How many ZIP codes Franklin has, and which ones have homes
Franklin uses five ZIP codes. Only three of them are delivery areas with streets: 37064, 37067 and 37069. The other two, 37065 and 37068, are classified as PO box ZIP codes, so no house or lot carries them as its address. If you are searching for a home, you are searching in 37064, 37067 or 37069, or in the countryside ZIPs that sit beyond the city.
| ZIP | Type | Land area (Census 2020) | Zillow typical value, Aug 2026 |
|---|---|---|---|
| 37064 | Streets and homes | About 184 sq mi | $911,270 |
| 37065 | PO boxes only | None (no delivery area) | None |
| 37067 | Streets and homes | About 32.5 sq mi | $953,759 |
| 37068 | PO boxes only | None (no delivery area) | None |
| 37069 | Streets and homes | About 35.9 sq mi | $1,023,572 |
| 37046 (College Grove) | Streets and homes | About 71.4 sq mi | $1,300,186 |
| 37014 (Arrington) | Streets and homes | About 22.0 sq mi | $1,273,897 |
The PO box classification comes from Zip-Codes.com's ZIP records; land areas are Census ZIP code tabulation areas, which approximate USPS delivery areas but are not identical to them. Neither PO box ZIP appears in the Census land-area figures or in Zillow's home values used on this page, because neither covers any homes. To confirm the ZIP for a specific address, use the USPS ZIP Code lookup on the property address, not the owner's mailing address, which may be a PO box.
A Franklin address is not always the City of Franklin
The single most useful thing to know about Franklin ZIP codes: most of their land is outside the city. Census figures for the 2020 ZIP code tabulation areas (the Census version of ZIP codes, close to but not identical to USPS delivery areas) show that only about 25 of the roughly 184 square miles in 37064 are inside the City of Franklin. The rest is mostly unincorporated Williamson County.
That matters for two costs. A home inside city limits pays a City of Franklin property tax rate on top of the county rate, while an unincorporated home pays the county rate only; Williamson County property tax has the 2026 rates and an example bill. And the public school district depends on the address, not the ZIP: Franklin schools explains how to check. Boundaries here are from 2020, and the city has annexed land since, so confirm any specific parcel with the county.
Each Franklin-area ZIP code at a glance
Values below are Zillow's typical home value for August 2026, which reflects the middle of each ZIP's market, not its $1M+ homes. Land areas come from the Census 2020 ZIP-to-place relationship file.
37064: the largest Franklin ZIP
37064 covers about 184 square miles of land and holds the biggest piece of the city, about 25.1 of Franklin's roughly 42.75 square miles. About 153 square miles are outside any incorporated city, and the ZIP also reaches into part of Thompson's Station and a small piece of Nashville-Davidson. Zillow's typical value was $911,270, up 2.27% in a year, 31.77% over five years and 110.46% over ten. It is the lowest of the five ZIPs here, so a $1 million budget sits above its typical home.
37067: the most city land for its size
37067 is far smaller, about 32.5 square miles, and about 12.0 of them are inside the City of Franklin. That makes it the Franklin ZIP with the largest share of its land in city limits, a little over a third. About 20.6 square miles are unincorporated, with a tiny overlap into Brentwood. The typical value was $953,759, up 2.69% in a year and 34.28% over five years, the fastest five-year gain of the three Franklin ZIPs.
37069: the highest-value Franklin ZIP
37069 covers about 35.9 square miles, but only about 5.3 are inside the city; about 30.6 square miles are unincorporated, with a tiny overlap into Brentwood. Its typical value was $1,023,572 in August 2026, the only one of the three Franklin ZIPs above $1 million, up 3.15% in a year and 111.42% over ten years.
37046: College Grove
College Grove's 37046 covers about 71.4 square miles, almost all outside any incorporated city, with a sliver overlapping Eagleville. Its typical value was $1,300,186, the highest of the five, up 2.77% in a year and 136.81% over ten years. For land, communities and services there, see College Grove.
37014: Arrington
Arrington's 37014 covers about 22.0 square miles, also almost entirely unincorporated, with a sliver overlapping Smyrna. Its typical value was $1,273,897, up 2.67% in a year, 36.20% over five years and 138.96% over ten, the largest ten-year gain of the five. Zillow's city-level figure for Arrington is lower, $1,174,298, because Zillow draws the town and the ZIP differently.
37065: PO boxes only
37065 is a Franklin ZIP code made up of post office boxes. Zip-Codes.com classifies it as a PO box ZIP, notes that it covers no residential streets, and places it inside the 37064 area at the Columbia Avenue post office. No home is addressed to 37065, so no home value or land area exists for it. You may still see it on deeds, tax bills or HOA records when an owner receives mail at a box, which is why the property address and the owner's mailing address can carry different ZIPs.
37068: PO boxes only
37068 is Franklin's second PO box ZIP code, listed by Zip-Codes.com as a PO box classification rather than a delivery area. Like 37065, it has no homes or streets, so it never appears as a property's location. If a listing, a county record or a lender's file shows 37068, check whether it is a mailing address before you rely on it to place the home, its tax jurisdiction or its school district.
37027: a sliver of the city
About 0.33 square miles of the City of Franklin fall in 37027, which is Brentwood's main ZIP. Zillow's typical value there was $1,235,638 in August 2026. Brentwood is a separate market and isn't covered on this site, but the figure is a useful benchmark.
Which Franklin ZIP code costs the most
Ranked by Zillow's typical home value in August 2026, the order is 37046 College Grove ($1,300,186), 37014 Arrington ($1,273,897), 37069 ($1,023,572), 37067 ($953,759) and 37064 ($911,270). Among the three Franklin ZIPs, 37069 is the most expensive by about $112,000 over 37064.
A ZIP average hides a wide range. Zillow's own Franklin neighborhood areas ran from $580,552 (Southall) to $1,426,530 (McLemore) in the same month, so the street and the lot matter more than the ZIP.

Yes. Both are Franklin ZIP codes, but they are reserved for post office boxes and cover no streets or homes. You will see them on mailing addresses, not on property locations.
