When Did Phone Numbers Go From 7 Digits to 10

In the early days of the telephone system, people communicated with one another by using long strings of gibberish. To make things easier for people, the numbers were assigned in a simple, sequential order. The first number in the sequence was assigned to the western coast, the second number was assigned to the eastern coast, and so on. But because people in different parts of the country used different numbers, it was difficult for them to communicate with each other.

In 1878, AT&T decided to solve this problem by assigning each number a specific purpose. The first number, called the ‘local number’, was used to identify a particular telephone. The second number, called the ‘long distance number’, was used to identify the telephone location. The third number, called the ‘subscriber number’, was used to identify the person who was speaking on the telephone.

But even with these numbers, it was still difficult for people to communicate with each other. So in 1879, AT&T decided to add another number to the system. The fourth number, called the ‘party line number’, was used to identify the telephone line. And finally, the fifth number, called the ‘line number’, was used to identify the particular call.

This system worked well for a while, but in the early days of the telephone system, people used a lot of long-distance calls. So in 1916, AT&T decided to add another number to the system. The sixth number, called the ‘local number’, was used to identify a particular telephone. The seventh number, called the ‘long distance number’, was used to identify the telephone location. The eighth number, called the ‘subscriber number’, was used to identify the person who was speaking on the telephone. And the ninth number, called the ‘party line number’, was used to identify the telephone line.
