Does a PO box use the same code as the building?

Not necessarily. Use the code published for the physical premises. For example, Heureka’s visitor address uses 01300, while its separate PO box uses 01301. Never transfer a PO-box code to a street address.

Should I translate Finnish or Swedish street names?

No. Keep the source-supported street name and spelling. Finnish and Swedish names can be official alternatives; they are not transliterations. Use one consistent published address.
