Registered Agents for Insurance Companies

Last Updated: May 12, 2017

Authorized insurers are required to designate a Registered Agent at a Wisconsin address for service of process concerning a Wisconsin court case or a proceeding before a Wisconsin state agency (s. 601.715, Wis. Stat.). An insurer may change its Registered Agent in accordance with s. 601.715 (2), Wis. Stat., by filing a new Designation of Registered Agent (Fillable) form. The Wisconsin Office of the Commissioner of Insurance (OCI) maintains a file of all designated Registered Agents for insurance companies licensed in Wisconsin but does not maintain telephone numbers for Registered Agents.

Registered Agent information on file with OCI is located at State Based Systems

  1. Under Jurisdiction select "Wisconsin" from the dropdown list. Under Search Type select "Company" from the dropdown list.
  2. In the search field under Company Name type the name or partial name of the company for which you are seeking registered agent information. Press the Enter key (ignore the green search button).
  3. Click on the company name.
  4. Scroll to the bottom of the page until you see the "Contact" information header and locate the "Registered Agent for Service of Process" section. If there is no listing in the "Name" field, the process should be served at the listed business address without listing an individual's name.

If you cannot find the company, the insurer might have changed its name, merged with another insurer, or be using a group name rather than the name of the actual insurer. You can obtain further information by contacting OCI at 608-266-0090 or lynn.welsh@wisconsin.gov.

If you are unable to complete service on a Registered Agent after reasonable diligence, or if a company does not have a designated Registered Agent, you may accomplish substituted service on OCI by following the procedures in s. 601.72, Wis. Stat. Please note the case must involve a Wisconsin court or a proceeding before a Wisconsin state agency. Mail the following to OCI at P.O. Box 7873, Madison WI 53707-7873:

  1. A cover letter naming the documents, the insurance company, and the address you wish to serve.
  2. Two identical authenticated copies of the documents to be served (e.g., summons, complaint, notice, pleadings, orders).
  3. A check for $10.00 payable to the Office of the Commissioner of Insurance for each service.
  4. A self-addressed, stamped envelope to return a copy of the certificate of process to you.
