720 Area Code: Location, Time Zone & Phone Lookup - Page 2

The history of area code 720 is an interesting one. This area code was originally created for the state of Colorado in 1995. However, it was not actually put into use until 1996. At that time, it was responsible for the entire Denver metropolitan area. However, as the area continued to grow, it soon became apparent that a new area code was needed. In 2002, area code 303 was created to serve the eastern portion of the Denver metro area. This left area code 720 responsible for the western portion. However, as the years have passed, the boundaries between the two area codes have become more and more blurred. In fact, there are now several areas in the Denver metro area that are served by both area codes.

Despite the fact that area code 720 is no longer responsible for the entire Denver metro area, it is still a very important area code. In fact, it is the third-largest area code in the state of Colorado. And, even though it is no longer the primary area code for the Denver metro area, it is still responsible for a large population.

So, what is the history of area code 720? As you can see, it is a history that is still very much in flux. However, it is a history that is sure to continue to evolve in the years to come.

Area code 720 serves the Denver metropolitan area in the US state of Colorado. The code was created on July 1, 1998, and was the first new area code in Colorado since area code 303 was created in 1947. Area code 720 is an overlay code for area codes 303 and 720.
