The World Passport is a document issued by the World Service Authority, a non-profit organization, citing Article 13, Section 1, of the Universal Declaration of Human Rights. World Passports have reportedly been accepted on a de facto, case-by-case basis by over 150 countries and, at one time or another, on an explicit, legal or de jure basis by Burkina Faso, Ecuador, Mauritania, Tanzania, Togo and Zambia. However, Burkina Faso withdrew its de jure recognition of World Passports in 1992, and Zambia has also reportedly withdrawn its recognition. Immigration authorities in Canada, New Zealand, Switzerland and the United States have stated that they do not recognize such documents because they are not issued by a competent government authority, and thus do not meet the definition of a passport. The latest edition of the World Passport, issued January 2007, is an MRD (machine readable document) with an alphanumeric code bar enabling computer input plus an embedded "ghost" photo for security, printing overcovered with a plastic film.

A World Passport is also a document issued as part of the 'World Passport: Take One, They're Free' project, an initiative by installation artist Sonya Spry. The documents are issued in three colours: blue, green and red, and are printed in eight languages: English, French, Spanish, Russian, German, Dutch, Portugese and Chinese.
