History of SMS/800

1967

Toll Free numbers were introduced by AT&T as what they called Inward Wide Area Telecommunications Services (INWATS). Customers could receive calls originating within a relatively wide geographic area and pay for them on a "bulk" basis instead of being charged for individual calls.

1981

The computer revolution led to the implementation of a first-generation system of centralized databases for processing Toll Free number calls according to the specific instructions in Customer Records.

1984

With the Bell System divestiture, Toll Free service was required to be opened to competition. As a result, an 800 service network had to be developed that would make Toll Free service offerings possible for any telecommunications company.

1991

The FCC issued an order to make Toll Free number fully portable by March 4, 1993. In 1992, the FCC extended the deadline to May 1, 1993.

Number Portability means that Toll Free numbers are not associated with a particular Responsible Organization (Resp Org) or carrier. Toll Free Subscribers can switch to another Resp Org or carrier without changing their Toll Free number(s), and they can choose separate carriers for specific kinds of traffic. Before number portability, Toll Free subscribers were locked into their carriers. They could not change those carriers without changing their Toll Free numbers.
