So, you're looking for a Biloxi MS zip code. It sounds like a simple Google search, right? You type it in, get five digits, and move on. But honestly, if you’re moving here, sending a package to a casino, or trying to figure out why your GPS is acting funky near Keesler Air Force Base, those numbers matter way more than you'd think. Biloxi isn't just one big blob on a map. It’s a skinny, stretched-out city squeezed between the Mississippi Sound and the Back Bay, and the zip codes tell the story of how the city survived Katrina and where the money is flowing now.
Most people don't realize that Biloxi basically splits into three distinct worlds. You've got the historic, salt-crusted downtown. Then there's the suburban sprawl creeping north of the bay. Finally, you have the military footprint that basically functions as its own zip-coded sovereign nation.
The Big Three: 39530, 39531, and 39532
If you are looking for the heart of the action, you’re looking for 39530. This is the "Old Biloxi" zip code. It covers the eastern tip of the peninsula. When you see photos of the Biloxi Lighthouse or the massive Beau Rivage and Hard Rock casinos, you're looking at 39530. It’s dense. It’s walkable—well, as walkable as South Mississippi gets in 90-degree humidity.

The vibe changes fast once you cross over toward the west. 39531 is the central stretch. This area is a mix of beachfront condos and older residential neighborhoods like Edgewater Park. It’s also where the shopping happens. If you’re heading to the Edgewater Mall, you’re firmly in 39531 territory.
Then there is 39532. This is the one that trips everyone up. It’s huge. It covers North Biloxi, stretching all the way up past I-10 into Woolmarket. If your address is in 39532, you probably aren't waking up to the sound of waves. You're more likely to have a backyard with pine trees and a much lower chance of needing flood insurance. It's the suburban escape.
Why the 39534 Zip Code is Different
Wait. There’s another one.
39534 is strictly for Keesler Air Force Base. If you aren't in the military or married to someone who is, you probably won't have much business here. It’s a "unique" zip code, meaning it’s assigned to a specific organization or entity. Don't try to find a civilian apartment in 39534; it’s not happening. The base is a massive part of the local economy—the "electronics center of the Air Force"—and its zip code reflects that isolation from the standard city grid.
The Real Cost of a Zip Code
In Biloxi, your zip code is basically a shorthand for your insurance premium. It’s harsh, but it’s true.
Living in 39530 or 39531 means you are south of the CSX railroad tracks. In the eyes of an insurance adjuster, that means "high risk." After Hurricane Katrina wiped the slate clean in 2005, the building codes changed. Now, if you're building a house in the 39530 Biloxi MS zip code, it better be on stilts or built like a brick fortress.
People moving from out of state often get sticker shock. They see a beautiful historic home for a "cheap" price, only to find out the annual wind and hail insurance costs as much as a used car. North Biloxi (39532) became the promised land for locals because it sits higher. It’s generally "Flood Zone X," which is the gold standard for "I won't lose my living room to a storm surge."
Breaking Down the Neighborhoods
Let's get specific.
- Downtown (39530): This is where you find the Ohr-O'Keefe Museum of Art. The houses are a mix of tiny "Shotgun" cottages and grand historic mansions. It feels like a miniature New Orleans but with more shrimp boats.
- West Biloxi (39531): Think "tourist corridor." Most of the mid-range hotels and the better-known restaurants like Mary Mahoney’s or Snapper’s are around here. It’s busy. It’s loud. It’s fun.
- Woolmarket/North Biloxi (39532): This is the future of the city's population growth. It’s where the new schools are being built. It’s technically Biloxi, but it feels like a different world compared to the casino strip.
Does it actually matter for your GPS?
Actually, yeah.
Biloxi has a weird quirk where street names repeat or change names mid-block. If you just type "Main Street" into your phone without the Biloxi MS zip code, you might end up in a different part of the coast entirely. Gulfport and Ocean Springs are right on the borders. Sometimes the mail carriers even get confused because the city boundaries are so jagged.
Also, keep an eye on the "Point Cadet" area in 39530. It’s the very tip of the peninsula. If you're staying at the Golden Nugget or Margaritaville, you're at the end of the line. The 39540 zip code is sometimes cited, but that’s generally for PO Boxes. Don't use it for a physical delivery unless you want your package sitting in a post office lobby.
Getting the Mail Right
If you're sending something to a casino guest, the zip code is vital because these places are like small cities. A casino might have thousands of rooms.
- Use the physical address (e.g., 875 Beach Blvd for Beau Rivage).
- Use 39530.
- Always include the guest's name and "Registered Guest" on the envelope.
The post office on Main Street is the primary hub for the downtown area. It’s a beautiful building, but parking is a nightmare during the lunch rush when everyone is trying to grab their mail. If you need a passport or a bulky shipping job, many locals actually drive north to the 39532 post offices where things are a bit more spread out.
The Surprising Statistics of 39532
Most people assume the 39530 zip is the wealthiest because of the casinos. Nope.

The 39532 zip code actually has some of the highest median household incomes in the area. Why? Because that’s where the doctors, lawyers, and base commanders live. They want the big yards and the safety of the I-10 corridor. It's a classic case of the "working" part of the city being by the water and the "living" part being tucked away in the woods.
What You Should Do Next
If you are planning a move or just visiting, don't just look at the city name.
Check the elevation of the specific Biloxi MS zip code you're eyeing. Use the FEMA Flood Map Service Center to see exactly where your potential front door sits. It sounds boring until you see your first tropical storm brewing in the Gulf.
Second, if you're a business owner, look at 39532 for commercial space. The traffic counts near the Promenade shopping center are some of the highest in the state.
Lastly, grab a map and drive the length of Highway 90. Start at the bridge in 39530 and drive west through 39531. You'll see the transition from old-world fishing village to modern tourist hub. It's the best way to understand why a simple zip code carries so much weight in this town. It's not just a number; it's a "where were you during the storm" marker.
Take a look at the local property tax records too. The Harrison County Tax Collector website is a goldmine. You can search by zip code to see how much people are actually paying to live on the water. It’s a reality check that every newcomer needs before they fall in love with a view.

If you're just here for a weekend at the Beau Rivage or the Hard Rock, just stick 39530 into your Uber app and enjoy the seafood. You really can't go wrong with a po-boy from Taranto's or a sunset at the Small Craft Harbor. Just make sure you're in the right part of town before you start walking. The distances in Biloxi are deceptive, and that Mississippi sun is no joke.
Plan your route, check your flood zone, and always, always double-check your zip before you hit "order" on that moving truck. It makes all the difference between a breezy coastal life and a very expensive lesson in geography.
