(Redirected from Universal mail system)
The 'Universal Postal Union' ('UPU',
French: 'Union postale universelle') is an
international organization that coordinates postal policies between member nations, and hence the world-wide
postal system. Each member country agrees to the same set of terms for conducting international postal duties. Universal Postal Union's headquarters are located in
Berne.
Prior to the establishment of the UPU, a country had to conclude a separate postal treaty with each other country that it wished to carry international mail to or from. The
United States called for an international postal congress, which was held in
1863. This led
Heinrich von Stephan,
German Minister for Posts, to found the Universal Postal Union, the second oldest international organization (after the
ITU). It was created in
1874, under the name "'General Postal Union'", as a result of the
Treaty of Berne signed on
9 October 1874. In 1878, the name was changed to "Universal Postal Union".
The UPU established that (1) there should be a more or less uniform flat rate to mail a letter anywhere in the world; (2) postal authorities should give equal treatment to foreign and domestic mail; and (3) each country should retain all monies it collected for international postage.
One of the most important results of the UPU treaty was that it ceased to be necessary, as it often had been previously, to affix the
stamps of any country through which one's letter or package would pass in transit; the UPU provides that stamps of member nations are accepted for the whole international route.
After the foundation of the
United Nations, the UPU became its specialized agency.
In 1969 the UPU introduced a new system of payment by which fees were payable between countries according to the difference in the total weight of mail between the respective countries. These fees were called terminal dues. As this affected the cost of the delivery of periodicals, the UPU devised a new "threshold" system, which was implemented in 1991.
The system sets separate letter and periodical rates for countries which receive at least 150 tonnes of mail annually. For countries with less mail, the original flat rate has been maintained. The United States has negotiated a separate terminal dues formula with thirteen
European countries that includes a rate per piece plus a rate per kilogram, and has a similar arrangement with
Canada.
The UPU also operates the system of
International Reply Coupons and addresses concerns with
ETOEs.
Philatelic activities: the Universal Postal Union, in conjunction with the World Association for the Development of Philately (WADP), has developed the WADP Numbering System (WNS), launched on 1 January 2002. The web site (www.wnsstamps.ch/en/) has entries for some 160 countries and emitting postal entities, with over 25,000 registered stamps since 2002. Many of them have images, which generally remain copyrighted by the issuing country, but which the UPU and WADP permit to be downloaded.
Member countries
The
United Nations member states may all become member countries of the UPU. The 192 United Nations member states are all UPU member countries except
Andorra,
Marshall Islands, the
Federated States of Micronesia and
Palau whose situation with regard to the UPU has not yet been settled. A non-member state of the United Nations may also become a UPU member if two-thirds of the UPU member countries approve its request.
Vatican City is a UPU member country and a non-member state observer of the United Nations (as the
Holy See).
The UPU has 191 member countries since
Timor-Leste joined on
28 November 2003 and
Montenegro on
26 July 2006, including the Dutch territories of the
Netherlands Antilles and
Aruba as a single UPU member, and the
British overseas territories, which are not independent states.
The
Republic of China joined the UPU on
1 March 1914. After the
People's Republic of China was founded, the Republic of China continued to represent China in the UPU, until the UPU decided on
13 April 1972 to recognize the People's Republic of China as the only legitimate Chinese representative. This results in
International Reply Coupons not being available for Taiwan. Mail addressed to
Taiwan will still be delivered there, albeit routed through a third country.
Various other non-recognized countries such as
Somaliland,
Sealand and the
Turkish Republic of Northern Cyprus need to have their mail routed through third countries as the UPU will not allow direct international deliveries (Sealand's mail goes via the
UK, TRNC's mail via
Turkey, and Somaliland's mail via
Ethiopia). Other entities without direct UPU representation are the
Palestinian Authority and the
Sahrawi Republic /
Western Sahara.
The members are listed below by alphabetical order in their
ISO 3166 English names, with the date of entering the UPU (multiple entry dates for some countries). Territories covered by a sovereign member country are included under that country.
