How to read Connecticut sex offender counts by ZIP code. Four things to know before comparing two Connecticut 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 Connecticut 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 Connecticut average is about 16.3 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 Connecticut 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.

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

Which Connecticut ZIP code has the most registered sex offenders?

Of the 152 Connecticut ZIP codes we publish, 06511 (New Haven) has the most registrants we index, about 239 (New Haven County). By rate, 06710 (Waterbury) is highest at about 71.4 per 10,000 residents. Large ZIPs usually have large counts, so the per-10,000 figure beside each ZIP is the fairer comparison.

152, holding about 5,239 registrants we index between them, across 8 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 Connecticut sex offender list by ZIP code?

Registries are kept by the state, not by ZIP code, so Connecticut 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 Connecticut address shows who is registered around it, each record linking to its official registry entry.
