I located how to address mail in the Russian Federation format: Reverse

>the information order as we address it in the U.S. In other words,top
>line is the addressee's name, then the postal code is first, then
>town/city (second line), then the street, box, etc. address is the last
line.

When I have sent mail to Russia, I have addressed the envelope in Russian
with the Cyrillic font, rather than in English with the Latin font. I
wonder if I really have to do this, whether it improves the reliability of
the letter reaching its destination.
