Phone numbers with the 748 area code originate from the western and northern regions of Colorado.
Area code 748 is an overlay of area code 970 . Area code 970 was established on April 2, 1995. Area code 748 was activated on July 7, 2025. Ten-digit dialing is required in this region.
No, 748 is a newly assigned Colorado area code serving the northern and western parts of the state as an overlay to 970. Scammers love spoofing newly minted overlays to trick locals who recognize it as a state number but haven't learned to block it yet.
Sharing the identical geographic footprint of the 970 prefix, this code inherits the region's rampant property and utility fraud. Expect a heavy volume of unsolicited cash offers for mountain properties from fake real estate wholesalers, as well as aggressive Xcel Energy imposters threatening to shut off power to rural homes.
