A Guide to Franklin, TN Zip Codes and County Boundaries

Franklin keeps pulling buyers out of the Nashville region, and it's not hard to see why. As of mid-2026, the median home sale price here sits around $863,530, homes are moving in roughly 48 days, and anyone buying a home in Franklin is getting specific about exactly where they want to land. They target the right street, the right zip code, and the right side of the county line.

That specificity matters more than most buyers expect. Your mailing address in Franklin determines property taxes, utility setups, and which county office handles your paperwork. The Nashville-Davidson-Murfreesboro-Franklin, TN, Metropolitan Statistical Area covers a lot of ground, and exact local zip codes help narrow the search.

The Main Zip Codes for Franklin, TN

Franklin covers a wide geographic area, so properties are spread across more than one postal route. The most prominent of those is 37064 - it covers a substantial portion of the town's residential and commercial real estate, and if you're searching for homes anywhere near that $863,000 median price, you'll see it constantly in listing data.

You'll also run into 37067. Together, these two codes dictate which local services handle your trash pickup, mail delivery, and utility connections. It sounds administrative, and it is - but it's the kind of detail worth sorting out before you're standing in a driveway trying to remember which box to check on the utility form.

How the 37064 Boundary Works

The 37064 zip code holds a real mix - historic properties, established subdivisions, and newer developments, sometimes a few blocks apart from each other. Property values and lot sizes vary widely within this single postal boundary, which means the five-digit code alone doesn't tell you much about what you're actually buying.

Across the broader Franklin market, available inventory currently sits at about 587 homes. If you're focusing on 37064, map those boundaries against your commute before you fall in love with a particular address. The zip code is large enough that two homes with the same first five digits can have meaningfully different drive times to the same office.

Where Franklin Sits in Williamson County

Franklin is located entirely within Williamson County. That's not a footnote - it's a core fact that shapes your property tax bill, vehicle registration, and access to regional government services.

Residents in the Nashville-Davidson-Murfreesboro-Franklin, TN, Metropolitan Statistical Area get a distinct local government while staying connected to the broader regional economy. Williamson County handles the administrative side for Franklin residents: court services, county-level property assessments, the works.

County Taxes and Services

Depending on where the property lines fall, a Franklin homeowner may pay both city taxes and Williamson County taxes - or just the county rate. A house just outside the incorporated city limits can look nearly identical to one inside it and carry a noticeably different tax obligation.

Verify the specific tax history for every home you tour. Your agent can pull that during the process. Exact Williamson County tax figures clarify your monthly carrying costs before you make an offer, preventing surprises at the closing table.

Exploring Franklin Neighborhoods by Zip Code

The parts of Franklin don't all feel like the same place, and that's worth understanding before you start narrowing your search. The Carter House - a Civil War-era historic home and site of the Battle of Franklin - anchors the historic core, and homes near that landmark tend to carry a premium tied to proximity to the town center and the preserved architecture around it.

Move away from the historic center and the character of the market shifts. Large-scale communities like Westhaven have their own layout, amenities, and commercial spaces, creating something closer to a self-contained environment within the broader Franklin market.

Matching Your Search to a Neighborhood

With homes currently selling for about 98% of list price, you don't have a lot of room to wander. Decide early where you want to be.

If the historic character near the Carter House is the draw, you're competing for a smaller pool of older homes. If the master-planned environment of Westhaven is more your speed, you're looking at different property types - often with different homeowner association fee structures attached. A specific neighborhood target makes your property alerts actually useful instead of just noisy.

Finding Your Full Nine-Digit Zip and Area Code

The standard five-digit code gets your mail to the right post office. The United States Postal Service's nine-digit ZIP+4 format takes it further - it pinpoints the exact street, block, or building. You'll need that full nine-digit number when setting up official documents, forwarding mail, or registering a vehicle in Williamson County.

Franklin residents also share a regional telephone area code with surrounding communities. When setting up local landlines or business contacts, you'll use the standard area code assigned to this part of the Nashville-Davidson-Murfreesboro-Franklin, TN, Metropolitan Statistical Area.

How to Look Up Your Specific Address

Type your new Franklin street address into the official USPS lookup tool. That's it. It gives you the exact ZIP+4, which then goes on your mortgage paperwork and utility accounts without any guesswork.

Do it as soon as your closing date is set. The correct nine-digit code prevents delays on your first utility bills and any tax documents coming from Williamson County - small hassles, but the kind that stack up right when you have enough going on already.

Frequently Asked Questions

Which Franklin, TN zip code has the highest property values?

While specific premiums shift, the most competitive zones near the historic core or within master-planned developments often push past the city's $863,530 median. Since local homes currently sell for roughly 98% of list price, buyers targeting these top-tier pockets need to prepare strong initial offers.

What is the main real estate difference between the 37064 and 37067 zip codes?

Beyond distinct utility connections and mail delivery routes, these two postal boundaries divide the city's 587 available homes into different commute zones. Buyers should map their daily drive from each area, as two houses with identical pricing can yield significantly different traffic patterns.

Do homes in all Franklin zip codes pay both city and Williamson County property taxes?

Postal boundaries do not determine your tax bill. Instead, buyers should verify the specific property lines, as a home's exact location dictates whether the monthly carrying costs include both city and county rates or just the county portion.

Are Williamson County school zones determined by my Franklin zip code?

No - school zones are determined by specific neighborhood boundaries and street addresses, not the five-digit zip code. Two homes in the 37064 zip code can be zoned for completely different facilities.

Which zip code includes historic downtown Franklin and its walkable neighborhoods?

The 37064 boundary encompasses the historic core and the Carter House, but this single code also contains newer developments and established subdivisions. Buyers targeting older architecture should focus their search on the specific streets surrounding the Civil War-era landmarks rather than using the broad five-digit code.

Which Franklin zip codes currently have the most new construction homes for sale?

While the city's 587 available homes include a mix of ages, buyers seeking new builds typically find more options as they move away from the historic center. Areas featuring master-planned communities generally offer different property types and homeowner association fee structures than the older central districts.
