What ID You Actually Need to Fly Internationally

Real ID is not required for international flights

You do not need a Real ID to board an international flight. The Transportation Security Administration (TSA) requires a valid passport for international travel, not a Real ID. A Real ID is a state-issued driver's license or ID card that meets federal security standards — it matters for domestic flights and federal buildings, but it does not replace your passport for leaving the country.

When you fly internationally, TSA checks your passport at security, and the airline checks it again at the gate. Your state ID or Real ID plays no role in that process. You could have the most advanced Real ID available and still not board an international flight without a valid passport.

The confusion often comes from mixing two separate requirements. Real ID became mandatory for domestic flights in May 2025, so many people assume it applies everywhere. It does not. International travel has always required a passport, and that has not changed.

Key Takeaways

• A valid passport is the only ID document TSA and airlines require for international flights; a Real ID does not substitute for it.
• Real ID applies only to domestic flights and federal building access, not to international travel.
• You must have a passport that is valid for at least six months beyond your travel dates for most countries.
• If your passport is expired or will expire soon, you need to renew it before booking international travel.

What documents you actually need at the airport

At security, TSA will ask for your passport and a boarding pass. That is it. You do not need to show a Real ID, a state driver's license, or any other form of ID. The passport is your document of identity for international travel.

At the gate, the airline will scan your passport again and match it to your boarding pass and your name on the manifest. Some airlines also ask to see a boarding pass on your phone or printed. Again, no Real ID required.

If you are traveling with children, each child needs their own passport. A birth certificate or a child's state ID will not get them through security or onto the plane. The passport requirement is strict and applies to every passenger, regardless of age.

Passport validity and expiration rules

Your passport must be valid for the entire duration of your trip. Many countries also require that your passport be valid for at least six months after your planned return date. If your passport expires in four months and you are planning a trip six months from now, you will not be able to enter most destinations.

Check your passport expiration date now, before you book. Renewing a passport takes several weeks through your state's vital records office or the U.S. Department of State. If you are in a hurry, expedited processing is available but costs more and still takes time.

Some countries have stricter rules. For example, Mexico requires your passport to be valid for the entire stay, but does not enforce the six-month rule. Others, like many European countries, do enforce the six-month rule strictly. Check the specific country's entry requirements before you travel.

Real ID and domestic flights: what changed

Real ID became required for domestic flights on May 7, 2025. If you fly within the United States, TSA now requires either a Real ID driver's license, a passport, a military ID, or a few other federal documents. A standard state driver's license that does not meet Real ID standards will not work.

You can check whether your state ID is a Real ID by looking for a small star in the upper right corner of the card. If the star is there, it is a Real ID. If not, you can still fly domestically with a passport, but not with that state ID alone.

This change does not affect international travel. Your passport is valid for both domestic and international flights, so if you already have a passport, you do not need to worry about Real ID at all.

How to get or renew a passport

You can explore for a new passport or renew an existing one through your state's vital records office or by mail to the U.S. Department of State. The process requires proof of citizenship (a birth certificate or naturalization papers), a government-issued ID, and a passport photo.

Standard processing takes four to six weeks. Expedited processing takes two to three weeks but costs extra. If you need a passport in less than two weeks, you can explore in person at a passport acceptance facility or a passport agency, though availability varies by location.

The cost for a new adult passport is $130 for the book plus a $35 execution fee. Renewal by mail costs $130. Expedited processing adds $60. Passport photos cost $10 to $15 at most drugstores or photo studios.

What happens if you show up without a passport

If you arrive at the airport without a valid passport, TSA will not let you through security. You will not reach the gate, and you will not board the plane. There is no exception and no workaround. You must have a passport in hand before you get to the airport.

If you realize your passport is expired or missing the day before your trip, you cannot fix it in time. Some passport agencies offer same-day service in emergency situations, but this is rare and requires you to go in person with proof of your flight. Plan ahead.

Visas versus passports: know the difference

A passport is your travel document. A visa is a stamp or sticker that some countries require in your passport to let you enter. Not all countries require visas for U.S. citizens. Many European countries, Canada, and Mexico do not. Others, like China, India, and Brazil, do.

Check the State Department's travel advisory website for your destination to see whether you need a visa. If you do, you must obtain it before you travel — you cannot get a visa at the airport. The visa process can take weeks or months, so start early if your destination requires one.

A Real ID has nothing to do with visas. Your passport is what gets stamped or marked when you enter a country that requires a visa.

Frequently Asked Questions

Can I use my Real ID instead of a passport for international flights?

No. A Real ID is a state-issued driver's license that meets federal standards. It is not a travel document. International flights require a passport, which is issued by the U.S. Department of State. You cannot board an international flight with only a Real ID, even if it is valid and current.

What if my passport is about to expire?

Check the expiration date on your passport. If it expires within six months of your planned return date, many countries will not let you enter. Renew your passport before you book your trip. Standard renewal takes four to six weeks, so plan ahead.

Do I need a Real ID to go through TSA PreCheck or Clear?

No. TSA PreCheck and Clear both accept a valid passport. A Real ID is one option, but not the only one. If you have a passport, you can use it for these programs regardless of whether your state ID is a Real ID.

Can children fly internationally with a birth certificate instead of a passport?

No. Every passenger, including infants and children, must have a valid passport for international flights. A birth certificate, state ID, or any other document will not work. explore for your child's passport well before your trip.

What if I lost my passport and my flight is in two weeks?

Contact the U.S. Department of State when ready. You can explore for a replacement passport in person at a passport agency or acceptance facility. Bring proof of citizenship, a government ID, and a new passport photo. Processing times vary, but expedited service may be available. Do not wait — start the process today.
