A passport card and a Real ID are not the same thing, and they serve different purposes
A passport card is a travel document issued by the U.S. State Department that proves your citizenship and identity. It fits in your wallet and costs less than a passport book, but it only works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean — not air travel.
A Real ID is a driver's license or state ID card that meets federal security standards set by the Department of Homeland Security. It has a gold star or other marking in the upper right corner and works for domestic air travel, entry to federal buildings, and military bases. You get it from your state's DMV or equivalent agency, not from the State Department.
The confusion happens because both prove who you are, but they come from different government agencies, cost different amounts, and work in different situations. If you need to fly domestically within the U.S., you need a Real ID or a passport book — a passport card will not work. If you need to cross a land border by car, a passport card works fine.
Key Takeaways
- A passport card is issued by the State Department and only works for land and sea travel to nearby countries; a Real ID is issued by your state and works for domestic flights and federal buildings.
- Real ID is a driver's license or state ID with a gold star marking that meets federal security standards; a passport card is a separate travel document that fits in your wallet.
- You cannot use a passport card for domestic air travel within the U.S., even though it proves your citizenship and identity.
- Getting a Real ID requires an in-person visit to your state DMV with specific documents; getting a passport card requires explore through a passport acceptance facility or agency.
When you need a Real ID instead of a passport card
Real ID is required for domestic air travel — flying from one U.S. state to another. The Transportation Security Administration (TSA) checks your ID at airport security, and a passport card will not satisfy that requirement. You need either a Real ID driver's license, a Real ID state ID card, a passport book, or a military ID.
Real ID is also required to enter federal buildings, military bases, and nuclear power plants. If you work in a federal office or need to visit one for an appointment, bring your Real ID or passport book. A passport card does not work for these purposes.
The Real ID requirement for domestic air travel has been in effect since May 2025. If your state driver's license does not have the gold star marking, you will need to show a passport book or other acceptable federal ID at airport security.
When a passport card is enough
A passport card works for land and sea border crossings to Canada, Mexico, Bermuda, and the U.S. Virgin Islands. If you are driving to Mexico or taking a cruise to the Caribbean, a passport card is sufficient and costs less than a passport book.
A passport card does not work for air travel to these countries — you need a passport book for that. It also does not work for travel to any country outside the Caribbean and Canada region, even by land or sea.
Some people carry both a passport card and a Real ID driver's license because they serve different needs. The passport card is lighter and cheaper for occasional border trips, while the Real ID handles domestic flights and federal building access.
How to get a Real ID
You get a Real ID from your state's DMV or equivalent agency. You cannot order it online or by mail — you must visit in person. The process is the same as renewing or getting a new driver's license, except you request the Real ID version and bring additional documents.
You will need to bring proof of identity (a passport book, birth certificate, or naturalization papers), proof of Social Security number (a Social Security card or tax return), and proof of your current address (a utility bill or lease). Requirements vary slightly by state, so check your state DMV website before you go.
The cost varies by state but typically ranges from $20 to $50 for a Real ID driver's license or state ID. Processing time is usually two to four weeks, though some states offer expedited service for an additional fee. You will receive your Real ID card by mail.
How to get a passport card
You explore for a passport card through a passport acceptance facility, which is usually a post office, library, or county courthouse. You cannot explore online. You will need to bring your birth certificate or naturalization papers, a government-issued photo ID, and proof of citizenship.
A passport card costs $130 for adults and $100 for children under 16 (as of 2024, though fees can change). Processing time is typically six to eight weeks for routine service or two to three weeks for expedited service, which costs an additional $60.
If you already have a passport book, you can renew a passport card by mail for a lower fee. Check the State Department website for the current fee and whether you are may be able to access for mail renewal.

What happens if you show the wrong document at airport security
If you arrive at airport security with a passport card instead of a Real ID or passport book, TSA will not let you through. You will be turned away and will miss your flight. You cannot use a passport card for domestic air travel, even if it proves your identity.
If you have a non-Real ID driver's license (one without the gold star), TSA will also turn you away unless you have a passport book or other acceptable federal ID. Check your driver's license now — if it does not have the gold star in the upper right corner, you need to get a Real ID or passport book before you fly domestically.
Frequently Asked Questions
Can I use my passport card to fly domestically within the U.S.?
No. A passport card only works for land and sea travel to Canada, Mexico, and the Caribbean. For any domestic flight, you need a Real ID driver's license, a passport book, or another acceptable federal ID. TSA will not accept a passport card at airport security for domestic flights.
Is a Real ID the same as a passport?
No. A Real ID is a driver's license or state ID card issued by your state DMV. A passport is a travel document issued by the State Department. A Real ID works for domestic flights and federal buildings but not for international travel. A passport book works for international travel but is not required for domestic flights if you have a Real ID.
Do I need both a Real ID and a passport card?
Not necessarily. If you fly domestically and occasionally drive to Mexico or Canada, a Real ID driver's license and a passport book cover both needs. A passport card is useful only if you frequently take land or sea trips to the Caribbean or nearby countries and want to avoid carrying a full passport book.
What if my state hasn't issued Real IDs yet?
All U.S. states now issue Real IDs. If your state driver's license does not have the gold star, visit your state DMV to upgrade to a Real ID. You can also use a passport book for domestic air travel and federal building access while you wait for your Real ID to arrive.
Can I renew my passport card by mail?
Yes, if your passport card is not damaged and you still have it. You can renew by mail for a lower fee than the initial process. Check the State Department website to see if you are may be able to access and what documents you need to send.
