Your credential number is a unique identifier printed on your driver's license that the DMV uses to track your record
The credential number is a separate number from your driver's license number. It appears on your physical license card and in DMV records, and it stays with you even if you renew your license or move to a different state. The credential number is not your Social Security number, date of birth, or license number — it is its own distinct code that the DMV assigns when you first receive a license.
You will need your credential number when you contact the DMV about your record, request a replacement license, or handle certain administrative tasks. It is also used by law enforcement and other agencies that access DMV records. Understanding where to find it and what it does can save you time when dealing with the DMV.
Key Takeaways
- Your credential number is a unique DMV identifier separate from your license number, and it remains the same throughout your driving record.
- The credential number appears on the back of your physical driver's license card in most states, though placement varies by state.
- You need your credential number when requesting records, reporting a lost or stolen license, or handling certain DMV transactions by phone or online.
- If you cannot locate your credential number on your card, you can contact your state DMV directly with your name and date of birth to retrieve it.
Where the credential number appears on your license
The location of the credential number on your driver's license varies by state. In most states, it is printed on the back of the card, often near the bottom or in a corner. Some states place it on the front, usually below or above the main license number. A few states use different terminology — some call it a "document number," "credential ID," or "control number" — but it serves the same purpose.
The credential number is typically a six- to eight-digit code, though the exact format depends on your state's DMV system. It is printed in a smaller font than your license number, so you may need to look carefully. If your license is worn or faded, the credential number may be harder to read, but it should still be visible.
If you have a REAL ID-compliant license, the credential number is still present and functions the same way. The REAL ID designation does not change how the credential number works or where it appears.
When you need to provide your credential number
The DMV asks for your credential number in specific situations. If you call your state DMV to check your driving record, report a suspended license, or ask about points on your record, the representative will often request your credential number to pull up your file quickly. This is faster than spelling out your full name or providing your Social Security number.
You will also need your credential number if you report your license lost or stolen and request a replacement. When you explore for a duplicate license online or by mail in many states, the system asks for the credential number to verify that you are the person requesting the replacement. If you are transferring your license from another state, some DMVs ask for your old credential number to link your records.
Credential numbers are also used by insurance companies, law enforcement, and other agencies that need to verify information on your license. If you are involved in a traffic stop or accident, the officer may reference your credential number in the report.
How to find your credential number if you cannot locate it
If your license is damaged, faded, or you straightforward cannot find the credential number on the card, contact your state DMV directly. You will need to provide your full name, date of birth, and address. The DMV representative can look up your credential number in their system and provide it to you over the phone.
Many states also allow you to retrieve your credential number online through your DMV account portal. If your state offers online account access, log in with your license number and date of birth, and your credential number should appear in your record summary. This is often faster than calling.
If you have a copy of your driving record on file — either from a previous DMV request or from your insurance company — your credential number may be printed on that document as well. Check any official DMV paperwork you have received in the past.
Credential number versus license number: what is the difference
Your license number and your credential number are two separate identifiers. Your license number is the primary number on your card and is what most people think of as their "driver's license number." It is the number you provide when you are pulled over or when you give your license to a business.
Your credential number is an internal DMV tracking code. It does not change when you renew your license, but your license number may change depending on your state's renewal process. Some states issue a new license number with each renewal; others keep the same number. Your credential number, however, stays the same throughout your entire driving record, even if you move to a different state and transfer your license.
Think of the credential number as your permanent DMV file identifier, while your license number is the number printed on the card you carry. Both are important, but they serve different purposes in the DMV system.
State-by-state differences in credential number placement and format
Credential number placement and terminology vary across states because each state runs its own DMV system. Some states prominently display the credential number on the back of the card; others print it in smaller text on the front. A few states use abbreviations like "CID" (Credential ID) or "Doc #" (Document Number) instead of spelling out "credential number."
The format also differs. Some states use a six-digit code, while others use eight digits or a combination of letters and numbers. If you move to a new state and transfer your license, your new state will assign you a new credential number in their system, even though your old credential number remains in your previous state's records.
If you are unsure where your credential number is located on your specific state's license, check your state DMV's website. Most state DMV sites include a diagram or description of where each element appears on the license card. You can also call your state DMV and ask them to describe the location for your particular license type.
What happens if you lose or forget your credential number
Losing track of your credential number is not a serious problem. You do not need to memorize it or carry it separately. If the DMV asks for it and you do not have it on hand, you can provide your license number instead, and the representative can look up your credential number in their system. It may take a few extra seconds, but the transaction will still go through.
If you are filling out an online form and the system requires your credential number, you can usually find it by logging into your DMV account or by calling the DMV before you submit the form. Some online systems also allow you to search by license number if you do not have the credential number available.
The only time a missing credential number might cause a delay is if you are requesting a replacement license and the system cannot verify your identity without it. In that case, the DMV will ask for additional information like your Social Security number or date of birth to confirm who you are.
