The neighborhood map is an official city layer

The Hill, The Ville, Carondelet Neighborhood, and Soulard Neighborhood are everyday St. Louis names, but the City also treats neighborhoods as a map layer. Its neighborhood map includes an address lookup that ties an address to neighborhood, ward, and contact information.

That keeps a casual label from doing too much work. A listing, landlord, neighbor, or old family habit may use a name loosely. The City boundary layer is the cleaner starting point when the question is aldermanic service, neighborhood stabilization, planning, or which local contact goes with a block.

Use the neighborhood name as one layer, not the whole answer. After the map places the address, the next checks are the ward, zoning, permits, and service-request tools that fit that exact spot. St. Louis identity is local, but city services still run on mapped boundaries.
