McGrann is a small community in Armstrong County, Pennsylvania, with 250 residents living in 109 households across just 0.08 square miles. This compact hamlet occupies a fraction of a square mile along what appears to be historic riverfront territory, with street names like Riverside Drive and Railroad Drive hinting at its industrial past.
This is a PO Box Only Zone. There's no alternative mail delivery anywhere in the area. The McGrann post office maintains 120 PO Boxes for 109 local households, with the adoption rate of 1.10 suggesting a few boxes serve nearby addresses outside the immediate ZIP boundary. Every resident and business uses a PO Box for mail. Limited rural and city carrier routes exist (one route each), but these deliver to PO Boxes using the PO Box Street Addressing system, not to homes.
McGrann has a distinctly historic character. Of the 118 total housing units, 92 were built before 1939. That's 78% of the housing stock predating World War II. The median home value sits at $83,100, and the homeownership rate is 75% (82 owner-occupied units out of 109 occupied homes). With a median age of 46.7 years and per capita income of $16,981, McGrann fits the profile of a working-class Pennsylvania hamlet where many families have lived for generations.
The street network includes 14 named streets serving fewer than 20 street delivery records. Byron Street has the most addresses with 5 records, followed by Cherry Way with 2. Most streets (Centre Alley, Hill Street, School Street, Grant Street) have just a single delivery point each. This limited addressing infrastructure is typical of small communities that consolidated around PO Box service decades ago.
All mail must be addressed to a PO Box:
