Official Numbering Systems
In general, governments have not tried to number their own stamps. The People's Republic of China is a notable exception, having inscribed most of its stamps with a unique numbering system since 1949.
In 2002, as part of efforts to control allegedly illegal stamps, the Universal Postal Union introduced the WADP Numbering System (WNS) for new issues by UPU members.

Famous quotes containing the words official, numbering and/or systems:
“All official institutions of language are repeating machines: school, sports, advertising, popular songs, news, all continually repeat the same structure, the same meaning, often the same words: the stereotype is a political fact, the major figure of ideology.”
—Roland Barthes (1915–1980)
“The task he undertakes
Is numbering sands and drinking oceans dry.”
—William Shakespeare (1564–1616)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
