Starting May 7, 2025, all U.S. travelers aged 18+ must present a REAL ID-compliant license or an accepted form of ID—such as a passport or military ID—to board domestic flights or enter federal facilities. REAL IDs have a star marking and require in-person DMV verification with identity and residency documents. Without one, travelers face extra screening. Apply early at your DMV to avoid delays and ensure smooth travel and access to secure locations.
