What are Area Codes? 

Area codes are three-digit codes in the telephone numbering system that identify specific geographic regions. They play a crucial role in routing calls through telephone networks to their intended destinations. When making calls, these area codes must be dialed along with the subscriber’s phone number to ensure connectivity to the desired location.

These codes are assigned based on the size and population density of an area. Depending on area size, some states have only one area code, and some have multiple area codes to serve the telephone service. For example, in the USA, twelve states have only one area code: Alaska, North Dakota, Delaware, Maine, South Dakota, Hawaii, Rhode Island, Idaho, New Hampshire, Montana, Vermont, and Wyoming. In contrast, larger states may have multiple area codes to accommodate their population.

Similarly, as the population grows, new area codes are introduced either through splits or overlays to meet the increasing demand for phone numbers.

History Behind Area Codes

In the mid-20th century, area codes were introduced after the first phone was invented to manage telephone networks. In the beginning, phone calls were handled by human operators who worked at the telephone switchboard. 

Area codes were three-digit numbers assigned to the different geographic regions. The first digit represents the region’s size or location relative to major cities, and the following two provide more specific locality information. 

Similarly, as the population and phone usage increase, the need for more area codes also increases. To solve this problem, the North American Numbering Plan (NANP) was developed in 1947, which assigned area codes across the United States, Canada, and certain nearby regions. Each area code was unique and different from each other to ensure that phone numbers could be dialed easily and routed to the aimed location. 

Over time, new technology has developed, and area codes have been added or split to meet the demand for phone numbers. Area codes play an important role in the telecommunication system, identifying the geographical location of phone numbers.
