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. Some larger subjects begin with several three-digit codes. For instance, Moscow's postal codes fall in range from 101 to 129.
Larger cities/towns have a "pochtamt" (Russian: почтамт, from German Postamt), or a Main Post Office, which is assigned the main postal code for the city. For instance Moscow's Pochtamt has a postal code of 101000. One street in a big city can have several postal codes; for instance in Saint Petersburg (with postal codes falling in the range of 190-199), Kirochnaya Street has the following postal codes: 191028, 191123, 191124, 191015, 191014, which are based on house numbers.
Post codes in Russia are six digits long. To assist in their machine reading, envelopes are printed with a nine-segment outline for each digit, which the sender fills in. However, this is not necessary and the postal code can be written by hand as in any other country. The code usually identifies the post office.
Post codes in Russia are fully compatible and not overlapping with Postal codes in Belarus.
