You can fly domestically without a REAL ID or standard state ID card, but you will need an alternative form of identification that the TSA accepts

The Transportation Security Administration (TSA) does not require a REAL ID-compliant card to board a domestic flight. You can use any document from the TSA's approved list, which includes passports, military IDs, tribal IDs, and several other forms of identification. The key is bringing something that proves who you are — the document itself matters less than whether TSA officers recognize it as valid.

If you do not have a state ID card at all, you have more options than you might think. Many people fly with only a passport, and others use military credentials or passport cards. The main thing to understand is that TSA has a specific list of acceptable documents, and you need to bring one of them to the checkpoint.

Key Takeaways

  • A REAL ID-compliant state ID card is not required for domestic flights; the TSA accepts many other forms of identification.
  • Acceptable documents include a valid U.S. passport, passport card, military ID, tribal ID, and permanent resident card (green card).
  • If you have none of these documents, you can still fly but will go through additional screening, which takes longer.
  • International flights require a passport or passport card, not a state ID card of any kind.

TSA-Approved Documents You Can Use Instead of a State ID

The TSA maintains a list of documents that work at the checkpoint. A U.S. passport is the most widely recognized and works for both domestic and international travel. A passport card — the wallet-sized version — also works for domestic flights and is cheaper and faster to obtain than a full passport book.

If you have military service history, a military ID (active duty, retired, or reserve) is accepted. Tribal IDs issued by federally recognized tribes are also valid. A permanent resident card (green card) works for domestic flights. Some people also use enhanced driver's licenses, which are state-issued but different from a standard ID card and include extra security features.

Other less common options include a merchant mariner credential, a U.S. Coast Guard merchant mariner ID, or a Native American tribal document. If you are unsure whether a specific document will work, you can check the TSA website or call the TSA at 1-855-787-2227 before you travel.

What Happens If You Arrive at the Airport Without Any of These Documents

You can still board a domestic flight, but the process is slower and more involved. TSA officers will direct you to a secondary screening area where they will ask you questions to verify your identity — your name, address, date of birth, and other personal details. They may also ask about your travel plans or run background checks.

This secondary screening can add 15 to 45 minutes to your airport time, depending on how busy the checkpoint is and how quickly TSA can verify your information. You will not be turned away, but you should arrive earlier than you normally would. Plan for an extra hour at the airport if you have no ID at all.

For international flights, this option does not exist. You must have a passport or passport card. There is no secondary screening alternative for leaving the country.

Getting a Passport or Passport Card Quickly

If you decide to get a passport before your flight, timing matters. A standard passport book takes 6 to 8 weeks through the mail, though expedited processing cuts that to 2 to 3 weeks for an additional fee. A passport card takes the same amount of time but costs less.

Some passport acceptance facilities offer expedited in-person service, which can produce a passport card in as little as one business day in certain situations, though this is rare and depends on your location. You will need to visit a passport acceptance facility in person — you cannot mail in an process for a first-time passport.

If your flight is very soon and you have no ID, your fastest option is to fly without one and go through secondary screening, or to postpone your trip until you can obtain a passport card.

State ID Cards and REAL ID Compliance: Why the Confusion

Many people think they need a REAL ID-compliant state ID card to fly because of a federal rule that took effect in 2025. That rule requires a REAL ID card (or an acceptable alternative) for entering federal buildings and military bases. However, flying is different — TSA has its own list of acceptable documents, and a REAL ID card is just one option on that list.

A standard state ID card that is not REAL ID-compliant will not work at the TSA checkpoint. But that does not mean you cannot fly. You straightforward need to use a different document from the TSA's approved list instead. The confusion arises because people often assume a state ID card is the default travel document, when in fact a passport is just as valid and more widely useful.

International Travel Without a State ID Card

If you are traveling outside the United States, a state ID card — REAL ID or not — will not work. You must have a U.S. passport book or passport card. Some countries also accept an enhanced driver's license for land and sea travel to Canada, Mexico, and the Caribbean, but air travel requires a passport.

Passport cards are valid for international travel by air and cost less than a passport book, though they have a smaller format and some travelers prefer the book. Both are issued by the U.S. Department of State and take the same amount of time to obtain.

Planning Ahead: Which Document to Get

If you fly regularly and do not have a passport, a passport card is often the most practical choice. It costs less than a passport book, fits in a wallet, and works for all domestic flights plus international travel by air. The main drawback is that some countries require a passport book rather than a card, so check your destination before you decide.

If you travel internationally often or to countries that do not accept passport cards, a passport book is worth the extra cost. If you have a military ID or tribal ID, you already have a valid travel document and do not need to get anything else for domestic flights.

If your flight is coming up soon and you have no ID, contact TSA before you go to the airport. They can tell you whether your specific situation qualifies for secondary screening or whether you should reschedule.

Frequently Asked Questions

Can I fly with just a photo of my ID on my phone?

No. TSA requires a physical document, not a digital copy. The officer needs to see and inspect the actual card or passport. A photo on your phone will not work at the checkpoint.

Will I be denied boarding if I show up without any ID?

No, you will not be denied. You will go through secondary screening instead, which takes longer. However, TSA must be able to verify your identity through their questions and background checks. If they cannot verify who you are, then you may not be allowed to board.

How much does a passport card cost?

A passport card for an adult costs $35 for a new card or $30 for a renewal, plus a $35 execution fee if you explore in person. Expedited processing adds $60. Prices can vary slightly, so check the U.S. Department of State website for current fees.

Can I use my birth certificate to fly?

No. A birth certificate alone is not on the TSA's list of acceptable documents. However, a birth certificate plus a photo ID issued by a state or local government can sometimes be used together for domestic flights if you have no other option — ask TSA at the checkpoint.

Do I need a REAL ID card if I have a passport?

No. A passport works for flying and for entering federal buildings. You do not need a REAL ID card if you have a passport. The REAL ID rule applies mainly to people who want to use a state ID card for federal purposes.
