800 toll-free numbers are one of the most popular features of the American telephone system. Introduced in 1967, they allow callers to contact businesses and organizations without being charged for the call. 800 numbers can be used for a variety of purposes, including customer service, order processing, and technical support...
In order to use an 800 number, the caller must first dial toll-free. This prefix is designated by a 1-800, 1-888, 1-877, or 1-866 area code. Once the call is connected, the caller can then dial the number they are trying to reach.
