The history of the postage stamps of the Far Eastern Republic covers the organization of postal communications in the Far Eastern Republic (FER), a buffer state formation in the territory between Lake Baikal and the Pacific Ocean, beginning on April 6, 1920, when the republic was proclaimed by the Constituent Congress of the Working People of the Baikal Region. From October 1920, Chita became the main city of the republic. In fact, there were two centers—Chita and Vladivostok. In these same centers, postage stamps were issued for the republic’s postal needs. On November 15, 1922, the FER became part of the RSFSR; however, issues of its own stamps in the territory continued even after reunification, up to 1923.
In November 1920, in Vladivostok, stamps for Primorskaya Oblast were issued with a lithographed overprint in black ink of the abbreviation “FER” on stamps of the Russian Empire’s 17th, 20th, 21st, and 22nd issues, on Russia’s savings stamps, and on stamps of the Omsk government. On some stamps, in addition to the abbreviation, a new value figure was overprinted between two letters “k”.
