Winnebago County, IL parcel owner data
9,179 parcels with the owner of record. 9,179 carry an owner mailing address (100%), and 3,782 of those are absentee — the list investors mail first. Browsing is free and unlimited on the map; one credit turns any owner into a verified phone and email, and only if one comes back.
What a county file actually lands at. 232 of these rows (3%) are owned by a government body, a school or water district, a church, a cemetery or an HOA, and every list pull strips them — so a Winnebago County file arrives at about 8,947 mailable rows, not 9,179. That is the number to price against.

What Winnebago County publishes
A county is only as useful as the columns it fills in. This is measured on the rows themselves, not promised: how many of this county's 9,179 parcels carry each field.
| Field | Rows | Share | Coverage | Status |
|---|---|---|---|---|
| Parcel numberThe county's own APN, exactly as published. | 9,179 | 100% | Complete | |
| Latitude / longitudeParcel centroid. This is what puts the row on the map. | 9,179 | 100% | Complete | |
| Owner of recordName as the assessor publishes it, second owner kept where there is one. | 9,179 | 100% | Complete | |
| Property addressStreet address of the parcel itself. | 9,171 | 100% | Complete | |
| Property ZIPNeeded for a ZIP-scoped pull. | 9,179 | 100% | Complete | |
| Owner mailing addressOne line, as published. This is what a mail piece is addressed to. | 9,179 | 100% | Complete | |
| Mailing city / state as separate columnsSome counties publish the mailing address split into fields; most publish one line. Absentee and out-of-state are derived either way. | 0 | 0% | Not published | |
| AcreageDeeded acres. Absent in Florida and Colorado counties. | 9,179 | 100% | Complete | |
| Assessed land valueLand only. There is no improvement or total value, so equity cannot be estimated. | 0 | 0% | Not published | |
| Land use codeFree text from the county. Missing entirely in Texas and Florida, so a vacant-land filter matches nothing there. | 0 | 0% | Not published |
Read this before you filter. Mailing city / state as separate columns, Assessed land value, Land use code are under 40% populated in this county. A filter on them silently drops every row that has no value, so a range filter here will return far fewer records than the parcel count suggests.
Not in the record — for any county
- Sale date, sale price, transfer history
- Mortgage, lien, foreclosure or tax-delinquent status
- Equity (there is no total value to subtract from)
- Year built, square footage, beds and baths
- Flood, wetlands, landlocked or road-frontage flags
- Owner phone and email — those are traced on request, never stored on the parcel
Twelve real rows
Drawn deterministically by a hash of each row's own key, so these are the same twelve rows on every render and they spread across the county rather than down one street. Government, school, church and HOA owners are excluded, the way they are in a pull.

What you can do with Winnebago County owner data
Pull every absentee owner in a ZIP and export the mailing addresses for a direct-mail campaign. Draw a box around a subdivision on the map and skip-trace the whole block in one job. Look up who owns the lot next to a listing, then call them with a scored number instead of sending a letter that gets thrown away.
Where the data comes from
Parcel boundaries, owner of record and mailing addresses are public records maintained by the county assessor or GIS office. Quarry pulls them from the county's own published services and refreshes on the county's cycle; the counts on this page were measured 2026-09-09. Phone and email come from the skip-trace engine, cross-checked across sources and scored, and you are only charged when a contact is found.
