The numerical sequence ’02’ functions as a geographic identifier within the national telephone numbering plan. When dialed before a local number, it directs a call to a specific region. For instance, dialing ’02’ followed by an eight-digit number connects the caller to a landline within a designated area.

This code is essential for efficient telecommunications infrastructure, ensuring calls are routed correctly across the network. Its introduction streamlined long-distance dialing processes, removing ambiguity in destination selection. Furthermore, its continued use maintains a structured and organized system for telephony within the specified area.

The numerical designation identifies a specific geographic region within the North American Numbering Plan. It serves as a prefix for telephone numbers originating from a particular area, enabling the routing of calls to the correct destination. For example, a telephone number using this designation would begin with 914, followed by a seven-digit subscriber number.

This identifier is essential for telecommunications infrastructure and provides a foundation for local communication networks. Its introduction facilitated the growth of telephone services in the designated region and allowed for efficient management of telephone resources. Its historical context reflects the expansion of telephone networks and the increasing demand for telecommunication services in the latter half of the 20th century.

513 designates a specific geographic region within the North American Numbering Plan (NANP). This three-digit numerical prefix allows for telephone calls to be routed to southwestern Ohio, primarily encompassing the Cincinnati metropolitan area. For example, a phone number using this designator would begin 513-XXX-XXXX.

The aforementioned numerical identifier is crucial for efficient telecommunications infrastructure. Its implementation ensures proper call delivery and facilitates regional identification. Initially established in 1947 as one of the original area codes, its continued use provides a historical link to the development of the modern telephone network and represents a consistent method for directing calls within its designated service area.

A numbering plan area, designated numerically, serves as a geographic identifier within a telecommunications network. This three-digit code precedes the seven-digit telephone number and is essential for routing calls to the correct destination. For example, a call placed from outside a designated area requires dialing this code before the local number.

These numerical designators streamline telecommunications by dividing service areas and preventing number duplication. Their implementation facilitated the expansion of telephone networks and efficient call routing. Historical context reveals their creation as a response to growing demand and the need for standardized routing protocols. The system allows for manageable growth and adaptation to evolving telecommunications technologies.
