About Your Property Index Number (PIN)

PIN stands for Property Index Number, and knowing your PIN is important to protecting your money and the real estate that you own.  Property taxes may be paid by current or past owners, a title company, a mortgage company, a lease-holder, a co-op, a tax buyer or a combination of parties.  Unlike an account that is assigned to an individual or business, a PIN is assigned to the property.  This important information is intended to help you understand the importance of your PIN.

What is a PIN?
PIN stands for Property Index Number.  This unique 14 or 16-digit number is assigned to the legal description for each piece of real estate in Will County, including vacant lots, parking spaces and condominium common areas.  The PIN is used for assessments, tax rate calculations and tax collections.

Why is the PIN important?
A PIN is to a property what a Social Security Number is to a person.  If you have your name placed on a tax bill for the wrong PIN and pay that wrong PIN, the taxes on the PIN you actually own are still delinquent.  For that reason, the PIN is the key to making correct payments.

How can I be sure to pay on the right PIN?
Match the PIN on the tax bill to the PIN on your Deed.  This is very important when you: (1) pay off a mortgage and take over tax payments, or (2) refinance with a new company.  An attorney who handles your property matters, or your township assessor, may be able to help verify a PIN.  If your Deed contains only a legal description, the Mapping Department in the Supervisor of Assessments Office, which assigns PINs, can find the PIN.

Can a PIN ever change?
Yes.  When a property is divided after being altered, each new parcel gains a new legal description and, thus, a new PIN.  Taxpayers should make sure they have the proper PIN when paying taxes on a new house, townhouse, loft, condo unit and, in some cases, parking spaces.

If my taxes are paid from my escrow, do I need to be aware of my PIN?
Absolutely.  You need your PIN to verify that your mortgage company is making payment on time, in full and on the right real estate.  Also, if you and other owners share a PIN, as happens with a newly developed property, you need to contact our office for information on submitting payment by legal description.  “Paying By Legal” helps you avoid underpaying, overpaying or having your taxes sold if others who share your PIN are delinquent.

Do I need my PIN for any other reasons?
Yes.  You need the PIN to request a duplicate tax bill from the Treasurer’s Office or to call with any questions you may have about payments, assessments, appeals, exemptions and tax rates.  It is very important to know your PIN and, if you have more than one property, the property address each PIN applies to, when calling the Treasurer’s Office during tax collection time.
