>US addresses exhibit neither increasing nor decreasing specificity. Apartment numbers are usually written in the middle, like "30 Tristan Way, Apt. 107, Gwyneth VA 27384". This never seemed strange to me until I saw it being done more sensibly elsewhere. Best to think of it as an onion. On the outer layers (beginning and end) automated and semi-automated sorting can be applied most easily (the ZIP code was designed for automated sorting and routing). Apartment and suite numbers in the middle are handled (usually) manually by carriers already at or near the service address.
