(a) Local number portability administration shall comply with the recommendations of the North American Numbering Council (NANC) as set forth in the report to the Commission prepared by the NANC's Local Number Portability Administration Selection Working Group, dated April 25, 1997 (Working Group Report) and its appendices. Except that: Sections 7.8 and 7.10 of Appendix D and the following portions of Appendix E: Section 7, Issue Statement I of Appendix A, and Appendix B in the Working Group Report are not incorporated herein.

(b) In addition to the requirements set forth in the Working Group Report, the following requirements are established:

(1) Each designated N–1 carrier (as described in the Working Group Report) is responsible for ensuring number portability queries are performed on a N–1 basis where “N” is the entity terminating the call to the end user, or a network provider contracted by the entity to provide tandem access, unless another carrier has already performed the query;

(2) If a telecommunictions carrier transmits a telephone call to a local exchange carrier's switch that contains any ported numbers, and the telecommunications carrier has failed to perform a database query to determine if the telephone number has been ported to another local exchange carrier, the local exchange carrier may block the unqueried call only if performing the database query is likely to impair network reliability;

(3) The regional limited liability companies (LLCs), already established by telecommunications carriers in each of the original Bell Operating Company regions, shall manage and oversee the local number portability administrators, subject to review by the NANC, but only on an interim basis, until the conclusion of a rulemaking to examine the issue of local number portability administrator oversight and management and the question of whether the LLCs should continue to act in this capacity; and

(4) The NANC shall provide ongoing oversight of number portability administration, including oversight of the regional LLCs, subject to Commission review. Parties shall attempt to resolve issues regarding number portability deployment among themselves and, if necessary, under the auspices of the NANC. If any party objects to the NANC's proposed resolution, the NANC shall issue a written report summarizing the positions of the parties and the basis for the recommendation adopted by the NANC. The NANC Chair shall submit its proposed resolution of the dispuited issue to the Chief of the Wireline Competition Bureau as a recommendation for Commission review. The Chief of the Wireline Competition Bureau will place the NANC's proposed resolution on public notice. Recommendations adopted by the NANC and forwarded to the Bureau may be implemented by the parties pending review of the recommendation. Within 90 days of the conclusion of the comment cycle, the Chief of the Wireline Competition Bureau may issue an order adopting, modifying, or rejecting the recommendation. If the Chief does not act within 90 days of the conclusion of the comment cycle, the recommendation will be deemed to have been adopted by the Bureau.

§ 52.32 - Allocation of the shared costs of long-term number portability.

(a) The local number portability administrator, as defined in § 52.21(h), of each regional database, as defined in § 52.21(1), shall recover the shared costs of long-term number portability attributable to that regional database from all telecommunications carriers providing telecommunications service in areas that regional database serves. Pursuant to its duties under § 52.26, the local number portability administrator shall collect sufficient revenues to fund the operation of the regional database by:

(1) Assessing a $100 yearly contribution on each telecommunications carrier identified in paragraph (a) introductory text that has no intrastate, interstate, or international end-user telecommunications revenue derived from providing telecommunications service in the areas that regional database serves, and

(2) Assessing on each of the other telecommunications carriers providing telecommunications service in areas that regional database serves, a charge that recovers the remaining shared costs of long-term number portability attributable to that regional database in proportion to the ratio of:

(i) The sum of the intrastate, interstate, and international end-user telecommunications revenues that such telecommunications carrier derives from providing telecommunications service in the areas that regional database serves, ii) to the sum of the intrastate, interstate, and international end-user telecommunications revenues that all telecommunications carriers derive from providing telecommunications service in the areas that regional database serves.

(b) All telecommunications carriers providing service in the United States shall complete and submit a “Telecommunications Reporting Worksheet” (as published by the Commission in the Federal Register), which sets forth the information needed to calculate contributions referred to in paragraph (a) of this section. The worksheet shall be certified to by an officer of the contributor, and subject to verification by the Commission or the administrator at the discretion of the Commission. The Chief of the Wireline Competition Bureau may waive, reduce, modify, or eliminate contributor reporting requirements that prove unnecessary and require additional reporting requirements that the Bureau deems necessary to the sound and efficient administration of long-term number portability.

