Phone numbers with the 303 area code prefix originate from the north-central portion of Colorado. This region specifically comprises the metropolitan areas of Denver and Boulder, along with their surrounding suburbs. It represents the primary numbering plan area for the state's Front Range, a densely populated region.
The 303 area code operates as part of an overlay complex with area codes 720 and 983 , serving the same geographic region. Area code 303 was the original area code for the entire state of Colorado, introduced in 1947, and later reduced in geographic extent. Area code 720 was added as an overlay on September 1, 1998, followed by area code 983, which was activated on June 17, 2022. Due to this overlay system, ten-digit dialing is required for all calls made within this service area.
Denver, Boulder, and Aurora fall within the 303 area code, the established code for Colorado's most populous corridor. Federal benefits administrators from the Denver Federal Center, DaVita dialysis schedulers, and University of Colorado Boulder alumni callers are among the most frequent contacts.
