The high adoption rate isn't unique to any particular demographic pattern here. The Census shows a median age of 49.2 years, with 73 White residents, 16 Black residents, and a mixed-age population that doesn't fit university, retirement, or institutional profiles. What drives the regional demand is geography: Morganza sits in a 0.16-square-mile area where street delivery options remain limited, making the post office a draw for surrounding communities in rural Saint Mary's County.
The ZIP contains minimal street infrastructure. Doctor Johnson Road accounts for 2 ZIP+4 records, the most of any street, followed by single-record entries for Goodrick Lane, Colton Point Road, and Preensou. There's one city carrier route and one general delivery route, plus 5 PO Box routes. The presence of street delivery confirms this isn't purely a PO Box-only operation, but the dominance of box routes shows where the real volume lies.
The post office building itself appears in the ZIP+4 data as "Postmaster," indicating the facility serves as both a service point and administrative address. With just 11 businesses recorded in the ZIP and 3 establishments employing 8 people, Morganza functions more as a mail access point than a commercial center. Residents from areas without carrier delivery travel here to pick up mail, explaining why box adoption exceeds local household counts by more than double.
Street names reflect rural Maryland character, with Doctor Johnson Road being the most developed thoroughfare. The limited street count and single-digit record counts per street confirm this is a small, low-density service area where most mail goes to PO Boxes rather than street addresses.
ZIP Code 20660 has 107 residents and 29 households (average 3.69 persons per household).