(c) Local number portability administrators shall keep all data obtained from contributors confidential and shall not disclose such data in company-specific form unless directed to do so by the Commission. Subject to any restrictions imposed by the Chief of the Wireline Competition Bureau, the local number portability administrators may share data obtained from carriers with the administrators of the universal service support mechanism (See 47 CFR 54.701 of this chapter), the TRS Fund (See 47 CFR 64.604(c)(4)(iii)(H) of this chapter), and the North American Numbering Plan cost recovery (See 47 CFR 52.16). The local number portability administrators shall keep confidential all data obtained from other administrators. The administrators shall use such data, from carriers or administrators, only for purposes of administering local number portability. The Commission shall have access to all data reported to the Administrator. Contributors may make requests for Commission nondisclosure of company-specific revenue information under § 0.459 of this chapter by so indicating on the Telecommunications Reporting Worksheet at the time that the subject data are submitted. The Commission shall make all decisions regarding nondisclosure of company-specific information.

(d) Once a telecommunications carrier has been allocated, pursuant to paragraph (a)(1) or (a)(2) of this section, its portion of the shared costs of long-term number portability attributable to a regional database, the carrier shall treat that portion as a carrier-specific cost directly related to providing number portability.

[63 FR 35160, June 29, 1998, as amended at 64 FR 41331, July 30, 1999; 67 FR 13226, Mar. 21, 2002; 73 FR 9481, Feb. 21, 2008; 80 FR 66479, Oct. 29, 2015]

§ 52.33 - Recovery of carrier-specific costs directly related to providing long-term number portability.

(a) Incumbent local exchange carriers may recover their carrier-specific costs directly related to providing long-term number portability by establishing in tariffs filed with the Federal Communications Commission a monthly number-portability charge, as specified in paragraph (a)(1) of this section, a number portability query-service charge, as specified in paragraph (a)(2) of this section, and a monthly number-portability query/administration charge, as specified in paragraph (a)(3) of this section.

(1) The monthly number-portability charge may take effect no earlier than February 1, 1999, on a date the incumbent local exchange carrier selects, and may end no later than 5 five years after the incumbent local exchange carrier's monthly number-portability charge takes effect.

(i) An incumbent local exchange carrier may assess each end user it serves in the 100 largest metropolitan statistical areas, and each end user it serves from a number-portability-capable switch outside the 100 largest metropolitan statistical areas, one monthly number-portability charge per line except that:

(A) One PBX trunk shall receive nine monthly number-portability charges.

(B) One PRI ISDN line shall receive five monthly number-portability charges.

(C) Lifeline Assistance Program customers shall not receive the monthly number-portability charge.

(ii) An incumbent local exchange carrier may assess on carriers that purchase the incumbent local exchange carrier's switching ports as unbundled network elements under section 251 of the Communications Act, and/or Feature Group A access lines, and resellers of the incumbent local exchange carrier's local service, the same charges as described in paragraph (a)(1)(i) of this section, as if the incumbent local exchange carrier were serving those carriers' end users.

(iii) An incumbent local exchange carrier may not assess a monthly number-portability charge for local loops carriers purchase as unbundled network elements under section 251.

(iv) The incumbent local exchange carrier shall levelize the monthly number-portability charge over five years by setting a rate for the charge at which the present value of the revenue recovered by the charge does not exceed the present value of the cost being recovered, using a discount rate equal to the rate of return on investment which the Commission has prescribed for interstate access services pursuant to Part 65 of the Commission's Rules.

(2) The number portability query-service charge may recover only carrier-specific costs directly related to providing long-term number portability that the incumbent local exchange carrier incurs to provide long-term number portability query service to carriers on a prearranged and default basis.

