What the audit number is and where to find it
The audit number on a Texas driver's license is a unique identifier printed on the back of the card, usually in the lower right corner. It consists of four digits and serves as a control number for the Department of Public Safety (DPS) to track and verify the authenticity of the license during inspections or audits. The number changes each time you renew your license.
To locate it, flip your license over to the back side. Look for a small four-digit number positioned near the bottom right of the card, often printed in smaller text than other numbers on the license. The exact placement can vary slightly depending on when your license was issued, but it will always be on the reverse side, not the front.
This number is distinct from your driver's license number (which appears on the front), your date of birth, or your license class. It exists solely for DPS record-keeping and verification purposes.

Why DPS uses audit numbers on licenses
State motor vehicle agencies use audit numbers as part of their quality control and anti-fraud systems. Each license produced by DPS is assigned a unique audit number at the time of printing, creating a traceable record that links the physical card to the specific batch and date it was manufactured. This allows DPS staff to identify when and where a particular license was produced.
If a license is reported as lost, stolen, or fraudulent, the audit number helps DPS investigators narrow down the timeframe and production run in question. It also serves as a secondary verification tool when someone presents their license to law enforcement or other agencies that need to confirm the card is genuine.
When you might need to reference your audit number
In most day-to-day situations, you will not need to know or provide your audit number. Police officers, businesses, and other entities that check your license typically focus on your license number, name, and expiration date.
You may be asked for your audit number if you are reporting your license as lost or stolen and DPS needs to verify which specific card was issued to you. It can also come up if you are disputing a record with DPS or if there is a question about whether a license presented to an agency is authentic. Some government offices or financial institutions may request it as part of a verification process, though this is uncommon.
How audit numbers differ across license renewals
Each time you renew your Texas driver's license, DPS issues a new physical card with a new audit number. The old audit number is no longer active and should not be used for any purpose. If you have multiple old licenses from previous renewals, each one will have a different audit number, but only the number on your current, valid license matters.
This rotation of audit numbers is intentional—it prevents someone from using an old audit number to impersonate a current license or to create confusion in DPS records. When you renew, your driver's license number stays the same, but the audit number changes to reflect the new card's production run.
How to verify your license information with DPS
If you need to confirm details about your current license or want to verify that your audit number matches DPS records, you can contact the Texas Department of Public Safety directly. You can reach DPS by phone at 1-888-589-6556 or visit a local DPS office in person with your license.
Online, you can check your license status through the Texas DPS website, though the audit number itself is not typically displayed in online portals—it is information you can see only on the physical card. If you believe there is an error in your license record or if you need to report a lost or stolen license, DPS staff can help you and will reference your audit number as part of their verification process.
What to do if you cannot find your audit number
If your license is worn, faded, or damaged to the point that the audit number is no longer legible, you have two options. You can renew your license early through DPS, which will issue you a new card with a new, readable audit number. Alternatively, if you only need the audit number for a specific verification purpose, you can contact DPS directly and provide your driver's license number and other identifying information, and they can look up the audit number for you.
You do not need to replace your license solely because the audit number is hard to read—the license itself remains valid as long as it has not expired. The audit number is a reference tool for DPS, not something you need to maintain for your own use.
Frequently Asked Questions
Is the audit number the same as my driver's license number?
No. Your driver's license number appears on the front of your card and stays the same throughout your life (unless you request a change). The audit number is a four-digit code on the back that changes every time you renew your license.
Can someone use my audit number to commit fraud?
The audit number alone is not enough to commit fraud—it is a control number for DPS internal use, not a primary identifier. However, you should still protect your entire license from being lost or stolen, as someone with access to the full card could misuse it.
Do I need to memorize my audit number?
No. You only need to know your audit number if DPS specifically asks for it during a verification process. In nearly all situations, your driver's license number is what matters.
What if my audit number is printed incorrectly or is missing?
Contact the Texas Department of Public Safety to report the issue. They can verify your license record and, if necessary, issue a replacement card. You can reach them at 1-888-589-6556 or visit a local DPS office.
Will my audit number change if I renew my license online?
Yes. Whether you renew in person or online, DPS will issue you a new physical card with a new audit number. The renewal method does not affect this process.
