‘Phoenix is the capital and most populous city of Arizona.’ It is the only state capital in America with a splendid number of population, something near about more than one million residents. It is also known as the Valley of Sun. Phoenix area codes include – 602, 480 and 623.
North American area code 602, is a state of Arizona telephone area code that covers most of the city of Phoenix. It was one of the original area codes, established in October 1947 and originally covered the entire state of Arizona until 1995, when the area code 520, was found as the state’s second area code.’ Since there was an increased demand for telephone communications, fax exchange and many more, the area code 520 was introduced because too much pressure on the area code 602, would lead to its exhaustion. However, the single area code 520, also could not solve the problem of the extreme pressure, so craving paths towards multiple area codes required a decision for an overlay. It was during that time, when a split in the geographical area was essentially established, and it came into effect from April 1, 1999. ‘ Generally, 480 served the East Valley while 623, served the West Valley. Most areas of Phoenix remained in 602, but a few areas ( such as Ahwatukee neighbourhood and parts of Maryvale ) transferred to 480 or 623. This split resulted in Phoenix becoming one of the few major cities in the nation to be split between multiple area codes. Only two cities ended with multiple area codes with this change. While this also made Phoenix one of the few major cities not to be overlaid, ten-digit dialling is now necessary for certain areas of the metro area. And it is the only million plus a populated area where seven digit dialling would still be possible.’ The popular carriers of this area code include – Quest Corporation ( being the maximum), Verizon Wireless, Sprint, Teleport America, Cingular, USA Mobility Wireless, Cricket Comm and others. The maximum percentage of carrier is Landline, and the rest is Wireless. The demographic figure under this area code is enormous, near about 1,482,780. It covers about eleven cities of Arizona, including – Carefree, Cave Creek, Fort Mcdowell, Fountain Hills, Glendale, New River, Paradise Valley, Phoenix, Scottsdale, Tempe, Tortilla Flat.
Coming to the area code, 480, ‘North American Area code 480, is a telephone area code in Arizona, serving the eastern and northern portions of Phoenix Metropolitan area. It was created on April 1, 1999, in a three-way split of area code 602, when it was apparent that the Valley if Sun, was growing too fast, for it to remain entirely in one area code. As of October 2018, area code, 480 is expected to reach exhaustion by the first quarter of 2025, but as of February 2016, there is no relief plan in place.’ Cities which fall under the area code include – Mesa, Scottsdale, Chandler, Gilbert, Tempe, Queen Creek, Higley, Cave Creek, Fountain Hills, Paradise Valley, Carefree, Rio Verde, Fort McDowell ( Maricopa), San Tan Valley, Apache Junction, Gold Canyon ( Pinal ).
Focussing on area code 623, ‘ North American area code 623, is a state of Arizona telephone area code serving most of the Western Portion of the Phoenix metropolitan area. The West Valley and the outer NorthWestern suburbs became 623, the eastern suburbs and the Phoenix neighbourhood of Ahwatukee became are code 480, and inner Phoenix remained 602.’ It was brought into effect from March 1, 1999, after the split from the parent code 602. The cities which come under the area code 623, include – Glendale, Peoria, Surprise, Avondale, Goodyear, Buckeye, Sun City, El Mirage, Tolleson, Sun City West, Litchfield Park, Waddell, New River, Wittmann, Tonopah, Cashion, Youngtown, Morristown, Luke AFB. The major carriers of this code include – Quest Corporation ( being the maximum ), Verizon Wireless, Cricket Comm, Sprint, T-mobile, Integra Telecom, Teleport America and Others.
So, it is all about the Phoenix area codes, and it can be concluded that landlines own the maximum percentage of these codes in various corporates and organisations. And due to the geographical split, there is no enormous pressure on any particular system. Due to the extreme growth of population and telephone demands, it is good and advisable for such a split to avoid trouble on any specific area code.
