Iowa Zip Code - Louisiana
The US ZIP Code basic format consists of five decimal numerical digits assigned to the Iowa City. An extended ZIP+4 code, introduced in the 1980s, includes the five digits of the Iowa ZIP code, a hyphen, and four more digits that determine a more specific location within a given ZIP code in Iowa, Louisiana.

If you want to send a mail to Iowa City, you should use the 70647 Zip Code.
In 1983, the U.S. Postal Service introduced an expanded Iowa 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 70647 Zip code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a Iowa 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.
