Your credential number is a unique identifier your state assigns to your driver's license, separate from your license number

The credential number on your driver's license is a code that identifies the specific card itself, not you as a person. Your state's Department of Motor Vehicles (or equivalent agency) assigns this number when the license is issued. It stays the same for the life of that particular card — but if you renew your license and receive a new card, you get a new credential number.

This is different from your driver's license number, which is the main number printed on the front of your license. Your license number typically stays with you across renewals, while your credential number changes each time you get a new physical card. Think of the credential number as tracking the card itself, while the license number tracks you as a driver.

You will find your credential number printed on the back of your driver's license, usually in small text. The exact location and format varies by state — some states print it near the barcode, others near the signature line. If you cannot locate it on your card, your state's DMV website will show you where to look for your specific state's format.

Key Takeaways

  • The credential number is separate from your driver's license number, which typically remains the same across renewals.
  • You can find your credential number printed on the back of your driver's license, though the exact location depends on your state.
  • Law enforcement, courts, and some government agencies use credential numbers to track the specific card during traffic stops or legal proceedings.

Where the credential number appears on your card

The location of the credential number varies significantly by state. In many states, it appears on the back of the license in the lower portion, sometimes near the barcode or magnetic stripe. Other states print it in the upper right or left corner. Some states label it clearly as "Credential Number," while others may use abbreviations like "Cred #" or straightforward print it without a label.

If you are having trouble finding it, your state's DMV website usually includes a sample license image showing exactly where the credential number appears. You can also call your local DMV office and they will tell you the specific location for your state's current license design. Since states update their license designs every few years, the position may shift if you have an older card.

Why credential numbers exist and how they are used

States created credential numbers to track individual cards in their system. When a police officer runs your license during a traffic stop, the credential number helps them pull up the exact card that was issued to you, including its issue date and expiration date. This is especially useful when someone has had multiple licenses over the years — the credential number distinguishes between your current card and any previous ones.

Courts and government agencies also use credential numbers in official documents. If you are cited for a traffic violation, the citation will include your credential number so the court can match it to the correct license record. Some states require the credential number when you renew your license online or by mail, as a way to verify that you are the person requesting the renewal.

Insurance companies and loan companies may ask for your credential number as part of identity verification, though they more commonly request your license number. The credential number is primarily used by government agencies rather than private businesses.

Credential number versus driver's license number

Your driver's license number is your primary identifier as a licensed driver. It appears prominently on the front of your card and stays the same throughout your life in most states, even when you renew. Your license number is what you provide when you need to prove you are a licensed driver — for example, when you rent a car or open a bank account.

Your credential number, by contrast, is tied to the physical card. When you renew your license and receive a new card, you keep your license number but receive a new credential number. This system allows the state to track both you as a driver and the specific card in their possession.

In practice, most people will never need to know their credential number. You will use your license number far more often. The credential number matters mainly in official interactions with law enforcement, courts, or the DMV itself.

When you might need to provide your credential number

You may be asked for your credential number in a few specific situations. If you are renewing your license online or by mail, some states require it as part of the verification process. If you are responding to a traffic citation or court summons, the document may ask you to confirm your credential number. Some states also request it when you update your address or other information on your license.

If a government agency requests your credential number, they will usually tell you where to find it. You do not need to memorize it — you can straightforward look at the back of your license when asked. If you have lost your license and need to provide the credential number, contact your state's DMV and they can look it up using your name and license number.

What happens to your credential number when you renew

When you renew your driver's license, you receive a new physical card with a new credential number. The old credential number is no longer active. Your state's DMV keeps a record of both the old and new credential numbers in their system, linked to your license number, so there is a complete history if anyone needs to look it up.

This is why it is important to update your information with the DMV when you renew — they need to know which credential number is currently valid for you. If you have an expired license and someone asks for your credential number, provide the number from your most recent card, not an old one.

Frequently Asked Questions

Is my credential number the same as my license number?

No. Your license number stays the same across renewals and identifies you as a driver. Your credential number identifies the specific card and changes each time you renew your license. Both appear on your license, but they serve different purposes.

What do I do if I cannot find my credential number?

Check the back of your license first — it is usually in the lower section, though location varies by state. If you still cannot locate it, visit your state's DMV website for a diagram showing where it appears on your state's current license design. You can also call your local DMV office and they will tell you where to look.

Do I need to memorize my credential number?

No. You only need it when a government agency specifically asks for it, which is rare. When that happens, you can straightforward look at the back of your license. You do not need to have it memorized or written down.

Will my credential number change if I move to a different state?

Yes. When you get a new driver's license in a different state, you receive a new credential number assigned by that state. Your old credential number is no longer used, though your previous state keeps a record of it.

Can someone use my credential number to commit fraud?

Your credential number alone is not enough to commit fraud — it is not a secret identifier like a Social Security number. However, it should still be treated as part of your personal information. Do not share it with people or websites you do not trust, especially if they are also asking for other identifying details.
