Postal Service Overview

Childs operates as a PO Box ZIP code in Cecil County, Maryland, where 94 PO Boxes serve a small community centered on Blue Ball Road. The ZIP has just one street route covering Blue Ball Road, with 21 businesses maintaining mail service alongside residential boxes. The post office handles delivery through a mix of rural routes (two carriers) and general delivery, typical for Maryland's rural northeastern corner near the Pennsylvania border.

Mail Service Pattern

This isn't a street-delivery community. The ZIP has essentially no measurable land area in standard postal metrics and contains no traditional neighborhoods, though it's enclosed within the larger 21921 ZIP code area. The 94 PO Boxes far exceed the single identified residence, suggesting the post office serves as a mail hub for scattered rural properties and small businesses that don't appear in street-delivery databases. Cecil County's agricultural character means many addresses rely on PO Box service rather than roadside delivery.

Street Name Patterns

Rural Roads Single Street Community

With only Blue Ball Road appearing in ZIP+4 records, Childs represents a minimal street-delivery footprint where PO Box service dominates. The single street name suggests a crossroads community rather than a developed town grid.
