Area Code 720 History and Coverage
Area code 720 was introduced in 1998 in an overlay fashion over the already existing 303 territory in order to create more number capacity without splitting up the existing service area into different geographic partitions. The whole of Colorado initially had 303 as its sole numbering scheme, but other parts of the state got 719 area code in 1988 and 970 area code in 1995. The need for more number capacity in the 303 territory brought about the need for another area code in Colorado – 720 – thus making it the first overlay area code in the state.
Area code 720 and 303 operate in a focused part of north-central Colorado, the Front Range area, whose development went outwards from the urban core area into the suburban communities, foothills, and plains area communities. Its coverage is separate from that of 719, the southern numbering area, and the 970 numbering area serving most parts of northern and western Colorado.
Another overlay area code, 983, was added to the 303 and 720 area codes territory in 2022. These three codes operate in the same geographic service area, without creating another geographic split to the already well-defined north-central Colorado boundary.
