Poczta Polska, the Polish postal service, was founded in 1558 and postal markings were first introduced in 1764.
 The three partitions of Poland in 1772, 1793 and 1795 saw the independent nation of Poland disappear.
 The postal services in the areas occupied by Germany and Austria were absorbed into those countries' postal services.
 In 1772 the area occupied by Austria was created into the Kingdom of Galicia, a part of the Austrian Empire.
 This lasted till 1918.
 The Duchy of Warsaw was created briefly, between 1807 and 1813, by Napoleon I of France, from Polish lands ceded by the Kingdom of Prussia under the terms of the Treaties of Tilsit.
 In 1815, following Napoleons’ defeat in 1813, the Congress of Vienna, created Congress Poland out of the Duchy of Warsaw and also established the Free City of Kraków.
 Congress Poland was placed under the control of Russia and the postal service was given autonomy in 1815.
 In 1851 the postal service was put under the control of the Russian post office department regional office in St Petersburg.
 In 1855 control was restored for a while to the Congress Kingdom but following the uprising in 1863 again came under Russian control from 1866 and continued until World War I.
 In November 1918 the Second Polish Republic was created.

 Originally known as Royal Mail Canada (the operating name of the Post Office Department of the Canadian government founded in 1867), rebranding was done to the “Canada Post” name in the late 1960s, even though it had not yet been separated from the government.
 On October 16, 1981, the Canada Post Corporation Act came into effect.
 This abolished the Post Office Department and created the present day Crown corporation which provides postal service.

Afghan Post is the national post office of Afghanistan.
 It is responsible for providing postal service in Afghanistan.
 Afghanistan first established a postal service in 1870, where it received international recognition.
 On the eve of the Soviet invasion it had grown into one of the stronger regional postal services, able to send and receive letters from anywhere in the world in a timely manner.
 During the 1990s the Afghan postal service lay in near total ruin, undone by the nation's civil war.
 Sending a letter usually meant having to find someone traveling in the direction of the recipient willing to carry a note and hoping for the best.
 Since the civil war, the postal service has reinvented itself with offices in all 34 provinces, and, it is close to having offices in all 364 districts.
 As the government struggles to develop despite an excess of foreign aid, the post office has quietly managed to become one of the most efficient national institutions – and with extremely limited international assistance.
 Though street addresses are a foreign concept in Afghanistan, the postal service manages to do house deliveries.
 The Afghan postal service has turned into a promising administration.

The Army Postal Service (APS), functions as a government-operated military mail system in India.
 A primary feature of Army Postal Service systems is that normally they are subsidized to ensure that military mail posted between duty stations abroad and the home country (or vice versa) does not cost the sender any more than normal domestic mail traffic.
 In some cases, Indian military personnel in a combat zone may post letters and/or packages to the home country for free, while in others, senders located in a specific overseas area may send military mail to another military recipient, also located in the same overseas area, without charge.
 Officers are deputed primarily from the Indian Postal Service and from the Army Corps.
 Army Postal Service is the only service that enables civil service officers to work in the armed forces.
