After the Polish-Soviet War it remained in Poland as a capital of a powiat within the Stanisławów Voivodship. By 1931 the number of inhabitants grew to over 41,000. The ethnic mixture was composed of Jews, Poles, Ukrainians (including Hutsuls), Germans, Armenians, and Hungarians, as well as of descendants of Valachians and other nationalities of former Austria-Hungary. With the development of infrastructure, the town became a major railroad hub, as well as the garrison city of the 49th Hutsul Rifle Regiment. In the interbellum period, every Thursday a market took place at the main square of the town. The town had a monument to Polish poet Franciszek Karpinski, a monument to Polish poet Adam Mickiewicz, and an obelisk near the town, located in a spot where in 1485 hospodar Stephen III of Moldavia paid tribute to king Kazimierz IV Jagiellon. In 1920-30s workers' strikes took place in the city, possibly organized by the Communist Party of Western Ukraine that was established in Kolomyia in 1923.
