Colorado is home to many area codes that provide telephone service throughout the state. Colorado’s area codes are split between two geographic regions, with the western half of the state covered by 303 and 720, while 719 covers the eastern portion. Each of these three area codes has been in use since 1947, making them some of the oldest active numbers in North America.
303 area code
The 303 area code is used primarily for Denver and its surrounding suburbs. It was one of the first 86 original numbering plan areas (NPAs) created in 1947 when AT&T introduced direct distance dialing to every major city in America. This code originally served all of Colorado until 1995 when it became necessary to add a second code due to population growth and increased demand for phone lines.
The 303 area code serves Denver, Boulder, Aurora, Golden, Lakewood, Littleton, Englewood and other cities and towns throughout the state. The 303 area code has been split twice since its inception in order to accommodate population growth. In 1988 it was split with parts going to 719 and 970; then again in 1995 when 720 was added to serve areas around Denver.
Currently there are no plans for any further splits or overlays within this region as number conservation measures have allowed numbers to be reused more efficiently than they were previously able to be done so. Businesses located within the 303 area code can use local vanity numbers which help them stand out from their competitors by having a unique phone number that spells out their business name or service offering – making it easier for customers to remember how to reach them directly without having memorize long digits!
The 303 area code is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south and Utah to the west. The 303 area code serves over 2 million people who live in more than 200 cities and towns throughout Colorado’s Front Range region. The 303 Area Code has become increasingly popular due its location within close proximity of major metropolitan areas like Denver and Boulder as well as being home to some of Colorado’s most renowned universities such as University Of Colorado at Boulder or Regis University located in Denver. Many businesses have utilized this number for their customer service phone numbers since it is easily recognizable from other states or regions outside of Colorado giving customers a sense of trust when calling them up for assistance.
720 area code
The 720 number was then assigned as an overlay for areas within 303 which allowed customers from both region codes access to local calling services without having to dial long-distance numbers or incur additional fees from their carrier providers. It was created in 1998 as part of a three-way split with 303 and 970.
This area code covers most of the Denver metropolitan area, including Aurora, Boulder, Lakewood, Littleton, and Thornton. Additionally, some outlying communities such as Castle Rock are included within its boundaries. 720 is an overlay for both 303 and 970 areas codes. That means that when making a call from one to the other you must dial 10 digits instead of just seven like before this change occurred in 1998.
As a result of population growth in Colorado’s Front Range region over recent decades there has been an increasing demand for phone numbers resulting in the need for additional area codes being added to meet that demand which includes 303/720/970 triplexing arrangement currently found throughout much of this region today. Consumers living or working within 720 should be aware that many companies require them to use only ten digit dialing even if they are calling another number within their own geographic region so make sure you include all ten digits when placing any local calls!
719 area code
The 719 area code is located in the state of Colorado and covers Colorado Springs, Pueblo, Canon City, Lamar, La Junta and Alamosa. It was one of the original area codes established in 1947 when the North American Numbering Plan (NANP) went into effect. The primary purpose of this area code was to provide local telephone service for customers living within its boundaries.
Today 719 area code serves as an overlay with 303/720 (Denver Metro Area), so if you are trying to call someone in this region it depends on whether they have a landline or cell phone number. Cell phones use 720 while landlines use 719; however, some people may choose to keep their old number even if they switch from a landline to a cell phone plan – meaning that either prefix could be used for dialing them.
In addition to residential numbers, businesses also have access to this area code as well. Many companies opt for virtual phone numbers with 719 since it allows them more flexibility when managing incoming calls from different locations around the country without having multiple physical lines installed at each location. Overall, 719 is an important part of telecommunications infrastructure in the state of Colorado and provides essential services for both residents and businesses alike!
719 was created in 1988 and serves a large portion of southern Colorado. The 719 area code covers nearly 30 counties and over 1 million people within its boundaries. This particular area code has been around for more than thirty years now and has grown to be one of the most popular phone numbers in all of Colorado. It’s even been known to show up on license plates from time to time!
The popularity could be attributed to its proximity to other major metropolitan areas such as Denver (303) or Albuquerque (505). It also makes it easier for those living outside of these larger cities but still needing access to services that may not be readily available locally. The 719 area code is also often associated with mountain towns due to being situated near some fantastic ski resorts like Monarch Mountain and Wolf Creek Ski Area.
