Welcome to the online home of the County Auditors' Association of Ohio - CAAO.

Please take our tour of a County Auditor's office to see the many responsibilities our County Auditors perform in the spirit of public service.

We also direct your attention to the AUDITORS' DIRECTORY, and online database listing Auditor information for each of Ohio's 88 counties.

You also will find links to each of Ohio's GIS mapping websites, managed by the County Auditors.

Support to our Association is provided, in part, by our Business Partners. You'll find them listed in our Business Partner directory page.
