How does cmte accomplish its purpose?*The purpose of the NANC is to advise the Federal Communications Commission on numbering matters and to make recommendations, reached through consensus, that foster efficient and impartial administration of the North American Numbering Plan (NANP). To accomplish its purpose, the NANC facilitates its work through Working Groups, which report their activities and recommendations to the full membership of the NANC. The NANC met seven times during FY20 to discuss and vote on the recommendations from its Working Groups and provided the following reports to the Commission:

(1) Reassigned Numbers Database (RND) Technical Requirements Document (TRD) and Funding Recommendations. The Commission adopted rules in December 2018 that established a single, comprehensive database containing potentially reassigned numbers. At that time, the Commission directed the NANC to present it with a TRD containing recommendations on technical and operating standards for the Reassigned Numbers Database Administrator. In addition, the Commission directed the NANC to develop and submit recommendations to the Commission on issues and considerations related to: (a) the RNDA collecting fees from database users, including how to structure such fees and the amount of such fees; and (b) the billing and collection from telecommunications service providers of RND creation costs, and the subsequent return of such amounts to service providers, to be administered by the Billing and Collection Agent, and interaction and coordination necessary and advisable between the RNDA and the Billing and Collection Agent in performing these roles. The NANC approved its recommended TRD at its January 13, 2020 meeting and submitted it to the Commission on the same day. On January 24, 2020, the Wireline Competition Bureau and Consumer and Government Affairs Bureau (Bureaus) released a Public Notice seeking comment on the TRD. A month after approving and submitting the RND TRD, the NANC approved and submitted to the Commission its RND fee/funding recommendations on February 13, 2020. On February 26, 2020, the Bureaus released a Public Notice seeking comment on the fee/funding recommendations. The Commission plans to award by the end of calendar year 2020 a contract consolidating the North American Numbering Plan Administrator and Pooling Administrator, combined with theRNDA functions;

(2) Interoperable Video Calling (IVC) Working Group (WG) Report. On December 16, 2019, the IVC WG was directed via a letter from the Wireline Competition Bureau (Bureau) to address: (a) whether it would be preferable to use one or more existing numbering databases or establish a new IVC database; (b) performance and security measures that would need to be established for IVC to work effectively using any endpoint; and (c) how the database(s) should be funded and which parties should bear the costs. The IVC WG was also asked to evaluate the technical and operational feasibility of interoperating with Telecommunications Relay Services (TRS) to ensure that persons with disabilities can connect directly to Public Safety Answering Point telecommunicators. On July 28, 2020, the NANC approved the IVC WG report, which provided recommendations for using a distributed database approach to allow video calls to be placed or received with ten-digit telephone numbers on an interoperable basis. The report also examined the ability of TRS users to interact with IVC calls with other TRS users, non-TRS users, and to and from 9-1-1. The final approved IVC WG report was submitted to the Commission on July 29, 2020;

(3 Nationwide Number Portability Working Group (NNP WG) Report. In a separate letter on December 16, 2019, the NANC’s NNP WG was tasked by the Bureau with further examination of the Internet Protocol Local Routing Number (IPLRN) solution. Specifically, the NNP WG was tasked with: (a) analyzing the likely effects of IPLRN; (b) recommending how to move forward with IPLRN (including what steps would need to be taken and how long the NNP WG estimates each step would take); (c) whether the IPLRN solution should be modified in light of any changes since the previous report; and (d) how to address the concerns and objections raised in the minority report issued with the previous report. On July 28, 2020, the NANC voted to approve the NNP WG report, which developed more specific recommendations regarding: (a) the IPLRN solution for NNP, including analyzing the potential effects of the proposed IPLRN solution; (b) providing recommended steps for moving forward with IPLRN; (c) considering whether the solution should be modified in light of changes since the NNP WG previously examined the issue; and (d) addressing issues raised in a minority report of the previous NNP WG report. The NANC submitted the NNP WG report to the Commission the following day, along with a minority report submitted by a member of NNP WG and the NANC;

(4) Evaluation of the 833 Toll Free Auction. In another December 16, 2019 letter from the Bureau, the Toll Free Assignment Modernization (TFAM) WG was charged with evaluating the 833 Auction from the perspective of participants in 833 Auction and those that may participate in future auctions. Specifically, the December directive required the TFAM WG to evaluate the 833 Auction design, education and outreach efforts, application process, upfront payment mechanism, and provide recommendations for future auctions. To accomplish its work, the TFAM WG solicited feedback from 833 Auction participants and examined public comments received from the Commission Public Notice released in March 2020. On July 14, 2020, the NANC submitted the 833 Auction report, which included recommendations for improvements to bidder’s experiences in applying to participate in the Auction and in bidding;

(5) 2019 Billing and Collection (B&C) Agent Evaluation. As part of its responsibilities under 47 CFR §52.11(h) to monitor the performance of the B&C Agent on at least an annual basis, on July 14, 2020, the NANC approved and submitted an evaluation conducted by its Numbering Administration Oversight Working Group that concluded that the Billing and Collection Agent successfully met all of its performance requirements; and

