About the 720 area code
Denver, Colorado, sits at the center of area code 720, whose numbers also appear in Aurora, Thornton, Westminster, and Brighton. Mountain time is kept throughout the territory.
The code joined the 303 area as an overlay in 1998 and now shares that footprint with both 303 and 983. Three codes serving one map keep local dialing at ten digits across the region.
Dialing note: 720 is part of an overlay complex with 303, 983, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
