You looked up a ZIP code to figure out where a house is. In Spring Hill and Thompson's Station, the ZIP tells you where the mail goes and not much more. It won't tell you which county the house is in, whether it's inside city limits, or which school it's zoned for.

I live in Canterbury, a 37179 neighborhood inside the Thompson's Station town limits, and on every house I look at in either town I check the county, the city limits and the school zone by the exact address. If you'd rather I check one for you, DM me, text or call 615-392-1186.

Is a Thompson's Station 37179 address always in Thompson's Station?

No. The Town of Thompson's Station says so on its own Community Development page: the Postal Service sets ZIP codes by delivery route, and they don't follow town or city boundaries. In the Town's words, 37179 "extends into the boundaries of the City of Spring Hill."

On the 2020 Census map, about 30 percent of 37179's land is inside the Town of Thompson's Station, about 7 percent is inside the City of Spring Hill, and the other 63 percent is outside both, in unincorporated Williamson County.

Why does it matter which side of the line a house is on?

The county and the city limits, not the ZIP, decide your property taxes, your school district and who handles zoning and permits for your home.

• Property taxes: inside Spring Hill, the city bills its own property tax separately from the county. Inside Thompson's Station, the Williamson County Trustee collects the town's tax. A home outside any city or town has no city tax on the bill. My Spring Hill property tax guide has the current rates for each side.
• Schools: the county picks the district. Williamson County Schools says you must live in Williamson County to attend, and its zone finder tells you to leave the ZIP code field blank and search by street address. Maury County Public Schools publishes a 2026-2027 street list of every school zone in the county. See my school guides for Spring Hill and Thompson's Station.
• Zoning and building permits come from the city or town inside its limits and from the county outside them.

How do I check the county and city limits for an address?

You can check any address with free public tools. This is the order I use.

1. Run the address through the U.S. Census Bureau's geocoder at geocoding.geo.census.gov and use the geographies search. It names the county and the city or town. If no city or town comes back, the house is in an unincorporated area.
2. For Spring Hill, open the City of Spring Hill's public GIS Data Viewer from the GIS page on springhilltn.org. It has city limits, county boundary and parcel layers.
3. For Thompson's Station, the Town's Community Development page lists its maps, including a ZIP code map and an urban growth boundary map.
4. Look up the school by street address with the district: the Williamson County Schools zone finder, or the Maury County Public Schools street list.
5. Before you write an offer, ask for the last tax bill. It shows which taxes the house actually pays.
