What a passport card and Real ID are, and why they're different
A passport card is a wallet-sized travel document issued by the U.S. State Department. It proves your citizenship and identity, and you can use it to enter Canada, Mexico, Bermuda, and the Caribbean by land or sea — but not by air. It costs less than a passport book and takes up less space, but it has real limits on where you can go.
A Real ID is not a separate document. It is a security standard that your driver's license or state ID must meet. Real ID-compliant licenses have a small star or marking in the upper right corner. You need one to board a domestic flight, enter a federal building, or visit a military base. Most states now issue Real ID-compliant licenses automatically, but some people still have the older version.
The confusion happens because both are forms of identification, and both involve the federal government. But they serve completely different purposes. A passport card gets you across borders. A Real ID-compliant license gets you through airport security for flights within the United States.
Key Takeaways
- A passport card is for international travel to nearby countries by land or sea; a Real ID is for domestic flights and federal building access.
- You cannot use a passport card to board a domestic airplane — you need either a Real ID-compliant driver's license, a passport book, or a military ID.
- Most states now issue Real ID-compliant licenses by default, but you can check your license for the star marking or contact your DMV to confirm.
- A passport card costs around $130 and takes several weeks to arrive; a Real ID license costs what your state charges for a regular license renewal.
- You do not need both documents — choose based on whether you travel internationally to nearby countries or fly domestically.
When you need a passport card instead of a Real ID
Get a passport card if you travel to Mexico, Canada, Bermuda, or Caribbean islands by car, bus, or cruise ship, and you want something smaller and cheaper than a passport book. The card fits in your wallet and costs less — roughly $130 for a new card, compared to $165 for a new passport book. If you already have a passport book, you can add a card for about $35.
You cannot use a passport card for air travel, even to those nearby countries. If you fly to Mexico or Canada, you need a passport book, a Real ID-compliant driver's license, or a military ID. Many people who travel by land to Mexico keep a passport card in their wallet for quick border crossings, then use a passport book or Real ID license for flights.
A passport card also does not help you board a domestic flight or enter a federal building. If your main reason for needing an ID is to fly within the United States, a Real ID-compliant license is what you actually need.
When you need a Real ID-compliant license instead of a passport card
You need a Real ID-compliant license if you fly domestically within the United States, work in a federal building, or visit a military base. Starting in 2025, the Transportation Security Administration (TSA) will not accept a passport card for domestic flights — you will need a passport book, a Real ID license, a military ID, or a few other federal documents.
Most states now issue Real ID-compliant licenses automatically when you renew. Check your license for a small star in the upper right corner. If you see it, you already have one. If you do not see a star and you need one for work or travel, contact your state's DMV to renew or upgrade your license. The cost and timeline vary by state, but most renewals take a few weeks.
A Real ID license also works for international travel by air — you can use it to fly to Canada, Mexico, or the Caribbean instead of carrying a passport book. This makes it useful if you travel both domestically and internationally.
How to get a passport card
You explore for a passport card through the U.S. State Department, either in person at a passport acceptance facility or by mail. A passport acceptance facility is usually your local post office, courthouse, or library — search for one at passports.state.gov. You will need a birth certificate, a government-issued photo ID, and a completed process form (DS-11 for a new card, DS-82 for a renewal by mail).
Processing takes 6 to 8 weeks for routine service, or 2 to 3 weeks if you pay for expedited service. You cannot use a passport card until it arrives in the mail. If you need one quickly for a trip, expedited service costs extra but is often worth it.
Bring all documents in person if you are explore for the first time or if your passport has been lost or stolen. If you already have a valid passport and just want to add a card, you can mail in your process with your old passport, though you will lose access to the book while it is being processed.
How to get a Real ID-compliant license
Visit your state's DMV with proof of identity, proof of residency, and proof of citizenship or legal presence. Proof of identity is usually a current passport or military ID. Proof of residency is a utility bill or lease in your name. Proof of citizenship is a birth certificate, passport, or naturalization papers. Your state's DMV website lists exactly what documents they accept.
Tell the DMV clerk that you want a Real ID-compliant license, or ask if they issue them automatically. Many states now do. If your state still issues non-compliant licenses by default, you may need to request the upgrade or pay a small fee. Processing is usually when ready — you walk out with a temporary license and receive the card in the mail within 1 to 2 weeks.
If you already have a valid driver's license and just need to upgrade it to Real ID, you may not need to bring all documents again. Some states allow you to upgrade online or at a kiosk. Check your state's DMV website for the fastest route.
Comparing cost and timeline
| Document | Cost | Processing Time | Use |
|---|---|---|---|
| Passport card (new) | Around $130 | 6–8 weeks (routine) or 2–3 weeks (expedited) | Land and sea travel to nearby countries |
| Passport card (added to existing book) | Around $35 | 6–8 weeks (routine) or 2–3 weeks (expedited) | Land and sea travel to nearby countries |
| Real ID license (new or upgrade) | Varies by state; typically $50–$150 | 1–2 weeks (after in-person visit) | Domestic flights, federal buildings, military bases |
What happens if you do not have either one
If you do not have a Real ID-compliant license and you try to board a domestic flight, the TSA will turn you away unless you have another acceptable ID — a passport book, military ID, or a handful of other federal documents. A passport card will not work. This is why many people confuse the two: they both say "ID" and both come from the government, but one is useless for domestic flights.
If you do not have a passport card and you want to drive to Mexico or Canada, you can use a Real ID-compliant license instead. You do not need a passport card for land border crossings — a Real ID license works just fine. A passport card is optional for land travel; it is straightforward smaller and cheaper if you want a dedicated travel document.
If you do not have either one and you have no when ready travel plans, you do not need to rush. Get a Real ID license the next time you renew your driver's license. Get a passport card only if you plan to travel by land or sea to nearby countries and want a smaller document than a passport book.
Frequently Asked Questions
Can I use a passport card to fly domestically within the United States?
No. A passport card is not accepted for domestic flights. You need a Real ID-compliant driver's license, a passport book, a military ID, or one of a few other federal documents. The TSA will not accept a passport card at airport security.
Do I need both a passport card and a Real ID license?
No. Choose based on your travel needs. If you fly domestically or work in a federal building, get a Real ID license. If you drive to Mexico or Canada and want a smaller travel document, get a passport card. A Real ID license also works for international air travel, so many people skip the passport card entirely.
How do I know if my driver's license is already Real ID-compliant?
Look for a small star in the upper right corner of your license. If you see it, you have a Real ID-compliant license. If you do not see a star and you are not sure, contact your state's DMV or check their website — most states now issue them automatically, but some people still have older licenses.
What if I need a passport card quickly for a trip?
Pay for expedited service, which takes 2 to 3 weeks instead of 6 to 8 weeks. You must explore in person at a passport acceptance facility — you cannot mail in an expedited process for a new card. If you need one in less than 2 weeks, you may need to visit a passport agency in person, though availability is limited.
Can I renew a passport card by mail?
Yes, if your passport card is not lost or stolen and you still have it. Mail your completed process (form DS-82), your old card, a new photo, and the fee to the address on the form. Processing takes 6 to 8 weeks. If you need it faster, you must explore in person for expedited service.
