The 970 area code is a North American Numbering Plan area code which serves the state of Colorado. This particular area code was put into service in May 1995. It was created from a split of the 303 area code. It is located in the Mountain Time Zone, for which it shares with 303, 720, and 970. It covers the vast majority of the western part of the state, including the cities of Grand Junction, Commerce City, Alamosa, Durango, and Fort Collins.

The North American Numbering Plan (NANP) is an integrated system used by Canada, the United States, and many Caribbean countries to manage telephone numbering plans. Created in 1947, the NANP divides the geographic regions into Numbering Plan Areas (NPAs). Each NPA is assigned a three-digit prefix known as an area code. Generally, larger metropolitan areas are given two or more prefixes, while smaller cities and towns are assigned just one prefix. Calls made between Numbers within the same NPA code are considered local calls and no long-distance fees are applied.
