Why do we need area codes?

Area codes are essential to place calls where they need 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 call is going in the right direction. For the most part, that is all that you need to know about area codes. However, there are some fun facts you might find interesting in relation to these three digit numbers.

Though not all area codes included today have a zero or a one as the center digit, that was the practice up until the last decade or so. This was for ease of dialing. Beyond that, you could tell something about a place through the original area codes. If the code had a zero as the centre number, it came from a country that originally only had one area code for the entire state. If the center number was a one, it was from one of the states that had to have more than one for population reasons.

Along the same lines, the zero and one format was used up until the year 1995. Due to the need for so many new numbers so quickly, new codes were used that would not have been employed in the past. The very first area code to veer away from the zero and one 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 shortly thereafter.

This was for people reasons and because of the fact that all phones were rotary phones then. Each number was designated by stimulation rather than just a tone. They move the area codes such as 212. Areas with smaller populations got the higher amounts like 717, just as an example.
