The audit number is a security feature, not a personal identifier

The audit number on your Texas driver's license is a random string of numbers and letters printed on the back of your card. It serves one purpose: to help the Texas Department of Public Safety (DPS) verify that your license is genuine and hasn't been altered or counterfeited. It is not tied to your identity, your driving record, or any personal information about you.

Every Texas driver's license has an audit number in a different location depending on when it was issued. On newer licenses (issued after 2017), you'll find it printed near the bottom of the back side. On older licenses, it may appear in a different spot. The number changes every time you renew your license, so it's unique to that specific card.

You won't need to memorize or use this number in your daily life. It exists for law enforcement, businesses checking IDs, and DPS staff who need to confirm your license is real. If someone asks you for your audit number outside of an official context, that's a red flag for potential fraud.

Key Takeaways

  • The audit number is a security code printed on the back of your Texas driver's license that helps verify the card is authentic.
  • It is randomly generated and changes each time you renew your license; it has no connection to your personal identity or driving history.
  • You do not need to provide this number for routine driving tasks like traffic stops or vehicle registration.
  • Law enforcement and ID-checking businesses use the audit number to confirm your license hasn't been forged or tampered with.

Where to find the audit number on your card

On Texas licenses issued after 2017, look at the back of your card near the bottom edge. The audit number appears as a series of characters, usually in a smaller font than your name or license number. It's printed in the same color as other security text on the back.

If your license was issued before 2017, the location may differ slightly, but it will still be on the back of the card. When you renew your license, the new card will have a completely different audit number. This is intentional—it prevents someone from using an old audit number to forge a new card.

Why Texas uses audit numbers on licenses

Texas added audit numbers as part of a broader security upgrade to driver's licenses. The goal was to make licenses harder to counterfeit and easier for officials to verify quickly. A police officer or business checking your ID can use the audit number as one of several checks to confirm the card is legitimate.

Counterfeiting driver's licenses is a federal crime, and security features like audit numbers are one tool law enforcement uses to catch forged documents. The random nature of the number—the fact that it doesn't follow a predictable pattern—makes it much harder for someone to create a fake license that will pass inspection.

What the audit number is not

The audit number is not your driver's license number. Your actual license number appears on the front of the card and is what identifies you to the state. The audit number is purely a security feature with no personal data attached to it.

It is also not a tracking number, a code that reveals information about your driving record, or anything that ties back to your personal history. If you look up your license number in the Texas DPS system, the audit number won't appear—it's only printed on the physical card itself.

What to do if your audit number is damaged or unclear

If the audit number on your license is worn, faded, or damaged to the point where it's unreadable, it doesn't affect your ability to drive or use your license for most purposes. However, if you're in a situation where someone needs to verify your license's authenticity and can't read the audit number, you may be asked to provide additional proof of identity.

If your entire license is damaged or worn, you can renew it early through the Texas DPS. You don't have to wait until your expiration date. Visit the DPS website or a local driver's license office to start the renewal process. When you receive your new license, it will have a fresh, clear audit number printed on the back.

How audit numbers fit into Texas license security

The audit number is one of several security features on a modern Texas driver's license. Your card also includes a hologram, a ghost image of your photo, microprinting, and other anti-counterfeiting measures. Together, these features make it very difficult for someone to create a fake license that will fool trained eyes or security scanners.

When a police officer or business scans your license, they may check the audit number against the card's other features to confirm everything matches and the card is genuine. This multi-layer approach is standard across most U.S. states and is considered one of the most effective ways to prevent ID fraud.

Frequently Asked Questions

Do I need to tell anyone my audit number?

No. You should never share your audit number with anyone unless you're in an official situation where a police officer or government employee is verifying your license in person. If someone asks for it online or over the phone, that's a scam.

What happens if I lose my license and someone finds the audit number?

The audit number alone cannot be used to commit fraud or access your personal information. It's only useful as a security check when paired with the physical card itself. If you lose your license, report it to the Texas DPS and request a replacement; your new card will have a different audit number.

Can I look up my audit number online?

No. The Texas DPS does not publish audit numbers online or make them available through any public database. The audit number only appears on the physical card and is meant to be checked in person by authorized officials.

Does the audit number change if I renew my license?

Yes. Every time you renew your Texas driver's license, you receive a new card with a new audit number. The old number is no longer valid and serves no purpose once your new license is issued.
