The audit number is a six-digit code printed on the back of your Texas driver's license, usually in the lower right area near the expiration date.
The audit number on a Texas driver's license is a unique identifier that the Department of Public Safety uses to track and verify license records. It appears as a six-digit number and is separate from your driver's license number itself. This code is printed on the back of the card, not the front, which is why many people don't notice it at the first glance.
The audit number serves as an internal reference for the state's licensing system. When you contact the Department of Public Safety about your license, renew your license, or need to verify your identity for certain transactions, you may be asked to provide this number. It helps the agency pull up the correct record quickly, especially if multiple people share similar names.
Key Takeaways
- The audit number is a six-digit code located on the back of your Texas driver's license, typically in the lower right corner.
- This number is different from your driver's license number and serves as an internal reference code for the Department of Public Safety.
- You may need to provide the audit number when renewing your license, requesting records, or verifying your identity with state agencies.
- The exact position of the audit number can vary slightly depending on when your license was issued, but it is always on the back of the card.
How to locate the audit number on the back of your card
Turn your Texas driver's license over so you are looking at the back side. The audit number appears as a six-digit sequence printed in small text. Look toward the lower right portion of the card, near where the expiration date is shown. The number is typically printed in black ink and may be labeled or straightforward appear as a standalone six-digit code depending on your license design.
If your license was issued several years ago, the formatting and position may differ slightly from newer licenses. Older Texas licenses sometimes place the audit number in a different location on the back, but it remains on the reverse side of the card. If you have difficulty locating it, hold the card up to good lighting — the small print can be hard to read in dim conditions.
Why the Department of Public Safety uses this number
The audit number is part of the state's internal record-keeping system. When you contact the Department of Public Safety by phone, mail, or in person, providing this number helps staff locate your file without having to search by name alone. This is especially useful if your name is common or if there are similar records in the system.
The number also appears on official documents the state sends you, such as renewal notices or license replacement confirmations. This consistency makes it easier to match your physical card to your file in the state's database. If you ever need to dispute information on your license or request corrections, having the audit number on hand speeds up the process.
When you might need to provide the audit number
You may be asked for the audit number in several situations. If you are renewing your license online or by mail, the renewal form or website may request it to verify your identity. If you contact the Department of Public Safety to report a lost or stolen license, ask about a duplicate, or request a name change, staff may ask for this number to pull up your record.
Some third-party services that verify driver's licenses — such as certain financial institutions or government agencies — may also request the audit number as part of their verification process. Having it readily available can make these transactions faster. If you do not have your physical license with you, you can still contact the Department of Public Safety and provide your name and date of birth, but having the audit number makes the process smoother.
What to do if you cannot find the audit number
If your license is too worn or damaged to read the audit number clearly, you can contact the Department of Public Safety directly. Call the Driver's License Division at 1-888-589-6789 or visit a local Driver's License office in person. Staff can look up your record using your name and date of birth and provide you with the audit number if you need it.
You can also request a replacement license if the card is damaged or illegible. A replacement license will have a new audit number printed on it. The Department of Public Safety can process replacement requests online through their website, by mail, or in person at a local office. Keep in mind that a replacement license is different from a renewal — it is a new card issued before your current one expires.
Differences between the audit number and your driver's license number
Your driver's license number is the main identifier on the front of your card. It is a unique number assigned to you by the state and remains the same throughout your life (unless you request a change). This is the number you provide when you are pulled over by law enforcement, when you explore for credit, or when you need to verify your identity in most situations.
The audit number, by contrast, is an internal code used by the Department of Public Safety. It is not the number you typically provide to employers, banks, or law enforcement. The audit number is primarily for state record-keeping and verification purposes. Understanding the difference helps you know which number to provide in different situations — your driver's license number for most everyday uses, and the audit number only when the Department of Public Safety or a state agency specifically requests it.
Frequently Asked Questions
Is the audit number the same as my driver's license number?
No. Your driver's license number is the main identifier on the front of your card and is what you provide to law enforcement and most other organizations. The audit number is a separate six-digit code on the back used only by the Department of Public Safety for internal record-keeping.
Do I need to memorize my audit number?
You do not need to memorize it. Keep your physical license with you or note the number in a safe place if you think you might need it. Most of the time, you will only need to provide it if the Department of Public Safety asks for it directly.
Will my audit number change if I renew my license?
Yes. When you renew your Texas driver's license, you receive a new card with a new audit number. The audit number is tied to that specific card, not to you as a person. Your driver's license number, however, stays the same across renewals.
Can I look up my audit number online?
The Department of Public Safety does not provide a public online tool to look up your audit number. You can find it on the back of your physical license, or you can contact the Driver's License Division at 1-888-589-6789 to request it.
What if my license is laminated and I cannot read the audit number?
If the number is illegible, contact the Department of Public Safety or visit a local Driver's License office. They can provide the audit number from your record. You can also request a replacement license if the card is too damaged to read.