(6) Call Authentication Trust Anchor (CATA) Working Group Report. As required by the Pallone-Thone Telephone Robocall Abuse Criminal Enforcement and Deterrence (TRACED) Act, on February 27, 2020, the Commission charged the CATA WG with recommending a set of best practices to address: (a) which aspects of a subscriber’s identity should or must be collected by a provider to enable it to accurately verify the identity of a caller; (b) what guidelines or standards should providers use when assigning the three attestation levels— A (or “full” attestation), B (“partial”), and C (“gateway”)—of the SHAKEN/STIR framework; (c) how best practices should vary depending on the type of subscriber (e.g., large enterprises vs. individuals vs. small businesses); (d) when providers should consider using third-party vetting services and how they should make the best use of them; (e) whether there should be unique industry-wide best practices for knowing the identity of subscribers located abroad and, if so, best practices that the Bureau could recommend for identifying such subscribers; and (f) whether there are any other best practices voice providers can implement “to take steps to ensure the calling party is accurately identified.” On September 24, 2020, the NANC approved and submitted to the Commission the CATA report, which, as directed, recommended best practices for vetting the identity of subscribers; validating the right to use a telephone number; authenticating calls with A-, B- and C-level attestations; use of third party validation services; validating international calls; and ongoing robocall mitigation practices. On October 1, 2020, the Bureau released a Public Notice seeking comments on the CATA WG Report.
How is membership balanced?*The NANC achieved a well-balanced membership by soliciting, through public notice, and including representatives from every sector of the telecommunications industry, as well as representatives of state regulators, consumer and community organizations and other stakeholders and interested parties with relevant experience. Industry representatives come from competitive local exchange carriers, incumbent local exchange carriers, wireless carriers, cable service providers, toll free service providers, interconnected voice over internet service providers and IP-enabled service providers, telecommunications equipment manufacturers, and industry trade and standards associations.
How frequent & relevant are cmte mtgs?*We expect that there will be no more than four council meetings per year. In addition, interim conference call meetings are held as necessary. Meetings address current number administration issues that have competitive significance to the telecommunications industry.
Why advice can't be obtained elsewhere?*The Commission needs consensus advice from the industry on number administration issues so that it can make timely, informed decisions affecting competition in the telecommunications industry. The NANC is important to this process in that it facilitates industry consensus on complex numbering matters and provides initial dispute resolution. By developing a reliable technical record on difficult numbering issues, the Council can greatly expedite the Commission's policy and rulemaking functions.
Why close or partially close meetings?The portion of a meeting which involves the disclosure of trade secrets and commercial or financial information obtained from a person that is privileged or confidential, is subject to the Government in the Sunshine Act (GISA), which permits closure of meetings. Otherwise, all NANC meetings are open to the public. See GISA Section 552b(c)(4).
Recommendation RemarksThe NANC is supported by five major working groups. Their work is critical to the NANC recommendation process, which assists the Commission with its goals as outlined in the Administration of the North American Numbering Plan, Report and Order, CC Docket 92-237 and Local Number Portability, CC Docket 95-116, Second Report and Order. The working groups include the following: Numbering Administration Oversight Working Group; Call Authentication Trust Anchor Working Group; Toll Free Assignment Modernization Working Group; National Number Portability Working Group; and the Interoperable Video Calling Working Group. The NANC charter was renewed on September 16, 2019. Letters were mailed to the appropriate congressional officials, informing them of the committee's new charter termination date of September 16, 2021.

Agency Feedback Comment*The agency provides feedback through the Designated Federal Officer (DFO) or through correspondence between the Commission and the NANC.Narrative Description*The Federal Communications Commission (Commission) is responsible to Congress and the American people for ensuring that an orderly framework exists within which communications products and services can be quickly and reasonably provided to consumers and businesses. In support of this mission, one of the Commission's goals is to support the Nation's economy by ensuring that there is a comprehensive and sound competitive framework for communications services. The North American Numbering Plan (NANP) is the basic numbering scheme that permits interoperable telecommunications service within the United States, Canada, Bermuda, and most of the Caribbean. The NANP provides a framework for assigning the telephone numbers upon which those services depend for permitting calls throughout the U.S. and international calls among member countries to be completed without the need to dial international access codes and international country codes. These numbers are a public resource, and are not the property of the carriers or their subscribers. Access to numbering resources is critical to entities desiring to participate in the telecommunications industry. An adequate source of telephone numbers, available through a uniform numbering plan, is essential to provide consumers with efficient access to new telecommunications services and technologies and to support continued growth of an economy increasingly dependent upon those services and technologies. Telephone numbers are the means by which businesses and consumers gain access to, and reap the benefits of, the public switched telephone network. These benefits cannot be fully realized, however, unless numbering resources of the NANP are administered in a fair and efficient manner. The purpose of the North American Numbering Council (NANC) is to advise the Commission and to make recommendations, reached through consensus, that foster efficient and impartial NANP administration. The NANC advises the Commission on numbering policy and technical issues, initially resolves disputes as directed by the Commission, and provides guidance to the North American Numbering Plan Administrator (NANPA), the Local Number Portability Administrator (LNPA), and the Pooling Administrator (PA), as directed by the Commission. In carrying out its responsibilities, the Council assures that NANP administration supports the following policy objectives: (1) that the NANP facilitates entry into the communications marketplace by making numbering resources available on an efficient, timely basis to communications service providers; (2) that the NANP does not unduly favor or disfavor any particular industry segment or group of consumers; (3) that the NANP does not unduly favor or disfavor one technology over another; (4) that the NANP gives consumers easy access to the public switched telephone network; and (5) that the NANP ensures that the interests of all NANP member countries are addressed fairly and efficiently, fostering continued integration of the NANP across NANP member countries.
