Telephone Collectors International was incorporated under the laws of the state of Kansas on May 13, 1986. The goal of the organization is "to educate the public, as well as the members of the Corporation, regarding the history of telephony, the value of old telephones and related items, their collectability and preservation; to research telephone history and publish and provide literature thereon; to promote the public exhibition of old telephones and related items; and to promote common courtesies and guidelines for use by the public." Telephone Collectors International is recognized by the Internal Revenue Service as a 501(c)(3) organization, to which U.S. tax deductible contributions can be made.
