Postal codes in Russia

Russian Post has a system of postal codes (Russian: почтовый индекс, pochtovyy indeks) based on the federal subject a place is located in.

Each postal code consists of six digits with first three referring to the federal subject or the administrative division with special status.

For instance, Moscow's postal codes fall in the range 101–129.

To assist in their machine reading, envelopes are printed with a nine-segment outline for each digit, which the sender fills in.

In 2014, some areas of Ukraine under Russian administration were assigned Russian postal codes in the range 295–299, adding an initial 2 to the existing Ukrainian five-digit codes.
