Captcha verification:
To continue to search for PIN : 19232130260000 , please enter the text in the box to the right to verify you are human.

We have added the “captcha” (scrambled letter) function to our website in order to authenticate human users. This will add a step to each PIN and appeal search similar to that which appears when one wants to obtain tax bill information from the Treasurer and file on-line with the Board of Review. Please be advised that these recent changes became necessary after a robotic attempt to infiltrate our data made the website nearly inoperable.

Although this added step may present an inconvenience, it will:

  • Safeguard the integrity of our data
  • Protect your access and ability to rely upon our data
  • Permit access to necessary forms in a timely manner
  • Eliminate impediments to performing searches
  • Ensure that those who contracted for our subscription service receive the benefit of that service
  • Guarantee that unauthorized users will not improperly obtain office data for commercial purposes
  • Reflect best practices employed by many governmental agencies and private ventures which value the security of their data
  • Mirror protections already in place within other agencies of Cook County involving the property tax system such as the Treasurer and the Board of Review
  • Return processing back to a few seconds from a full five minutes at the height of the problem
