REAL ID for domestic flights requires adults traveling within the United States in 2026 to carry a REAL ID-compliant state license or another TSA-accepted document, such as a valid U.S. passport or passport card. Without acceptable identification, travelers may face delays, extra verification, or denial of checkpoint access.

This REAL ID for domestic flights guide separates domestic identification rules from international passport requirements. Airport identification can be confusing because passport books, passport cards, and state IDs serve different purposes. This guide explains what adult travelers should carry, what happens when an ID is not compliant, and how to prepare before leaving for the airport.

REAL ID for domestic flights: what adults need in 2026

REAL ID for domestic flights

For REAL ID for domestic flights compliance, travelers age 18 and older must show acceptable identification at the TSA checkpoint. Since May 7, 2025, TSA has not accepted non-REAL ID-compliant state driver’s licenses or state identification cards as standard checkpoint identification. Travelers should use a REAL ID-compliant credential or another document on TSA’s current acceptable-ID list.

According to the Transportation Security Administration, accepted alternatives include a U.S. passport, U.S. passport card, permanent resident card, DHS trusted traveler card, Department of Defense ID, and several other government credentials. Because TSA says the list can change, check the official page again shortly before travel. Treat REAL ID for domestic flights as a pre-departure checklist item, not an airport-day decision.

How to check a REAL ID for domestic flights

A REAL ID-compliant license or state ID normally displays a star marking near the top of the card. Designs vary by state, so travelers who are uncertain should verify the credential with their state motor vehicle agency rather than relying only on appearance.

  • Check the front of the card for the state’s REAL ID marking.
  • Confirm that the credential will remain valid through the travel date.
  • Match the name on the ID with the airline reservation.
  • Carry an accepted alternative if there is any uncertainty.

REAL ID, passport book, or passport card: which should you carry?

Document U.S. domestic flights International flights Best use
REAL ID-compliant state license or ID Accepted Not a substitute for a passport Routine domestic travel
U.S. passport book Accepted Accepted for international air travel, subject to destination rules Domestic and international travelers
U.S. passport card Accepted Not valid for international air travel Wallet-sized domestic-flight alternative
Non-compliant state license or ID Not accepted as standard TSA identification Not a passport Replace it or carry another accepted ID

When comparing REAL ID for domestic flights with passport options, the U.S. Department of State confirms that both the passport book and passport card are accepted domestic alternatives. However, the passport card is not valid for international air travel. Travelers planning trips outside the United States generally need a passport book and must also meet the destination’s entry and validity rules.

What happens if you arrive without a REAL ID?

A traveler presenting a non-compliant state ID without another accepted document may be directed to a separate area for additional identity verification and screening. TSA states that checkpoint access can be denied if the traveler refuses to provide acceptable identification, declines the verification process, or cannot have their identity confirmed.

REAL ID for domestic flights helps travelers avoid preventable identity-verification delays. Do not treat additional screening as a guaranteed backup plan. Bring an accepted physical document and allow extra time whenever identification may be questioned.

Do children need identification for domestic flights?

TSA generally does not require children under 18 to provide identification when traveling within the United States, but airlines may have their own age-verification or unaccompanied-minor requirements. The accompanying adult should carry acceptable identification and confirm the airline’s policy before departure.

Does TSA PreCheck replace the REAL ID requirement?

No. TSA PreCheck changes the screening process but does not replace the identification requirement. Adult travelers using PreCheck should still carry a REAL ID-compliant credential or another accepted form of identification.

What should international travelers check?

International air travel typically requires a passport book. Entry rules can also depend on nationality, destination, transit airports, visa status, and passport validity. Some destinations require a passport to remain valid for months beyond the planned departure date.

Before booking, review official destination requirements and consider Desmo Travel’s passport and visa services. Travelers comparing routes can also contact the Desmo Travel airfare team or submit a flight quote request.

Frequently asked questions

Can I fly domestically with a passport instead of a REAL ID?

Yes. A valid U.S. passport book is an accepted alternative for domestic flights.

Can I use a passport card at a TSA checkpoint?

Yes. A valid U.S. passport card can be used for domestic air travel, but it cannot be used for international air travel.

Is a temporary driver’s license accepted by TSA?

TSA’s acceptable-identification guidance says a temporary driver’s license is not an accepted checkpoint ID. Carry another accepted document.

Can I use an expired ID?

TSA guidance can change and may distinguish between document types and expiration periods. Check the current official acceptable-ID page before travel and use a valid document whenever possible.

What if my ticket name does not match my ID?

Contact the airline before travel. Even small name differences can create delays, especially on international itineraries.
