A 720 phone number links to the Denver metropolitan numbering region in Colorado. This guide explains history, dialing rules, business uses, and common questions people ask.
What is the 720 Area Code?
Area code 720 serves north-central Colorado inside the Denver metropolitan region. It covers a territory shared by 303 and 983 across several busy cities.
NANPA gave 720 as an overlay for 303 in March 1998. The line started working on September 1, 1998. This move added many more phone numbers. The 303/720 zone now includes area code 983. It arrived on June 17, 2022. Officials chose this second overlay because the pool of digits ran low.
This region wraps around Denver and towns in north-central Colorado. It touches Adams, Arapahoe, Boulder, Broomfield, Douglas, Jefferson, and Elbert counties in the western United States.

How Do 720 Area Code Phone Numbers Work?
A business number with a 720 area code works like other North American phone lines. The first three digits mark the region while the rest point to an individual user.
Codes 303, 720, and 983 serve the same geographic area. Choosing a 720 prefix does not mean your company operates in a separate physical coverage area. People in this region must dial 10 digits for local calls. Reaching 720-848-4321 means you enter the full area code plus the seven-digit telephone number.
- +1 represents the United States of America.
- 720 is the area code for Denver, Colorado.
- 848 is the three-digits shows the central office.
- Next, the four digits, 4321, belongs to the specific subscriber.
A virtual 720 line sends calls through a VoIP provider. This setup stops a business from needing a traditional phone line at one fixed office.
