Don’t let a ZIP Code fool you, especially where Williamson County is concerned.

Consider the “Brentwood” Goodwill store. It has a 37027 Brentwood address, is located in SE Davidson County and is within spitting distance of Nolensville — 37135.

And then there’s this recent listing for a three-bedroom, three-bath, all-brick home “located in a private gated community in the heart of Brentwood.” You won’t find it in exclusive Governor’s Club. This single-family, Brentwood Chase home isn’t in the City of Brentwood at all. Despite its Brentwood address – and 37027 ZIP — it’s in Metro Nashville just north of Old Hickory Boulevard.

No wonder people get confused knowing where they are, and sometimes where they live.

Take northwest Williamson County’s new, self-proclaimed “town” of Stephens Valley. The first families moving into the 980-acre mixed-use development have Nashville (37221) addresses but their children are zoned for WCS’ Fairview (37062) campuses.

In Spring Hill (37174), things get hairier still. Not only is the city split between Williamson and Maury counties, several of Spring Hills’s northern subdivisions sit in Thompson’s Station 37179 postal zone.

Many homeowners in those neighborhoods consider that a happy coincidence because of the rural town’s cachet.

Leiper’s Fork, the historic village that’s as cool as it is country, in recent years has become the county’s hippest destination to live or visit. But don’t look for an embroidered pillow or painted wood plaque with the Fork’s ZIP Code in one of its art galleries or gift boutiques. Sadly, this special place doesn’t have a ZIP to call its own.

As popular as it is, when it comes to the Post Office, Leiper’s Fork is just Franklin 37064.
