Ellerslie sits in western Maryland's Allegany County, less than a square mile of compact rural community near the Pennsylvania border. With 651 residents and 279 households, this small town has operated under PO Box classification since before 2004, when USPS began tracking ZIP code introduction dates.
This is a PO Box Only Zone. There's no alternative mail delivery across the territory. The post office maintains 332 PO Boxes for 279 households, resulting in a 1.19 adoption rate that indicates service extending beyond immediate residents. Rural carrier routes R001 and R002 serve some addresses, but most residents rely on PO Boxes.
Ellerslie's character comes through in its street names. Ellerslie Road has the most delivery points with 23 addresses, followed by Kings Grove Road with 11. Nature-themed streets dot the landscape: Pin Oak Court, Red Maple Lane, Wild Cherry Lane, Black Walnut Lane, Whitetail Lane. Mason Dixon View acknowledges the nearby state line. Many homes include basement apartments (BSMT units), common in older housing stock.
Nearly all housing dates from before 1939. With a median age of 47 years, this isn't a college town or retirement village, but a working community. Transportation dominates employment: 181 workers (out of 466 adults over 25) work in transportation, warehousing, or utilities. Another 90 work in education and healthcare, and 45 in public administration. The median household income of $34,167 and median home value of $145,200 indicate a modest, working-class community.
Ownership rates run high at 76% (212 of 279 occupied homes). The population is 94% White, with 17% identifying as Hispanic or Latino. Just 3.1% of adults hold bachelor's degrees, and 98% were born in the United States. With only 27 vacant units and zero seasonal properties, this is a year-round residential community without vacation or second-home character.
