zip code









































a zip code is a postal code used by the united states postal service (usps) in a system it introduced in 1963. the term "zip" is an acronym for zone improvement plan; it was chosen to suggest that the mail travels more efficiently and quickly (zipping along) when senders use the code in the postal address. the basic format consists of five digits. an extended zip+4 code was introduced in 1983 which includes the five digits of the zip code, followed by a hyphen and four additional digits that reference a more specific location.
