@Catija I can understand that. As long as you have the Zip, the City and State are redundant, but useful for error correction (in rare cases not redundant). However, having the zip on a separate line wouldn't be to
USPS postal address standards. The USPS consistently defines the, so named, "Last Line" as City, State Zip+4. The only time they define a different bottom line is the Country for international mail (a "laster" line? :-) ).
