The dataset lists 24 associated cities for area code 720, each with its own latitude and longitude. These city associations reflect the communities served by the numbering area when the data was compiled.

Area code 720 falls within Colorado. Area codes are assigned geographically, but because of number portability a phone number does not always stay in the region it was originally issued for.

The approximate centre of this numbering area is located at latitude 39.77756 and longitude -105.00267, placing it within Colorado. Coordinates are averaged from the associated city data and should be treated as a general reference point.

Area code 720 is one of hundreds of codes in the North American Numbering Plan. Codes are opened, split and overlaid by numbering administrators as demand changes, so city and region associations can shift over time.

Because of number portability, the current location of a phone number may differ from the area shown here. This page describes the area code assignment, not the physical location of an individual subscriber in United States.

Data Source

Area-code data is imported from Area Code Geolocation Database, a North American area-code geolocation database. GitHub.

This is a snapshot of an external open dataset, not a live telecom feed. Area-code boundaries and city associations may change over time, and number portability means an individual number may not be located where its area code suggests. Always confirm details with the relevant carrier or authority before relying on them.

Portability note: numbers can be moved between providers and regions, so an area code does not guarantee the caller's actual location.
