How to read Pennsylvania sex offender counts by ZIP code. Four things to know before comparing two Pennsylvania ZIPs.

01A ZIP code is a mail-delivery area, not a boundary a registry uses. One ZIP can cross city and county lines, and a Pennsylvania address may be filed under a neighboring town’s name — so each ZIP is counted by the ZIP on the address, and the city and county pages count their own boundaries. The two will not add up exactly, and that is expected.
02The count is the registrants we index with that ZIP as of October 2026, rounded and approximate — not an official figure. It moves continuously as people are added, move, or are released from the requirement. Treat it as scale; for a specific person, run a search.
03The rate divides that count by the ZIP’s residents (ACS 2019-2023 5-year estimate), per 10,000. A small ZIP with a prison, a hospital or a shelter can carry a high rate on a handful of people, and a rate is shown only where the count is large enough to mean something. The Pennsylvania average is about 19.5 per 10,000.
04A ZIP is listed when we index at least 5 registrants with it and it has at least 1,000 residents. A Pennsylvania ZIP that is not on this page is not a ZIP with nobody registered — enter an address in it and the count near that address is free.

Pennsylvania sex offenders by ZIP code FAQ. Quick answers before you open a ZIP.

Which Pennsylvania ZIP code has the most registered sex offenders?

Of the 798 Pennsylvania ZIP codes we publish, 19426 (Trappe) has the most registrants we index, about 425 (Montgomery County). By rate, 17103 (Harrisburg) is highest at about 118.2 per 10,000 residents. Large ZIPs usually have large counts, so the per-10,000 figure beside each ZIP is the fairer comparison.

How many Pennsylvania ZIP codes are on this sex offender list?

798, holding about 21,770 registrants we index between them, across 65 counties. A ZIP is listed when we index at least 5 registrants with that ZIP and it has at least 1,000 residents. A ZIP that is not listed is not a ZIP with nobody registered — search from an address in it for the current picture.

Is there an official Pennsylvania sex offender list by ZIP code?

Registries are kept by the state, not by ZIP code, so Pennsylvania publishes no official list by ZIP. This page counts the registrants we index whose address carries each ZIP, as of October 2026, rounded and approximate. A search from any Pennsylvania address shows who is registered around it, each record linking to its official registry entry.

To see everyone near it — names, photographs, offenses and exact addresses — it is paid once, or Family Watch for 3 addresses with an email when someone moves in or out. Checking a person instead?
