I have noticed that Many people in this forum are not from the USA. So that leads me to this... I know enough about telephone systems and numbering outside the U.S. to fit on the end of a Hair. I can imagine there are other out there that are in the same boat. Here is my two cents worth about the phone numbers here. I hope someone will fill me in on other places. I think it will help me when I am reading over some of the notes to understand what numbers actually go where. When I dial a number here to call someone all I have to do is dial the exchange and the number assigned to them. If I dial a number outside of my area I have to dial the country code and the area code also. With cell phones it is not necessary to dial the country code within the US. Here is what I am say with the numbers. A number that contains all the elements would be 1-222-333-4444. Where '1' is the country code (you may have to correct me on this one) 222 is the Area code. Each state has its own assigned codes. 333 is the Exchange number assigned to the telco that is providing you service. 4444 would represent the individual home or business. So for me to call my neighbor I would only need to dial 333-4444, but for me to call up to the big city I will need to dial the entire string, 1-222-333-4444. That's it in a nutshell. Anyone else care to fill in more of the blanks?
