential number, by contrast, is tied to the physical card itself, not to you as a person.
Think of it this way: your driver's license number is like your Social Security number — it identifies you. Your credential number is like a serial number on a passport — it identifies the specific document. When you renew your license every few years, your driver's license number usually stays the same, but you get a brand new credential number printed on your new card. If your card is lost, stolen, or damaged and you get a replacement, the replacement card has a different credential number than the original.
When you need to provide your credential number
Most everyday situations do not require your credential number. When you show your license to a police officer, a bank teller, or a store clerk checking your age, they are verifying your identity using your driver's license number and the information on the card itself.
You may need to provide your credential number when you are replacing a lost or stolen license, renewing your license, or dealing with a dispute about your license status. Some states ask for it when you update your address or change your name. Insurance companies sometimes request it when you file a claim or update your policy, because it helps them confirm you are the person holding the current, valid license. If you are ever asked for it and do not know where to find it, straightforward look at the lower right area of your license card or call your state DMV.
How credential numbers are assigned and updated
Your state DMV assigns a credential number when your physical license card is printed and issued. The number is generated by the DMV's system and encoded onto the card during production. Each time a new card is printed — whether because you renewed, replaced it, or updated your information — the DMV assigns a new credential number.
The credential number is linked to your record in the state system, so when someone verifies your license, they can check that the credential number on your card matches what the DMV has on file. If it does not match, it signals that the license may be counterfeit, altered, or no longer valid. This is why credential numbers are an important security feature: they make it much harder to use a fake or expired license without getting caught.
Credential number formats vary by state
There is no national standard for how credential numbers look. Some states use only numbers, others mix letters and numbers, and the length varies widely. A credential number in one state might be 8 digits long, while another state uses 12 characters with both letters and numbers. A few states do not use the term "credential number" at all — they may call it a "document number" or "card number" instead.
If you are moving to a new state or need to understand a credential number from a different state, check that state's DMV website. They will show you where the credential number appears on their license card and explain what it is used for. The format does not matter for your purposes — what matters is that you know where to find it on your own license and that you understand it is different from your driver's license number.
Credential numbers and identity verification
Organizations that verify your identity — such as banks opening accounts, insurance companies issuing policies, or law enforcement checking your license — may ask for or scan your credential number as part of their verification process. When they scan your license, they are often pulling both your driver's license number and your credential number from the card.
This dual verification makes it harder to commit identity fraud or use a fake license. If someone has stolen your license number but does not have the physical card with the matching credential number, the verification will fail. Similarly, if someone tries to use an old license card after you have renewed, the credential number on that old card will not match the current credential number in the DMV system, and the verification will flag it as invalid.
Frequently Asked Questions
Does my credential number change when I renew my license?
Yes. Every time you renew your license or get a replacement card, the DMV prints a new credential number on the new card. Your driver's license number usually stays the same, but the credential number is always new because it is tied to the physical card, not to you as a person.
What should I do if I cannot find the credential number on my license?
Check the lower right corner or bottom edge of your card first. If the number is not visible or your card is damaged, contact your state DMV by phone or through their website. Have your name, date of birth, and driver's license number ready, and they can provide your current credential number.
Can someone use my credential number to commit fraud?
A credential number alone is not enough to commit fraud because it is only valid when paired with the physical license card and your driver's license number. However, you should still protect your license and not share photos of it online, since a credential number combined with other information from your card could be misused.
Is the credential number the same as the barcode on my license?
No. The barcode on your license encodes information including your driver's license number and other data, but the credential number is a separate number printed in text form on the card. Some barcodes may include the credential number as part of their encoded data, but they are not the same thing.
Why does my old license have a different credential number than my new one?
Because credential numbers are assigned to the physical card, not to you. When you renew or replace your license, you get a new card with a new credential number. The old credential number is no longer valid once your new license is issued.
