§ 52.19 - Area code relief.

§ 52.19 Area code relief.

(a) State commissions may resolve matters involving the introduction of new area codes within their states. Such matters may include, but are not limited to: Directing whether area code relief will take the form of a geographic split, an overlay area code, or a boundary realignment; establishing new area code boundaries; establishing necessary dates for the implementation of area code relief plans; and directing public education efforts regarding area code changes.

(b) State commissions may perform any or all functions related to initiation and development of area code relief plans, so long as they act consistently with the guidelines enumerated in this part, and subject to paragraph (b)(2) of this section. For the purposes of this paragraph, initiation and development of area code relief planning encompasses all functions related to the implementation of new area codes that were performed by central office code administrators prior to February 8, 1996. Such functions may include: declaring that the area code relief planning process should begin; convening and conducting meetings to which the telecommunications industry and the public are invited on area code relief for a particular area code; and developing the details of a proposed area code relief plan or plans.

(1) The entity or entities designated by the Commission to serve as central office code administrator(s) shall initiate and develop area code relief plans for each area code in each state that has not notified such entity or entities, pursuant to paragraph (b)(2) of this section, that the state will handle such functions.

(2) Pursuant to paragraph (b)(1) of this section, a state commission must notify the entity or entities designated by the Commission to serve as central office code administrator(s) for its state that such state commission intends to perform matters related to initiation and development of area code relief planning efforts in its state. Notification shall be written and shall include a description of the specific functions the state commission intends to perform. Where the NANP Administrator serves as the central office code administrator, such notification must be made within 120 days of the selection of the NANP Administrator.

(c) New area codes may be introduced through the use of:

(1) A geographic area code split, which occurs when the geographic area served by an area code in which there are few or no central office codes left for assignment is split into two or more geographic parts;

(2) An area code boundary realignment, which occurs when the boundary lines between two adjacent area codes are shifted to allow the transfer of some central office codes from an area code for which central office codes remain unassigned to an area code for which few or no central office codes are left for assignment; or

(3) An all services area code overlay, which occurs when a new area code is introduced to serve the same geographic area as one or more existing area code(s), subject to the following conditions:

(i) No all services area code overlay may be implemented unless all numbering resources in the new overlay area code are assigned to those entities requesting assignment on a first-come, first-serve basis, regardless of the identity of, technology used by, or type of service provided by that entity, except to the extent that a technology- or service-specific overlay is authorized by the Commission. No group of telecommunications carriers shall be excluded from assignment of numbering resources in the existing area code, or be assigned such resources only from the all services overlay area code, based solely on that group's provision of a specific type of telecommunications service or use of a particular technology; and

(ii) No area code overlay may be implemented unless there exists, at the time of implementation, mandatory ten-digit dialing for every telephone call within and between all area codes in the geographic area covered by the overlay area code.

(4) A technology-specific or service-specific overlay, which occurs when a new area code is introduced to serve the same geographic area as one or more existing area code(s) and numbering resources in the new area code overlay are assigned to a specific technology(ies) or service(s). State commissions may not implement a technology-specific or service-specific overlay without express authority from the Commission.
