Area Code 928
Bell Laboratories and AT&T put forward an area code system in the year 1940. Despite of being introduced so early, it came into effect seven years later in the year 1947. This coding system came to be known as the NANP or North American Numbering Plan and took over Canada and the United States. NANP is the renowned agency that plays a viable role in allocating phone numbers.
In 1947, states as well as provinces that were concerned with only one area code were assigned three digit numbers as codes. These area codes had zero as their middle digit. For example, Florida’s area code came to be 305 and the area code of Connecticut came to be 203. During this period, the total number of area codes was limited to 86. States as well as provinces that were concerned with more than a single area code were allocated three digit codes. These codes had one as their middle digit. For instance, the area code of some regions of California was assigned 213 and some region of California was assigned 916. In the like manner and the area code of some regions of New York was assigned 518 and some region of New York was assigned 212. The first as well as the third digits were assigned by considering the population density of the city and of course the region that is grouped under a particular area code. The areas that were most densely populated were assigned the lowest numbers. The area including the New York City was assigned 212 whereas the surrounding areas were assigned the area code 914.
Area code 928 is the North American area code for phone numbers surrounding the Arizona areas. This area code was created in the year 2001, 23rd June after it got separated from the area code 520, chiefly because of the increase in population in Flagstaff, Yuma and Tucson. Area code 928 takes into consideration eastern, western as well as northern regions of Arizona. This area code includes area like Grand Canyon, Yuma, Prescott, Kingman and Flagstaff and also serves most of the Greenlee County. This area code serves the Arizona region of the Navajo Nation.
