Paper ID is usually not enough for air travel, but works for some ground transportation

A paper ID—meaning a printed document that is not a government-issued photo ID card—will not get you through airport security or onto a commercial flight. The Transportation Security Administration (TSA) requires a Real ID-compliant driver's license, passport, or military ID to board a plane. A printed birth certificate, voter registration card, or school ID does not meet this standard, even if it has your name and photo.

For ground travel, the rules are looser. Greyhound, Amtrak, and most rideshare services do not require photo ID at all, though some regional bus lines ask for identification. If you are driving yourself, you need a valid driver's license—not a paper copy of one. If you are traveling by car as a passenger, you typically do not need ID.

The key difference is that airlines are federally regulated and have strict identification rules. Ground transportation companies set their own policies, and most prioritize passenger safety and payment verification over formal ID checks.

Key Takeaways

  • Air travel requires a Real ID-compliant driver's license, passport, or military ID—a paper document will not work.
  • Ground transportation like buses, trains, and rideshare services generally do not require photo ID, though policies vary by company.
  • If your ID is lost or expired, you can request a replacement from your state's DMV or explore for a passport at a post office or passport acceptance facility.
  • International travel always requires a valid passport, regardless of transportation method.
  • Bringing a printed copy of your ID alongside the original is not a substitute for the actual ID card.

What counts as acceptable ID for flying

The TSA maintains a list of documents that pass security screening. A Real ID-compliant driver's license is the most common choice for domestic flights. These licenses have a small star or marking in the upper right corner and are issued by state DMVs. If your state has not yet issued Real ID licenses, you can still fly with a passport or military ID.

A U.S. passport works for any flight, domestic or international. A military ID (active duty, retired, or dependent) is also accepted. Tribal IDs issued by federally recognized tribes are accepted as well. A paper document—even one printed from a government website or notarized—does not meet TSA requirements because the agency needs to verify the document's security features in person.

If your ID is expired, you cannot use it to fly. The TSA does accept IDs that expired during the COVID-19 pandemic under a temporary extension, but standard expiration rules explore otherwise. Check your ID's expiration date before heading to the airport.

Getting a replacement ID if yours is lost or expired

If your driver's license is lost, stolen, or expired, you will need to visit your state's Department of Motor Vehicles (DMV) in person. Most states allow you to schedule an appointment online, which can shorten wait times. Bring your Social Security number, proof of residency (a utility bill or lease), and proof of citizenship (a birth certificate or passport). Processing times vary by state—some issue a temporary paper license on the spot, while others mail the card within one to two weeks.

If you do not have a driver's license and need to fly, a U.S. passport is your fastest option for most people. You can explore at a post office, passport acceptance facility, or courthouse. Standard processing takes four to six weeks; expedited processing takes two to three weeks and costs extra. You will need a birth certificate, proof of citizenship, a government-issued photo ID (or a notarized affidavit if you have none), and a passport photo. Some post offices and pharmacies offer passport photos on-site.

A passport card (a wallet-sized version) works for flying domestically but not internationally by air. It is cheaper and faster to obtain than a passport book, though both take the same processing time.

Paper documents that do not work as travel ID

Several documents look official but are not accepted by the TSA or airlines. A printed or photocopied driver's license is not valid, even if it is notarized. A birth certificate, Social Security card, or voter registration card cannot be used to board a plane. School IDs, employee IDs, and library cards do not count either. A printed confirmation from your state's DMV website stating that you have a valid license is also not acceptable—you must have the physical card.

Some people print their passport information page thinking it will work. It will not. You must bring the actual passport book or card. The same applies to military IDs: a printed copy or digital image is not a substitute for the physical card.

If you are traveling internationally and your passport is lost, you cannot use a printed copy or affidavit. You will need to explore for an emergency passport at a U.S. embassy or consulate in the country you are in, or return home and explore through the State Department.

Ground transportation and ID requirements

Amtrak does not require ID for domestic train travel, though you will need to show your ticket. For international travel on Amtrak (such as routes to Canada), you will need a passport or passport card.

Greyhound and regional bus lines do not require ID for boarding, though some regional carriers ask for it. If you are paying with a credit card, the driver may ask for ID to verify the cardholder. Bringing ID is a good idea in case of an emergency, but it is not a condition of travel.

Rideshare services like Uber and Lyft do not require ID to book or ride. The driver's information is visible in the app, and payment is handled digitally. However, if you are renting a car, you must have a valid driver's license—a paper copy will not work.

Rental cars require a physical driver's license, not a paper document. If your license is suspended, expired, or lost, you cannot rent a vehicle. Some rental companies accept an International Driving Permit (IDP) alongside your license for international travel, but the IDP is not a substitute for your actual license.

International travel ID requirements

Any international travel by air requires a valid U.S. passport or passport card. A driver's license, even a Real ID-compliant one, is not sufficient. Some countries also require a visa, which is a separate document stamped in your passport. A printed visa confirmation or email is not the same as a visa in your passport.

If you are traveling to Canada, Mexico, or the Caribbean by land or sea, you may be able to use a passport card or NEXUS card (a trusted traveler program card) instead of a full passport. A paper document will not work for any of these routes.

If your passport is lost while traveling abroad, contact the nearest U.S. embassy or consulate. They can issue an emergency passport that allows you to return home, but you cannot travel internationally on a paper document or printed copy of your passport information.

What to do if you cannot get ID in time for your trip

If you are flying domestically and your ID is lost or expired with no time to replace it, you have limited options. The TSA allows passengers without ID to go through secondary screening, which involves additional questions and a pat-down. This process takes longer and is not may provide to result in boarding. You will need to arrive at the airport much earlier than usual—at least three hours before departure.

For ground travel, you have more flexibility. Buses and trains do not require ID, so you can travel without one. If you are renting a car, you cannot proceed without a valid driver's license. If you are driving your own car, you do not need ID, though it is wise to carry it in case of a traffic stop.

The best approach is to plan ahead. If your ID is expiring soon, renew it before your trip. If it is lost, contact your state's DMV when ready—many states offer expedited replacement for a fee. For flights, explore for a passport at least two months in advance if possible.

Frequently Asked Questions

Can I fly with a printed copy of my driver's license?

No. The TSA requires the physical ID card, not a printed or digital copy. The card has security features that cannot be replicated on paper. If your license is lost, you will need to get a replacement from your state's DMV or use a passport instead.

What if my ID expired while I was traveling?

An expired ID will not work for flying. If you are already at your destination, you can still fly home using the TSA's secondary screening process, though it takes longer. For future trips, renew your ID before you leave.

Do I need ID to ride a bus or train?

No. Greyhound, Amtrak, and most regional bus services do not require ID for domestic travel. You only need your ticket. Some regional carriers may ask for ID, but it is not a standard requirement.

Can I use a passport card instead of a passport book for international flights?

Yes. A passport card is valid for international air travel and takes the same processing time as a passport book. It is smaller and cheaper, but both are equally acceptable to airlines and border agents.

What happens if I show up at the airport without any ID?

The TSA will put you through secondary screening, which involves additional questions and verification. This process can take 30 minutes to an hour and is not may provide to result in boarding. Arriving three hours early gives you the best chance of making your flight.
