Coverage
Berks County, End To End
Reading, and Berks County around it. Whether a given address falls inside that is settled by the ZIP code on the form, which matters more here than it would elsewhere, since Berks shares a border with six other counties.
Reading
The city itself, where the constraint is usually an alley, a narrow side yard or a garage apron rather than distance.
Mohnton and Birdsboro
South and southeast along the river, older housing mixed with wooded lots that back onto nothing in particular.
Boyertown, Bally and Mertztown
The eastern corner, where properties get larger and driveways get longer.
Fleetwood, Blandon and Topton
Northeast of the city, village lots and the farm ground between them.
Kutztown
Further northeast, a borough surrounded by open country on every side.
Hamburg, Leesport and Shoemakersville
North along the Schuylkill, where the valley narrows and the wooded ground comes close to the back of properties.
Bernville, Robesonia, Wernersville and Womelsdorf
West of Reading, farmland and small boroughs where access is the whole question.
Oley, Douglassville and Morgantown
Southeast toward the county line, long lanes and outbuildings on most calls.
Near the county line?
Six other counties share a line with Berks, and a mailing town on your envelope is not always the county your house actually stands in.
Send it anyway. What decides the destination is those five digits, not the name on this website, so an address belonging to somebody else's territory gets handed to them rather than quietly absorbed here.
This means private ground
Roads are a different question, and the answer changes with the class of road. Each one, with its source.
