P-100, SUB 137c Clerk's Office N.C. Utilities Commission BEFORE THE NORTH CAROLINA UTILITIES COMMISSION In the Matter of ) NORTH CAROLINA TELECOMMUNICATIONS Area Code Relief for North Carolina's ) INDUSTRY TASK FORCE PROPOSED ORDER 336 Numbering Plan Area ) APPROVING OVERLAY OPTION TO PROVIDE ) AREA CODE RELIEF BY THE COMMISSION: In this Order, the Commission will address the issue of area code relief for North Carolina area code 336. For all of the reasons set forth below, the Commission concludes that a distributed overlay should be adopted to relieve area code 336 as have been previously implemented in area codes 704 and 919. The schedule for full implementation of the overlay in the 336 area code is yet to be determined by the Commission. Although the relief mechanism selected for the 336 numbering plan area (NPA) is the overlay, the Commission stresses that its goal and intent is to prolong the service life of the 336 NPA by extensive conservation measures (specifically thousands-block number pooling), and thereby postpone for as long as possible the use of the new overlay area code as well as mandatory 10-digit local dialing. While there are certainly disadvantages and inconveniences associated with both a geographic split and an overlay, the Commission concludes that the distributed overlay relief method will be least inconvenient and burdensome for consumers, while providing the most significant and long-lasting relief to the area code. That decided, the Commission wishes to strongly emphasize the fact that it will continue to: (1) vigorously pursue the benefits of its number reclamation activities in the NPA; (2) carefully review assignment and utilization data from the North American Numbering Plan Administrator (NANPA) in the 336 NPA to ensure that conservation measures are being observed; and (3) pursue thousands-block number pooling to achieve all possible numbering resource management benefits applicable to the 336 NPA. The Commission will continue to stress the conservation of numbering resources as a major requirement due to the current demand for numbering resources occurring nationwide, as well as what is being experienced within the State of North Carolina. The Commission has requested, but not yet received from the Federal Communications Commission (FCC), delegated authority for thousands-block number pooling in the 336 NPA. It is the Commission's intent, once this authority is received, to implement thousands-block pooling in the 336 NPA as soon as practical in order to extend the life of that NPA to the maximum extent possible. The Commission will issue an Order in the near future addressing the implementation of thousands-block pooling in the 336 NPA. All industry participants are directed to cooperate in and actively promote this endeavor. BACKGROUND An area code is a necessary part of routing calls to their proper destination. When an area code is combined with the second three digits of the telephone number (called the NXX code or Central Office code), a "geographic address" is formed that is used to route calls through fhe public switched telephone network. The first six digits "tell" the call generally where to go, and the final four digits identify the specific individual customer. For example, the main telephone number of the North Carolina Utilities Commission is 919-733-4249. 919 is the area code, 733 is the NXX code or Central Office code, and 4249 is the line number identifying the specific customer receiving the call. North Carolina currently has eight area codes assigned to specific geographic areas of the state, including the 980 NPA code that overlays the 704 geographic area and the 984 NPA code that will overlay the 919 geographic area. Area code exhaust occurs when nearly all of the NXX codes in a given area code have been assigned to telecommunications service providers, even if individual line numbers within the NXX codes have not been assigned to customers. Typically there are 792 NXX codes available for assignment to telephone companies in an area code. Each NXX code has approximately 10,000 line numbers available for assignment to individual customers. Service providers must have the NXX codes assigned to them because the combination of the area code and the NXX code is used to route calls through the public switched telephone network in the North American Numbering Plan (NANP). Some companies also use the NXX code for billing purposes. NXX codes are associated with particular geographic areas, or "rate centers," in an area code. Telephone companies base charges for calls on the distance between the rate center where a call originates and the rate center where the call terminates. These companies obtain an NXX code in each of the identified geographic areas or "rate centers" in a particular area where they wish to provide service. In the past, local telephone service in any given area was provided by one monopoly carrier, such as BellSouth, Carolina Telephone & Telegraph Company, or GTE,1 and the requirement that the telephone company obtain an NXX code for each rate center in an area where it provided service did not strain the supply of NXX codes. Now, however, with the advent of competition in the local telephone service market, there can be several telephone companies providing service in a given area, and each one must obtain an NXX code for each rate center in that area. This change has caused a shortage in the supply of NXX codes. 1 GTE South, Incorporated is currently known as Verizon South, Incorporated. Verizon is part of the affiliated telephone companies of Bell Atlantic Corporation, collectively doing business as Verizon Communications. When almost all of the NXX codes in an area code are assigned to telephone companies, a new area code must be implemented. New area codes usually are implemented in one of two ways. First, they can be implemented through a geographic split, in which the geographic area using an existing area code is split into two parts, and roughly half of the telephone customers continue to be served through the existing area code and half must change to a new area code. Second, new area codes can be implemented through an area code overlay, in which the new area code covers the same geographic area as an existing code, but new customers in that area will be assigned to the new, or overlayed, area code. The FCC has required that there be ten-digit dialing between and within area codes in the geographic area covered by an area code overlay. This means that every local call, even if it is a call to a customer with the same area code as the caller, must be dialed with ten digits. AREA CODE 336 On September 7, 2000, NeuStar, Inc., in its role as the North American Numbering Plan Administrator (NANPA) and acting on behalf of the North Carolina telecommunications industry (Industry), filed a petition with the Commission seeking approval of the consensus Industry recommendation that an all-services distributed overlay be implemented as the relief plan for the 336 NPA. NANPA submitted its recommendation to the Commission based upon NANPA's projections that absent NPA relief, the supply of central office codes (NXX codes) for the 336 NPA would exhaust during the fourth quarter of 2002. This recommendation was developed at an Industry meeting held in Greensboro, North Carolina on July 27, 2000, where participants2 considered several alternatives to furnish relief before exhaust of 336, including an all- services distributed overlay and three different geographic splits. More specifically, the participants considered the following alternatives: Alternative 1 - Distributed Overlay: A new NPA code would be assigned to the same geographic area as the existing 336 NPA. Customers would retain their current telephone numbers; however, ten digit local dialing by all customers between and within area codes in the area covered by the new code would be required. Codes in the overlay NPA will be assigned upon request with the effective date of the new area code. At exhaust of the 336 NPA, all code assignments will be made in the new overlay area code. Alternative 1 has a projected life of 9 years. Alternative 2 - Geographic split (Winston Salem, Greensboro and High Point): The split boundary line runs around the three rate centers creating a "circle." Area A is Northeast of the split line and Area B is Southwest of the split line.
