Valid ID Requirements for Domestic Flights
To board a domestic flight in the United States, you need one form of government-issued photo ID. The Transportation Security Administration (TSA) accepts a driver's license, state ID card, passport, passport card, military ID, or tribal ID. If your ID is expired, TSA will still accept it for domestic travel — there is no expiration date requirement for flying within the country.
You do not need a Real ID-compliant driver's license for domestic flights. A standard state driver's license works fine. Real ID compliance matters only if you want to use a driver's license to enter a federal building or military base, not for air travel.
The ID must match the name on your airline ticket. If your name has changed since your ID was issued — through marriage, divorce, or legal name change — bring a document that shows both names, such as a marriage certificate or court order. The airline will check this before you board.
Key Takeaways
- A standard state driver's license or passport is the most common ID accepted for domestic flights, and expired IDs are still valid.
- Your ID name must match your airline ticket name, and you should bring proof of a legal name change if they differ.
- TSA does not require Real ID-compliant licenses for domestic air travel, only for federal building entry.
- If you do not have a photo ID, you can request secondary verification at the airport, though this takes extra time.
- International flights require a valid passport or passport card, not a driver's license.
What Counts as Valid Photo ID
TSA maintains a list of documents it accepts at security checkpoints. For domestic flights, these include a driver's license from any U.S. state or territory, a state-issued ID card, a U.S. passport or passport card, a military ID, a tribal ID issued by a federally recognized tribe, and an Enhanced Driver's License (EDL) issued by certain states.
Less common but still valid options include a merchant mariner credential, a NEXUS card, a SENTRI card, or a FAST card — these are typically held by people who cross borders regularly for work. If you hold one of these, it will work at TSA checkpoints.
Your ID does not have to be from your home state. If you have moved and your driver's license is from another state, that is fine. TSA does not care where the ID was issued, only that it is government-issued and has your photo on it.
Flying Without a Standard Photo ID
If you arrive at the airport without any photo ID, you can still fly, but the process takes longer. TSA will ask you to complete a form and answer questions to verify your identity — they may ask about your address history, previous addresses, or other personal details. This secondary verification usually adds 15 to 30 minutes to your security screening.
Bring any documents that help prove who you are, even if they do not have a photo. A birth certificate, Social Security card, bank statement, utility bill, or insurance card can support your identity claim. The more documents you bring, the faster the process typically moves.
Some travelers — such as people with certain disabilities or those experiencing homelessness — may have legitimate reasons for not carrying standard ID. TSA has procedures for these situations, but you should arrive extra early and be prepared to explain your circumstances to a supervisor.
International Flights and Passport Requirements
For flights leaving the United States to another country, you need a valid U.S. passport or passport card. A driver's license will not work. Your passport must not be expired, and some countries require that it remain valid for at least six months after your travel dates, so check your destination's entry requirements before you book.
If you do not yet have a passport, you can obtain one through your local post office, courthouse, or passport acceptance facility. Processing times vary — routine service takes several weeks, and expedited service costs extra but is faster. Plan ahead, especially during peak travel seasons.
A passport card is smaller and cheaper than a passport book, but it works only for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. For flights to other countries, you need the full passport book.
Name Mismatches Between ID and Ticket
Your airline ticket name must match your ID exactly. If your ticket says "Robert James Smith" but your driver's license says "Bob Smith," you may be stopped at security. The airline's computer system flags mismatches, and TSA will ask you to explain the difference.
If your name has changed legally, bring the document that proves it — a marriage certificate, divorce decree, or court order for a legal name change. These documents do not need to be originals; a certified copy or even a clear photocopy usually works. Keep this document with your ID when you travel.
If you have recently changed your name but have not yet renewed your ID, book your ticket under the name on your current ID. Then bring your marriage certificate or court order to the airport to show TSA. This is faster than trying to change your ticket after booking.
Real ID and Domestic Air Travel
Real ID is a federal security standard that applies to driver's licenses and state ID cards. Starting in May 2025, TSA will require a Real ID-compliant license or another acceptable form of ID for domestic flights. However, this does not mean you need to get a new license — any of the other documents on TSA's accepted list (passport, military ID, tribal ID) will still work.
If you want to upgrade your driver's license to Real ID compliance, you can do so at your state's DMV. You will need to bring proof of identity, proof of citizenship, and proof of your current address. The process is straightforward but takes time, so do not wait until the last minute if you want to switch.
Many states have already issued Real ID-compliant licenses to new applicants, so your current license may already meet the standard. Check your state's DMV website or look at your license — a small star in the upper right corner indicates Real ID compliance.
TSA PreCheck and ID Requirements
If you have TSA PreCheck, you still need to show a valid photo ID at security, just like any other traveler. TSA PreCheck does not waive the ID requirement — it speeds up the screening process by allowing you to keep shoes, belts, and light jackets on, and to leave laptops and liquids in your bag.
To enroll in TSA PreCheck, you must provide a valid government-issued photo ID during the process process. Once enrolled, you use your Known Traveler Number (KTN) when booking flights, and TSA will recognize you at security checkpoints.
Frequently Asked Questions
Can I use an expired ID to fly domestically?
Yes. TSA accepts expired driver's licenses and state ID cards for domestic flights. There is no expiration date requirement. However, your ID must still be government-issued and have your photo on it.
What if my name on my ID does not match my airline ticket?
Bring a document proving the name change, such as a marriage certificate or court order. Show both your ID and this document to TSA. If you have not updated your ID yet, book your ticket under the name on your current ID and bring the proof of change to the airport.
Do I need a Real ID license to fly domestically after May 2025?
No. You need either a Real ID-compliant license or another form of TSA-accepted ID, such as a passport, military ID, or tribal ID. A standard driver's license will no longer work alone, but you have other options.
Can I fly with just a passport card?
Yes, a passport card is valid for domestic flights. However, it works for international flights only to Canada, Mexico, Bermuda, and the Caribbean — not to other countries. For most international travel, you need a full passport book.
What happens if I show up at the airport without any ID?
TSA will ask you to complete a form and answer identity verification questions. This process takes longer — usually 15 to 30 minutes — but you can still fly. Bring any supporting documents, such as a birth certificate or utility bill, to speed up the process.
