Living on the Kentucky side?

ZIP codes are 2020 Census ZIP Code Tabulation Areas, which closely approximate USPS ZIP codes. We list ZIPs that make up a substantial share of each community, so edge ZIPs that barely touch a town are left out, and some ZIPs span two towns.6 Not on the list? Send the form anyway, and we'll tell you if we can help.
Please note: Ohio requires a license to give professional or expert advice on radon testing, exposure or mitigation. This page is general information summarized from public agencies, not professional advice. For advice about your home, talk with an ODH-licensed professional.
