Happy Anniversary to the Monroeville Post Office!
Established January 23, 1851, the post office celebrates 175 years of service today.
Postal Code “Monroeville” 15146 - A History of Monroeville Post Offices
Before the sprawling suburbs and bustling highways defined the landscape east of Pittsburgh, the area known as Patton Township was a quiet collection of farming homesteads. By 1850, these farms coalesced into a small village. Even with the developing sense of community, there was a lack of fundamental connection to the outside world: a local mail service. To post or receive letters, residents were forced to make the arduous trek south to Turtle Creek, whose post office opened in 1826.
Eventually residents could make a less arduous trek north to “Clugston” when its post office opened in 1847. Where is Clugston? When it applied for a post office, it was described as a thriving settlement near the intersection of Logan’s Ferry, Haymaker, and Center roads. For more information, read The Lost Village of Clugston.
The Birth of “Monroeville”
In a move that would permanently name the community, early settler and prominent landowner Joel Monroe organized his neighbors and petitioned the federal government for a local post office, dubbing it “Monroeville”.
Following the naming conventions of the mid-19th century, the office required a title with local significance. The community chose to honor its first postmaster by adding a suffix to his name—thus, Monroeville was born.
For the petition to succeed, it needed sufficient community support that demonstrated how the business of the village would benefit from a local postal depot and that, of course, the depot would be self-sustaining. Afterall, postmasters were paid based on the amount of mail they handled so the United States Post Office Department wouldn't open a local depot unless there were enough residents to generate postal revenue.
The 1850 Census, recorded a total population of 453 residents in Patton Township, however, only a cluster of those residents lived in the immediate vicinity of what we now call Monroeville. While the Monroeville Historical Society hasn’t located a copy of the petition it is likely that 25 to 30 signatures (of male heads of households) were needed to justify a local postal branch for the village of frontier farming families.
The community’s effort was successful, and on January 23, 1851, the USPOD signed the commissioning paperwork to establish the Monroeville post office with Joel Monroe as its first postmaster.
A Wandering Post Office
The government rarely built dedicated buildings for small towns. Instead, it relied on a contractual arrangement with the appointed postmaster. Since the postmaster was paid based on a commission of the stamps he sold (usually a few dollars a year for small offices), he was expected to provide the space himself—which is why the first Monroeville Post Office was in a corner of Joel Monroe’s own farmhouse. His home, which was centrally located for the residents, sat near the toll gate of the Northern Turnpike toll road. Today, this is the intersection of William Penn Highway (Route 22) and Northern Pike (across from the Municipal building).
In the decades that followed, the post office moved frequently, often shifting to the home or business of whoever held the postmaster appointment. Staffing the post office was frequently a family affair, as in the case of Eli Meyers who managed the postal office from the stockroom of his retail store and enlisted his daughters Virginia “Etta” and Margaret to sort the mail.

Rural Free Delivery (RFD)
In the early years, mail was a luxury and required patience since deliveries were processed only on Saturdays. Eventually service expanded to three days a week (Monday, Wednesday, and Saturday) before finally becoming a six-day-a-week operation.
Establishing Rural Free Delivery (RFD) changed things and is arguably one of the most significant modernizations in American history and a significant turning point for the Monroeville post office. Before the implementation of RFD, the Monroeville office was a "fourth-class" station, meaning residents had to travel to the post office to check for mail. However, this new federal initiative brought mail directly to the farmhouse gate!
The national RFD experiment began in 1896 and reached Western Pennsylvania in waves as local offices provided maps of the serviceable roads in their area. For Monroeville, records indicate that rural routes started between 1900 and 1902. This coincided with the appointment of William R. Johnston as Postmaster in 1902.
Post Office On Wheels
RFD fundamentally changed the job of the postmaster. Previously, they sat and waited for the public; with RFD, the post office went to the people. The mail now arrived from Turtle Creek, then sorted by the postmaster, then delivered to local homes by a mail carrier. At first deliveries were made by horse and buggy but transitioned to automobiles as they became prevalent. Except of course, on those rainy, muddy days when a car could get stuck and reliable ole Nelly would come out of the barn.
These mobile post offices didn't just drop off letters; they sold stamps, processed money orders, and registered letters. Carriers typically covered 20 to 25 miles a day. In Monroeville's hilly terrain, before slag dumps leveled much of the area, negotiating the delivery routes was grueling work even with the strict requirement that roads must be passable year-round to maintain RFD. This pressured local Patton Township supervisors to improve the dirt paths that would eventually become the paved roads of our modern borough.
The arrival of the mailman in the RFD days was a welcomed sight. It was Homer Johnson who delivered mail around the community for over thirty years, many of those in his old Model A Ford. In the end, Mr. Johnson clocked some 235,000 miles in that old car, faithfully delivering mail to the residents of Patton Township.
Interestingly, during the 1930s, the Monroeville area was part of a unique aerial pick-up system. Planes would snag mail bags from poles located at Bohinski Field (now Community Park West) without landing, a system designed to speed up service to small towns.

Thoroughly Modern Mail
The RFD system used unique route numbers to identify locations rather than street addresses. This lasted until the mid-20th century when the government phased out RFD and implemented the street and house numbering system we use today. The timing aligned perfectly with Patton Township’s transition from rural farmland to the growing suburb of Monroeville. It was time for a dedicated post office building.
While the historical society doesn’t have the exact ribbon-cutting date, the first standalone post office facility opened in the 1970s at 4039 Monroeville Blvd. Many know the building as the current location of Labriola’s Market. During construction, the post office operated out of the Annex Shops at the Monroeville Mall which opened in 1969.
The postal service constructed the dedicated facility on Monroeville Boulevard to handle the increasing demand and designed the building Modernist style typical of the USPS during that era, prioritizing function, large loading docks for trucks, and a simple exterior. The choice to build in the area of Monroeville Boulevard was strategic. By the 1970s, the road had become a primary connection between residential neighborhoods and the commercial corridor of Route 22. Mail trucks could easily access the highway while keeping retail traffic separate from the heavy mail-sorting operations. Eventually, volume again surpassed the facility’s capacity and a new building located on a larger campus at 2630 Monroeville Blvd opened in the 1990s.
From a few handwritten letters sorted on a farmhouse table to a modern postal campus serving a thriving municipality, the story of Monroeville’s post office mirrors the evolution of the community itself. Each move, innovation, and expansion reflected the changing needs of resident farmers, shopkeepers, families, and eventually suburban neighborhoods, while maintaining the same essential purpose: connection. For 175 years, the Monroeville post office has quietly linked its residents to one another while linking Monroeville to the wider world and giving our community its identity.
