Stillwater, New Jersey operates as a PO Box ZIP serving 74 boxes through a small post office on Main Street. While classified as a PO Box-only ZIP, residents don't lack street delivery. They receive it through neighboring ZIP code 07860, which surrounds this postal facility. The post office maintains two rural carrier routes that serve households scattered along Stillwater Road and Middleville Road.
This arrangement is typical for small crossroads communities in Sussex County. The post office itself sits at a central intersection, offering PO Box service to those who prefer it while street addresses receive mail via the larger neighboring delivery zone. The 16 businesses and handful of residential boxes reflect a quiet rural setting rather than a distinct town boundary.
Just three streets in postal records show this is a small crossroads community. Main Street hosts the post office, while Middleville and Stillwater roads extend into surrounding rural areas served by carrier routes.
ZIP Code 07875 supports both business and residential activity. According to the Business Census (2024), there are 9 business establishments, employing about 110 people with an annual payroll of $4,907,000.
