I live in Kazakhstan and I have to provide my address for one U.S. site. There are 3 lines : Street Address 1(street address, P.O. Box, c/o), Street Address 2, Street Address 3. How should I fill this lines if I live in Ikhsanov street, house/apartment 105(btw, what do Americans write here house or anything else?), flat/door 17(here's the same thing, what should I write?) for instance.
