What the credential number is and where to find it
The credential number on your driver's license is a unique identifier assigned by your state's Department of Motor Vehicles (DMV). It is not the same as your driver's license number. On most licenses, the credential number appears as a separate field, often labeled "Credential Number," "Control Number," or "Document Number" depending on your state.
The credential number typically sits near the bottom of the front or back of your license, sometimes in smaller print. It is usually a combination of letters and numbers, often between 6 and 12 characters long. This number tracks the specific physical card itself — if you renew your license and receive a new card, you get a new credential number, even though your driver's license number stays the same.
Not all states display the credential number in the same location or format. Some states print it prominently; others tuck it into a corner. If you cannot locate it on your card, check your state's DMV website for a diagram showing where each field appears on your particular license design.
Key Takeaways
- The credential number is a unique code for the physical license card itself, separate from your driver's license number.
- It typically appears as a 6- to 12-character combination of letters and numbers, usually near the bottom of the card.
- Each time you renew your license and receive a new card, you receive a new credential number.
- The location and format vary by state, so check your state DMV's website if you cannot find it on your card.
- You may need the credential number when verifying your identity online, updating your address, or dealing with certain government agencies.
Why you might need the credential number
Government agencies and some private organizations request the credential number to verify that you hold a valid, current driver's license. It serves as proof that the physical card in your hand is genuine and currently active. When you update your address with the DMV online, for example, the system may ask for the credential number to confirm you are the cardholder.
Law enforcement and court systems sometimes use the credential number during traffic stops or legal proceedings to pull up your exact license record. Banks and financial institutions may also ask for it as part of identity verification, especially when you are opening an account or explore for credit. The credential number is harder to guess or forge than your driver's license number alone, which is why it adds a layer of security to the verification process.
How the credential number differs from your driver's license number
Your driver's license number is your permanent identifier within your state's DMV system. It stays the same for your entire driving life, even if you move to a different state or renew your license multiple times. The credential number, by contrast, is tied to the physical card. When you renew your license — whether because it expired, you changed your address, or you got a replacement — you receive a new credential number on the new card.
Think of it this way: your driver's license number is like your Social Security number (it follows you), while the credential number is like a serial number on a specific passport (it changes when you get a new passport). Both appear on your license, but they serve different purposes in the DMV's record-keeping system.
Where credential numbers appear on different state licenses
Most states print the credential number on the front of the license, often in the lower right corner or along the bottom edge. Some states place it on the back, sometimes near the barcode or magnetic stripe. A few states include it in multiple locations for redundancy.
The label itself varies: you might see "Credential Number," "Control Number," "Document Number," "Sequence Number," or "Card Number." If your state's license design has changed recently, the credential number may have moved to a new location. Checking your state's DMV website for a current license sample will show you exactly where to look on your specific card.
What to do if you cannot find your credential number
Start by examining both sides of your license carefully under good lighting. The credential number is usually in smaller print than your name or license number, so it is straightforward to overlook. If you still cannot locate it, visit your state's DMV website and look for a diagram or guide showing the layout of your current license design.
If you need the credential number for an official purpose — such as renewing your license online or verifying your identity with a government agency — you can contact your state's DMV directly. Most DMVs can look up your credential number using your driver's license number and date of birth. You can usually reach them by phone, through their website's chat feature, or by visiting a local office in person.
Credential numbers and online identity verification
When you renew your driver's license or update your information through your state's DMV website, the system often asks for your credential number as a security step. This prevents someone else from accessing your account using only your license number and basic personal information. The credential number acts as a second factor of verification, similar to a PIN or security code.
Some states have also begun using credential numbers in mobile driver's license apps, which allow you to display a digital version of your license on your phone. The credential number on the digital version matches the one on your physical card, ensuring consistency across both formats.
Frequently Asked Questions
Is the credential number the same as the driver's license number?
No. Your driver's license number is permanent and stays the same throughout your life. The credential number is tied to the physical card and changes each time you renew your license or get a replacement card. Both numbers appear on your license, but they serve different purposes.
What happens to my credential number when I renew my license?
You receive a new credential number on your new license card. Your driver's license number remains the same. The DMV's system tracks both numbers so it knows which credential number belongs to your current, active license.
Can I look up my credential number online?
Most state DMV websites do not display your credential number in your online account. You can usually find it by looking at your physical license card. If you need it urgently and cannot locate it, contact your state's DMV by phone or visit a local office — they can provide it using your license number and date of birth.
Do I need to memorize my credential number?
No. You only need the credential number when a specific organization requests it. Keep your physical license in a safe place so you can reference it when needed. If you are asked for the credential number online, you can look it up on your card before entering it.
What should I do if my credential number is damaged or unreadable?
If the credential number on your license is worn, faded, or damaged, you can request a replacement card from your state's DMV. This will give you a new credential number. Contact your DMV to find out whether you can order a replacement online or if you need to visit an office in person.
