The North American Numbering Plan

The network−numbering plan was designed to enable a quick and discreet connection to any telephone in the country. The North American Numbering Plan, as it is called, works on a series of 10 numbers. As progress occurs, the use of Local Number Portability (LNP) and Intelligent Networks (IN) enables the competitors to break in and offer new services to the consumer. Note that there have been some changes in this numbering plan. When it originally was formulated, the telephone numbers were divided into three sets of sequences. The area codes were set to designate high−volume usage and enabled some number recognition tied to a state boundary. With the convergence in full swing, the numbering plan became a bottleneck. Now with the use of LNP, the numbering plan will completely become obsolete as we know it. No longer will we recognize the number by an area code and correlate it to a specific geographic area. LNP will make the number a fully portable entity. Moreover, 10−digit dialing in the age of convergence becomes the norm because of the multitude of area codes that will reside in a state.
