Area codes are crucial to place calls where they ought to go. Without them, there would never be enough telephone numbers to go around. Area codes can let you know where a call comes from and can also ensure that your telephone is going in the right direction. But, there are some interesting facts you might discover interesting in connection with those three digit numbers.
Though not all area codes included now have a zero or a one as the center digit, that was the practice up until the past ten years or so. Beyond that, you could tell something about a place during the original area codes. If the code had a zero as the centre number, it came from a country that initially only had one area code for the whole state. If the center number was a one, it was from one of those countries that had to have more than one for population reasons.
Along the same lines, the zero and one format was used up before the year 1995. Due to the demand for so many new numbers so quickly, new codes were used which wouldn’t have been employed in the past. The very first place code to veer away from the one and zero formulation was that the 334 code that was put to use in Alabama that year. The code 360 was put to use in Washington State very soon thereafter.
This was for people reasons and because of the fact that most phones were rotary phones then. Each number was designated by stimulation rather than simply a tone. They move the area codes such as 212. Areas with smaller populations got the higher amounts like 717, just for instance.
