Libertytown's post office serves far beyond its borders. With 196 PO Boxes supporting a local population of just 233 people across 95 households, the adoption rate of 2.06 means this facility maintains twice as many boxes as local households. That's not a measurement error. It's evidence of regional service to surrounding rural areas in Frederick County where carrier delivery isn't available.
The ZIP code itself covers just 0.016 square miles, making it one of Maryland's smallest by area. Yet it serves customers from a much wider geographic footprint. Four rural carrier routes (Route R) operate from this location, alongside one general delivery route and nine PO Box routes. The facility manages 14 ZIP+4 records covering only three streets: Main Street (with 2 delivery records), Liberty Road, and Searieli Road. One named building appears in postal records: the Postmaster facility itself.
This isn't a traditional town center with dense housing. The 233 residents live in a ratio of 2.45 people per household, typical for family homes. The median age of 37.1 years reflects a working-age population. Census data shows 164 white residents (70%), 34 residents of two or more races (15%), and smaller populations of Black (19), Asian (7), and other residents. The 28 Hispanic residents represent 12% of the total population.
Of the 98 total housing units, 95 are occupied and only 3 stand vacant. There are no seasonal or vacation properties here. The single-family character dominates, with minimal multi-family development. Employment data shows 36 residents work in educational services, healthcare, and social assistance, while 52 work in other sectors. No residents work from home according to available data. Business statistics from 2003 counted 12 establishments employing 67 people, though the current count shows 51 businesses maintaining PO Boxes at this location.
The high PO Box adoption tells the real story. Surrounding communities without their own carrier delivery use Libertytown as their postal hub. The post office doesn't just serve local residents—it functions as a collection point for a dispersed rural population across Frederick County's less-developed areas. That's why a town of 95 households supports nearly 200 PO Boxes. It's a regional service center for mail, even if it doesn't look like one on a map.
Only three streets appear in postal delivery records, reflecting Libertytown's extremely compact geographic footprint of 0.016 square miles. Main Street has the highest concentration of delivery points, while Liberty and Searieli Roads each have single delivery records. The limited street network contrasts sharply with the 196 PO Boxes maintained at this facility, emphasizing that most customers come from outside the immediate town boundaries to collect mail.
ZIP Code 21762 has 233 residents and 95 households (average 2.45 persons per household). The median age is 37.1 years, slightly younger than the state (38.8) and slightly younger than the nation (38.8). The gender split is 52.8% male and 47.2% female, which is higher than the state male share (48.2%), making this a male-majority area. Largest groups are White (70.4%, much higher than the state average of 48.7% and well above the national average of 61.6%) and Black or African American (8.2%, much lower than the state average of 29.5%); Hispanic or Latino residents make up 7.3%, which is much lower than the national average (18.7%).
