FORHP released a couple of excel files that contain information about FIPS and ZCTAs. For people with large amounts of data where they want to see if a certain zip code is eligible for a person would have to do a search and find on all the zip codes.
Here is a spreadsheet that allows you to paste a bunch of zip codes and then return:
- % ZIP population in the County
- FIPS
- CBSADesig.
- If eligible
The data is based from a download that took place on 9/15/2020 from: https://www.hrsa.gov/rural-health/about-us/definition/datafiles.html
Hope this works out for you if you ever need it. Take a look at my city/state zip code converter.
