Databases of the telephone numbering plan correlate a string of digits, representing access digits, area codes, city codes and exchanges, to either a specific geographic location or a special telephone service such as toll-free or premium-rated (1-900 in the NANP). For rating or routing, our numbering plan databases define the public switched telephone network.
Proprietary features designed into these databases make them the only ones of their type able to handle either North American Numbering Plan points or World Numbering Plan points, with state-of-the-art feature support such as local competition, number pooling and expanded dialing plans already designed in.
