Whether you’re planning a move, shipping a package, or just curious about Louisiana’s postal codes, zip codes are key. They help pinpoint exact locations across the state, from New Orleans to Baton Rouge. Let's dive deep into everything you need to know about Louisiana zip codes, so you’re never left guessing.
What is a Zip Code?
A zip code is a system of postal codes used by the U.S. Postal Service (USPS) to streamline mail delivery. It typically consists of five digits. The first digit identifies a group of U.S. states, with Louisiana belonging to the 7xxxx range. Zip codes are crucial for identifying areas within cities, towns, and rural regions.
How Many Zip Codes Are in Louisiana?
As of now, Louisiana has over 500 zip codes spread across its parishes and cities. Each one serves a unique geographic region, ensuring mail and packages reach the right places without delay.
Major Cities and Their Zip Codes

Louisiana’s Rural Zip Codes
Louisiana is not just cities—it’s also home to vast rural landscapes, bayous, and small towns. Rural areas often cover larger land spaces with fewer residents, but zip codes remain just as crucial. Here are a few rural zip codes:

In these areas, zip codes help differentiate between sprawling farms and small communities.
Zip Code Format in Louisiana
Every Louisiana zip code follows the standard five-digit format, but you might sometimes see them extended with four extra numbers (e.g., 70112-1234). This is called the “ZIP+4” code, which helps USPS further pinpoint a specific location, like an apartment within a building or a specific office in a complex.
The first three digits of a Louisiana zip code (701, 708, etc.) help identify regions, while the last two digits get down to a more local level. This structure ensures that no matter where you are—whether in a big city or rural town—your mail finds you.
How to Find a Louisiana Zip Code
Finding a zip code in Louisiana is easier than ever. Here are a few simple methods:
- USPS Website: The USPS website offers a free zip code lookup tool where you can enter a city, address, or even a company name to find the correct zip code.
- Google Maps: Another quick way to locate a zip code is by typing the address into Google Maps. The zip code will show up right below the address in most cases.
