What is a P.I.N.?

A Property Index Number (PIN) is a unique 14-digit number identifying your property. It's used for the legal description, assessed value, tax bills, and appeals. Find it on your tax bill, assessment notice, or county property records. Using the correct PIN is essential—errors can delay or invalidate an appeal.
