Colorado to Introduce New Area Code in 2026

Colorado's Public Utility Commission has announced that a new area code, 748, will be introduced in the first quarter of 2026 for customers in the 970-area code overlay region who request new services or move their existing service. Current customers will retain their existing phone numbers and area codes. The new area code is necessary as the current 970 area code is projected to run out of phone numbers by 2026. This will be Colorado's sixth area code, with the implementation process expected to take nine months.
