What is NAICS 48521

NAICS code 48521 covers Interurban and Rural Bus Transportation services, which primarily include scheduled and chartered passenger bus transportation between urban centers and rural areas. Businesses operating under this code provide essential transit solutions connecting smaller communities with metropolitan hubs, often traversing longer distances than urban transit systems. These services play a critical role in ensuring mobility for populations in less densely populated regions where alternative public transportation options are limited or nonexistent. Government agencies contract these services to support public transit objectives, improve regional accessibility, and fulfill mandates related to rural transportation infrastructure and mobility assistance programs. By partnering with private operators, government entities can extend transit reach, reduce social isolation, and promote economic development in underserved areas. These contracts often align with broader initiatives to enhance transportation equity and meet the needs of elderly, disabled, and low-income passengers.
