The United States is divided into regions and area codes, each of which corresponds to a particular geographic area. There are only a limited number of area codes in each state, so there is not a universal area code. Many states have multiple area codes, though. As the US population continues to increase, the need for area codes increased. This resulted in more telephone numbers, making it possible to offer more advanced services. In the past, there were 77 different area codes.
In 1947, the Bell System introduced the concept of area codes, or phone numbers assigned to a specific geographic area. Since the United States is a country with around 300 million people, each area code has its own unique telephone number. The  are a three-digit number that is fixed in length. The USA area name is important because human memory is not great for memorizing long lists. The average human can remember only 5 to nine digits in their short-term memory.

The Southern United States is known as the South, and includes sixteen states and 115 area codes. Famous area codes in this region include 512 (Austin), and 281 (Houston).
The public service commission decides whether or not to change the USA area codes. If this is the case, the Public Service Commission will decide on the method to implement the new area codes. It will order a transition period during which customers are informed about the new area codes, and they will be provided with education. 

A transition period will help customers avoid any confusion when dialing a new area code. This can also reduce costs for both businesses and consumers.
The United States area code system was established in 1947. The numbering plan was designed to unify the numbering system across North America. In 1947, two companies, Bell Laboratories and AT&T, issued area codes for cities. By the mid-60s, area codes were widely used in all US cities. Initially, the area code system was only used in cities with high populations, but it was widely implemented by the mid-70s.
