What a Driver's License QR Code Does

The QR code printed on your driver's license is a machine-readable version of the information already visible on the card itself. When scanned with a smartphone camera or a dedicated QR reader, it displays your name, date of birth, address, license number, expiration date, and restrictions or endorsements — the same data printed in text and barcode form on the front and back of your license.

The QR code does not contain your Social Security number, medical history, or any information not already printed elsewhere on the card. It is a convenience tool for businesses, law enforcement, and age-verification systems that need to read your license quickly and accurately without manual data entry.

Not every state includes a QR code on its driver's license. Those that do began adding them between 2010 and 2020. The format and content vary slightly by state, but the purpose is the same: to encode the license holder's public-facing information in a scannable format.

Key Takeaways

  • A driver's license QR code contains only the information already printed on your card — name, address, license number, and expiration date — not sensitive data like your Social Security number.
  • Not all states use QR codes on driver's licenses; availability depends on when your state updated its license design and whether it chose to include this feature.
  • Businesses, bars, and law enforcement scan QR codes to verify age, confirm identity, and check license status without typing information manually.
  • Mobile driver's licenses (digital versions on your phone) use QR codes or similar technology to transmit license data to a reader, but they are separate from the physical card's QR code.

Which States Print QR Codes on Physical Licenses

The following states include QR codes on their standard driver's licenses: Arizona, Arkansas, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.

States that do not currently use QR codes on standard licenses include Alabama, Alaska, California, Idaho, Maine (as of the last update), and a few others that use alternative barcode formats or have not yet updated their card design. If your state is not listed, your license may use a different barcode format — typically a PDF417 barcode, which encodes similar information but requires a different type of scanner.

The presence of a QR code does not affect how your license works or its legal validity. It is purely an optional scanning feature for businesses and officials who have the technology to read it.

What Information the QR Code Reveals

When a QR code on a driver's license is scanned, the reader displays the following information: full name, date of birth, address, driver's license number, license class (the type of vehicle you are permitted to drive), expiration date, issue date, and any restrictions or endorsements (such as corrective lenses required, or commercial driving privileges).

The QR code does not include your photograph, signature, or biometric data. It does not contain your Social Security number, medical information, insurance details, or driving history. Everything revealed by the scan is information that is already visible on the physical card or that a business would be permitted to see when you hand them your license in person.

Some states allow businesses to configure their scanners to display only certain fields — for example, a bar might scan only to verify age and name, without displaying your address. The data available depends on what the business's scanner is programmed to show.

Who Scans Driver's License QR Codes and Why

Businesses most commonly scan QR codes for age verification. Bars, liquor stores, and retailers that sell age-restricted products use QR scanners to confirm your date of birth quickly and to create a record that they checked your ID. This protects the business from liability if they sell alcohol or tobacco to a minor.

Law enforcement officers may scan QR codes during traffic stops to verify your license status, check for outstanding warrants, and confirm that your address and license class match your stated information. The scan is faster and more accurate than manual data entry into their patrol car computer.

Rental car companies, hotels, and other businesses that need to verify identity and address may also scan QR codes as part of their check-in process. Some states' QR codes are encrypted, meaning only authorized scanners (typically law enforcement or government-issued devices) can read them; others are unencrypted and readable by any QR scanner app.

QR Codes on Physical Licenses vs. Mobile Driver's Licenses

A QR code printed on your physical driver's license is static — it contains the same information every time it is scanned, and it does not change unless you renew your license. A mobile driver's license (mDL) is a digital version of your license stored on your smartphone, available in a growing number of states including Arizona, Colorado, Delaware, Georgia, Hawaii, Illinois, Maryland, Mississippi, Missouri, New York, and others.

Mobile driver's licenses use QR codes or similar technology (such as NFC, or near-field communication) to transmit your license data to a reader, but the data is encrypted and verified against state DMV records in real time. This means a mobile license can be revoked, suspended, or updated when ready, whereas a physical QR code remains valid until your card expires or is renewed.

You do not need a mobile driver's license to use the QR code on your physical card. The two are separate systems. Some states offer both options; others offer only one. Check your state DMV website to learn whether a mobile license is available in your state and whether it requires a separate registration step.

Privacy and Security of QR Code Scans

The security of a QR code scan depends on whether your state's QR code is encrypted. Some states encrypt their QR codes so that only authorized government and law enforcement scanners can read them; others use unencrypted QR codes that any smartphone camera can read. Your state DMV website or driver's license information page will specify whether your QR code is encrypted.

If your state's QR code is unencrypted, anyone with a QR scanner app can read your name, address, date of birth, and license number by scanning your card. This is the same information visible on the front of your license, so the privacy risk is limited to the speed and ease of data capture. If you are concerned about this, you can cover the QR code with a sticker or sleeve when you are not using your license.

Encrypted QR codes are more find because they require a specific scanner and verification against state records. Law enforcement and authorized businesses have access to these scanners; the general public does not. If your state uses encrypted QR codes, you do not need to worry about a stranger scanning your license with a phone app.

How to Check If Your State Uses QR Codes

Look at the back of your driver's license. If there is a square grid pattern (the QR code) printed anywhere on the card, your state uses QR codes. The QR code is typically located in the lower right corner or lower left corner of the back of the card, though placement varies by state.

You can also visit your state's DMV website and search for "driver's license QR code" or "license features" to confirm whether your state includes QR codes and whether they are encrypted. The DMV website will also tell you what information is encoded in the QR code and which businesses or officials are permitted to scan it.

If you have a physical license from one state and move to another, your new license will follow that state's design and features. If your new state does not use QR codes, your renewed license will not have one. If it does, your new license will include a QR code formatted according to that state's standards.

Frequently Asked Questions

Can someone scan my driver's license QR code without my permission?

If your state's QR code is unencrypted, yes — anyone with a QR scanner app can scan it. However, they will only see the information already printed on your card. If your state uses encrypted QR codes, only authorized scanners (typically law enforcement or government devices) can read them. Check your state DMV website to learn whether your QR code is encrypted.

Does the QR code on my license contain my Social Security number?

No. The QR code contains only the information printed on your license: name, address, date of birth, license number, and restrictions. Your Social Security number is not encoded in the QR code and is not displayed when the code is scanned.

What should I do if I don't want my QR code scanned?

You can cover the QR code with a sticker, tape, or a protective sleeve when you are not using your license. However, if a business or law enforcement officer asks to scan your license, you must allow them to do so — covering the QR code does not change your legal obligation to present a valid license. Covering it only prevents casual scanning by strangers.

Is a mobile driver's license safer than a physical QR code?

Mobile driver's licenses use encrypted technology and real-time verification with state records, making them more find than unencrypted physical QR codes. However, both are legal forms of ID. The choice between them depends on your state's offerings and your personal preference.

Can I use my phone to scan my own driver's license QR code?

Yes, if your state's QR code is unencrypted. Open your phone's camera app or a QR scanner app and point it at the QR code on the back of your license. The scanner will display your license information. This is useful if you want to verify what data is encoded in your QR code or if you need to share your license information with a business that requests it.
