<div dir="ltr">As for Bryce's observation - Zillow does not have overlapping polygons as far as I know, so it is by its nature sort of rigid - but then again this is probably what they require for their use case, as there would be no way to disambiguate.<div>

<div dir="ltr">Yea, I think this is where sources like Geonames and Zillow, which are built (to an extent) based on actual perceived names rather than official ones, could be so valuable - and why GNIS populated places are detrimental to OSM map quality, at least in many urban areas.</div>

According to the post office, my house is in the Woodbine postal district, named after a small town that was subsequently swallowed up by the expansion of Nashville. However, when people refer to the Woodbine area, they usually mean the approximate area of the old town, several miles from my house.<br>
<br>
I usually refer to my neighborhood as Antioch, the name of another small town that has expanded outward, even though the official border of Antioch, according to the post office, is about 300 feet from my house.<br>
