Who to Call at Oconto County Jail: Key Phone Numbers and County Contacts

Not sure where to start? The main Oconto County government line can help route you. The county mailing address is 301 Washington Street, Oconto, WI 54153, and the main phone number is 920-834-6800. Use this for general county questions or when you need to be pointed toward the right department. For day-to-day jail operations, there's a more direct line (see below).

For jail-specific questions, call the Jail Administrator directly. Oconto County Jail is overseen by Jail Administrator Carol Kopp. The number for jail inquiries is 920-834-6917.

Knowing how the jail is staffed helps explain why you might talk to different people depending on your question. Oconto County Jail has 27 staff members: 1 Jail Administrator, 1 Jail Lieutenant, 4 Sergeants, 4 Corporals, 1 Jail Receptionist, and 17 Correctional Officers. The administrator oversees the facility. Supervisory staff (the lieutenant, sergeants, and corporals) manage daily operations. The receptionist handles front-line administrative calls. Correctional officers work directly in the housing areas.

Need a direct, authoritative answer about the jail? Start with Jail Administrator Carol Kopp at 920-834-6917. This is your best bet for policy questions, unresolved issues, or anything beyond a routine front-desk inquiry. If you reach other jail staff, that can still be helpful. The receptionist can often point you to the right person or explain what information the jail shares over the phone. Supervisory staff handle daily operations, so they're typically involved when something needs follow-up or a supervisor's decision. Correctional officers focus on housing-unit duties and safety, so they're not the right contact for administrative requests, but they can pass along a message through proper channels. For questions that go beyond the jail, or if you need help finding the right county office, call the main Oconto County number at 920-834-6800.