(3) An incumbent local exchange carrier serving an area outside the 100 largest metropolitan statistical areas that is not number-portability capable but that participates in an extended area service calling plan with any one of the 100 largest metropolitan statistical areas or with an adjacent number portability-capable local exchange carrier may assess each end user it serves one monthly number-portability query/administration charge per line to recover the costs of queries, as specified in paragraph (a)(2) of this section, and carrier-specific costs directly related to the carrier's allocated share of the regional local number portability administrator's costs, except that per-line monthly number-portability query/administration charges shall be assigned as specified in paragraph (a)(1) of this section with respect to monthly number-portability charges.

(i) Such incumbent local exchange carriers may assess a separate monthly number-portability charge as specified in paragraph (a)(1) of this section but such charge may recover only the costs incurred to implement number portability functionality and shall not include costs recovered through the monthly number-portability query/administration charge.

(ii) The monthly number-portability query/administration charge may end no later than five years after the incumbent local exchange carrier's monthly number-portability query/administration charge takes effect. The monthly number-portability query/administration charge may be collected over a different five-year period than the monthly number-portability charge. These five-year periods may run either consecutively or concurrently, in whole or in part.

(b) All telecommunications carriers other than incumbent local exchange carriers may recover their number portability costs in any manner consistent with applicable state and federal laws and regulations.

§ 52.34 - Obligations regarding local number porting to and from interconnected VoIP or Internet-based TRS providers.

(a) An interconnected VoIP or VRS or IP Relay provider must facilitate an end-user customer's or a Registered Internet-based TRS User's valid number portability request, as it is defined in this subpart, either to or from a telecommunications carrier or an interconnected VoIP or VRS or IP Relay provider. “Facilitate” is defined as the interconnected VoIP or VRS or IP Relay provider's affirmative legal obligation to take all steps necessary to initiate or allow a port-in or port-out itself or through the telecommunications carriers, if any, that it relies on to obtain numbering resources, subject to a valid port request, without unreasonable delay or unreasonable procedures that have the effect of delaying or denying porting of the NANP-based telephone number.

(b) An interconnected VoIP or VRS or IP Relay provider may not enter into any agreement that would prohibit an end-user customer or a Registered Internet-based TRS User from porting between interconnected VoIP or VRS or IP Relay providers, or to or from a telecommunications carrier.

(c) Telecommunications carriers must facilitate an end-user customer's valid number portability request either to or from an interconnected VoIP or VRS or IP Relay provider. “Facilitate” is defined as the telecommunication carrier's affirmative legal obligation to take all steps necessary to initiate or allow a port-in or port-out itself, subject to a valid port request, without unreasonable delay or unreasonable procedures that have the effect of delaying or denying porting of the NANP-based telephone number.

§ 52.35 - Porting Intervals.

(a) All telecommunications carriers required by the Commission to port telephone numbers must complete a simple wireline-to-wireline or simple intermodal port request within one business day unless a longer period is requested by the new provider or by the customer. The traditional work week of Monday through Friday represents mandatory business days and 8 a.m. to 5 p.m. represents minimum business hours, excluding the current service provider's company-defined holidays. An accurate and complete Local Service Request (LSR) must be received by the current service provider between 8 a.m. and 1 p.m. local time for a simple port request to be eligible for activation at midnight on the same day. Any simple port LSRs received after this time will be considered received on the following business day at 8 a.m. local time.

(b) Small providers, as described in the 2009 LNP Porting Interval Order, must comply with this section by February 2, 2011.

(c) Unless directed otherwise by the Commission, any telecommunications carrier granted a waiver by the Commission of the one-business day porting interval described in paragraph (a) must complete a simple wireline-to-wireline or simple intermodal port request within four business days unless a longer period is requested by the new provider or by the customer.

(d) All telecommunications carriers required by the Commission to port telephone numbers must complete a non-simple wireline-to-wireline or non-simple intermodal port request within four business days unless a longer period is requested by the new provider or by the customer.

(e) For purposes of this section:

(1) The term “local time” means the predominant time zone of the Number Portability Administration Center (NPAC) Region in which the telephone number is being ported; and

(2) The term “intermodal ports” includes

(i) Wireline-to-wireless ports;

(ii) Wireless-to-wireline ports; and

(iii) Ports involving interconnected VoIP service.
