Your audit number is on your driver's license itself, usually in small print on the back

Your audit number is a reference code printed directly on your physical driver's license. Most states place it on the back of the card, often near the bottom or in a corner, printed in smaller text than your name or license number. The exact location and format varies by state — some call it an "audit number," others label it differently, and a few states do not print one at all.

If you cannot find it on the card, the next step is to contact your state's Department of Motor Vehicles (DMV) or equivalent agency. They can look up the number using your license number or personal information. You will need to call, visit in person, or use your state's online portal if one exists.

Key Takeaways

  • The audit number is printed on the back of your physical driver's license in small text, though its exact location differs by state.
  • If you cannot locate it on the card, your state's DMV can provide the number by phone, in person, or through an online account portal.
  • Some states do not issue audit numbers, so if you cannot find one after checking both the card and contacting the DMV, your state may not use them.
  • You will need your license number or personal identifying information when you contact the DMV to request this information.

Checking the physical card first

Start by looking at both sides of your driver's license carefully. Turn the card over and scan the back for small printed text. The audit number is typically a short string of numbers or alphanumeric characters. It may be labeled "audit number," "control number," "sequence number," or something similar depending on your state.

If the print is faded or difficult to read, try holding the card under good lighting or using a magnifying glass. Wear and tear from carrying the card in a wallet can sometimes make the text harder to see. If you have an older license, the formatting or location may differ from newer cards issued in your state.

Contacting your state DMV by phone

Call your state's Department of Motor Vehicles directly and ask for your audit number. You will need to provide your driver's license number and possibly other personal information like your date of birth or address to verify your identity. The DMV representative can read the number to you over the phone or tell you where to find it on your card.

To find your state's DMV phone number, search "[your state] DMV phone number" online or visit your state's official government website. Wait times can be long during peak hours, so calling early in the morning or mid-week may be faster. Some states also offer callback options so you do not have to hold.

Using your state's online DMV portal

Many states allow you to log into an online account through the DMV website to view your license information, including the audit number. You will typically need your license number and a password or PIN you created when you registered for the account. If you do not have an online account yet, you can usually set one up on the DMV website in a few minutes.

Once logged in, look for a section labeled "License Information," "My License," or "License Details." The audit number should be displayed alongside your other license information. This method is often faster than calling and works at any time of day.

Visiting the DMV in person

If you prefer to handle this face-to-face, visit your local DMV office with your driver's license and a form of identification. A staff member can look up your audit number and either show you where it is on your card or write it down for you. Bring your license itself so they can point out the exact location if you want to know where to find it in the future.

Check your state's DMV website for office hours and locations near you. Some offices accept walk-ins, while others require you to take a number or book an appointment. Going in person can take longer than a phone call, but it guarantees you will get an answer the same day.

What to do if you cannot find an audit number

Not all states print audit numbers on driver's licenses. If you have checked your card thoroughly, called the DMV, and checked your online account and the DMV still tells you there is no audit number on file, your state straightforward may not use them. This is normal and does not mean anything is wrong with your license.

If you need a reference number for your license for a specific purpose — such as a court document, insurance claim, or government form — ask the organization requesting it whether they will accept your license number instead. In most cases, your actual driver's license number serves the same purpose as an audit number.

Frequently Asked Questions

Why would I need my audit number?

Courts, insurance companies, or government agencies sometimes request it as a way to verify your identity or confirm details about your license. It is less common than your license number, but some forms or processes ask for it specifically. If you are unsure whether you need it, ask the organization requesting it what they will use it for.

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

No, they are different. Your driver's license number is the main identifier on your license. The audit number is a separate code, usually shorter, printed elsewhere on the card. Do not confuse the two when filling out forms.

Can I get my audit number if my license is expired?

Yes. The DMV can look up information from expired licenses. Call your state DMV or visit in person with your expired license and another form of identification, and they can provide the audit number. You do not need to renew your license to get this information.

What if I lost my driver's license?

Contact your state DMV and explain that you lost your license. They can look up your audit number using your personal information like your name, date of birth, and address. You will likely need to order a replacement license at the same time, which involves a fee that varies by state.
