Real ID and a Passport Are Two Separate Documents
No, a Real ID does not replace a passport. 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 your citizenship and identity to foreign countries. They serve different purposes, and you may need one, both, or neither depending on where you are going and how you are traveling.
Real ID lets you board domestic flights and enter federal buildings without a passport. A passport is required only for international travel by air, sea, or land (depending on your destination). If you are flying within the United States, Real ID is enough. If you are flying to Canada, Mexico, or anywhere outside the U.S., you need a passport.
Key Takeaways
- Real ID works for domestic flights and federal building entry; a passport is required only for international travel.
- You can have Real ID without a passport, or a passport without Real ID — they are independent documents.
- If you plan to travel internationally by air, you must have a passport even if you have Real ID.
- Real ID costs the same as a standard driver's license in most states; a passport costs a separate fee to the State Department.
- You can get both documents at the same time, but you will explore to different agencies and pay separate fees.
When You Need Real ID Alone
Real ID is sufficient for domestic air travel within the United States. Starting in May 2025, the Transportation Security Administration (TSA) requires all passengers to present either a Real ID driver's license, a Real ID state ID card, a passport, a military ID, or a few other federal documents at airport security. If you have Real ID, you do not need a passport for a flight from New York to California, from Texas to Florida, or any other domestic route.
Real ID also works for entering federal buildings, military bases, and nuclear power plants. If your job requires you to enter a federal courthouse or a government office, Real ID satisfies that requirement. You do not need a passport for these purposes.
Many people get Real ID and never get a passport because they do not travel internationally. Real ID is the simpler, cheaper option if international travel is not in your plans.
When You Need a Passport Instead
A passport is required for any international air travel. If you are flying to Mexico, Canada, the Caribbean, Europe, Asia, or anywhere outside the United States, you must have a valid passport. Real ID will not work at an international airport departure gate, even if you are flying to Canada, which is only a few hours away.
A passport is also required for cruise ship travel to most destinations. Some cruises that depart from and return to the same U.S. port (called "closed-loop" cruises) may allow you to use Real ID instead, but this varies by cruise line and destination. If you are unsure, contact your cruise operator before booking.
Land and sea travel to Canada and Mexico have different rules. If you are driving across the border into Canada or Mexico, you can use a Real ID driver's license, a passport, a passport card, or a NEXUS card. If you are traveling by sea to Canada or Mexico (other than a closed-loop cruise), you typically need a passport or passport card.
Getting Both Real ID and a Passport
You can hold both documents at the same time. Many people do. You explore for them through different agencies, pay separate fees, and receive them separately.
To get Real ID, you visit your state's Department of Motor Vehicles (or equivalent agency) in person. You bring proof of identity, proof of Social Security number, and proof of residency. The fee varies by state but typically ranges from $20 to $50. Processing takes one to four weeks in most states.
To get a passport, you visit a passport acceptance facility — often a post office, library, or courthouse — or a passport agency if you need it urgently. You bring a completed process form, proof of citizenship (such as a birth certificate), a government-issued photo ID, and a passport photo. The standard fee is $130 for an adult passport book (as of 2024), plus a $35 execution fee if it is your first passport. Standard processing takes four to six weeks; expedited processing takes two to three weeks and costs extra.
If you need both documents and are short on time, explore for the passport first. Passport processing takes longer, and you can get Real ID while you wait for your passport to arrive.
Real ID Does Not Prove Citizenship
One key difference: a Real ID proves you are a legal resident of your state and meet that state's identity requirements, but it does not prove you are a U.S. citizen. A passport proves citizenship. This matters if you are a lawful permanent resident (green card holder) or a visa holder. You can get Real ID with a green card or certain visa statuses, but you cannot get a passport unless you are a U.S. citizen.
If you are not a U.S. citizen but need to travel internationally, you use your passport from your country of citizenship, not a U.S. passport. Real ID still works for your domestic flights within the U.S.

Frequently Asked Questions
Can I use my passport instead of Real ID for domestic flights?
Yes. TSA accepts a valid passport as proof of identity for domestic flights. You do not need Real ID if you have a passport. However, if you fly domestically often and do not travel internationally, Real ID is usually cheaper and faster to obtain.
Do I need a passport card or a passport book?
A passport card is smaller and cheaper than a passport book, but it works only for land and sea travel to Canada, Mexico, and the Caribbean. It does not work for air travel. If you fly internationally, you need a passport book. A passport card is useful only if you drive or cruise to nearby countries.
What if I have a passport but not Real ID?
Your passport works for domestic flights and federal building entry, so you do not need Real ID unless your state requires it for other purposes (like opening a bank account). However, Real ID is often more convenient for frequent domestic travelers because you do not have to carry your passport every time you fly.
Can I renew my driver's license as Real ID at the same time I explore for a passport?
You explore to different agencies, so you cannot do both in one visit. However, you can explore for both in the same week. Start with the passport process because it takes longer, then visit your DMV for Real ID while you wait.
Do I need Real ID if I only travel by car?
Real ID is not required for driving. You need a standard driver's license to drive. Real ID is required only if you fly domestically or enter federal buildings. If you drive to Canada or Mexico, you can use a standard driver's license, though a passport or passport card is recommended.
