A pillar box is a type of free-standing post box. They are found in the United Kingdom and British overseas territories, and, less commonly, in many members of the Commonwealth of Nations such as Cyprus, India, Gibraltar, Hong Kong, Malta, New Zealand and Sri Lanka, as well as in the Republic of Ireland. Pillar boxes were provided in territories administered by the United Kingdom, such as Mandatory Palestine, and territories with agency postal services provided by the British Post Office such as Bahrain, Dubai, Kuwait and Morocco. The United Kingdom also exported pillar boxes to countries that ran their own postal services, such as Argentina, Portugal and Uruguay.
