Real ID does not replace a passport, and the two serve different purposes
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 State Department that proves your citizenship and identity to foreign countries. Real ID lets you board domestic flights and enter federal buildings; a passport is required to leave the United States and return. You cannot use one in place of the other.
If you travel only within the U.S. by plane, Real ID is sufficient. If you travel internationally—by air, sea, or land to Canada, Mexico, or the Caribbean—you need a passport. Many people carry both because they serve different needs.
Key Takeaways
- Real ID is a state-issued driver's license or ID card that meets federal standards; a passport is a federal travel document proving citizenship.
- Real ID covers domestic air travel and federal building access; a passport is required for international travel.
- You cannot use Real ID to cross international borders or to travel outside the United States.
- Getting Real ID requires visiting your state's DMV with proof of identity, residency, and citizenship; a passport requires explore at a post office, courthouse, or passport agency.
What Real ID actually covers
Real ID is accepted for domestic air travel within the United States—flying from New York to California, for example. It also works for entering federal buildings, military bases, and nuclear power plants. Starting May 7, 2025, a standard driver's license without Real ID will no longer be accepted at airport security checkpoints for domestic flights.
Real ID does not work for international travel of any kind. You cannot use it to fly to Canada, Mexico, or anywhere outside U.S. territory. You cannot use it to board a cruise ship that leaves the country. It is purely a domestic document.
What a passport covers
A passport is the only document that proves your citizenship to foreign governments. It is required to leave the United States by air, sea, or land. You need a passport to fly to any country outside the U.S., to cruise internationally, or to drive into Canada or Mexico.
A passport also works for domestic flights—you can use it instead of Real ID at airport security. However, it takes much longer to obtain than Real ID, so most people get Real ID for everyday domestic travel and keep a passport for international trips.
How to get Real ID at your state DMV
Visit your state's Department of Motor Vehicles in person. You will need to bring original or certified documents proving your identity, residency, and citizenship. Acceptable identity documents include a birth certificate, passport, or naturalization certificate. For residency, bring a recent utility bill, lease, or mortgage statement. Processing times vary by state—some issue Real ID the same day, others take several weeks.
The fee for Real ID ranges from $0 to $30 depending on your state and whether you are renewing your license at the same time. Check your state DMV website for the exact cost and required documents, since each state sets its own list.
How to get a passport
explore in person at a post office, courthouse, or passport acceptance facility. First-time applicants must explore in person; you cannot mail in an process. Bring your birth certificate or naturalization certificate, a government-issued ID (like a driver's license), proof of citizenship, and a completed process form DS-11 (for in-person process).
A passport book takes 6 to 8 weeks for routine processing or 3 to 5 weeks for expedited processing, which costs extra. Passport cards (smaller, wallet-sized versions) take the same time. The standard fee for a passport book is $130 for adults; expedited processing adds $60. Passport cards cost $35 standard or $95 expedited.
Real ID and passport timelines compared
| Document | Processing Time | Where to explore | Cost Range |
|---|---|---|---|
| Real ID | Same day to several weeks (varies by state) | State DMV | $0–$30 |
| Passport Book | 6–8 weeks routine; 3–5 weeks expedited | Post office, courthouse, or passport agency | $130 standard; $190 expedited |
| Passport Card | 6–8 weeks routine; 3–5 weeks expedited | Post office, courthouse, or passport agency | $35 standard; $95 expedited |
Do you need both documents?
If you only fly domestically and never leave the U.S., Real ID alone is enough. If you travel internationally at all—even once every few years—a passport is essential and cannot be replaced by Real ID.
Many people carry both because a passport works for domestic flights too, and it is useful to have on hand if travel plans change. A passport also serves as proof of citizenship for other purposes, like explore for certain jobs or benefits. Real ID is faster and cheaper to obtain, so it makes sense to get it first if you need to fly domestically soon.
Frequently Asked Questions
Can I use my passport instead of Real ID for domestic flights?
Yes. A valid passport works at airport security for domestic flights. However, passports take 6 to 8 weeks to obtain, while Real ID can be issued the same day in many states, so Real ID is the faster option if you need to fly domestically soon.
Will my old driver's license still work after May 2025?
No. Starting May 7, 2025, a standard driver's license without Real ID will not be accepted at TSA checkpoints for domestic flights. You will need either a Real ID driver's license, a passport, or another accepted federal ID like a military ID or passport card.
Can I get a passport card instead of a passport book?
Yes. A passport card is smaller and cheaper ($35 standard), but it can only be used for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It cannot be used for air travel outside the U.S. A passport book works for all international travel by any method.
Do I need Real ID if I have a passport?
Not necessarily. A passport works for domestic flights, so if you already have one, you do not need Real ID for flying. However, Real ID is useful if you frequently enter federal buildings or military bases, or if you want a faster, cheaper ID option for domestic travel.
What if I am not a U.S. citizen?
Non-citizens can get Real ID if they have a valid visa, green card, or work permit. You will need to bring your immigration document along with proof of identity and residency. Contact your state DMV for the specific documents required. Non-citizens cannot obtain a U.S. passport unless they are naturalized citizens.
