About this directory

A public preview of 9352 active corporations and LLCs registered in Jefferson County, NY, built from open government data. Free to browse, non-commercial, refreshed periodically.

Data sources

Registered businesses come from the NY Department of State's active corporations register, refreshed monthly. State licence registers, Overture Maps open data, the Chamber's member directory and businesses' own websites add categories, contact details and businesses that are not corporations. The full list, with licences and refresh dates, is on the data sources page.

What's not here yet

Sole proprietorships and DBAs. When someone operates as "Smith Lawn Care" without forming an LLC or corporation, they file a Certificate of Assumed Name with the Jefferson County Clerk, not with NY State. Those records aren't currently in this directory. Many one-person handymen, gardeners, masons, and snowplow operators in the North Country operate this way — so this directory undercounts them. Open map data (Overture Maps) fills part of this gap; a request to the Jefferson County Clerk is on the roadmap.

Coverage of Jefferson County itself

Of the 23 municipalities in Jefferson County (population ~117,000), only the City of Watertown publishes parcel data via a public GIS service. The other 22 towns — including Le Ray, which hosts Fort Drum — are opaque to public GIS because Jefferson County did not opt in to the NY State Statewide Parcel Program. We cover that gap separately.

Categorization

Each business is tagged with a primary trade/business category from keywords in its registered name, from the type of any state licence it holds, or from open map data that matches its name. Many entries remain uncategorized because their names are person-based or generic (e.g., "JKM Holdings LLC") and no other source describes them. False positives are rare; false negatives are common. If your business is miscategorized, contact us — this preview is intended to improve.

What this directory is for

This is a public preview while we figure out the right way to serve Jefferson County. Existing options (the chamber of commerce site, Google Maps, paper Yellow Pages) miss the long tail of small operators that actually run a lot of local business. We want to make those discoverable.
