The audit number is a six-digit code printed on the back of your Texas driver's license that helps the state verify the license is genuine

The audit number appears as a small six-digit number on the back of your Texas driver's license, usually near the bottom or in the security features area. It is not a personal identifier tied to your name or driving record — it is a verification code that the Texas Department of Public Safety (DPS) uses to confirm your license was issued legitimately and has not been altered or counterfeited.

When a police officer, employer, or other official scans or manually checks your license, they can use the audit number to verify it against DPS records. This is part of the security system built into modern Texas licenses to prevent fraud and forgery.

Key Takeaways

  • The audit number is a six-digit security code on the back of your Texas driver's license that helps verify the license is real.
  • It is not the same as your driver's license number, which appears on the front and is tied to your driving record.
  • You do not need to memorize or provide your audit number for routine driving — it is mainly used by law enforcement and official checkers.
  • If your license is damaged, lost, or you suspect it has been tampered with, you can request a replacement from DPS and receive a new audit number.

How the audit number differs from your driver's license number

Your Texas driver's license number (the main number on the front) is your personal identifier within the DPS system. It connects to your driving history, violations, points, and registration. The audit number is separate — it is a security feature that changes with each new license you receive.

When you renew your license, you keep the same driver's license number, but you receive a new audit number. This means the audit number is tied to that specific physical card, not to you as a person. If someone tries to use a counterfeit or altered license, the audit number will not match DPS records, and the fraud can be detected.

Why Texas includes an audit number on licenses

Modern driver's licenses are security documents. They are used to verify identity for air travel, banking, employment, and law enforcement stops. Without security features like the audit number, it would be easier for someone to forge a license or alter an existing one.

The audit number is part of a larger set of security measures on Texas licenses, including holograms, microprinting, and color-shifting elements. These features make it harder for counterfeiters to create fake licenses and easier for officials to spot them when they do.

When you might need to reference your audit number

In most everyday situations, you will not need to know or provide your audit number. You do not need it to renew your license online, take a driving test, or register your vehicle. Police officers and security personnel have tools to scan or look up the audit number themselves when they need to verify your license.

The main exception is if you are reporting your license lost or stolen, or if you suspect someone has counterfeited your license. In those cases, you can contact DPS directly and provide your driver's license number, and they can pull up the audit number associated with your card to investigate.

What to do if your audit number does not match DPS records

If a police officer or official tells you that your audit number does not match their records, it usually means one of three things: the license is damaged and the number is hard to read, the scanner did not pick it up correctly, or there is a genuine problem with the license.

If you believe your license is fraudulent or has been tampered with, do not try to use it further. Contact the Texas DPS Driver's License Division directly with your driver's license number and explain the situation. They can check their records and issue you a replacement license with a new audit number at no charge if the problem is on their end.

Getting a replacement license with a new audit number

You can request a replacement Texas driver's license for several reasons: damage, loss, theft, or name change. Each replacement comes with a new audit number, even though your driver's license number stays the same.

To get a replacement, visit your local DPS office in person with proof of identity and Texas residency. You will need to bring documents like a birth certificate, Social Security card, or passport. The replacement usually takes a few minutes if you are renewing in person, though mail-in replacements take longer. You will pay a replacement fee (the amount varies, so check the DPS website for current pricing).

Frequently Asked Questions

Is the audit number the same as my driver's license number?

No. Your driver's license number is on the front and is your permanent identifier in the DPS system. The audit number is a six-digit security code on the back that changes each time you get a new license.

Do I need to memorize my audit number?

No. You do not need to memorize or carry a record of your audit number. It is used by officials who scan or verify your license, not by you in daily life.

What happens if my audit number is worn off or hard to read?

If the audit number is damaged or illegible, your license may fail verification checks. You can request a replacement license from DPS, which will have a new, readable audit number printed on it.

Can someone forge an audit number on a fake Texas license?

It is difficult but not impossible. That is why DPS uses multiple security features together — holograms, microprinting, and the audit number — so that officials can cross-check them. A forged license usually fails at least one of these checks.

Will my audit number change if I renew my license online?

Yes. Even if you renew online, you will receive a new physical license card in the mail with a new audit number. Your driver's license number stays the same.
