This is a true PO Box-only zone. The streets here don't get carrier delivery from alternative ZIP codes, making the post office the sole option for residents in this peninsula community. The pattern is typical for waterfront areas in southern Maryland, where long driveways and sparse development make traditional mail routes impractical. Nine businesses maintain addresses here, most likely marinas, seasonal operations, or services catering to the waterfront properties that define this peninsula.
Street names reflect the waterfront character of this Saint Mary's County peninsula, with Porpoise Creek Lane leading to scattered points along the Potomac shoreline.
ZIP Code 20627 is designated for PO Box delivery only; business establishment and employment data are not available.
