'''Area code 970''' is a telephone [[area code]] in the [[North American Numbering Plan]] (NANP) for the western and northern parts of the [[U.S.]] of [[State of Colorado]]. The [[numbering plan area]] includes [[Aspen, Colorado|Aspen]], [[Breckenridge, Colorado|Breckenridge]], [[Durango, Colorado|Durango]], [[Estes Park]], [[Fort Collins]], [[Glenwood Springs]], [[Grand Junction, Colorado|Grand Junction]], [[Greeley, Colorado|Greeley]], [[Loveland, Colorado|Loveland]], [[Silverthorne]], [[Steamboat Springs, Colorado|Steamboat Springs]], and [[Vail]].<br />
<br />
==History==<br />
Area code 970 was established on April 2, 1995 in an [[area code split]] of [[area code 303]], which was retained by the [[Denver metropolitan area]].<ref>{{cite web<br />

In 2023, the North American Numbering Plan Administrator estimated that area code 970 would reach numbering exhaustion by 2026. On December 18, 2023, the [[Colorado Public Utilities Commission]] approved the addition of '''area code 748''' for the all-services distributed overlay of NPA 970.<ref name=area_code_748>{{cite news|url=https://www.cpr.org/2023/12/18/new-area-code-for-northern-and-western-colorado-2026/|title=A new area code is coming to northern and western Colorado in 2026|publisher=[[Colorado Public Radio]]|first=Paolo|last=Zialcita|date=2023-12-18|access-date=2025-05-06}}</ref> The overlay complex is scheduled for service on July 7, 2025.<ref>{{cite web<br />

<br />
===Ten-digit dialing===<br />
Area code 970 has PCS telephone numbers assigned for the central office code 988 in the Fort Collins exchange.<ref>[https://www.telcodata.us/search-area-code-exchange-detail?npa=970&exchange=988 Assignment of 988 prefix in Fort Collins], Retrieved 2021-04-05</ref> As of October 17, 2020, ''988'' has been assigned by law as a three-digit code for the [[National Suicide Prevention Lifeline]]. To avoid conflicts in switching systems, the [[Federal Communications Commission]] ordered telecommunication carriers of 83 area codes, including 970, to transition to [[ten-digit dialing]], even when the area code is not involved in an [[overlay complex]]. Per the timeline set by the North American Numbering Plan Administrator, permissive dialing began on April 24, 2021 and ten-digit dialing has been required from October 24, 2021.<ref>{{cite web<br />
