<1>If you're interested in how the shape of Pennsylvania's counties, including Mercer, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The elevation is an estimate for the area around Millbrook - it will be higher in some places and lower in others.
<3>When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 412 code has been Overlayed with one of the following codes: 724 or 878. New phone numbers in the Millbrook area will be assigned with one of these codes: 412, 724 or 878. As a result, placing a call in the Millbrook area will require 10-digit dialing (where you enter both the area code and then the phone number).
