The Basics behind the Telephone Numbers We Use
You might be surprised to learn that the telephone company did not always use the same 10 digit system that they are currently operating on. As a matter of fact, it was only whenever telephones begin to truly overtake the system that they needed a way to be able to tell the difference in where the phone calls were coming from and where they were going.
Another thing that added to the fact that they needed to change the system was the automation that was about to take place. In the old system, they would have an operator that sat at a switchboard and manually plugged in the phone lines to connect them to each other. As a result of automating the system, they needed a way to accurately discern which calls may be connected to which numbers.
You are, no doubt familiar with the 10 digit telephone system that is now being used but taking a close look at it can actually be quite interesting. Here is a little bit about what you can learn by following along with the various parts of these area codes and telephone numbers. Understanding this can help you in a number of different ways.
The first three digits are the area code. This is the most telling part about the telephone number, because it helps you to see what part of the country that the call originated from. Most area codes are somewhat localized, especially because of all of the telephones that are now in existence. At times, an area code may span several small towns and there are rare occasions whenever it might even cross state lines. Most of the time, however, area codes are assigned to a very small area of the country and there might even be cities that have multiple area codes.
Whenever they first came up with the 10 digit numerical system, they never saw the day whenever it could be outdated. Although we are not getting close to using up all the area codes as of yet, the use of cellular telephones and the popularity of fax machines in business has used up many more of the area codes that they had considered before this time. If they end up running out of area codes, a second type of numerical system may need to be put into place in order to handle the situation.
The second set of three digits that is inside of the 10 digit telephone number help you break down even further where the call is originating from. Each area will have this code assigned to it and it is very rare that it will span more than one small area of the country. It may also help you to tell whether you are receiving a phone call from a cellular line or if it is a land-based line.
If you would like to be able to trace a telephone number back to its original caller, using all 10 digits will be necessary. You can look up the area code on one of the websites that is available on the Internet, and even find out a little bit more information about the following the next three digits. Using the entire 10 digits, however, will help you to know exactly who it was that was calling and where they were calling from.
