what does the zip in zip code stand for
ZIP Code ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan,[1] was chosen to suggest that the mail travels more efficiently, and therefore more quickly (zipping along), when senders use the code in the postal address. The basic format consists of five digits. An extended 'ZIP+4' code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code.
Area codes 614 and 380 Area code 614 and 380 are the area codes in the North American Numbering Plan for Columbus, Ohio and most of its close suburbs. Area code 614 is one of the original area codes assigned for Ohio in 1947, while area code 380 is an overlay code covering the same territory.
