  • NANPA Annual Report 2018
    North American Numbering Plan Administrator Annual Report 2018 1 NORTH AMERICAN NUMBERING PLAN Background In October of 2018, following a competitive bidding process, the Federal Communications Commission (FCC) awarded Somos, Inc. (Somos), the contract to perform the North American Numbering Plan Administrator (NANPA) services, effective January 1, 2019. Pursuant to this award, the system and personnel transitioned from the incumbent to Somos. The NANPA is required to publish, within the first quarter of the year, an annual report covering the performance of the prior year. Somos did not serve as the NANPA during 2018; however, the same personnel who performed the NANPA services in 2018 are now employees of Somos. Somos therefore submits the following 2018 Annual Report in the interest of providing informational continuity to the FCC and the industry. By doing so, Somos does not intend to speak for or represent the interests of the former incumbent. History The North American Numbering Plan (NANP) was developed by AT&T in 1947 to simplify and facilitate direct dialing of long-distance calls. NANP telephone numbers are ten-digit numbers consisting of a three-digit Numbering Plan Area (NPA) code, commonly called an area code, followed by a seven-digit local number. The NANP is an integrated numbering plan serving twenty North American countries that share its resources. Regulatory authorities in each participating country have plenary authority over numbering resources, but all participating countries, implicitly or explicitly, share numbering resources cooperatively. This approach has been successful for seventy years. North American Numbering Plan Administration AT&T administered shared numbering resources such as area codes until divestiture of the Bell System in 1984, when these functions were transferred to Bellcore under the Plan of Reorganization.

Adam Smith Assaults Ma Bell with His Invisible Hands: Divestiture, Deregulation, and the Need for a New Telecommunications Policyt by PAUL STEPHEN DEMPSEY* The Parable Of The Great Fish And it came to pass that God looked down upon the Great Fish and inquired, "You are a wise old fish. Tell me, what is this thing, water, in which ye swim?" And the fish thought for a moment, and replied, "I can neither taste, nor smell, nor see it. I know not what water is, Oh Lord." And many months passed. And lo, one day black clouds rolled across the sky and blot- ted out the Sun, and there came a great squall, and a tempest, and a storm which washed the Great Fish onto the land.
