About us



The goal of the Country Code 1 ENUM Limited Liability Company is to build the public infrastructure that will promote the development of ENUM technology in a single, carrier-class manner within the countries of the North American Numbering Plan (NANP). The countries of the NANP include the United States, Canada and some Caribbean nations.

ENUM is a technology that allows users to combine the resources of the Internet with traditional telephony, uniting these two diverse worlds of communications and enabling a whole new range of communication applications.  The ENUM system effectively enables individuals, businesses and other organizations to maximize the use of both the public Internet and the Public Switched Telephone Network (PSTN) by associating telephone numbers with Internet domain names.   As a result, phone numbers can be used to send traditional telephony services like voice calls or faxes which can be converted to digital packets for delivery to a variety of devices.

A common ENUM system becomes increasingly essential as applications like voice over IP (VoIP) become more widely adopted.  The ENUM system bridges the technology gap between the public Internet and the Public Switched Telephone Network so that VoIP users of different service providers can communicate more simply with each other.

We are seeking to build a commercial implementation consistent with the relevant open standards of the Internet Engineering Task Force (IETF) and the International Telecommunication Union (ITU) upon which ENUM is based.  The ENUM LLC will help to implement a single, public ENUM system for those nations within the NANP that choose to participate.  It is intended that the North American implementation of ENUM will adhere to national and industry privacy requirements.  The ENUM LLC's first task will involve selection of a vendor to take the initial steps towards creation of an infrastructure that would enable the countries within the NANP to establish their own national ENUM implementations. The company will also be responsible for selecting a vendor to develop the national infrastructure for the United States.

Country Code 1 ENUM LLC members include AT&T, Sprint-Nextel, and Verizon.
