Where is Area Code 423?

It is a telephonic area code that is used for Tennessee within the United States of America planned by the Numbering Plan method that is part of North America. It covers two separate areas in the eastern region of Tennessee that are separated by the area code 865.

The code 423 covers the cities of major importance: Bristol, Greenville, Morristown and Kingsport which is known as the Tri-cities region of northwestern Tennessee. There are also the South cities Cleveland and Chattanooga are included in the area code.

In the beginning, 901 was an area code that was created by the Numbering Planning system in North America under the single numbering plan (NPA) in 1947. After seven year, it was restricted only to West of Tennessee while an area code of 615 began to be used in the eastern part of Tennessee in 1954.

In 1995, just 41 years after, an growing necessity to provide telephone numbers prompted the number 423 as the area code. The eastern regions of the area code, together with Chattanooga as well as the Tri-Cities and Knoxville received a an area code of 423 that was newly created.

The boundary line separating 615 and the area code 423 abruptly needed to cross the line between two zones: Central as well as Eastern Time zones. The 423 area code represented the part in Tennessee located in the Eastern Time zone.

The state eventually got 3 area codes, which were then abruptly joined with Tennessee’s Traditional Grand Division of Tennessee. Three area codes, 901 and 615 were used to serve the Western portion of Tennessee while 615 served those in the Middle of Tennessee and new area code 423 was used to serve the eastern part of Tennessee.

The system of region code allocation was intended to last for the long haul for the Regulatory Authority of Tennessee. In only three years, the area code 423 was destined to be exhausted due to an increase of pager and telephone users, especially within Chattanooga in Chattanooga and Knoxville.

In the end that the creation of a new area code for Tennessee’s Eastern region of Tennessee was apparent. It would make it difficult for numerous business and users to change the numbers two times within one decade. This is what brought the the area code 865 into being. This new code is for large areas of the Central portion of Tennessee and Knoxville which was put into effect on November 1st, 1999. Eastern Tennessee followed the dialing from 423 up to 22nd April 2000.

In the time division plans were being administered the results showed that there was a large traffic in Tri-cities following Knoxville to the area code 865, but not been enough people using the area code of its own. Therefore the authority that regulates Tennessee is faced with two options, or a split approach that will result in two area codes of 423 non-contagious sections, or 865 would need to be overlapping with the eastern part of Tennessee.

The other option was put into play as a result of the overlap, there was some resistance to dial methods using 10-digit numbers. In general, Knoxville being the largest city in the state was slated to maintain the area code 423; however, the regulatory authority for Tennessee submitted a request to use 865 on the keyboard that is alphanumeric, 423 looks like volunteers. (VOL) is used as an epithet of Tennessee University.

This led to the development in one of the very few area codes that would not be infectious, as 423 is surrounded by 865 throughout the entire region, excluding east. The NPA was the first to make a calculation that changed 423’s shape and remain in place until the year 2010. But, once the mix of numbers became effective within the Southern region of 2002 the NPA has a idea of 423 remaining in a non-infectious state until 2027.
