You might’ve heard about REAL ID, which is a program that requires Americans to use specific types of identification enter airports, certain federal facilities and nuclear power plants. Since you’re probably curious about its travel implications, that’s what we’ll focus on here.
Beginning on May 7, 2025, all travelers flying on commercial aircraft will be required to present a REAL ID–compliant identity document. But does REAL ID replace a passport for international travel? No, it does not. Here’s everything you need to know about REAL IDs vs. passports.
What is a REAL ID?
The REAL ID Act was passed by Congress in 2005 to “set standards for the issuance of sources of identification, such as driver’s licenses.” Because many forms of ID are issued by states rather than the federal government, they’re not all on the same page regarding security. The REAL ID Act aims to bring IDs used for high-security situations up to the same level on a national scale.
Why do you need a REAL ID?
Starting May 7, 2025, all travelers flying on commercial aircraft will need a REAL ID–compliant identity document to go through airport security. Each state will issue its own REAL IDs, which will often be a special kind of driver’s license. But there are also non–driver’s license forms of REAL ID, too.
Is the application for a REAL ID easier than for a passport?
There is no standard application for REAL IDs. It varies per state. Generally speaking, it’s fairly easy to get a REAL ID, and it usually will take less time to process than a passport. Most states’ processes include bringing various documents to the Department of Motor Vehicles (DMV) that prove your identity and residency in the state, then you will receive your ID in the mail.
But if you are looking to get a REAL ID driver’s license, and you do not already have a driver’s license, that will take far more effort, as you will have to take a permit test and practice driving with a learner permit first. Passport applications require filing out paperwork, showing documents and going to a passport acceptance facility in-person.
REAL ID versus passport: Which one do you need for domestic travel?
Starting May 7, 2025, you will need a REAL ID–compliant form of identification to go through airport security for domestic flights. Passports are accepted as an alternative to REAL IDs, so you can use one at airport security.

Does the REAL ID replace the passport for international travel?
No, you will not be able to use a REAL ID to travel internationally. You must have a passport or a passport card (depending on your destination) to travel internationally.
The passport is the ultimate form of ID for travel. It’s required for international flights, but it’s also accepted as a REAL ID alternative for domestic flights. That said, it’s not a bad idea to get a REAL ID, so you don’t need to use your passport for domestic travel. Instead, you can keep it safe at home.
Conclusion
REAL IDs will not be accepted for international travel, but they will be required for domestic air travel beginning May 7, 2025. A passport will be accepted as an alternative to a REAL ID, and it can be used for international travel.
