PURPOSE AND SCOPE This document specifies guidelines and procedures that address the North American Numbering Plan Numbering Resource Utilization/Forecast (NRUF) Report. Service Providers are required to submit an NRUF Report to provide both utilization and forecast data for numbering resources from geographic numbering plan area (NPA) codes@ including numbering resources in the PCS 5YY NXX (e.g. NPA 500) and 9YY Non-Geographic NPAs.1@ 2 3 This information is used by the North American Numbering Plan Administrator (NANPA) to project the exhaust date of individual NPAs as well as the life span of the North American Numbering Plan (NANP). The NRUF Report addresses the need to collect both utilization and forecast- data in a single tool. Along with forecasting NPA and NANP exhaust@ the NRUF Report also assists in assessing the utilization of numbering resources within an NPA code for the potential application of numbering resource optimization measures. This data provides valuable insight to the impact of various numbering resource optimization measures that may be implemented to extend the life of a NPA code. In addition@ utilization data collected via the NRUF Report may also serve in the audit process of an individual service provider's usage of numbering resources. These guidelines are expected to apply throughout the NANP area subject to the appropriate regulatory and governmental procedures and constraints within each NANP country. 1 This is a requirement of the Federal Communications Commission (FCC) in the first Numbering Resource Optimization Report and Order@ FCC 00-104. 2 See Section 4.1.1 of the CO Code (NXX) Assignment Guidelines (ATIS-0300051). 3 Public Notice@ DA 01-1409@ released June 11@ 2001@ clarified that 500 and 900 NPAs are covered by Numbering Resource Optimization@ CC Docket No. 99-200@ Report and Order and Further Notice of Proposed Rulemaking@ 15 FCC Rcd 7574 (2000) (NRO Order).
