A Real ID works for domestic travel, but not for international travel or federal buildings

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 lets you board domestic flights within the United States and enter federal buildings without a passport. However, it does not work for international travel, cruises that leave U.S. ports, or entry into countries outside the U.S. — for those, you need a passport.

The key difference: Real ID proves your identity to U.S. authorities for domestic purposes. A passport proves your citizenship to foreign governments and U.S. Customs. They serve different functions, and one does not replace the other.

Key Takeaways

  • A Real ID works for domestic flights, federal buildings, and military bases, but you cannot use it to leave the country or enter another country.
  • You can get a Real ID from your state's DMV by bringing a birth certificate, proof of residence, and your current driver's license or ID card.
  • Real ID and passport serve different purposes — Real ID is for domestic federal access, passport is for international travel and citizenship proof.
  • If you travel internationally even once a year, getting a passport is usually more practical than relying on Real ID for everything else.

What a Real ID actually covers

A Real ID is accepted for boarding commercial flights within the United States, entering federal buildings (including courthouses and some government offices), and accessing military bases. You can use it anywhere inside U.S. borders where a federal ID is required. Starting May 7, 2025, a Real ID or passport became required for all domestic air travel — you can no longer use a regular driver's license alone.

Real ID does not work for travel outside the U.S., including cruises that depart from U.S. ports and return to U.S. ports. It also does not work for entering Canada, Mexico, or any other country, even by land. If you cross a border, U.S. Customs will ask for a passport or passport card.

What you need to get a Real ID from your state

The process varies slightly by state, but all states require the same core documents. You will need to visit your state's DMV in person — you cannot get a Real ID by mail or online. Bring your current driver's license or state ID card, a birth certificate (original or certified copy), and proof of your current address (a utility bill, lease, or bank statement dated within the last 60 days works for most states).

Some states also ask for a Social Security number verification document, such as a W-2 or Social Security card. A few states charge a fee for Real ID (typically $10 to $30), while others include it at no extra cost when you renew. Check your state's DMV website for the exact list before you go, because showing up without the right documents means a wasted trip.

Processing time is usually when ready or within a few days if done in person. Your new Real ID card will arrive by mail within two to three weeks.

When you actually need a passport instead

Get a passport if you travel outside the U.S. at all, even occasionally. A passport is required for any international air travel, land border crossing, or sea travel outside U.S. waters. It is also the only document that proves U.S. citizenship to a foreign government — Real ID does not.

A passport takes four to six weeks to arrive through the standard process, or one to two weeks if you pay for expedited service. If you already have a passport, you do not need a Real ID for domestic flights — your passport works for that too. But if you only fly domestically and never leave the country, Real ID is simpler and faster to obtain.

Real ID vs. passport: which one to get first

If you travel internationally at all, get a passport first. It covers everything Real ID does for travel purposes, plus international trips. If you only fly domestically and have no plans to leave the U.S., Real ID is faster and cheaper.

You can have both. Many people carry a Real ID for everyday domestic use and a passport for international travel. Real ID is also useful if you need to enter federal buildings frequently — you do not have to carry your passport for that.

Real ID and passport card: not the same thing

A passport card is a wallet-sized version of a passport. It works for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean, but not for air travel outside the U.S. It is cheaper and faster to get than a full passport book, but it is more limited. Do not confuse it with Real ID — they are completely different documents issued by different agencies.

A passport card does not work for domestic flights. Real ID does. If you want to fly domestically, you need either Real ID or a full passport book.

Frequently Asked Questions

Can I use my Real ID to fly to Canada or Mexico?

No. Real ID only works for domestic flights within the U.S. For any international flight, including to Canada or Mexico, you need a passport book or passport card. For land or sea travel to Canada, Mexico, Bermuda, or the Caribbean, a passport card works, but Real ID does not.

Do I need both a Real ID and a passport?

Not necessarily. If you have a passport, it covers domestic flights and federal building access. If you only travel domestically, Real ID alone is sufficient. Many people carry both for convenience — Real ID for everyday use and passport for international trips.

How long does it take to get a Real ID?

If you explore in person at your state's DMV, you usually get your Real ID card within two to three weeks by mail. Some states issue it on the spot. Check your state's DMV website for timing. A passport takes four to six weeks standard, or one to two weeks expedited.

What if my state hasn't issued me a Real ID yet?

All U.S. states now issue Real ID. Visit your state's DMV website to find the nearest office and confirm what documents to bring. If you cannot get a Real ID before your flight, you can use a passport, passport card, military ID, or other federal ID listed on the TSA website.

Is Real ID the same as a REAL ID compliant license?

Yes. A "Real ID compliant" driver's license is a Real ID. The term just means your state's license meets the federal security standards. Your license will have a star symbol in the upper right corner if it is Real ID compliant.
