From Usenet: As some readers of this list may not know, under Equal Access, any long-distance company can carry 1-800 traffic. Which carrier gets the call is determined (at the moment) by the NNX of the number. I.E. 1-800-528-1234 (The nation-wide number for making reservations at a Best Western Motel) is carried by AT&T. While 1-800-888-1800 is carried by MCI. The carrier must have Feature Group D presence for originating calls from the originating exchange (either direct, or through an access tandem). In the future, when CCIS becomes wide-spread, a query will be made in the database [Who gets 1-800-985-1234?] and the call will be routed appropriately. To clarify: Now the carrier is determined by the NNX. In the future, the carrier will be determined by the entire 7 digits. A similar situation exists with 900 service. Each carrier can reserve NXX-s from BellCore (the people who among a zillion other tasks are in charge of handing out prefixes and area codes). They're not cheap! To get the actual number is free (there are qualifications that I don't deal with), but to get it 'turned on' in a LATA costs you money, depending on (1) How many prefixes you're getting, (2) whether it's 800 or 900 service, (3) How many Tandems/End Offices are in the LATA. It requires a discrete amount of labor for EACH office, because EACH routing table must be modified. Of the 800 possible NXX-s, 409 are currently %99 long-distance carrier can get one 800 and four 900 numbers just for the paperwork. But to get more than that, you have to show that you're 70% full now, and demonstrate a real need for the capacity. I have included the entire 800-NXX to long-distance carrier translation table. Note that not every NXX is valid in every area.
