Area code split (original) (raw)
In telecommunications, an area code split is the practice of introducing a new telephone area code by geographically dividing an existing numbering plan area (NPA), and assigning area codes to the resulting divisions, but retaining the existing area code only for one of the divisions. The purpose of this practice is to provide more central office prefixes, and therefore more telephone numbers, in an area with high demand for telephone services, and prevent a shortage of telephone numbers.

| dbo:abstract | In telecommunications, an area code split is the practice of introducing a new telephone area code by geographically dividing an existing numbering plan area (NPA), and assigning area codes to the resulting divisions, but retaining the existing area code only for one of the divisions. The purpose of this practice is to provide more central office prefixes, and therefore more telephone numbers, in an area with high demand for telephone services, and prevent a shortage of telephone numbers. An increasing demand for telephone numbers has existed since the development of automatic telephony in the early 20th century, but was spurred especially since the 1990s, with the proliferation of fax machines, pager systems, mobile telephones, computer modems, and finally smart phones. When an area code split is implemented, the telephone numbers in the affected area are typically changed to a new area code only, but this still requires the printing of new stationery, advertisements, and signage for many customers, and the dissemination of the new area code to family, friends, and customers. Computer systems, and telephone equipment may require updates in address books, and for speed dialing. Since area code splits have substantial impact in the involved communities, and involve substantial cost in telephone plant and exchange equipment, they are planned carefully well ahead of implementation with the intent that an area is not again affected by a subsequent realignment for at least a decade. Furthermore, the new boundaries are drawn in a manner that minimizes splitting communities and should coincide with political subdivision where practical. Other geographic features, such as rivers and bodies of water, mountain ranges, or highways may serve as guides for boundary placements. Tributary toll telephone routes should also not be unduly cut, so prevent rerouting to new toll center switching systems. The area that retains the existing area code is typically the largest, or historically more established or developed place. (en) La scission d'un indicatif régional est une opération par laquelle le territoire d'un indicatif régional est séparé en deux, une partie conservant l'indicatif régional original et l'autre obtenant un nouvel indicatif régional. Cette opération est faite lorsque la demande pour de nouveaux numéros de téléphone dans l'indicatif régional original ne peut pas être satisfaite à cause d'un épuisement des numéros de téléphone disponibles. Cette pratique est courante dans le Plan de numérotation nord-américain. Une autre façon de régler le problème d'épuisement des numéros de téléphone dans un indicatif régional est le chevauchement d'un indicatif régional. (fr) |
