> Also how do you include the code? Address line 2? 3? Memo? I don't always see these. Technically as far as USPS is concerned, there are only 3 lines in an address: name, address, and city/state/zip. Address line 2/3 are non-standard and are disregarded, and you may put whatever delivery instructions in there you want. If you have an address like "Room 321" that should go as part of Address Line 1. However, mail is delivered by human beings and generally speaking you can get a surprising amount of mail delivered with non-standard addresses. It used to be quite common to give addresses in the form of "Red House on Easy Street at the top of the hill" and this will still usually make it through.
