Area Code 972
Bell Laboratories and AT&T introduced an area code system in the year 1940. Thought it was established quite early, yet it came into effect too late in the year 1947. The area c code system was popularly known as NANP or North American Numbering Plan and it took into consideration Canada as well as the United States. NANP is referred to as the well admired agency that plays a leading role in assigning phone numbers.
In 1947, states as well as provinces having one area code were offered three digit numbers as area codes with zero as their mid number. At this point of time, the total number of area codes was limited to 86. States as well as provinces having more than a single area code were offered three digit codes as area codes with one as their mid number. The first as well as the third digits were assigned after taking into consideration the overall population of the city as well as the region grouped under a particular area code. The areas that were most densely populated were offered the lowest numbers.
469, 214 and of course 972 are believed to be the North American telephone area codes for numbers surrounding the Dallas region, Texas, the United States. Area code 214 is believed to be the initial area codes introduced in the year 1947, October. Area code 972 was formed in the year 1996, 14th of September after the suburban areas of Dallas got separated from the city proper of Dallas. However, this area code was transformed into an overlay after the area code 469 was established in 1999, 1st of July. The out come was three area codes that overlaid the same region.
