How to verify whether any U.S. street address sits inside one of the 8,764 U.S. Treasury / IRS Designated Qualified Opportunity Zone (QOZ) Census Tracts under 26 U.S.C. § 1400Z-2.
How Qualified Opportunity Zone (QOZ) Boundaries Work
Created under the Tax Cuts and Jobs Act (26 U.S.C. § 1400Z-2) and certified by the U.S. Treasury CDFI Fund, 8,764 Census Tracts across all 50 states, DC, and U.S. territories are designated as Qualified Opportunity Zones. Because QOZ boundaries follow 11-digit Census Tract polygons rather than ZIP codes, two buildings on opposite sides of the same street can have different QOZ tax status.
