The prefix has been introduced in July 2000 due to high demand of toll-free numbers as well as numbers beyond 800, 888, 877 prefixes became necessary. The prefixes 866 and 855 have been allocated for use in toll-free services by the North American Numbering Plan (NANP) in November 1999, however 855 was going to be activated afterwards.

866 belongs to the toll free overlay complex along with 800 and the other toll free additions such as 833, 844, 855, 877, and 888 prefixes. These toll free number ranges include the same type of toll free numbers, although having different number ranges.
