The first congress was held in Bern, Switzerland in 1874, and was attended by delegates from 22 countries, most of them European. The meetings are normally held every four years, although they were cancelled during the two World Wars.{{Cite encyclopedia |url=http://www.encyclopedia.com/doc/1G2-2586700057.html |title=The Universal Postal Union (UPU) |encyclopedia=Worldmark Encyclopedia of Nations |year=2007 |publisher=Encyclopedia |access-date=2010-03-25 }} Extraordinary Meetings can also be called outside the four-year cycle.

Delegates are usually presented with special albums of stamps by the other participating countries, to cover the period since the previous congress.

The service was difficult to introduce as in several countries the carriage of parcels was a monopoly of the railway companies, and Egypt, Great Britain, India, Canada and Italy all initially claimed that there was no parcel service in their country.
