What a credential number is and where to find it
Your credential number is a unique identifier assigned to your driver's license by your state's Department of Motor Vehicles. It is not the same as your driver's license number. The credential number tracks the specific physical card you hold — if you renew and receive a new card, you get a new credential number, but your driver's license number stays the same.
On your license card itself, the credential number typically appears in small print, often near the bottom or on the back. The exact location varies by state. Some states label it "Credential Number," while others may call it "Document Number," "Credential ID," or "Card Number." Check your state's DMV website or the back of your license for the specific label used in your state.
If you cannot locate it on your physical card, you can contact your state DMV directly by phone or through their online portal. You will need to provide your name, date of birth, and driver's license number. The DMV can tell you your credential number over the phone or through a records request.

Why the DMV asks for your credential number
The credential number serves as a way for the DMV to track the exact version of your license on file. When you renew your license, update your address, or correct information on your record, the DMV uses the credential number to pull up the right card and make sure changes are applied to the correct document.
Law enforcement and other agencies that verify your license may also reference the credential number to confirm they are looking at the current, valid version of your license. This is especially important if you have had multiple licenses issued over the years or if there have been corrections or replacements.
Some online services — such as real ID verification systems or third-party identity verification platforms — may ask for your credential number as part of their verification process. Providing it helps confirm that the license information you are submitting matches the actual card the DMV has on record.
How credential numbers differ by state
Each state's DMV formats and labels credential numbers differently. Some states use a straightforward numeric sequence, while others combine letters and numbers. The length and format have no bearing on what the number means — it is straightforward your state's way of organizing its records for that particular card.
A few states do not use the term "credential number" at all and instead refer to it as a "document number" or "card number." If you are unsure whether your state uses this identifier, check your state's DMV website or call their customer service line. They can confirm whether your state assigns credential numbers and where to find yours.
If you hold licenses from multiple states (which is not permitted, but can happen during a transition period), each license will have its own credential number. The credential number only applies to the specific state that issued it.
When you need your credential number
You will most often need your credential number when you are renewing your license online or through mail. Many state DMV websites require it as part of the renewal process to verify your identity and pull up your current record. Without it, the system may not recognize your request or may process it more slowly.
If you are correcting information on your license — such as a name change, address update, or error in your record — the DMV may ask for your credential number to may support the correction is applied to the right card. This is especially important if you have had multiple licenses or if there are similar names in the system.
Some third-party services that verify your identity or check your driving record may also request your credential number. Always verify that you are providing this information to a legitimate service before sharing it. Your credential number is not sensitive information in the way a Social Security number is, but it should still only be shared with official DMV services or verified third parties.
What to do if you cannot find your credential number
If your license is damaged, faded, or old enough that the credential number is no longer readable, contact your state DMV. You can usually reach them by phone, through their website, or by visiting a local office in person. Have your driver's license number, name, and date of birth ready.
If you have lost your license entirely, you will need to report it and request a replacement. The DMV will issue you a new card with a new credential number. During the replacement process, ask the DMV to provide your new credential number so you have it on file.
If you are filling out a form or completing an online transaction that requires your credential number and you do not have it, do not guess or leave it blank. Contact the DMV or the organization requesting it and ask them to help you locate it. Providing an incorrect number can delay processing or cause your request to be rejected.
Credential number versus other license identifiers
Your driver's license number, credential number, and any other identifiers on your card serve different purposes. Your driver's license number is your primary identifier and stays with you for life, even when you renew. Your credential number is tied to the specific card and changes with each renewal. Some states also print an issue date and expiration date, which tell you when that particular card was issued and when it expires.
When a form asks for your "license number," it is asking for your driver's license number, not your credential number. When it specifically asks for your "credential number," provide that instead. If you are unsure which one a form is requesting, read the label carefully or contact the organization for clarification.
Your Social Security number, if printed on your license, is a separate identifier used for tax and benefit purposes. Never confuse it with your credential number. Your credential number is printed on the front or back of your card in plain view, while your Social Security number may be printed in smaller text or on the back only.
Frequently Asked Questions
Does my credential number change when I renew my license?
Yes. Each time you renew your license and receive a new physical card, you receive a new credential number. Your driver's license number stays the same, but the credential number is specific to that card. If you renew online and receive your new card by mail, the credential number will be printed on the new card.
Is my credential number the same as my license number?
No. Your license number is your permanent identifier and does not change. Your credential number is assigned to the specific card you hold and changes each time you get a new card. Always check which one a form is asking for before you fill it in.
Can I look up my credential number online?
Many states allow you to view your credential number through their online DMV portal if you log in with your license number and other identifying information. Check your state's DMV website to see if this option is available. If not, you can call the DMV or visit an office in person.
What if I provide the wrong credential number?
If you provide an incorrect credential number on a renewal form or verification request, the DMV system may not recognize it and your request could be delayed or rejected. If this happens, contact the DMV to correct it. They can look up the right number using your license number and other information.
Do I need my credential number to check my driving record?
Most states allow you to check your driving record using just your license number and date of birth. Some may ask for your credential number as an additional verification step. Check your state's DMV website to see what information is required for a driving record request.
