Winnebago County is located in the state of Illinois. The county was formed out of Jo Daviess County and LaSalle County on January 16, 1836, and named after the Winnebago Tribe of American Indians. Rockford is the largest city in the county and also the county seat. According to the U.S. Census Bureau, the county has a population of approximately 295,266 people, making it the 7th most populous county in Illinois behind Cook County and its 5 surrounding collar counties. It covers a total area of 519 square miles, of which 5.9 square miles is water and 513 square miles is land.  Winnebago County borders the following counties: Rock County, Wisconsin, to the north; Boone County to the east; DeKalb County to the southeast; Ogle County to the south; Stephenson County to the west; and Green County, Wisconsin, to the northwest.

The Winnebago County Clerk is an elected official who serves as the administrative arm of the Winnebago County Government. The county clerk is responsible for a number of responsibilities that are divided into four categories:

  • Vital records and licenses
  • Elections
  • Tax extension and redemption
  • County board record maintenance

Copies of vital records (birth records, marriage records, and death records) maintained by the clerk’s office can be accessed by doing a background check online. Your online request will be processed through an independent company, VitalChek, that the County Clerk has partnered with to provide the public with this service. When using VitalChek, you will be charged an additional fee by the company, and all major credit cards are accepted, including Visa, MasterCard, Discover, or American Express.

The other way to obtain copies of vital records is by visiting the clerk’s office in person. You will be required to submit a written request with details of the records you want to obtain. Below is the physical address of the Winnebago County Clerk’s office:
