Postal codes in Ukraine

Ukraine uses five-digit numeric postal codes that are written immediately to the right of the city or settlement name.

The codes are allocated to all settlements with a population of more than 500 irrespective of a post office presence; habitations with smaller population share a postal code of the closest code-marked settlement.

First two digits of Ukrainian postal code can change from 01 to 99 ("00" combination is not used at the first two positions) indicating national-level administrative units of state governance: Furthermore, one pair of first two postal code digits ("50") is assigned to the city of Kryvyi Rih in Dnipropetrovsk Oblast as an exemption.

The third digit of Ukrainian postal code indicates lower level of administrative units: raions and towns of oblast-level subordination.

For central post offices of raions and of oblast-level subordination towns, the fourth and fifth digits are "00"; For indication of post offices in oblasts' capital cities, capital of the Autonomous Republic of Crimea, as well as in Kyiv and Sevastopol, postal code digits from third to fifth are used; In case of the oblast's central post office (always located in the oblast's capital city), a postal code with "000" at positions 3-5 is used; For indication of inter-raion communication centers, regional centers of mail collection and processing, railway post offices and other special post offices which are not associated with specific territory, digits "999" are used at positions 3-5 of postal code.
