The audit number is a security code printed on your Texas driver's license that helps prevent fraud and forgery

The audit number on a Texas driver's license is a unique code assigned by the Texas Department of Public Safety (DPS) to every license issued. It appears as a series of numbers, usually printed on the back of your license or in a specific location on the front, depending on when your license was issued. This number serves as an internal tracking and verification tool — it lets law enforcement, businesses, and government agencies confirm that your license is genuine and was actually issued by Texas DPS.

You won't need to memorize or use your audit number in everyday life. It's there primarily for verification purposes when someone — a police officer, a bank, an employer — needs to confirm that your license is real. If you're asked to provide your driver's license number for identification, you give the main license number, not the audit number.

The audit number is part of Texas's security features designed to make licenses harder to counterfeit. Along with holograms, microprinting, and other anti-fraud elements, the audit number creates a record that DPS can check against their database to confirm your license's authenticity.

Key Takeaways

  • The audit number is a unique code printed on your Texas driver's license that DPS uses to verify the license is genuine.
  • You do not need to provide or use your audit number for routine identification — it's an internal security tool.
  • Law enforcement and government agencies can check your audit number against DPS records to confirm your license was actually issued.
  • The audit number is one of several security features on modern Texas licenses designed to prevent counterfeiting and fraud.

Where to find the audit number on your license

The location of the audit number depends on when your license was issued. On newer Texas licenses (issued after 2015), the audit number typically appears on the back of the card, often near the bottom or in a corner. On older licenses, it may be printed on the front. If you're unsure where yours is located, look for a series of numbers that doesn't match your main license number or your date of birth.

The audit number is usually smaller than your main license number and may be labeled or may straightforward appear as part of the card's design. It's not something you'll see highlighted or called out prominently — it's intentionally subtle, which is part of what makes it useful as a security feature.

Why DPS uses audit numbers

Texas DPS assigns an audit number to every license as part of a larger system to track and verify licenses. When someone checks your license — whether it's a police officer during a traffic stop, a bank teller opening an account, or a business verifying your identity — they can use that audit number to look up your record in the DPS database. If the audit number doesn't match what's in the system, it signals that the license may be counterfeit or altered.

This system also helps DPS catch duplicate licenses or fraudulent applications. If someone tries to get a license under a false identity or using someone else's information, the audit number system can flag inconsistencies. It's one layer of protection in a multi-layered approach to license security.

What to do if you notice your audit number is missing or unclear

If your license is damaged and the audit number is no longer visible or readable, it doesn't affect your ability to use the license for everyday purposes. However, if someone needs to verify your license through official channels and can't read the audit number, you may be asked to renew your license early.

If you suspect your license has been altered or if the audit number looks wrong to you, contact your local DPS office or the DPS Driver License Division. You can also call the DPS main line at 512-424-2000 to report concerns. If your license has been tampered with, DPS can issue you a replacement.

How audit numbers differ from your main license number

Your main driver's license number is what you use for identification and is the number you provide when asked for your driver's license number. It's printed prominently on the front of your card and is the number tied to your driving record, insurance, and legal identity.

The audit number is separate and serves a different purpose — it's an internal security code that DPS uses to verify the license itself is legitimate. Think of your license number as your identifier and the audit number as proof that the card you're holding is real. You'll never be asked to provide your audit number in normal circumstances.

Audit numbers and license renewal

When you renew your Texas driver's license, you'll receive a new audit number on your new license. The old audit number becomes inactive and is no longer valid for verification purposes. This is another security feature — it prevents someone from using an old, expired license's audit number to create a fake current license.

You don't need to do anything special regarding your audit number during renewal. DPS generates it automatically when your new license is printed. Just make sure you have your current license and any required documents when you renew, and DPS will handle the rest.

Frequently Asked Questions

Can someone use my audit number to commit fraud?

The audit number alone is not enough to commit fraud because it's tied to your specific license card and DPS's database. If someone tries to use a fake audit number or an audit number that doesn't match the license they're presenting, verification will fail. The audit number is designed to prevent fraud, not enable it.

Do I need to memorize my audit number?

No. You don't need to memorize or remember your audit number. It's not used for any transaction or identification you'll do yourself. It's purely a tool for officials and businesses to verify that your license is genuine.

What if my audit number doesn't match the DPS database?

If someone checks your audit number and it doesn't match DPS records, it could mean your license has been altered, is counterfeit, or there's a database error. Contact DPS when ready to report the issue. They can investigate and issue you a replacement license if needed.

Is the audit number the same as a security code?

The audit number is one type of security feature, but it's not the same as other security elements like holograms or microprinting. All of these features work together to make your license harder to counterfeit. The audit number is specifically a tracking and verification tool.

Will my audit number change if I get a duplicate license?

Yes. If you request a duplicate license from DPS (because yours was lost or damaged), the new card will have a different audit number. The old audit number is deactivated and no longer valid.
