The "Ardatov-type" stamp is the philatelic name for the fifth design type used by EZGB for issuing Zemstvo postage stamps from 1902. According to published sources, the name was derived from Ardatov Uyezd, for whose stamp printing it was first employed. 3rd issue.
On March 1, 1903, the Zemstvo post of Poltava Uyezd (Poltava Governorate) was opened. Mail was dispatched twice a week from the uyezd center, the city of Poltava, to 17 volosts of the uyezd. For payment of private correspondence, Zemstvo postage stamps were used: ordinary letters were paid with 3-kopeck stamps, and registered letters with 6 kopecks. They are highly diverse in printing method and purpose (official, for ordinary and registered wrappers, money correspondence, etc.).
In 1908, commemorative stamps were issued for the 200th anniversary of the Battle of Poltava.
Many issues depict the uyezd coat of arms. The stamps were printed in private printing houses, and from 1905 at EZGB.
Imperforate stamps were of unofficial origin and intended for collectors. The stamps were cancelled with circular, oval, and rectangular postmarks.
