What are PINs?

Cook County Assessor's Property Search

A PIN describes a property, often in the form of a discrete parcel of a land, but frequently as a condo in a shared piece of land. Most of the PINs represent taxable properties; the remainder represent exempt properties, or 'retired' PINs that resulted from splitting or joining PINned properties.

Notes

[1] The FOIA request to the Cook County Treasurer's office was considered voluminous and would cost money; the original response said that 50 PINs would fit on a page, making for over 36,000 pages. We inquired about the possibility of providing it in an Excel spreadsheet. The final request was returned in 11 Excel documents after transmitting $100. It was noted in the FOIA request that it was for a commercial use – this extends the time the office has to respond from 5 days to 25 days.
