A credential number is a unique identifier printed on your driver's license that the DMV uses to track your specific license record in their system.
It is not the same as your driver's license number. Your license number is the main number on the front of your card — the one you use to prove identity. Your credential number is a separate code, usually found on the back of your license or in your DMV record, that links to the exact version of your license that was issued on a particular date.
Think of it this way: your license number stays the same for years, but every time you renew, get a duplicate, or update your address, the DMV creates a new credential. The credential number tracks which specific card or record you are talking about. If you have renewed your license three times, you have three different credential numbers — one for each issuance.
Key Takeaways
- Your credential number is a separate code from your main license number and identifies a specific version of your license issued on a particular date.
- The credential number appears on the back of your physical license card or in your online DMV account, depending on your state.
- You need your credential number when requesting official records, reporting a lost or stolen license, or resolving disputes with the DMV.
- Each time you renew or receive a duplicate license, you get a new credential number; the old one remains tied to that earlier version.
Where to Find Your Credential Number
The location varies by state. In most states, the credential number is printed on the back of your physical license card, usually near the bottom or in a corner. Some states place it on the front. If you cannot find it on the card itself, log into your state's DMV online portal — your credential number will appear in your account details or in the section showing your current license information.
If you have lost your license or do not have it with you, call your state DMV directly. They can look up your credential number using your name, date of birth, and license number. You do not need the credential number to drive — you only need it when dealing with the DMV or requesting official documents.
Why the DMV Uses Credential Numbers
The credential number exists because the DMV issues many versions of the same license over time. When you renew every four or eight years, you get a new card with a new credential number. When you request a duplicate because your card was damaged, that duplicate has its own credential number. When you update your address without renewing, some states issue a new card with a new credential number.
Without credential numbers, the DMV would have no way to distinguish between your 2019 license and your 2023 license in their system. If a question arose about which version of your license was valid, or if there was a discrepancy in your record, the credential number tells them exactly which issuance you are referring to. It also helps prevent fraud — a credential number is harder to forge than a license number alone.
When You Need to Provide Your Credential Number
You will need your credential number in these situations:
- Requesting an official copy of your license record from the DMV
- Reporting your license lost or stolen
- Disputing an error on your record or license
- Replacing a damaged or worn card
- Responding to a DMV inquiry or notice
- Some states require it when renewing online or by mail
In most everyday situations — showing your license at a traffic stop, using it for age verification, or presenting it as ID — you do not need the credential number. Police and businesses only look at your main license number and the information on the front of the card.
How Credential Numbers Change
Your credential number changes each time the DMV issues you a new physical card. This happens during renewal, when you request a duplicate, when you change your address and your state issues a new card, or when you update your license class or endorsements. The old credential number does not disappear — it remains in the DMV system tied to that earlier version of your license, but it is no longer active.
If you renew your license online or by mail in a state that does not issue a new card, your credential number may stay the same. Some states only issue new cards every other renewal cycle. Check your state's renewal rules to know whether you will receive a new card and therefore a new credential number.
Credential Numbers and License Verification
When an employer, insurance company, or government agency requests to verify your license, they may ask for both your license number and your credential number. The credential number helps them confirm they are looking at the current, valid version of your license. This is especially important for jobs that require a clean driving record check or for insurance purposes, where the company needs to know the exact date your license was issued or renewed.
If you are unsure whether to provide your credential number to a third party, contact your state DMV first. They can tell you whether the request is legitimate and what information is safe to share.
Common Mistakes and Confusion
The most common mistake is confusing your credential number with your license number. Your license number is the main identifier — it appears on the front of your card and stays the same throughout your life (or for the duration of that license class). Your credential number is secondary and changes with each new card issuance.
Another mistake is assuming you need your credential number for routine tasks. You do not. You only need it when the DMV specifically asks for it or when you are requesting official records. If a form asks for your "license number," provide your main license number, not your credential number, unless the form specifically says "credential number."
Frequently Asked Questions

What happens to my old credential number when I renew?
Your old credential number remains in the DMV system tied to that earlier license version, but it is no longer active. Your new license has a new credential number. The DMV keeps both in their records so they can track your license history if needed.
Do I need my credential number to drive?
No. You only need your physical license card to drive. The credential number is for DMV records and official requests. Police and other authorities only look at your main license number and the information on the front of your card.
Where exactly is the credential number on my license?
It is usually on the back of your card, often near the bottom or in a corner, but location varies by state. If you cannot find it on your card, check your online DMV account or call your state DMV with your name and license number, and they will provide it.
Can I look up someone else's credential number?
No. Credential numbers are part of your DMV record and are not public information. Only you, the DMV, and authorized government or law enforcement agencies can access it. You cannot look up another person's credential number without their permission.
