A long-distance call is therefore known not as a "toll call" but as a trunk call. It traditionally carried a higher rate ("national rate" instead of "local rate") and requires a trunk prefix and area code be dialled before the number. A trunk call is prefixed with '0' for national calls and '00' for international calls, following the European ...

A San Diego call center would be less fortunate; even with "band 6" (the most expensive lines), its national number would be unreachable to millions as California is a populous state and intrastate calls needed a separate toll-free number. The original InWATS system was supplanted by "Advanced 800 Service" in the 1980s. [10]

This call is connected to equipment at the central office that uses automatic equipment to announce the telephone number of the line calling in. The main purpose of this system is to allow telephone company technicians ...
A zero indicated that the state or province was served by a single area code, and a one indicated multiple divisions of a state or province. Area codes were used as a universal destination routing code to the numbering plan area, and replaced the trunk routing codes that operators previously had to look up at the toll switching centers under ...
