REAL ID vs. passport: Which one do you need to travel?

If you have flown or have been planning to fly through U.S. airports, you may have heard about new federal ID requirements. Those rules now apply at airport security and travelers need ID that meets certain requirements. A driver’s license may not be enough if it doesn’t satisfy the new REAL ID requirements. To help you understand which ID you need when and if your license is compliant, read our helpful guide.

If you've ever stood in an airport security line wondering whether your driver’s license is a valid form of identification, you're not alone. The rules around REAL ID vs. passport can be confusing, especially with new federal travel requirements in place. While both are official identification documents, they serve very different functions. Here's how to recognize their distinct purposes and when to use each one.

The purpose of REAL ID

The REAL ID Act, passed in 2005, was designed to strengthen security standards for state-issued driver’s licenses and identification cards. A REAL ID-compliant card verifies your identity by showing proof of citizenship or legal presence, a Social Security number, and proof of address. 

If you’re 18 or older and flying domestically in the U.S., remember you will need a REAL ID or another valid ID such as your passport. This rule came into force in May 2025.

How to identify a REAL ID-compliant card

To check whether your license meets the standard, look for a small star in the upper-right corner. That star—gold or black, depending on your state—means your ID complies with federal regulations. If you don't see one, you'll need to bring another form of identification, like a passport, to clear airport security.

Domestic U.S. air travel

To board a U.S. flight, you’ll need a REAL ID or another TSA-approved form of identification, such as a valid passport or a passport card.  Many travelers still opt to get a REAL ID even if they already have a passport, since it's convenient for everyday travel and allows you to keep your passport safely at home for domestic trips.

International air travel

Because it's internationally standardized, the passport book is accepted everywhere as proof of citizenship and identity. To fly internationally, you must have a valid passport book, even for short trips to Canada, Mexico, or the Caribbean. It's the single most important document for global travel and the one item you should double-check before you book an international flight.

The U.S. passport book, the globally recognized blue document issued by the U.S. Department of State, contains your name, photograph, date and place of birth, and passport number, along with pages for visas and entry stamps. When border officials scan it, they can instantly verify your identity and nationality, no matter what language they speak or where you're traveling.

Land and sea travel: A note on passport cards

The passport card is only valid for travel by land or sea between the U.S. and certain neighboring countries, such as Canada, Mexico, Bermuda, and most Caribbean destinations. It's useful if you frequently cross these borders but never plan to fly internationally. The benefit of the passport card is that it’s smaller, wallet-sized, affordable, and convenient for frequent cross-border travelers. If you plan to fly internationally, you’ll need a full passport book.

Cost

When it comes to cost, a REAL ID is typically the more affordable option than a passport book with fees varying by state. A U.S. passport book costs USD 130 for adults with additional fees depending on how you apply.  A passport card can be added for USD 30 more. If your travel is strictly within U.S. borders, a REAL ID is sufficient. But if you plan to go abroad, the passport book is a smart long-term investment.

Validity

As for validity, a REAL ID generally lasts four to eight years, depending on state regulations, while a passport book is valid for ten years and five for children under 16. The passport wins for both longevity and versatility.

Application process

The application process also differs. You can apply for a REAL ID at your local driver licensing agency, where you'll need to bring original documents such as your birth certificate or passport, your Social Security card, and two proofs of address. A passport application goes through the U.S. State Department and can be submitted by post or in person at a post office, library, or courthouse. 

REAL IDs usually arrive within a few weeks, while standard passport processing can take six to eight weeks – though expedited options are available if you're in a hurry. If you need to apply for a passport or renew one, you can do so through the U.S. Department of State, which also provides details on applying for a child's passport and other related requirements.

If you mostly fly within the U.S., a REAL ID will meet your needs and save you some money. If you travel internationally, or think you might someday, a passport book is worth having on hand. Many travelers carry both: a REAL ID for convenience and domestic travel and a passport book for international travel.  When in doubt, choose the passport book. With it, you can travel with confidence wherever your journey takes you.
