720 Area Code - Denver, Colorado


The 720 area code was first put into use on June 1, 1998, and it serves Denver, CO and some of the surrounding cities. This area code does overlap with the 303 area code in certain regions. A total of 36% of 720 area code residents use a landline phone, while the others use wireless phones. Some of the major telecommunications carriers of this area code include Sprint, Cingular, Qwest Corporation, T-Mobile, and Verizon Wireless.

This area code was initially created as an overlay to the original 303 area code, which has been split a total of two times, once in 1988 and again in 1995. These splits failed to achieve the relief that officials were hoping for, which is why another split was done in 1998. As a result of these splits, it is now necessary for all central Colorado residents to dial ten digits when placing local calls.

The city of Boulder, Colorado is part of the 720 area code, and it is known for its large population of liberal democrats as well as the beautiful scenery offered by the Rocky Mountains. This mountain range spans over 3,000 miles, going from the U.S. into parts of Canada.

There is no question that the Rocky Mountains is one of the main reasons why so many tourists flock to the Boulder area each year for skiing, hiking, and some of the best views the United States has to offer. There is also the University of Colorado in Boulder, which has an incredibly beautiful mountainous backdrop. There are 30,000 undergraduate students here, so the school makes up a large portion of this city’s total population.

The city of Lakewood can also be found in the 720 area code, and it is one of the more populated cities in all of Colorado. It has a population of around 150,000 people and a semi-arid climate. The winter months in this area tend to be very snowy and cold, while the summers go into the extreme high temperatures. Skiing is a major tourist draw because of all the snow-capped mountains in the winter months. All of the tourist activity makes up a major chunk of this area’s economy.

The government also plays an important role in Lakewood’s economy, and the Federal Center is located in Denver. This government building employs over 6,000 people, and it is also the location of the National Ice Laboratory. This laboratory is important for a number of reasons, and it hosts ice cores from all over the planet. The geological research that is conducted here has some very serious implications for the future, which is why it receives so much funding from the federal government.

The medical services as well as school system are the two biggest sources of employment in the 720 area code. A number of shopping malls have been built here as well, adding yet another draw for tourists who come for the skiing and beautiful mountain views. These malls have employed hundreds upon hundreds of people, thereby helping out the local economy quite a bit. The Colorado Mills Mall opened back in 2002, and it has stores like Saks Fifth Avenue as well as Neiman Marcus.

There are a lot of great restaurants in the 720 area code, offering something for everyone. There is also a movie theater and a skate park in Colorado Mills. This city has the strongest economy in the entire area because of all the businesses that exist. There are still new businesses popping up all the time, indicating just how strong the economy really is.

Westminster is another city in the 720 area code, and it is a suburb of Denver. This city can be found just a few minutes from the state capital, and it is another major population center in Colorado. This region of the 720 area code has been named one of the best places to live by Money Magazine on a number of occasions due to the strong economy, tourism industry, and low crime rate.

You will find that there are quite a few noteworthy landmarks in Westminster, including Westminster Castle. This historic landmark is visited by hundreds of thousands of tourists each year, and it actually appears on the National Register of Historic Places for this region. There is also Westminster University, which is considered one of the best places for undergraduate programs of all kinds in the country. One of the truly unique things about this school is that it has a particularly low tuition, and has since it was built back in the early 1900s.
