...a lot of "small"city post numbers You can find around, especially on oicture post card that come as souvenirs on tourist destination/s, but to find small number (not ending with 000) and "important" city, that will be "hards task"!
I have one sample of posy card, with post office number 38220 .... cancel over stamp under name Srbija I Crna Gora, short lived Yugoslavia period, and what is most important, it is city name of Kosovska Mitrovica!
