Search Winnebago County Phone Directory
Winnebago County Phone Directory searches work best when you know which office holds the file. In Oshkosh, the county courthouse, the clerk of courts, the Register of Deeds, and the sheriff each handle a different record path. That split saves time once you see it. Start with the county portal, then move to the court office, the deeds office, or the sheriff page that matches your need. If you already have a case number, parcel number, or report number, the search gets much faster. A short call or the right page can keep you from chasing the wrong desk.
Winnebago County Phone Directory Overview
Winnebago County Phone Directory Basics
Winnebago County is centered in Oshkosh, and that matters when you are trying to find the right desk. The county courthouse at 415 Jackson Street is the anchor point, but it is not the only place to look. Court files, deed records, and sheriff records live in different offices. The county portal at co.winnebago.wi.us is the best first stop when you only know the topic and not the office.
The county portal gives you the main path into public records. From there, you can move into the clerk, the deeds office, or the sheriff page, depending on what you need. That order keeps the search local and cuts down on dead ends. It also helps when a record is split between offices or when one office can point you to another. Winnebago County is busy enough that a broad search usually needs a second step.
Use the county portal first when you need a phone number, an office address, or a way to confirm which desk holds the file. Once you know the holder, the rest of the request is easier to shape.
Winnebago County Phone Directory for Court Records
The Winnebago County Clerk of Courts at co.winnebago.wi.us/clerk-courts keeps the county's court records at 415 Jackson Street on the first floor in Oshkosh. The main phone number is 920-236-4848, the fax number is 920-424-7780, and the Circuit Court Contact Line is 920-236-4808. Office hours are Monday through Friday, 8:00 AM to 4:30 PM. That office handles records for civil, criminal, family, probate, and traffic matters.
WCCA is the fast public path for basic case details. It shows party names, filing dates, charge or case information, and scheduled court events. When you need more than a summary, the clerk's office still controls the file. That is why a county phone directory page should keep both the office number and the web tool in the same place. The records copy page at co.winnebago.wi.us/clerk-courts/recordscopy-requests gives the county's request route when you need a copy or a prepayment step.
Copy fees are listed at $1.25 per page for plain copies, $5 for certification, $5 for search or off-site files, $10 for DAR recording, and $5 for CD or DVD copies. Pre-payment is required. The office also uses AllPaid with pay location code 1547, and the payment line is 888-604-7888. Those details matter when a case turns from a quick lookup into a copy request.
- Full party name or case caption
- Case number, if you have it
- Approximate filing year
- Record type such as civil, family, or probate
- Contact details for follow-up questions
Note: WCCA is useful for a quick case check, but the courthouse is still the place to go when you need a copy or the full file.
Winnebago County Records and Deeds
The Winnebago County Register of Deeds is at 112 Otter Avenue, Room 108, Oshkosh, WI 54901. The office phone is 920-232-3390, and the email listed in the research is rod@winnebagocountywi.gov. It maintains birth and death records, land documents, and other official records. If you need a deed, a mortgage image, or a certified vital copy, this office is a better fit than the courthouse.
The record path is simple enough once you know it. The deeds office handles the document trail, while the clerk handles court files. That split matters because a phone directory page should not force you to guess which office owns the record. The county portal and the Register of Deeds page at co.winnebago.wi.us/register-deeds are the cleanest starting points when you need a file, not just a contact name.
When you are checking a property trail, begin with the deed office and add the parcel details if you have them. When you are checking a vital record, ask for the certified copy path first. That keeps the request narrow and makes the office work easier.
Winnebago County Sheriff Files
The Winnebago County Sheriff's Office is at 4311 Jackson Street, Oshkosh, WI 54901. The phone number is 920-236-7300, and the records email in the research is sheriffrecords@winnebagocountywi.gov. That office keeps crash file logs, law checks, and photos tied to sheriff work. If the matter started outside city limits or involved county jail activity, the sheriff page is a useful place to start.
Requests go faster when they stay specific. Give the date, the place, the name, or the report number if you have it. That lets staff find the right report faster and cut the back-and-forth. The sheriff office is also one of the county spots where access limits may apply. Active investigations, safety concerns, or sensitive details can narrow what gets released. That is normal under public-records practice.
The sheriff page at co.winnebago.wi.us/sheriff gives you the county's own route for records, and the county portal can point you to related departments if the file lands somewhere else. If you need a court follow-up after a law-enforcement event, move from the sheriff page to the clerk of courts or WCCA. That keeps the trail local and easy to track.
Winnebago County Phone Directory Public Records Rules
Wisconsin public records law shapes how Winnebago County answers requests. Wis. Stat. § 19.31 sets the policy that the public should get the greatest possible information about government work. Wis. Stat. § 19.35 gives requesters the right to inspect and copy records. Wis. Stat. § 19.36 explains what can be withheld or redacted. That framework matters when a county office gives you part of a file but not all of it.
The county and state pages work well together. For court status, wicourts.gov and WCCA are the best statewide tools. For record checks beyond the county, the Wisconsin Vital Records office at dhs.wisconsin.gov/vitalrecords/index.htm is the official state source for certified vital record help when the county office tells you to go there. Those state pages are useful, but they fit best after you know the local office.
The safest path is simple. Start with Winnebago County, use the office that holds the file, and then step up to the state only if the county desk points you there. That keeps the request local and keeps the work clean.
Winnebago County Phone Directory Images
The county portal at co.winnebago.wi.us is the broadest starting point, and the image below shows that main entry page.

Use that page when you want the county's own contact trail before you choose a records desk.
From there, you can branch into the clerk, the deeds office, or the sheriff without losing the thread. That makes the portal a good visual anchor for the rest of the county record search.
Note: The county portal is broad, but the record office matters more when you need a copy, a certified document, or a file held in storage.
Winnebago County Phone Directory Tips
The best Winnebago County search is the one that lands in the right office on the first pass. If you are looking for court records, start with WCCA and then move to the clerk. If you are looking for property records, start with the Register of Deeds. If you are looking for a sheriff report, start with the records line and keep the request specific. That simple order matters more than broad searching.
When the office has to do the hunting, the wait grows. When you bring a name, a number, or a date, the search moves faster. That is why Winnebago County pages like this one should stay practical. They should tell you which desk owns the file and which link gets you there. A clear request also helps the office decide whether a copy can be released as plain, certified, or redacted.
State fallback is still useful, but it should come after the county path. Use the Wisconsin Courts site, the public records statutes, and the Vital Records office when the local page points you there. That keeps the search local without losing the broader picture.
