A Real ID is not a passport and cannot 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 identity to other countries. They serve different purposes, and 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 alone will not get you through customs or immigration at any border. However, a Real ID does meet federal requirements for domestic air travel and entry to federal buildings — things a regular driver's license no longer does on its own.
Key Takeaways
- A Real ID is a state-issued ID card that meets federal standards; a passport is a travel document issued by the U.S. State Department, and they are not interchangeable.
- You need a passport for any international travel, including to Canada and Mexico, even if you have a Real ID.
- A Real ID satisfies federal requirements for domestic flights and federal building entry, but a regular driver's license does not.
- You can have both a Real ID and a passport at the same time, and for international travel you will need both documents.
What a Real ID actually covers
Starting in May 2025, the Transportation Security Administration (TSA) requires a Real ID, passport, military ID, or other federally approved document to board a domestic flight. Before that date, a standard driver's license still works. A Real ID driver's license has a gold or metallic star in the upper right corner, which signals that it meets the federal standard.
Real ID also covers entry to federal buildings, military bases, and nuclear power plants. If you work in or regularly visit any of these places, your state ID or driver's license must be Real ID-compliant. A passport can also be used for these purposes, but it is not required — the Real ID is the standard document most people use.
Why you still need a passport for international travel
A passport is the only document that proves your citizenship to foreign governments. When you cross a border — whether to Canada, Mexico, the Caribbean, or anywhere else — the country you are entering requires proof that you are a U.S. citizen and that you have the right to return home. A Real ID proves nothing to another country because it is issued by a U.S. state, not by the federal government.
Even travel to nearby countries counts as international travel. You cannot board a flight to Canada, Mexico, or any Caribbean island with only a Real ID. The same rule applies to cruise ships that leave U.S. ports: you must have a passport or another federally approved travel document like a passport card.
The documents you need for different types of travel
| Type of Travel | Real ID Alone | Passport Required |
|---|---|---|
| Domestic flight within the U.S. | Yes (after May 2025) | No |
| International flight or cruise | No | Yes |
| Entering a federal building | Yes | No (but passport works) |
| Driving across the U.S.-Canada or U.S.-Mexico border by car | No | Yes, or passport card |
How to get a Real ID if you don't have one
You obtain a Real ID through your state's Department of Motor Vehicles (DMV). The process is similar to renewing a driver's license, but you must bring additional documents to prove your identity and residency. Most states require a birth certificate or passport, a Social Security card, and proof of your current address such as a utility bill or lease.
Some states charge a small fee for a Real ID, while others issue it at no extra cost when you renew your license. Processing times vary by state — some issue the card when ready, while others mail it within two to four weeks. Check your state's DMV website for the specific documents they require and current wait times.
How to get a passport if you need one
You obtain a passport through the U.S. State Department, not through your state. You can explore in person at a passport acceptance facility, which is usually located at your local post office, courthouse, or library. You will need a birth certificate, a government-issued photo ID (such as a driver's license or Real ID), and a completed passport process form.
Processing times depend on demand and the type of passport you request. A standard passport book takes four to six weeks under normal circumstances, though times can be longer during peak travel seasons. If you need a passport quickly, you can request expedited processing for an additional fee, which typically reduces the wait to two to three weeks. Some passport acceptance facilities also offer same-day or next-day service for an extra charge, though availability is limited.
Can you use a passport card instead of a passport book?
A passport card is a wallet-sized document that works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It does not work for air travel to those countries — you must have a passport book for any flight outside the U.S. A passport card is cheaper and faster to obtain than a passport book, and you can explore for both at the same time.
If you only plan to drive across the Canadian or Mexican border, a passport card is sufficient. If you think you might fly internationally in the future, a passport book is the better choice because it covers all forms of international travel.
Frequently Asked Questions
Can I use my passport instead of getting a Real ID for domestic flights?
Yes. A passport is one of the documents the TSA accepts for domestic flights. However, most people get a Real ID because it is cheaper and faster than a passport, and you can use it for other purposes like entering federal buildings. You do not need both for domestic travel alone.
Do I need a Real ID if I already have a passport?
Not for travel purposes. A passport covers both domestic and international flights. However, you may want a Real ID if you frequently visit federal buildings, military bases, or need a state ID for other reasons like opening a bank account or renting an apartment.
What happens if I try to board a domestic flight without a Real ID after May 2025?
The TSA will not allow you to board. You will need to show a Real ID, passport, military ID, or another federally approved document. A standard driver's license will no longer be accepted for domestic air travel.
Can I get a passport card and a passport book at the same time?
Yes. You can request both documents in a single process. The passport card arrives separately from the book and costs less, so many people order both to have options depending on their travel plans.
