What are Geographic Numbers – Overview
Geographic numbers are telephone numbers that are associated with a particular geographic location. These numbers are used to identify the location of a caller and provide valuable information about where a call is originating from. In this article, we will explore the history of geographic numbers, their use, popular geographic codes in the USA and UK, area code time zone, benefits of the geographic numbering system, types of the geographic numbering system, the future of geographic numbers, how they work and area code location.
The History of Geographic Numbers
Geographic numbers have been in use since the early days of the telephone network. In the early 20th century, telephone numbers were typically assigned based on the location of the telephone exchange that served a particular area. This meant that each exchange had its own unique set of numbers, and callers could be identified by their exchange name and number.
In the 1940s, the North American Numbering Plan (NANP) was introduced in the United States, which standardized the way that telephone numbers were assigned and allowed for nationwide direct dialing. The NANP established a system of three-digit area codes that identified the location of the caller, followed by a seven-digit telephone number.
In the United Kingdom, a similar system was introduced in the 1950s, with the introduction of the Director Telephone System. This system used a three-letter exchange name followed by four digits to identify individual telephone numbers.
The Use of Geographic Numbers
Geographic numbers are used for a variety of purposes. One of the most common uses is to establish a local presence in a particular area. Businesses, for example, may purchase a geographic number in a particular area code to make it easier for local customers to contact them.
Geographic numbers are also used to identify the location of a caller in emergency situations. When a caller dials emergency services such as 911 or 999, the call is routed to the appropriate emergency services center based on the caller’s location.
Popular Geographic Codes in the USA and UK
In the United States, area codes are assigned based on the location of the caller. Some of the most popular area codes in the USA include:
212: New York City
310: Los Angeles
312: Chicago
415: San Francisco
617: Boston
786: Miami
In the United Kingdom, area codes are assigned based on the location of the telephone exchange. Some of the most popular area codes in the UK include:
020: London
0161: Manchester
0121: Birmingham
0113: Leeds
0141: Glasgow
0131: Edinburgh
Area Code Time Zone
In the United States, area codes are also associated with specific time zones. For example, area codes that begin with the number “2” are associated with the Eastern time zone, while area codes that begin with the number “7” are associated with the Pacific time zone. There 916 area code is also a popular area code 916 area code time zone is fixed according to its radius.
Benefits of the Geographic Numbering System
One of the key benefits of the geographic numbering system is that it allows for easy identification of the location of a caller. This can be particularly useful in emergency situations, where knowing the caller’s location can be critical.
The geographic numbering system also allows businesses to establish a local presence in a particular area. This can be useful for companies that operate in multiple locations and want to make it easier for customers to contact them.
Types of Geographic Numbers
There are several different types of geographic numbers, including:
Standard Geographic Numbers: These are traditional geographic numbers that are associated with a particular geographic location. They are typically used for landlines and are assigned based on the location of the telephone exchange.
Non-Geographic Numbers: These are numbers that are not associated with a particular geographic location. Instead, they are assigned to a particular service or function. Examples of non-geographic numbers include toll-free numbers (e.g., 1-800 numbers), premium rate numbers (which are used for services such as adult chat lines), and virtual phone numbers (which allow businesses to have a local presence in multiple locations).
The Future of Geographic Numbers
As technology continues to evolve, the way that geographic numbers are used is likely to change as well. One potential development is the increased use of virtual phone numbers, which allow businesses to have a local presence in multiple locations without the need for a physical presence.
Another development is the use of location-based services, which can provide additional information about a caller’s location. For example, GPS-enabled smartphones can provide precise location information that can be used to direct emergency services to the caller’s location.
How Do Geographic Numbers Work?
Geographic numbers are assigned by the local telecommunications provider. When a call is made to a geographic number, the call is routed to the local exchange that serves the area associated with the number. The call is then routed to the appropriate telephone number based on the seven-digit telephone number associated with the geographic number.
Area Code Location
The location associated with a particular area code can vary depending on the geographic area. For example, area code 212 is associated with New York City, but it also covers some parts of the surrounding area. Similarly, area code 310 is associated with Los Angeles, but it also covers some parts of the surrounding area.
Conclusion
Geographic numbers have been an important part of the telephone network for many years. They provide valuable information about the location of a caller and allow businesses to establish a local presence in a particular area. As technology continues to evolve, the way that geographic numbers are used is likely to change as well, but they will continue to play an important role in the telecommunications industry.
