The AOC Guide to Oregon Counties includes key contact information for Oregon’s 36 counties.

Depending on the county, this may include: county commissioner, county judge, assessor, administrator, county clerk, county counsel, district attorney, justice of the peace, sheriff, county surveyor, and/or county treasurer. In addition, a county department directory for each county is included.

The print version of the directory is updated every other year, while the online version is kept up-to-date as new information is received.
