A zip code, short for “Zone Improvement Plan” code, is a numerical code used in postal addresses to identify specific geographic regions for efficient mail delivery.
Introduced by the United States Postal Service in 1963, a zip code typically consists of five digits, though an optional additional four digits may provide more precise location information.
Zip codes help postal workers sort and route mail accurately, speeding up delivery and ensuring correspondence reaches its intended destination in a timely manner.
