Area code 928 serves northern and western Arizona, including Flagstaff, Yuma, Prescott, and parts of the Navajo Nation. It was created in 2001 from a split with 520 to support a geographically diverse area spanning deserts, forests, and high-elevation towns. Seven-digit dialing is still used in many areas. Area code 928 encompasses rural communities, tribal lands, and tourist hubs like the Grand Canyon, making it a distinct identifier for Arizona’s scenic and cultural variety beyond the Phoenix and Tucson metro areas.
