NUMBERING RESOURCES OPTIMIZATION (NRO) WORKING GROUP OF THE NORTH AMERICAN NUMBERING COUNCIL (NANC)

The following links will take you to the ATIS.ORG site who is graciously hosting the various NRO documents for the NANC (North American Numbering Council).

The Numbering Resources Optimization (NRO) Working Group of the NANC will assess and recommend strategies that ensure equitable availability of number resources to all end users and service providers while optimizing the use of numbering resources. Such strategies should be technically feasible, practical and should minimize the cost to both end users and service providers.
