REAL ID vs. Passport: Which Do You Need to Fly?

Short answer

For domestic U.S. flights you need either a REAL ID-compliant driver's license (marked with a star) or another TSA-accepted ID such as a passport book or passport card. For international flights you always need a passport book — a REAL ID cannot cross any border. A valid passport works for both, so frequent flyers often skip REAL ID entirely.

What REAL ID changed

Since enforcement began on May 7, 2025, every adult boarding a domestic flight or entering certain federal facilities must show a REAL ID-compliant license or another accepted document. Compliant licenses are marked with a star in the upper corner; if your license says 'Not for federal purposes,' it won't work at TSA.

REAL ID is a state-issued driver's license or ID standard — it is not a passport replacement and has no use outside the United States.

Documents TSA accepts besides a REAL ID

A valid U.S. passport book or passport card clears TSA for any domestic flight. TSA also accepts trusted-traveler cards (Global Entry, NEXUS, SENTRI), military IDs, permanent resident cards, and several others — the full list lives on TSA's identification page.

If you already hold a valid passport, you don't strictly need a REAL ID for air travel. Many travelers keep using their passport domestically and never upgrade their license.

When you need a passport book

Any international air travel requires a passport book — no exceptions for REAL ID or passport cards. Passport cards work only at land borders and sea ports of entry for Canada, Mexico, Bermuda, and the Caribbean.

Also remember validity rules: many destinations require 3–6 months of remaining validity. Check our expired-passport guide before you book.

Getting a REAL ID

REAL ID is issued by your state DMV, not any passport office. You'll bring proof of identity (a birth certificate or passport), your Social Security number, and two proofs of state residency. Requirements and appointment availability vary by state.
