Who to Call at Rock County Jail (Janesville): operations, admin, and records contacts

Need to reach Rock County Jail right away? Call the 24/7 operations line: 608-757-8000. Someone's always there - day or night - for urgent custody questions or on-site issues.

For non-urgent questions - paperwork, follow-ups, general administrative stuff - call during office hours: Monday through Friday, 7:00 am to 3:00 pm. You'll get better results than trying the operations line for routine matters.

Need to escalate an issue? Captain Nicholas Brown serves as Assistant Jail Administrator. His direct line is 608-757-7907. Try this when you've already called the main numbers and need to push an administrative concern higher.

Sending documents by fax? The administrative fax number is 608-757-7997. For anything time-sensitive, keep a copy of what you sent along with the fax confirmation page.

Questions about inmate or jail records? Call 608-757-7958 directly. Starting here saves you from getting bounced between departments.

For written requests or open records submissions, send mail to the Rock County Sheriff's Office at 200 E. US Highway 14, Janesville, WI 53545.
