Phone numbers with the 800 area code prefix are non-geographic numbers. This means they are not tied to a specific metropolitan area, region, or state in the traditional sense. Instead, 800 numbers serve as toll-free numbers within the North American Numbering Plan (NANP), encompassing the United States and Canada. While toll-free numbers can be physically located anywhere in the world by the receiving party, some specific 800-NXX prefixes are reserved for individual NANP countries or areas, including:
The North American Numbering Plan designates multiple area codes for toll-free telephone numbers that work together to serve the same function. In addition to 800, these include prefixes such as 833, 844, 855, 866, 877, and 888. The 800 area code was the first automated toll-free telephone number, introduced as Inbound Wide Area Telephone Service (InWATS) in 1966 for U.S. intrastate calls and 1967 for interstate calls. After operating for over thirty years, the 7.8 million possible numbers within the 800 prefix began to deplete, leading to the introduction of these additional toll-free area codes to meet demand.
Area code 800 is a Easily Recognizable Code which was placed in service on January 1, 1947.
