Opportunity Zones use census tracts
A ZIP code can include multiple census tracts, and a census tract can cross parts of more than one ZIP code. That is why ZIP research should lead to census tract confirmation.
ZIP-based starting point
Opportunity Zone Map by ZIP Code
ZIP codes can narrow a research area, but Opportunity Zone status is based on census tracts. Use this page as a starting point, then confirm tract status with official sources.
Research path
Next steps for ZIP
- Use the ZIP code to narrow the city or local search area.
- Use the Census Geocoder or another official source path to identify the census tract for a specific address.
- Match that census tract against CDFI, HUD, Treasury, IRS, or state source materials.
- Confirm any tax, legal, or investment question with a qualified professional.
Why ZIP code is only a starting point
