What the audit number is and why it appears on your license
Your audit number is a seven-digit code printed on the back of your Texas driver license, below your license number. It serves as an internal tracking identifier for the Texas Department of Public Safety (DPS) — it is not a Social Security number, a criminal record marker, or a security code you should share with anyone.
The audit number is generated when DPS issues or renews your license. It helps DPS staff locate your record in their system during transactions at a license office, when you call for information, or if you need to dispute something on your record. Each time you renew, you receive a new audit number.
You will not need to memorize or use this number in everyday life. It appears on your physical card so that DPS employees can pull up your file quickly if you visit a license office or call with a question about your specific license.
Key Takeaways
- The audit number is a seven-digit code on the back of your Texas driver license, used only by DPS staff to locate your record in their system.
- A new audit number is assigned each time you renew your license; it is not permanent across renewals.
- You do not need to provide your audit number for routine driving or identification purposes.
- If DPS asks for your audit number during a phone call or office visit, it is a legitimate request to speed up record lookup.
Where to find your audit number on your license card
Turn your Texas driver license over to the back side. The audit number appears in the lower left area of the card, printed in small text. It is a seven-digit number with no letters.
If you have a standard Class C license (for regular driving), a commercial Class A or B license, or a motorcycle endorsement, the audit number location is the same. The number will be visible whether your license is vertical or horizontal format.
If you cannot locate it or the text is too faded to read, you can contact DPS by phone or visit a license office with your license in hand, and staff can read it to you or confirm the number in their system.
When DPS staff will ask for your audit number
DPS employees may request your audit number when you call the DPS customer service line with a question about your specific license record — for example, if you are checking on a renewal status, reporting a lost or stolen license, or asking about a suspension or restriction on your record.
You may also be asked for it if you visit a DPS license office in person. Providing it speeds up the process because staff can pull your file without having to type in your full name and date of birth.
You should never be asked for your audit number by text message, email, or phone call from someone claiming to represent DPS unless you initiated the contact. DPS does not send unsolicited messages asking for license information.
How the audit number differs from your license number
Your license number is the primary identifier on your Texas driver license — it appears on the front of the card and is what law enforcement uses during traffic stops or when running a background check. Your license number stays the same across renewals unless you request a new one.
The audit number, by contrast, is an internal administrative code that changes with each renewal. It is printed on the back and is used only by DPS staff for record management, not by police, employers, or other outside agencies.
If someone asks for your "driver license number," they are asking for the number on the front of your card, not the audit number. The audit number is rarely requested outside of direct contact with DPS.
What to do if your audit number is incorrect or missing
If you notice that the audit number on the back of your license is smudged, faded, or appears to be missing entirely, you can report it to DPS. However, this is not an urgent issue — the audit number is for DPS internal use only and does not affect your ability to drive or use your license for identification.
If you want to report it, visit a DPS license office with your license and let staff know. They can verify the number in their system and note any printing defect. You do not need to renew your license early unless the defect is severe enough that the entire card is unreadable.
If you believe someone has misused your license information or you suspect identity theft, contact DPS directly or file a report with the Texas Attorney General's office. The audit number itself cannot be used to commit fraud because it is not tied to financial accounts or personal identity the way a Social Security number is.
Audit numbers and license renewal in Texas
When you renew your Texas driver license — whether online, by mail, or in person — DPS will assign you a new audit number on your replacement card. Your old audit number becomes inactive.
This means if you renew your license, you should discard the old card and use only the new one. If you keep the old card for reference, remember that its audit number is no longer valid in DPS systems.
You do not need to do anything special to receive your new audit number — it is generated automatically as part of the renewal process. When your new license arrives, the audit number will be printed on the back.
Frequently Asked Questions
Is my audit number the same as my Social Security number?
No. Your audit number is a seven-digit code used only by DPS for internal record management. Your Social Security number is separate and should never appear on your driver license. Do not confuse the two or share your audit number thinking it is sensitive financial information — it is not.
Can I look up someone else's audit number?
No. Audit numbers are internal DPS identifiers and are not public information. You cannot request another person's audit number, and DPS will not provide it to you. Only the license holder and DPS staff can access this information.
What if I lose my license and need to report the audit number?
You do not need to report your audit number when you lose your license. Contact DPS to report the loss and request a replacement. DPS will issue you a new license with a new audit number. Provide your license number and date of birth instead.
Do I need my audit number to renew my license online?
No. The Texas DPS online renewal system uses your license number, date of birth, and other personal information — not your audit number. You only need your audit number if DPS staff specifically ask for it during a phone call or office visit.
Will my audit number change if I update my address or name?
If you update your address or name without renewing your entire license, your audit number stays the same. The audit number only changes when you receive a new physical license card through a full renewal or replacement.
