No, a REAL ID is not sufficient for travel to the Bahamas from the United States; you must have a valid U.S. Passport. While the REAL ID Act (enforced starting May 7, 2025) is required for domestic air travel within the U.S., the Bahamas is a sovereign international nation. Even if you are on a "closed-loop" cruise (starting and ending at the same U.S. port), where you can technically use a birth certificate and a government-issued photo ID (like a REAL ID), the "gold standard" advice is to carry a passport in case of an emergency that requires you to fly home. If you are flying to the Bahamas, the airline will not let you board without a passport book. A Passport Card is also acceptable for land and sea entry to the Bahamas but cannot be used for international air travel. For travelers in 2026, the distinction is clear: REAL ID is for TSA domestic checkpoints; a Passport is for international border crossings.
