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. All Ukraine Post Offices ("Ukrpost / Укрпошта") have post code books that may be purchased; alternatively, postal code for a given address can be found at a dedicated website. Postal codes of the territories occupied by Russian military forces (Crimean peninsula and parts of Donetsk and Luhansk oblast) remain included into Ukrainian national postal index as "postal offices temporarily out of service".
