Russia Postal Codes and Addressing Guide
How Russian postal indexes and addresses work, how to write them correctly, and how a UPCS RU code can pinpoint an exact delivery spot.
Updated 14 October 2026 · 3 min read
Russia has a nationwide postal system run by the national operator, Russian Post (Pochta Rossii), and every settlement with a post office is covered by a six-digit postal index. Addresses are written in Russian, usually in Cyrillic, and follow a structured order of region, city, street, house and flat.
How the Russian postal system works
The postal index (почтовый индекс) is a six-digit number. It identifies a specific post office or delivery unit rather than a single building, so many streets and sometimes whole villages share one index. The first digits narrow down the region and the main sorting centre, while the final digits point to the local office. The index is printed with the address on letters, parcels and online forms, and it is commonly a required field in Russian checkouts.
Because the country is very large and includes both dense cities and remote settlements, the quality of address data varies. A central apartment block in a big city is easy to describe; a house in a small village may have no street name and be located only by village and house number.
How addresses are written
A Russian address is usually written from the general to the specific, or with the index placed first. Typical components are the index, country, region (oblast, krai or republic), district, city or village, street, house number, building (korpus) and apartment. You can read the full component order on the Russian address format page.
For international mail the address is often transliterated into Latin letters, with the country name written in the language of the sending country or in Latin script. Mixing Cyrillic and Latin in one address is a frequent source of confusion for sorting staff.
How UPCS codes work in Russia
UPCS codes for Russia start with the prefix RU and follow the pattern RU-XXXX-XXXX, where each X is a letter or digit. A code represents a 3 m by 3 m grid cell chosen on the map, so it points to an exact spot such as a gate, an entrance or a courtyard door.
A UPCS code is not an official postal index. It is not issued by Russian Post or any authority and does not replace the six-digit index or the street address. It is meant to accompany the normal address, helping a courier or visitor find the precise place once they are in the right neighbourhood.
