How to read my pin in Cook County?

Modified on Wed, 22 Aug, 2018 at 11:28 AM

The PIN is a 14-digit number composed of a 10-digit base that is modified for condominiums and leaseholds by adding a four-digit unit suffix. The basic PIN structure is:

AA-SS-BBB-PPP-UUUU

AA is the AREA number (sequential township)

SS is the SUBAREA number (section)

BBB is the BLOCK number

PPP is the PARCEL number

UUUU is the UNIT number for condominiums and leaseholds (zeros in this portion of the PIN indicate non-condo and non-leasehold PINs)
