Main Page | See live article | Alphabetical index A toll free telephone number is one in which the calling party is usually not charged for the call. Generally, the called party pays all of the charges for the call. Toll-free numbers in America (known as WATS lines), and also originally Australia, are sometimes called "800 numbers" after the original area code which was used to dial them. (There are additional area codes in the United States including 888 and 877 which are also used for toll-free numbers.) In Australia now, the prefix is "1800" for toll free (or free call) numbers.
