Southampton spans the South Fork from the Shinnecock Canal east, and includes several incorporated villages with their own governance. Tax map numbers begin with district 0900. Lot sizes here skew far larger than the western towns, and much of the shoreline falls within mapped tidal wetlands. The Town publishes both its zoning schedule and its 2009 FEMA flood map to a public GIS, and both are mapped here — the zoning districts are the most descriptively labelled of any Suffolk town, naming the minimum lot size directly (R80 is Residence 80,000 square feet).
How to read a Southampton tax map number
Suffolk County identifies every parcel by a 19-digit Suffolk County Tax Map number (SCTM). It is written in four parts, and each part narrows the location:
- District
- 0900 — the town. Every parcel in Southampton begins with these four digits.
- Section
- A numbered map sheet within the town.
- Block
- A group of parcels on that sheet, usually bounded by streets.
- Lot
- The individual parcel. Sub-lots appear after the decimal when land is split.
A Southampton tax map number therefore looks like 0900-123.00-01.00-005.000. Unlike a street address it does not change when the property is sold, which is why deeds, tax bills and assessment records all key on it.

About this data
ParcelIntel is built and operated by Chokdee Properties LLC, a home builder working in Suffolk County. We assembled this map because we needed it ourselves — to check lot lines, zoning and wetlands before committing to a parcel. Parcel geometry comes directly from the Suffolk County tax parcel layer and attributes from southampton; nothing here is modelled or estimated.
It is a reference tool, not a survey. Boundaries are as digitised by the County and are not a legal determination of title, buildability or regulatory status. For those, consult the Town of Southampton and a licensed surveyor.
