This is a PO Box Only zone, meaning there's no alternative mail delivery available. Two rural carrier routes serve street addresses, but the community relies primarily on post office boxes. The adoption rate of 1.10 shows the post office serves customers beyond just the immediate town, extending mail service to neighboring rural areas.
Street delivery is minimal, with only two streets recorded in the ZIP+4 database: State Route 260 and E Weston St. This reflects the community's reliance on PO Box service rather than door-to-door delivery.
