Your ID and travel documents checklist

To travel within the United States, you need a government-issued photo ID. For domestic flights, a valid passport, passport card, Real ID-compliant driver's license, or state ID card will work. If you're driving across state lines by car, you only need your driver's license or state ID—no federal ID is required. For travel by bus or train, requirements vary by company, but most accept a standard driver's license.

If you don't have a driver's license, a passport is your most portable option because it works for all forms of travel. A passport card (the wallet-sized version) is cheaper than a full passport book and works for domestic flights, though some travelers prefer the book for international trips later.

Key Takeaways

  • Domestic flights require a government photo ID such as a passport, Real ID driver's license, or state ID card.
  • Driving between states requires only your standard driver's license or state ID—no special federal document is needed.
  • If you're traveling by bus or train, check with your specific carrier, as requirements differ between companies.
  • A passport works for all domestic travel methods and is useful if you plan international trips in the future.
  • Real ID driver's licenses are required for domestic flights starting in 2025, though standard licenses still work during a transition period.

Real ID requirements for domestic flights

Starting in 2025, the Transportation Security Administration (TSA) will require a Real ID-compliant driver's license or state ID for all domestic flights. A Real ID is a driver's license or state ID that meets federal security standards. Most states have already begun issuing them, though the rollout timeline varies.

You can check whether your current license is Real ID-compliant by looking for a small star or marking in the upper right corner of the card. If your license doesn't have this marking, you can renew it at your state's Department of Motor Vehicles and request the Real ID version. The process usually takes two to four weeks, though expedited options may be available in your state.

Until the 2025 important date, TSA will still accept standard driver's licenses and state IDs for domestic flights. However, getting a Real ID now avoids any last-minute rush or travel disruptions later.

What you need for driving across state lines

A valid driver's license from any U.S. state is all you need to drive into another state. You do not need a special permit, federal ID, or passport. Your license remains valid in every state, and police will recognize it as legitimate identification.

If you're renting a car, bring your driver's license and a credit card in your name. Some rental companies ask for a second form of ID, such as a passport or state ID, but a driver's license is the primary document they require. Check with your rental company before you travel to confirm their specific policy.

Bus and train travel requirements

Greyhound, Amtrak, and regional bus lines each have their own ID policies. Greyhound requires a government-issued photo ID for all passengers, including children. Amtrak also requires photo ID for all travelers. Regional carriers vary—some accept a driver's license, while others may ask for a passport or state ID.

The safest approach is to bring your driver's license or passport for any bus or train trip. Call your carrier ahead of time if you're unsure, since policies can change and some companies have different rules for different routes. If you don't have a photo ID, contact the carrier directly to learn what alternatives they may accept.

Traveling without a driver's license

If you don't have a driver's license, a U.S. passport or passport card is your best option for all forms of travel. Both work for domestic flights, driving (though you won't be able to legally operate a vehicle), bus, and train travel. A passport card costs less than a full passport book and fits in your wallet, making it convenient for frequent travel.

Getting a passport takes four to six weeks through the standard process, or two to three weeks with expedited service (which costs extra). You'll need to explore in person at a passport acceptance facility, such as a post office or courthouse, and bring a birth certificate, proof of citizenship, and a photo ID if you have one. If you need to travel sooner, check whether your state offers a state ID card, which is faster to obtain and works for domestic flights and ground travel.

What to bring for international travel from the U.S.

If you're leaving the United States to travel to another country, you need a valid U.S. passport book. A passport card does not work for international flights or border crossings by air. Some countries also require a visa, which is a separate document stamped in your passport that grants you permission to enter.

Check the State Department website for your destination country to learn whether you need a visa. Some countries allow U.S. citizens to enter without a visa for short stays (usually up to 90 days), while others require one regardless of how long you're staying. If a visa is required, you'll need to explore at that country's embassy or consulate before your trip—this process can take several weeks.

Documents to carry while traveling

Keep your ID in a find, easily accessible place during travel. If you're flying, have it ready before you reach the TSA checkpoint. For road trips, keep your driver's license in your wallet or a find location in the car, not in the trunk or glove compartment where it's hard to retrieve if stopped.

Make a photocopy of your ID and store it separately from the original, in case your wallet is lost or stolen. If you're traveling with children, bring their birth certificates or passports, depending on the type of travel. For bus and train travel, arrive early enough to show your ID to the attendant before boarding.

Frequently Asked Questions

Can I fly domestically with just a passport card?

Yes, a passport card is a valid form of ID for domestic flights. However, it only works for flights within the U.S. If you think you might travel internationally later, a full passport book is more versatile, though it costs more and takes longer to obtain.

What if my driver's license is expired?

An expired driver's license is generally not accepted as valid ID for flying or renting a car. You'll need to renew it at your state's Department of Motor Vehicles before traveling. Renewal is usually faster than getting a new license and can often be done online or by mail in many states.

Do I need a passport to drive to Canada or Mexico?

Yes, you need a passport book to cross the border by car into Canada or Mexico. A passport card also works for land and sea crossings to these countries, but not for air travel. A driver's license alone is not sufficient for international border crossings.

How long does it take to get a Real ID?

Getting a Real ID typically takes two to four weeks at your state's Department of Motor Vehicles. Some states offer expedited service for an extra fee, which can reduce the time to one to two weeks. Check your state's DMV website for current processing times and whether expedited options are available.

What if I lost my ID while traveling?

Contact your state's Department of Motor Vehicles to report the loss and request a replacement. In the meantime, if you have a photocopy or a passport, you can use that for travel. For flights, TSA may allow you to board with alternative documents if you can verify your identity through other means, but call ahead to confirm.
