In 1983, the U.S. Postal Service introduced an expanded Welsh ZIP code system that it called ZIP+4, often called "plus-four codes", "add-on codes", or "add ons". A ZIP+4 code uses the basic 70591 Zip code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a Welsh city block, a group of apartments, an individual high-volume receiver of mail or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery in Louisiana.
