History of 983 Area Code

To keep up with continued growth in the Denver metropolitan area, the 983 area code was introduced as another overlay. It officially began service on June 17, 2022, becoming Colorado’s fifth area code. The 983 code was also one of 19 new area codes added across the United States that year.
Currently, Colorado has six area codes. In addition to 303, 720, and 983, the state also uses 719, 970, and the newest 748 area code, which was added in 2025 as an overlay to the 970 region to meet ongoing demand for new numbers.
