I have a reference request I'm having difficulty researching: the patron needs to locate and verify the zip codes of both Federal HUB and Empowerment Zones.

 

I checked the U.S. Small Business Administration's HUBZone and the City of Detroit's Open Data Portal.  However, I have not been able to locate and identify this information.

 

If you have any ideas, tips, or suggestions, please let me know.
