The facility serves a limited footprint with a single rural carrier route alongside its PO Box operations. Eastern Avenue is the only street with dedicated ZIP+4 records in the system, showing two delivery points. Most customers use PO Box service, though the post office also manages delivery through one rural route and one general delivery classification. The presence of 90 PO Boxes for a zone with minimal residential street coverage suggests the facility primarily handles business mail and serves as a collection point for customers who prefer PO Box service over street delivery alternatives available in adjacent areas.
