What Is Area Codes And How Area Code Changes With Time

In the vast realm of telecommunications, area codes such as 347 area code play a pivotal role in connecting individuals across regions and defining geographical boundaries. Area codes are numerical prefixes that accompany telephone numbers, serving as identifiers for specific geographic locations. In this article, we embark on a journey to explore the intricate world of area codes, shedding light on the distinctive features of the enigmatic 347 area code.

History of Area Codes

A. Early telephone systems and the need for a numbering system

As telephone systems emerged and evolved, it became evident that a standardized numbering system was essential. In the early days of telephony, operators manually connected calls through switchboards, requiring a system that would differentiate between different phone lines. The need for a numbering system became even more pressing as telephone networks expanded and the demand for efficient communication surged.

B. Development and implementation of area codes

The development of area codes was a significant breakthrough in the evolution of telecommunications. In the mid-20th century, the North American Numbering Plan (NANP) was introduced to streamline and organize telephone networks. The NANP established a three-digit format for area codes, simplifying the routing of calls and enabling effective communication across the United States and Canada.

C. Changes and expansions over the years

As population growth and technological advancements skyrocketed, the demand for telephone services surged. To accommodate this growth, area codes underwent constant changes and expansions. New area codes were introduced, and existing ones were divided or overlaid to ensure an ample supply of phone numbers. These changes were crucial for the seamless operation of telecommunication networks and the uninterrupted flow of communication.

Structure of Area Codes

A. Explanation of the numbering pattern and format

Area codes generally consist of three digits, immediately followed by a seven-digit local telephone number. This combination provides a unique identifier for each telephone line within a specific geographic area. However, it’s important to note that area code formats may differ across countries and regions.

B. Breakdown of the components within an area code

Within an area code, each digit holds significance. In North America, the first digit often represents the proximity of the region to major population centers. Lower numbers are typically assigned to areas closer to densely populated cities. The subsequent two digits further narrow down the geographic location within that region, allowing for more specific identification.

C. Examples of different area code formats in different countries

While the three-digit format is widely used in North America, area code formats vary worldwide. For instance, the United Kingdom employs a four- to six-digit area code system, offering a higher level of granularity for geographic identification. In contrast, Australia’s area codes typically consist of two digits. Familiarizing oneself with these variations is crucial for seamless communication across international borders.

Purpose and Function of Area Codes

A. Geographical identification and regional organization

The primary purpose of area codes is to provide geographical identification. By recognizing the area code associated with a telephone number, callers can quickly ascertain the general location of the person they are dialing. This function enables efficient regional organization and allocation of telecommunication resources.

B. Routing calls within a specific area

Area codes play a vital role in routing calls within a specific geographic area. When dialing a number within the same area code, callers need only input the seven-digit local number, as the area code is assumed. This simplifies the dialing process and ensures that calls are accurately directed within the desired local area.

C. Differentiation of local and long-distance calls

Area codes are instrumental in differentiating between local and long-distance calls. By recognizing the area code, callers can determine whether a call falls within their local calling area or if it requires long-distance communication. This differentiation is crucial in managing calling costs and understanding the scope of the call. Local calls within the same area code are often included in calling plans or charged at a lower rate, while long-distance calls may incur additional charges or require specific long-distance service providers.

D. Impact on telecommunication services and infrastructure

The allocation and management of area codes have a significant impact on telecommunication services and infrastructure. Telecommunication providers must carefully plan and administer area codes to ensure an adequate supply of phone numbers and efficient call routing. This involves collaboration with regulatory bodies and industry stakeholders to allocate area codes based on population density, geographic boundaries, and projected growth.

Additionally, area codes influence the design and maintenance of telecommunication infrastructure. Network switches and routing systems are programmed to recognize and route calls based on area codes. The efficient routing of calls within a specific area is essential to minimize congestion, ensure call quality, and optimize the use of telecommunication resources.

E. Area Code 347 Location

Now, let’s shine the spotlight on the intriguing 347 area code. This area code serves parts of New York City, including the boroughs of Brooklyn, Queens, Staten Island, the Bronx, and Manhattan. Introduced in 1999, the 347 area code was created as an overlay for the existing 718 area code to meet the increasing demand for phone numbers in the region.


Area codes serve as essential identifiers within the vast telecommunication network, facilitating communication across geographical boundaries. Their history dates back to the early days of telephone systems and has evolved with the demands of a rapidly changing world. Understanding the structure, purpose, and function of area codes allows us to navigate the telecommunications landscape seamlessly.

The 347 area code, among many others, plays a vital role in connecting individuals within specific regions of New York City. Through the allocation and management of area codes, telecommunication services and infrastructure continue to support the growing demands of our interconnected world. So, the next time you dial a number and encounter an area code, remember the fascinating story behind those three digits and their role in enabling communication and bridging distances.
