How Rural Postal Service Works Here

The postal designation reflects how rural New England handles mail service. Rather than extending carrier routes to every scattered residence, the post office serves as a central pickup point. The 24 businesses and 183 PO Box holders use the Cornish Flat address, though many likely receive packages or oversized mail through the neighboring ZIP 03745, which geographically encloses this PO Box zone. That's typical for rural New Hampshire, where PO Box ZIPs coexist with larger carrier-route ZIPs that handle the actual residential delivery.
