The Southern Tier is not a legally defined region. Due to this, various neighboring counties can be included in the region, while counties near other regions of New York State may be excluded. For example, some organizations consider [[Delaware County, New York|Delaware County]], [[Otsego County, New York|Otsego County]], [[Schoharie County, New York|Schoharie County]] and [[Cortland County, New York|Cortland County]] to reside in the Southern Tier.<ref>{{Cite web |title=Southern Tier |url=https://www.lookupstateny.com/moving-to-upstate-new-york/regioncounty/southern-tier |access-date=May 20, 2024 |website=Look Upstate NY}}</ref><ref>{{Cite web |title=Southern Tier of New York Regional and Economic Profile |url=https://southerntier8.org/regional-profile/ |access-date=May 21, 2024 |website=southerntier8.org |language=en}}</ref>

Other definitions define it as comprising the combined Corning-Elmira-Binghamton [[Metropolitan Statistical Area]]s, which includes Steuben, Chemung, Tioga and Broome Counties but not Chautauqua, Cattaraugus or Allegany, which are considered [[Western New York]]. 

The New York State Division of Local Government Services presently classifies the following fourteen counties as members of the Southern Tier: Allegany, Broome, Cattaraugus, Chautauqua, Chemung, Chenango, Cortland, Delaware, Otsego, Schoharie, Schuyler, Steuben, Tioga, and Tompkins.<ref>

This region is most commonly known as New York's "Southern Tier."}}</ref> This definition corresponds to the same 14 counties in New York State that are members of the [[Appalachian Regional Commission]] formed in 1963.

Much of the Southern Tier is in [[area code 607]], with the exception of Allegany, Cattaraugus, and Chautauqua Counties, which are in [[area code 716]] or [[area code 585]]. As of 2023, the westernmost portion of the Southern Tier is located in [[New York's 23rd congressional district]], and the easternmost portion is located in [[New York's 19th congressional district]]. The ZIP code prefixes 147 (Jamestown region), 148 – 149 (Elmira region), and 137 – 139 (Binghamton region) are set aside for the Southern Tier.
