The 720 area code is a prominent telephone area code for the Denver metropolitan area and the Front Range region of Colorado. This area is known for its stunning mountain landscapes, a vibrant outdoor lifestyle, and a rapidly growing economy.
It operates in the Mountain Time Zone and is essential for businesses aiming to establish a local presence and build credibility in one of the United States' most economically powerful and culturally influential regions.
What is 720 Area Code?
The 720 area code was introduced on September 1, 1998, as an overlay to the original 303 area code. The 303 area code had served the entire state of Colorado since 1947, but rapid population growth and the proliferation of mobile phones in the Denver-Boulder area necessitated a new solution.
As an overlay, both the 720 and 303 area codes serve the exact same geographic region. This requires all local calls to be dialed with a full ten-digit number, a standard practice in major metropolitan areas.
