==History==

The American Telephone & Telegraph Corporation originally known as Bell System developed a plan called North American Numbering Plan to assist the direct dialing calls. This plan was implemented in 1951, on November 10, 1951 the first long distance directly dialed call was made from Englewood, New Jersey to Alameda, California. Before this day the codes were used only by the long distance operators for the system which did not facilitate direct calling. By mid of 1960 almost all the major countries in North American territories had the Plan executed successfully. Initially 86 codes were used to represent the different areas; these codes were allotted to different regions of North America according to the density of the population. The regions with high density population were allotted the lower numbers while the regions with low population were allotted the higher numbers. Thus, New York was allotted 212, Los Angeles 213, Chicago 312, Dallas 214, Detroit 313 and Pittsburgh 412, while South Dakota was given (605), North Carolina (704), South Carolina (803), and the Maritime Provinces of Canada (902). <ref>[http://www.area-codes.com/area-code-history.asp]</ref><ref>[http://www.lincmad.com/map1947.html lincmad.com]</ref><ref name="link5">[http://www.squidoo.com/area_codes squidoo.com]</ref>
