Origin Story
Area code 303 was one of the original area codes established in 1947, initially covering the entire state of Colorado. For 41 years, it served as the sole area code for the state. In 1988, a geographic split was necessary due to growth, and the 719 area code was created to serve southern Colorado, while 303 retained the northern and central regions, including Denver. The continued expansion of the Denver metro area led to the introduction of the 720 overlay area code in 1998 to provide additional numbering capacity without requiring existing customers to change their numbers. In 1995, the 970 area code was split off to serve the western and northeastern parts of the state, further refining the geographic boundaries. Today, 303, along with its overlays 720 and 983, serves the core of Colorado's Front Range, a testament to the region's enduring growth and economic vitality.
