About Denver

You’re never at a loss for things to do in Denver, Boulder, and the surrounding cities that make up north-central Colorado. In fact, the 720 area code is bursting with fun activities, sprawling sandstone cliffs, and cultural sights to see. From Denver, the 720 area code extends outwards, reaching such iconic spots as the Red Rocks Park & Amphitheater, Dinosaur Ridge, and the Buffalo Bill Museum. Want to hop on over to Boulder? The 720 area code covers that area, too, From Boulder, branch out to explore the great outdoors, visiting Bear Peak, El Dorado Canyon State Park, and the iconic Flatirons. Be sure not to miss some of the 720 area code’s hottest spots, the ultra-modern and architecturally impressive Denver Art Museum and the Denver Botanic Gardens.

Areas Served

As an enclave area code, the 720 area code serves cities located in the northern part of central Colorado. This means that it covers the well-known cities of Denver, Aurora, Westminster, Lakewood, and Boulder. Because the 720 area code is an overlay for the 303 area code, the former is more present in the counties of Arapahoe, Adams, Jefferson, and Boulder as opposed to Denver County.

The History of 720

The History of 720

The 720 area code is actually one of the newer area codes in the country, only beginning to serve the Denver and Boulder areas from 1998 onwards. The “original” Colorado area code was actually 303. And, it remained so for about 40 years until rapid growth led to the need for splits and overlays beginning in the 1980s. After being split twice and being reduced to serve just northern-central Colorado, the 303 area code was finally overlaid in 1998, marking the beginning of 720 numbers in the area. Because of how new the 720 area code is, it’s markedly known as a number for newer implants to the area and for newer businesses just getting started. Also, this means that most of the 303 area codes are found in Denver while the 720 area code is more prominent in the cities of Aurora, Lakewood, Thornton, Arvada, and Commerce City. Currently, the 720 area code only serves 2% of Denver but is expected to continue to expand into the city as companies assign more 720 numbers.
