In the US, someone I know who had a Post Office box liked writing simply `box-number zip-code` as their address.
It worked. Eg, if you wrote on an envelope:
1034
21240
It would get there! You might want to add a "Box" before the "1034" to be safe -- and to disambiguate between a house number, as in OP? (I'm not sure just a house number would ever work in the USA?)
But it looks cooler with just two numbers. Especially it did 20 years ago when my friend did it. Very futuristic cyberpunk. Maybe a square glyph for "box" would be good.
