Philately as one of the most popular types of collecting continued to develop in the 20th century. Along with the "[[Scott catalogue|Scott]]", "[[Stanley Gibbons catalogue|Stanley Gibbons]]", and "[[Yvert et Tellier]]" catalogs, the "[[Zumstein catalog|Zumstein]]" (first published in Switzerland, 1909), and the [[Michel catalog|"Michel"]] (first published in Germany, 1910) catalogs began publication.

In 1934, the idea to celebrate an annual Postage Stamp Day was suggested by Hans von Rudolphi, a German philatelist.<ref>[http://www.tag-der-briefmarke.com/index.php?id=29 Biography] Hans von Rudolphi [http://www.tag-der-briefmarke.com/ «Tag der Briefmarke.org».]{{in lang|de}} {{Cite web |url=http://www.tag-der-briefmarke.com/index.php?id=29 |title=Archived|access-date=2008-04-14 |archive-url=https://web.archive.org/web/20080925100400/http://www.tag-der-briefmarke.com/index.php?id=29 |archive-date=2008-09-25}}</ref> The idea was adopted rapidly in Germany, and gained later adoption in other countries. '''Stamp Day''' is a memorial day established by the postal administration of a country and annually celebrated, which is designed to attract public attention to, popularize the use of, and expand the reach of postal correspondence, and contribute to the development of philately.<ref name="Ilyushin"/> In 1968, [[Cuba]] dedicated a postage stamp for Stamp Day with an image of G. Sciltian's  "El filatelista".<ref>{{Cite web|url=https://colnect.com/en/stamps/stamp/468764-G_Sciltian_El_filatelista-Stamp_Day-Cuba|title=G.

In 1926, the [[Fédération Internationale de Philatélie]] (FIP) was founded, where international philatelic exhibitions have been regularly organized since 1929.<ref name="Ilyushin"/> The first World Philatelic Exhibition in Prague was held between August and September 1962;<ref>''Bernhard K.'' Forum of philatelists of the globe // Soviet collector. — М: Connection publisher, 1963. — P. 42—48.</ref> in 1976, the FIP brought together national societies from 57 countries, which held over 100 exhibitions, and in 1987, over 60 countries entered the FIP.<ref name=Ilyushin />

Since the middle of the 20th century, philately has become the most widespread field of amateur collecting, which was facilitated by:<ref name="Britannica" />

Philately magazines, at this time, were published as far east as Poland, and as far west as North America. In Canada, [https://canadianstampnews.com/ ''Canadian Stamp News''] was established in 1976 as an off-shoot to [https://canadiancoinnews.com/ ''Canadian Coin News''], which was launched about a decade earlier.

Philately was largely advanced by the USSR and nations within its sphere of influence, and the United States, France, the UK, and Austria. The [[British Library Philatelic Collections]] and the postal museums in [[Stockholm]], [[Paris]], and [[Bern]] had unique national philately collections at that time, and among the famous private collections are those of the [[Royal Philatelic Collection]], F. Ferrari (Austria),<ref name="Ilyushin" /> [[Maurice Burrus|M. Burrus]] (Switzerland), [[Alfred Lichtenstein (philatelist)|A. Lichtenstein]], [[Arthur Hind (industrialist)|A. Hind]], [[John Robert Boker Jr.|J. Boker]] (U.S.), and [[Hiroyuki Kanai|H. Kanai]] ([[Japan]]).

In the mid-1970s, national philately organizations and associations existed in most countries, and 150–200 million people were involved in philately during meetings established.<ref>{{Cite book|last=Sundararaj|first=John|url=https://books.google.com/books?id=2Z9OjwEACAAJ|title=Philately: The Art of Stamp Collection|date=2015-08-15|publisher=CreateSpace Independent Publishing Platform|isbn=978-1-5170-1465-0|language=en}}</ref><ref name="auto"/>
