You're probably looking for a specific number. It's 47112. That is the primary zip code for Corydon, Indiana. But if you think a five-digit string is the whole story of this place, you're missing the point of why people move here, visit here, or run businesses in the first state capital.
Corydon isn't just a dot on a map. It’s a hub. It sits in Harrison County, tucked away in the southern tip of the state, just across the river from Louisville, Kentucky. When people search for the zip code for Corydon, they're usually trying to figure out if a property is actually in town or out in the sticks of Laconia or New Salisbury.
Why 47112 Covers More Than You Think
The 47112 zip code is surprisingly expansive. It doesn't just stop at the town limits. It stretches out into the rolling hills and limestone-rich soil that defines the Ohio River Valley.
Honestly, it’s a bit of a logistical headache for newcomers. You might have a Corydon mailing address but live ten miles from the historic square. That’s just how rural Indiana mail routes work. The post office on Business Boulevard handles the bulk of it. If you're sending a package to someone living near the Harrison-Crawford State Forest, you're still using 47112.

Think about the geography for a second. The area is pockmarked with sinkholes and caves. It’s karst topography. This matters because the infrastructure—pipes, cables, and even the roads that mail carriers drive—has to navigate a Swiss-cheese landscape. When you write 47112 on an envelope, it’s traveling over some of the most complex geological terrain in the Midwest.

Most of the time, 47112 gets the job done. If you're a business owner on Chestnut Street or Federal Drive, you’ll want that +4 extension. It speeds up the sorting process at the Louisville Regional Processing and Distribution Center. That's where your mail goes first anyway. It doesn't just stay in Corydon. It goes to Kentucky, gets sorted, and comes back. Kinda weird, right? But that’s the USPS for you.
The First State Capital Factor
Corydon is old. Like, "older than the state of Indiana" old. It was the capital from 1816 to 1825. This history isn't just for the tourists who come to see the Old Capitol Building or the Constitution Elm. It affects the property values and the way the zip code is perceived.
When you're looking at real estate in the 47112 area, you’re seeing a massive range. You’ve got historic 19th-century homes near the square that are worth a fortune because of their "bones." Then, five miles out, you have sprawling farmland and new builds. The zip code stays the same, but the lifestyle changes completely.
People move here because they want the "small town feel" without being isolated. You're 25 minutes from downtown Louisville. You get the 47112 taxes (which are generally lower than across the river in Kentucky) while still being able to catch a Cardinals game or hit up a high-end restaurant in the Highlands.
Beyond the Numbers: Life in Harrison County
What most people get wrong is thinking Corydon is a sleepy village. It's the economic engine of Harrison County. There’s a lot of industry here that people don't see from the historic district.
We're talking about massive limestone quarries. We're talking about the Tyson Foods plant which employs a huge chunk of the local workforce. These businesses all operate under that 47112 umbrella. The logistics of moving freight in and out of this zip code is a major part of the local economy. If you're looking for a job or starting a business, this is the zip code you want to be in.
Getting the Mail Right
If you’re moving here, here’s a tip: check your "Fire Number." In many parts of 47112, especially the rural stretches, the house number assigned by the county for emergency services might be different from what a GPS tells you. It’s rare nowadays with updated Google Maps data, but it still happens. Always verify with the Harrison County GIS department if you're buying land.
And don't forget the neighboring codes. You've got 47115 (Crandall), 47161 (New Salisbury), and 47136 (Lanesville). If you're right on the border, your neighbors might have a different code entirely, even if you share a fence.
The Logistics of 47112
Let's talk about the actual Post Office. It's located at 221 Business Blvd. It's not in the cute, historic downtown area—it's closer to the I-64 exchange. This is strategic.
- It allows for easier truck access.
- It's central to the newer commercial developments.
- It keeps the heavy mail traffic away from the narrow, historic streets.
If you have a PO Box in Corydon, you’re visiting this location. It’s a busy spot. On Saturday mornings, it’s basically a town meeting place. You’ll see everyone from farmers in overalls to tech workers who commute to the city.
Surprising Facts About the Area
The 47112 area is home to Squire Boone Caverns and Indiana Caverns. This isn't just trivia; it means the ground beneath the zip code is literally hollow in places. Construction in this zip code requires specific geological surveys. You can't just dig a basement anywhere in Corydon without checking for karst features.
Also, the 1863 Battle of Corydon happened here. It was the only organized battle of the Civil War fought on Indiana soil. When you walk through the parks in 47112, you're walking on a battlefield. The zip code preserves that history, but it doesn't stay stuck in it.
The local school system, South Harrison Community Schools, is another reason the 47112 zip code stays competitive. Parents specifically look for homes within this boundary. It’s a solid district with a lot of community support. That keeps property values stable, even when the rest of the market is wonky.
Common Misconceptions
People think 47112 is "just" Corydon. It's not. It encompasses several smaller unincorporated communities. If you say you live in "Corydon," locals might ask, "In town or out in the county?"
Another myth is that mail delivery is slow because it's "rural." Actually, because of the proximity to the Louisville UPS Worldport and the major USPS hub, mail in 47112 often moves faster than in more congested urban areas.
Actionable Steps for Using the Corydon Zip Code
If you’re interacting with the 47112 zip code for business, real estate, or personal reasons, here is how you handle it like a local:
For Real Estate Shoppers
Don't just rely on the zip code. Look at the township. Corydon is mainly in Harrison Township, but the zip code can bleed into others. Check the property tax rates specifically for Harrison County, as they differ significantly from Floyd County (New Albany) or Clark County (Jeffersonville). Use the Harrison County GIS map to see exact property lines and zoning.
For Business Owners
If you are shipping to 47112, always use the full Zip+4. It drastically reduces the "return to sender" rate, especially for the newer subdivisions popping up along Hwy 135. Also, be aware that while the zip code is 47112, your physical location might be outside the town limits, meaning you aren't subject to town-specific ordinances or taxes.
For Travelers and New Residents
If you're using a GPS to find an address in rural 47112, double-check the "North/South/East/West" designations. Harrison County uses a grid system for many of its county roads (e.g., SE Old Capitol Road). Missing a cardinal direction can put you five miles away from your actual destination.
For Government/Legal Documents
Ensure you specify "Harrison County." There is another Corydon in Iowa (zip code 50060) and one in Kentucky (42406). It sounds simple, but you’d be surprised how often legal filings or freight shipments end up in the wrong state because someone just typed "Corydon" and didn't check the zip.
The 47112 zip code is a gateway. It links the history of Indiana's founding to the modern economy of the Ohio River Valley. Whether you're mailing a letter or moving a family, understanding the layout of this specific area saves you time and money. It's a place where the 1800s meet the 2020s, all under one five-digit code.
