Your credential number is a unique identifier the DMV assigns to your driver's license
The credential number is a separate number from your driver's license number. It appears on your license document itself and serves as an internal tracking code for the Department of Motor Vehicles. Think of it as the DMV's own filing system — it helps them organize and retrieve your specific license record in their database.
You will see this number printed on your physical license card, usually in small text. The exact location and format varies by state, but it is always distinct from the main license number that appears prominently on the front. Some states call it a "document number" or "credential ID" instead, but they all serve the same purpose.
The credential number matters when you need to replace a lost or damaged license, renew your license, or when the DMV needs to pull up your record for any reason. It is also useful if you are dealing with a specific license-related issue and need to reference your exact document in the DMV's system.

Where to find your credential number on your license
The credential number is printed directly on your driver's license card. On most licenses, it appears in the lower portion of the card or along the edges, often in smaller font than your main license number. Look for text that says "Credential Number," "Document Number," "Credential ID," or similar language — the label itself tells you what you are looking at.
If you cannot locate it on your physical card, check your license renewal notice or any official DMV documents you have received. These documents often include your credential number for reference. You can also contact your state's DMV directly and provide your name and date of birth, and they will give you the number over the phone or through their online portal.
Why the DMV uses credential numbers
Driver's licenses are physical documents that can be replaced, renewed, or reissued multiple times over your lifetime. Each time you get a new card — whether because yours expired, was damaged, or you changed your address — the DMV issues a new document. The credential number stays the same across all these replacements, creating a continuous thread through your license history.
This system helps the DMV distinguish between your current license and old ones you may have held. It also prevents confusion when multiple people in the system have similar names or birth dates. The credential number is the DMV's way of saying "this is the specific card we issued to you on this specific date," which matters for record-keeping and verification purposes.
When you will need to provide your credential number
You may need your credential number when you contact the DMV about a specific license issue — for example, if you are reporting a lost or stolen license, requesting a replacement card, or following up on a renewal. Having the number ready speeds up the process because it lets the DMV pull your exact record without having to search through multiple documents or renewals.
Some third-party services that verify your identity or check your driving record may also ask for your credential number. Insurance companies, for instance, sometimes request it when you are getting a quote or filing a claim. Having it handy saves time and reduces the chance of pulling the wrong record.
You do not need to memorize it or carry it separately — it is printed right on your license. But if you are going to contact the DMV or know you will need it soon, taking a photo of your license or writing down the number beforehand can be helpful.
How credential numbers differ by state
Every state's DMV uses some form of credential or document number, but the exact format, length, and placement vary. Some states use a straightforward sequential number, while others use a code that encodes information like the year your license was issued. The number of digits also differs — some states use six digits, others use eight or more.
The terminology also changes. Your state might call it a "credential number," "document number," "license document ID," or something similar. Regardless of what your state calls it or how it is formatted, the function is the same: it is your DMV's internal identifier for that specific license card.
If you move to a new state and get a new license, your credential number will change because it is issued by that state's DMV. Your old credential number from your previous state has no meaning in your new state's system.
Credential number versus license number
Your driver's license number and your credential number are two different things, and it is important not to confuse them. Your license number is the main identifier printed prominently on the front of your card — it is what most people think of as "your license number" and what you provide when asked for your license information.
Your credential number is a secondary identifier used internally by the DMV. It is smaller, less prominent, and serves a different purpose in the DMV's filing system. When you renew your license, your license number may change, but your credential number will also change because you are receiving a new physical document. Both numbers are tied to that specific card.
If someone asks for your "license number," they almost always mean your main driver's license number, not your credential number. Only provide your credential number if specifically asked for it or if you are dealing directly with the DMV.
What to do if you cannot find your credential number
If your license is damaged or worn and the credential number is no longer legible, contact your state's DMV to request a replacement card. You will not be penalized for this — wear and tear on a license is normal, and the DMV replaces cards regularly for this reason.
If you need your credential number for a specific purpose right now and cannot read it on your card, call your state's DMV or visit their website. Most states have online portals where you can log in with your name, date of birth, and license number to view your credential number. Some states also allow you to request this information by mail or in person at a DMV office.
Frequently Asked Questions
Is my credential number the same as my license number?
No. Your license number is the main identifier on your card, while your credential number is a separate code the DMV uses internally. They appear in different locations on your license and serve different purposes in the DMV's system.
Do I need to memorize my credential number?
No. It is printed on your license, so you can look it up whenever you need it. You only need to provide it if the DMV or another organization specifically asks for it.
What happens to my credential number when I renew my license?
Your credential number changes when you renew because you receive a new physical license card. Each card the DMV issues gets its own credential number, even if it is being issued to the same person.
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 personal 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.
Why does the DMV need a credential number if they already have my license number?
The credential number helps the DMV track the specific physical document they issued to you. Since licenses are replaced and renewed throughout your life, the credential number creates a clear record of which card is current and which are old, preventing confusion in their system.
