In 1983, the U.S. Postal Service introduced an expanded Huntington Beach 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 92605, 92615, 92646, 92647, 92648, 92649 Zip code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a Huntington Beach 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 California.
The US ZIP Code basic format consists of five decimal numerical digits assigned to the Huntington Beach City. An extended ZIP+4 code, introduced in the 1980s, includes the five digits of the Huntington Beach ZIP code, a hyphen, and four more digits that determine a more specific location within a given ZIP code in Huntington Beach, California.
