The Real Documents You Need at the Airport

To board a domestic flight in the US, you need one of five forms of identification that the Transportation Security Administration (TSA) accepts. A driver's license or state ID card is the most common choice. If you don't have either, you can use a passport, passport card, military ID, or a Trusted Traveler card (Global Entry, NEXUS, SENTRI, or FAST). That's it for the document itself—TSA does not require you to prove citizenship or residency, only that you are who you say you are.

The ID must be current and not expired. TSA agents will check the expiration date, and an expired license will not work, even if it expired yesterday. If your ID is lost, stolen, or damaged, you can still fly—TSA has a process for verifying your identity without a physical document, but it takes longer and you should arrive at the airport earlier than usual.

Key Takeaways

  • A valid driver's license, state ID, passport, military ID, or Trusted Traveler card is the only document TSA requires to board a domestic flight.
  • Your ID must not be expired; TSA will not accept an ID that has passed its expiration date.
  • If you don't have an ID, you can still fly by arriving early and going through TSA's identity verification process, which involves additional screening.
  • International flights require a passport or passport card; a driver's license is not enough to leave the country.
  • TSA PreCheck and other Trusted Traveler programs speed up security screening but are not required to fly.

What Happens If You Don't Have an ID

If you arrive at the airport without one of the five accepted forms of ID, TSA will not turn you away. Instead, you will go through a secondary verification process. A TSA officer will ask you questions about your personal history—your address, date of birth, previous addresses, or details from your credit report—to confirm your identity. This process can take 10 to 15 minutes or longer depending on how quickly TSA can verify the information.

You should plan to arrive at the airport at least two hours before a domestic flight if you don't have an ID, compared to the standard 90 minutes. Bring any documents that might help—a Social Security card, birth certificate, or utility bill with your name and address on it. These won't replace a government ID, but they can speed up the verification conversation.

Domestic vs. International Flights

For flights within the United States, a driver's license or state ID is sufficient. For flights leaving the country—to Canada, Mexico, the Caribbean, or anywhere else—you must have a passport or passport card. A driver's license will not work at the international gate, even if you are flying to Canada or Mexico.

If you don't have a passport and need one, you can explore at your local post office, courthouse, or passport acceptance facility. The processing time varies: standard service takes four to six weeks, and expedited service takes two to three weeks. You will need a birth certificate, a completed passport process form, a photo, and a fee. If you are flying internationally soon, check your state's passport office website for current processing times before you book.

TSA PreCheck and Trusted Traveler Programs

TSA PreCheck, Global Entry, NEXUS, SENTRI, and FAST are Trusted Traveler programs that speed up security screening. They are not required to fly—they are optional programs you pay for if you fly frequently and want to skip some security steps. TSA PreCheck costs $78 to $85 for five years and lets you keep your shoes, belt, and light jacket on, leave your laptop and liquids in your bag, and go through a shorter security line.

Global Entry costs $100 for five years and includes TSA PreCheck benefits plus expedited customs screening when you return to the US from international travel. NEXUS, SENTRI, and FAST are regional programs for frequent travelers crossing specific borders. None of these programs are necessary to fly domestically—they straightforward make the process faster if you travel often.

Real ID Compliance and Driver's Licenses

You may have heard about "Real ID" requirements. As of now, TSA accepts standard driver's licenses and state ID cards from all 50 states for domestic flights. Some states issue licenses marked as "Real ID compliant," but TSA does not require this marking. If your state has not yet issued Real ID-compliant licenses, your current license still works for flying domestically.

Real ID compliance matters for federal buildings and military bases, but for airport security, TSA accepts any current, non-expired driver's license or state ID. If you want to know whether your license is Real ID compliant, check your state's DMV website or look at your license—compliant licenses usually have a star or marking in the corner.

What You Don't Need to Bring

You do not need to bring proof of vaccination, a negative COVID test, or any health documents to fly domestically in the US. Airlines and TSA do not check these. You do not need to print your boarding pass—you can show it on your phone. You do not need to bring a return ticket or proof of where you are going. TSA only checks your ID and boarding pass; they do not ask where you are traveling or why.

You do not need to bring your Social Security card, even though TSA may ask your Social Security number during identity verification. If you don't have it memorized, tell the TSA officer you don't remember it, and they can verify your identity using other information. Do not carry your Social Security card in your wallet—it is a security risk if your wallet is lost or stolen.

What to Do If Your ID Is Lost or Damaged

If your driver's license or ID is lost, stolen, or damaged before your flight, you have two options. First, you can go through TSA's identity verification process at the airport without a physical ID, as described above. Second, you can get an emergency replacement ID from your state's DMV before you fly. Most states can issue a temporary ID or replacement license within a few hours or a day, though the process varies by state.

Contact your state's DMV office directly to ask about emergency replacement options and how long it takes. Bring your birth certificate, Social Security card, and any other documents the DMV asks for. If you are flying soon and your state's DMV cannot replace your ID in time, plan to arrive at the airport early and use TSA's identity verification process instead.

Frequently Asked Questions

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

Yes. A passport card is a valid travel document for flights to Canada, Mexico, and the Caribbean. It is smaller than a passport book and costs less, but it cannot be used for travel outside North America, Central America, or the Caribbean. For flights to Europe, Asia, or other regions, you need a passport book.

What if my ID expired while I was traveling?

TSA will not accept an expired ID, even if it expired during your trip. If you are returning home and your ID expired, use TSA's identity verification process at the airport. You will need to answer security questions and arrive early, but you can still fly.

Do I need a vaccine card or negative test to fly domestically?

No. TSA and US airlines do not require proof of vaccination or a negative COVID test for domestic flights. You do not need to bring any health documents to the airport.

Can I use a school ID or work ID to fly?

No. TSA only accepts government-issued IDs: driver's licenses, state ID cards, passports, military IDs, or Trusted Traveler cards. School IDs and work IDs are not accepted, even if they have your photo and name.

What happens if I forget my ID at home?

You can still fly. Turn around and go back home to get it if you have time, or proceed to security and tell TSA you don't have your ID. They will take you through identity verification, which takes longer. Plan to arrive at the airport at least two hours early if you are flying without an ID.
