I found a couple descriptive building number plaques that date from the interwar period when Uzhhorod was part of Czechoslovakia. The signs were written in three languages: Rusyn (Ukrainian), Czech, and Hungarian. Descriptive numbers would have been unique within the municipal part (a village, a quarter, mostly for one cadastral area) or within a whole small municipality. In some Czech and Slovak settlements these descriptive buildings numbers are still used, but concurrently with newer orientation numbers.
№п. Čp. Ö.i.sz.
(stands for “№ порядковий,” “Číslo popisné,” and “Önkormányzati irányítószám”)
