Area codes are essential to place calls where they ought to go. Without them, there would never be enough phone numbers to go around. Area codes can let you know where a call comes from and can also ensure that your call is going in the right direction. For the most part, that is all that you have to know about area codes. But, there are some fun facts you may find interesting in relation to those three digit numbers.
Though not all area codes added 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 an area during the original area codes. If the code had a zero as the centre number, it came from a state that initially only had one area code for the entire state. If the middle 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 that wouldn’t have been employed in the past. The very first area code to veer away from the one and zero formula was the 334 code that was put into use in Alabama that year. The code 360 was put into use in Washington State very soon thereafter.
When first put into place, the area code numbering plan implemented amounts according to difficulty. This was for population reasons and due to the fact that all phones were rotary phones at that time. Each number was designated by stimulation rather than simply a tone. Highly populated areas obviously had the most calls going out. They go the area codes such as 212. Areas with smaller populations got the higher numbers like 717, just for instance.
