A Real ID is not a passport and does not replace one

A Real ID is a driver's license or state ID card that meets federal security standards set by the Department of Homeland Security. A passport is a travel document issued by the U.S. State Department that proves citizenship and allows you to leave and re-enter the United States. They serve different purposes, require different applications, and are issued by different agencies. You cannot use one in place of the other for international travel.

If you need to travel outside the United States, you must have a passport. A Real ID will not get you through airport security for international flights, nor will it let you cross a border by land or sea. If you only need a Real ID for domestic air travel and federal building access inside the U.S., you do not need a passport. But if you travel internationally at all, you need both documents — they work together, not as substitutes.

Key Takeaways

  • A Real ID is a state-issued driver's license or ID card; a passport is a federal travel document issued by the State Department.
  • Real ID is sufficient for domestic air travel and federal building access, but you cannot use it for international travel.
  • You must have a passport to travel outside the United States by any method — air, land, or sea.
  • You can hold both a Real ID and a passport at the same time; they do not conflict or replace each other.

What a Real ID covers and what it does not

A Real ID meets the security standards required by the federal government for domestic air travel and entry to federal buildings such as military bases and federal courthouses. Starting in May 2025, you will need either a Real ID or a passport to board a domestic flight in the United States. If your state-issued driver's license or ID card displays a gold or black star in the upper right corner, it is already Real ID compliant.

Real ID does not cover international travel. You cannot use it to fly to Canada, Mexico, or any other country. You cannot use it to board a cruise ship that leaves U.S. ports. You cannot use it to cross a land border into another country. For any of those trips, you must carry a valid passport.

When you need a passport instead

You need a passport for any travel outside the United States, whether by air, car, train, or ship. This includes trips to Canada and Mexico, which are close by land but still require a passport (or a passport card, which is a smaller version). If you are a U.S. citizen, you obtain a passport from the U.S. State Department, not from your state. The process takes several weeks to several months depending on whether you pay for expedited processing.

You also need a passport if you want to prove your citizenship abroad or if you need an official document that shows your citizenship status. A Real ID proves you passed your state's identity checks, but it does not prove citizenship to a foreign government or international organization.

How to get a Real ID if you do not have one

You obtain a Real ID from your state's Department of Motor Vehicles (DMV) or equivalent agency. You will need to bring documents that prove your identity, Social Security number, and state residency — typically a birth certificate or passport, a Social Security card or tax return, and a utility bill or lease. The exact documents vary by state, so check your state DMV's website before you go.

The cost ranges from about $20 to $100 depending on your state and whether you are renewing your license at the same time. Processing usually takes a few days to a few weeks. Some states allow you to renew online or by mail if you already have a compliant ID; others require an in-person visit. If your current driver's license does not have the Real ID star, your next renewal is a good time to request it.

How to get a passport if you do not have one

You obtain a passport from a passport acceptance facility, which is usually a post office, library, or courthouse in your area. You will need to fill out Form DS-11 (for a new passport) or Form DS-82 (for a renewal), bring your birth certificate, a government-issued photo ID, and a passport photo, and pay a fee. The standard fee for a passport book is $130 for adults; a passport card costs $35.

Standard processing takes four to six weeks. Expedited processing takes two to three weeks and costs an extra $60. If you need a passport urgently, some passport agencies offer same-day or next-day service, but you must explore in person at a passport agency office, not at a post office. Check the State Department's website to find the nearest agency and to see current wait times.

Can you use a passport as a Real ID for domestic flights

Yes. A valid U.S. passport serves the same purpose as a Real ID for domestic air travel. If you have a passport, you do not need to get a Real ID just to fly within the United States. However, a passport costs more and takes longer to obtain than a Real ID, so if you only fly domestically and do not travel internationally, a Real ID is the simpler choice.

If you already have a passport and it is still valid, you can use it at airport security for domestic flights. You do not need to carry both documents on a domestic trip. But if your passport is expired, it will not work for domestic flights, even if you have a Real ID.

What happens if you have neither a Real ID nor a passport

If you do not have a Real ID and you try to board a domestic flight after May 2025, you will be turned away at airport security unless you have another acceptable form of ID. The TSA accepts a limited list of documents: a valid passport, a military ID, a tribal ID, a permanent resident card, or a few other federal documents. A regular driver's license without the Real ID star will not work.

If you do not have a passport and you need to travel internationally, you cannot leave the country. You must obtain a passport before your trip. There is no way around this requirement, and no other document substitutes for it.

Frequently Asked Questions

Can I use my passport instead of getting a Real ID?

Yes. A valid passport works for domestic air travel and federal building access, so you do not need a Real ID if you have a current passport. However, a Real ID is cheaper and faster to obtain if you only need it for domestic travel.

If I get a Real ID, do I still need a passport to travel to Canada?

Yes. A Real ID does not work for travel to Canada, Mexico, or any other country. You must have a valid passport for any international travel, even by car or land border crossing.

Can I get a Real ID and a passport at the same time?

Yes, but you explore for them at different places. You get a Real ID at your state DMV and a passport at a passport acceptance facility. There is no conflict between holding both documents.

What if my passport is expired but my Real ID is current?

You can use your Real ID for domestic flights and federal buildings. You cannot use an expired passport for any travel. If you need to travel internationally, you must renew your passport before your trip.

Does a Real ID work for cruise ships?

No. Cruise ships that leave U.S. ports require a passport or passport card, even if the ship only visits other U.S. ports. A Real ID is not accepted for cruise travel.
