Area code 970
Area code 970 is an area code in the North American Numbering Plan (NANP) serving most of the western and northern parts of Colorado. The numbering plan area includes Aspen, Breckenridge, Durango, Estes Park, Fort Collins, Glenwood Springs, Grand Junction, Greeley, Loveland, Silverthorne, Steamboat Springs, and Vail. It was established in an area code split from area code 303 on April 2, 1995, in which only the Denver metropolitan area retained area code 303.[2] The split did not effect local calls; they remained local with seven-digit dialing, even when the destination had received the new area code.
