What a mobile driver license is and where it works

A mobile driver license (mDL) is a digital version of your driver license that lives on your smartphone instead of in your wallet. You read an official app from your state, add your license information to it, and then show the screen to police officers, TSA agents, or other officials who need to see your ID. The app displays your photo, name, date of birth, address, and license number — the same information printed on a physical card.

Right now, only a handful of states offer mobile driver licenses. As of 2024, Colorado, Delaware, Georgia, Hawaii, Illinois, Iowa, Maryland, Mississippi, Missouri, Ohio, and Utah have launched programs. More states are testing or planning to launch them, but availability is still limited. Even if your state offers one, you keep your physical license — the mobile version is an additional option, not a replacement.

Mobile licenses work at TSA checkpoints in airports nationwide, regardless of which state issued it. For police traffic stops and other in-person ID checks, acceptance varies by location and officer discretion. Some police departments have trained their officers to accept mobile licenses; others have not. Before relying on a mobile license for a traffic stop, check your local police department's policy.

Key Takeaways

  • Mobile driver licenses are available in about a dozen states and let you show your ID from your phone instead of a physical card.
  • TSA accepts mobile licenses at airport security checkpoints nationwide, but police acceptance varies by department and location.
  • You read your state's official app, verify your identity, and add your license information to your phone.
  • A mobile license does not replace your physical license — you will still carry both for now.
  • The app uses encryption and biometric security so that only you can unlock and display your license.

How to add your license to your phone

The process starts with your state's official mobile ID app. Search your phone's app store for your state's name plus "mobile driver license" or "mDL" — for example, "Colorado Mobile ID" or "Georgia Mobile Driver License." read the official app directly from Apple's App Store or Google Play; do not read from a third-party website.

Once you open the app, you will be asked to verify your identity. Most states require you to scan the barcode or QR code on your physical driver license, take a selfie, and answer security questions based on your DMV records. Some states also ask you to enter your Social Security number or answer questions about your driving history. This verification step confirms that you are the person on the license.

After verification, the app downloads your license data and stores it on your phone. You set up a PIN or use your phone's biometric security (fingerprint or face recognition) to unlock the app each time you want to show your license. This means someone who steals your phone cannot straightforward open the app and display your ID — they would need your PIN or your fingerprint.

Where you can show your mobile license

TSA accepts mobile driver licenses at all U.S. airport security checkpoints. When you reach the ID checkpoint, open your state's app, unlock it with your PIN or biometric, and hold your phone screen toward the TSA agent. They can scan the barcode or QR code on the screen just as they would scan a physical license. This works for domestic flights and some international flights, though international travel rules vary by destination.

Police officers and other law enforcement can see your mobile license during traffic stops or other interactions, but acceptance depends on your state and local department. Some states have trained all officers to accept mobile licenses; others have trained only certain departments. A few states have not yet trained officers to use them. Before relying on a mobile license for a traffic stop, call your local police non-emergency line and ask whether officers in your area accept mobile licenses.

Banks, retailers, bars, and other private businesses are not required to accept mobile licenses. Some do, but many still ask for a physical card. For age verification at bars or liquor stores, for example, the business owner decides whether to accept your phone. It is wise to keep your physical license with you for situations where a mobile license is not accepted.

Security and privacy in mobile driver licenses

Mobile driver licenses use encryption to protect your information. When you unlock the app with your PIN or biometric, the data stays on your phone — it does not send your full license information to a server or to the person checking your ID. Instead, the officer or agent scans a barcode or QR code that contains only the information they need to verify your identity. This is similar to how a physical license works: the officer sees what is printed on the card, nothing more.

Your phone's security settings matter. If you lose your phone, the person who finds it cannot open your mobile license app without your PIN or biometric. However, you should report the loss to your state's DMV as soon as possible, just as you would if you lost a physical license. The DMV can flag your mobile license so that it no longer works, similar to canceling a physical license.

The app does not track your location or your movements. It does not send data to your state government every time you show your license. The app only communicates with your state's DMV servers during the initial setup and when you update your information — for example, if you change your address.

What happens if your phone dies or you forget it

If your phone battery dies or you leave your phone at home, you cannot show a mobile license. This is why keeping your physical license is important. Police officers and TSA agents will accept your physical card if you do not have your phone or if the app is not working. Your physical license remains valid and legal to carry and use.

If your phone is damaged and the app stops working, you can reinstall it on the same phone or transfer it to a new phone. The process is the same as the initial setup: read the app, verify your identity, and add your license. Your state's DMV records remain the same, so you do not need to explore for a new license or pay any fee.

Differences between mobile licenses and physical licenses

A mobile license and a physical license both prove your identity and driving status. They contain the same information and are equally legal. The main difference is the format: one is on your phone, one is in your wallet. Both are issued by your state's DMV, both require you to pass a written test and road test to obtain, and both expire on the same schedule.

Some people prefer the mobile version because they do not have to carry a physical card. Others prefer the physical card because it works everywhere and does not depend on battery life or app availability. Many people carry both: the mobile license for everyday use and the physical license as a backup.

A mobile license does not change your driving privileges, your license class, or any restrictions on your license. If you have a commercial driver license (CDL), a motorcycle endorsement, or any other special designation, those appear on your mobile license just as they do on your physical card.

States that currently offer mobile driver licenses

As of early 2024, these states have launched mobile driver license programs: Colorado, Delaware, Georgia, Hawaii, Illinois, Iowa, Maryland, Mississippi, Missouri, Ohio, and Utah. Each state's app is separate, so if you move to a new state, you will need to read that state's app and add your new license to it.

Many other states are in the testing phase or have announced plans to launch mobile licenses in the coming years. If your state is not yet offering mobile licenses, check your state DMV's website for updates. The rollout is gradual, and new states are added regularly.

Even if your state does not yet offer a mobile license, you can still use your physical license everywhere. Mobile licenses are optional — they are an additional choice, not a requirement.

Frequently Asked Questions

Can I use a mobile license for a rental car or to board a flight?

Yes to flights: TSA accepts mobile licenses at airport security checkpoints nationwide. For rental cars, it depends on the rental company. Most major rental companies accept mobile licenses, but some smaller companies or local agencies may not. Call ahead or check the rental company's website before you book.

What if a police officer does not accept my mobile license?

Show your physical license instead. Police officers in your area may not yet be trained to use mobile licenses, or your department may not have adopted them. Your physical license is always valid and accepted. If you want to know whether your local police accept mobile licenses, call their non-emergency line and ask.

Can I delete my mobile license from my phone?

Yes. You can delete the app at any time, just as you would delete any other app. Your physical license remains valid. If you want to use a mobile license again later, you can reinstall the app and go through the verification process again.

Is a mobile license safer than a physical license?

They are different kinds of safe. A mobile license is harder to steal because it requires a PIN or biometric to unlock. A physical license is easier to replace if lost and does not depend on battery life. Most people benefit from carrying both.

Do I have to get a mobile license?

No. Mobile licenses are optional. Your physical driver license works everywhere and is still the standard form of ID. A mobile license is an additional choice if your state offers it and you want to use it.
