The delivery area includes limited street service along Virginia Avenue, complemented by one rural route that extends beyond the immediate postal facility. This rural carrier service pattern is typical for post offices that support both in-town PO Box customers and outlying addresses. The station operates as part of Cumberland's broader postal infrastructure, with most physical addresses in the area receiving mail through the neighboring 21502 ZIP code.
The extremely limited street presence reflects this facility's primary function as a PO Box station rather than a full-service post office with extensive delivery routes.
ZIP Code 21503 is designated for PO Box delivery only; business establishment and employment data are not available.
