Pennsylvania Parcel Maps & County GIS Viewers

Sixty-seven Pennsylvania counties publish local tax parcel maps. This hub is the outbound directory to those official GIS viewers.

PIN / UPI search across PA

Platbookmapper links out; we do not host Pennsylvania parcels. Pick a county, open its GIS, and search by PIN/UPI, address, or owner. Southeastern metro counties offer dense urban fabrics; northern and western counties show larger rural tracts and coal-region quirks.

Pennsylvania uses metes-and-bounds and warrants/patents historically—not a western PLSS grid. Parcel identifiers (PIN, UPI) are county-defined. Municipalities assess within counties; choose the county GIS that matches your tax bill. Floodplain layers along major rivers are common planning overlays.

Online lot lines orient research. They are not surveys—use recorded plans or a licensed surveyor for legal work.

UPI/PIN hyphens vary by county; do not “fix” formatting. Coal-region annotations, when shown, are not surface lot lines. Prefer the county GIS listed here over random statewide scrapers. We link out exclusively.

Municipal assessment still sits inside county GIS for most research workflows—confirm municipality name in the popup. Prefer PIN paste over retyping long strings.

County GIS migrations happen; this hub is meant to stay the simple A–Z jump list so you are not dependent on memorized deep links we do not control.

Frequently asked questions

How do I find a Pennsylvania county parcel map?

Pick your county on this Pennsylvania hub (or on the national Platbookmapper map), then open the official GIS / parcel viewer link. Each county maintains its own app — we link out and do not host parcels.

Are Pennsylvania online parcel maps survey-grade?

No. County GIS parcels are tax and planning layers. For legal boundaries, use a recorded plat or hire a licensed surveyor.

Why do some Pennsylvania counties say Verify via map?

We only mark a county Listed when we have a curated direct interactive viewer URL. Verify counties still open from the national map with the best available outbound link — always confirm it is the official local source.

Does Platbookmapper draw property lot lines?

No. We do not host or redraw parcel geometry. Our product is a USA → county → official GIS link directory so you can open the local interactive map in a new tab.
