Oklahoma State in United States

Oklahoma, the Sooner State, blends Native American heritage, Western culture, and a strong energy economy. With its expansive plains, storm-chasing skies, and historical Route 66, Oklahoma offers a unique slice of Americana. Cities like Tulsa and Oklahoma City are growing hubs for aerospace and tech innovation.

Originally covered by area code 405, Oklahoma’s growing population led to the creation of 918 for the northeastern region and 580 for the rural west and south. In 2021, 572 was added as an overlay to 405 due to increasing demand. These Oklahoma area codes support both expanding urban economies and wide-reaching rural connections.
