Ten-digit dialing
Area code 970 has PCS telephone numbers assigned for the central office code 988 in the Fort Collins exchange. 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 has ordered telecommunication carriers of 83 area codes, including 970, to transition to
ten-digit dialing, even when the area code is not part of an
overlay plan. Alternatively, the 988 prefix may be retired in the local numbering plan. Per the timeline set by the North American Numbering Plan Administrator, permissive dialing begins on April 24, 2021 and ten-digit dialing is required starting on October 24, 2021.
