Your audit number is a unique identifier printed on your physical driver's license or ID card

Your audit number is a multi-digit code that appears on your driver's license or state ID card. It is not the same as your license number. The audit number is used by your state's Department of Motor Vehicles (DMV) to track and verify your license record in their system. You will need it if you are disputing a suspension, checking the status of a renewal, or responding to a notice from the DMV.

The location of the audit number varies by state. On most licenses, it appears in small print near the bottom of the card, often labeled as "Audit #", "Control #", or "Sequence #". Some states print it on the back of the card instead of the front. If you cannot find it on your physical card, you can retrieve it from your DMV record online or by calling your state's DMV directly.

Key Takeaways

  • Your audit number is printed on your physical driver's license or ID card, usually in small print near the bottom or on the back.
  • The label and exact location differ by state — look for "Audit #", "Control #", or "Sequence #".
  • You can find your audit number by logging into your state's DMV online portal, calling the DMV, or visiting a local office in person.
  • You will need your audit number when disputing a suspension, checking license status, or responding to DMV notices.
  • If your license is lost or expired, your state's DMV can provide the audit number from their records without requiring the physical card.

Check the physical card first

Start by looking at your current driver's license or state ID card. Hold it up to the light and examine both the front and back carefully. The audit number is typically printed in small text and may be straightforward to miss. On many licenses, it sits near the bottom of the front side, sometimes below your signature or in a corner. On others, it is on the reverse side near security features or additional identification numbers.

Write down the exact number you see, including any letters or dashes. The format varies — some states use only numbers, while others mix numbers and letters. If you wear glasses or have difficulty reading small print, use a magnifying glass or take a photo with your phone's camera and zoom in on the image.

Use your state's DMV online portal

Most states offer an online DMV portal where you can log in with your license number, date of birth, and other personal information. Once you access your record, your audit number will be displayed alongside your license details, status, and any active suspensions or restrictions.

To find your state's portal, search "[Your State] DMV online services" or visit your state's official DMV website. Look for a link labeled "Check License Status", "View My Record", or "License Information". You will need to create an account or log in if you already have one. The process usually takes five to ten minutes. This method is fastest if your license is current or if you need to verify information quickly without leaving home.

Call or visit your state's DMV

If you cannot find the audit number on your card or access the online portal, contact your state's DMV directly by phone. Have your full name, date of birth, and license number ready. The DMV representative will look up your record and provide your audit number over the phone. This method works even if your license is suspended, expired, or lost.

You can also visit a local DMV office in person. Bring a photo ID and your license number if you have it. A staff member will pull your record and provide the audit number. Wait times at DMV offices vary widely by location and time of day — calling ahead to ask about current wait times can save you a trip.

What to do if your license is lost or suspended

If your physical license is lost, stolen, or suspended, you cannot read the audit number from the card itself. In this case, your only options are the online portal or calling the DMV. The DMV's computer system maintains your audit number regardless of your license status, so you can retrieve it even if your license is currently suspended or revoked.

When you call, explain that you need your audit number for a specific reason — for example, to respond to a suspension notice or to check the status of a reinstatement. This helps the representative locate the right record quickly. Some states also allow you to request this information by mail, though it takes longer.

Why your state needs your audit number

The audit number is part of your state's internal tracking system. When you receive a notice from the DMV about a suspension, restriction, or renewal requirement, the notice will include your audit number. If you respond to that notice, you must include the audit number so the DMV can match your response to the correct record in their database.

The audit number also helps prevent confusion if multiple people in your state share a similar name or date of birth. It is a unique identifier that ensures the DMV is looking at your specific record, not someone else's. When you call the DMV to dispute a suspension or ask about your license status, providing your audit number speeds up the process because the representative can pull your exact file without searching through similar names.

Keeping your audit number for future use

Once you find your audit number, write it down and store it somewhere safe — in your phone's notes app, a document on your computer, or a physical notebook. You may need it months or years later if you have a dispute with the DMV or need to verify your record. Having it on hand saves time if you ever need to contact the DMV about your license status.

If you renew your license, your audit number may change depending on your state's system. Check your new license when it arrives and update your records. Some states keep the same audit number throughout your life, while others issue a new one with each renewal. Calling the DMV or checking your online portal after a renewal confirms whether your audit number has changed.

Frequently Asked Questions

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

No. Your license number is the main identifier on your card and is used for everyday purposes like traffic stops or age verification. Your audit number is an internal DMV tracking code used for administrative purposes, disputes, and status checks. Both appear on your license, but they are different numbers.

What if I cannot find the audit number on my license?

Not all states print the audit number on the physical card in an obvious place. If you cannot locate it after checking both sides carefully, log into your state's DMV online portal or call the DMV directly. They can provide it from your record in minutes.

Do I need my audit number to renew my license?

Usually no. Most renewal applications ask for your license number, not your audit number. However, if you are renewing in response to a DMV notice, that notice will include your audit number, and you should reference it in your response to may support the DMV processes your renewal correctly.

Can I use someone else's audit number by mistake?

No. The audit number is tied to your specific DMV record and personal information. If you provide the wrong audit number, the DMV system will not match it to your record, and your request may be delayed or rejected. Always verify you are using your own audit number.

Will my audit number change if I move to a different state?

Yes. When you get a driver's license in a new state, you receive a new audit number from that state's DMV system. Your old state's audit number is no longer relevant. Keep track of your new state's audit number for any future disputes or status checks.
