Louisiana is the 27th most populous of the 50 United States. It has an area of 46,235 square miles (119,826 km2), and its capital is Baton Rouge. The state’s name is derived from French for “Louisiana”, a name coined by explorer René-Robert Cavelier, Sieur de La Salle in 1682.

The state is often referred to as “Louisiana”, even though it was officially named “La Louisiane” by French speakers. This pronunciation is also commonly heard in speech or news broadcasts outside of Louisiana.

Louisiana has a postal code system. It is called the Louisiana Postal Code System (LPCS), and it is used to sort and deliver mail in Louisiana. The postal code for a particular address can be found on the upper right-hand corner of the envelope or postcard.

The postal code for an address can be determined by looking at the city and state of the address, as well as the ZIP+4 code for that area. The State Library of Louisiana website provides an online tool to determine this information using your full address, including street name and number, city, state and ZIP+4 code.
