You can upload a spreadsheet of addresses or coordinates to Geocodio and add Census identifier information such as Census blocks, tracts, and FIPS codes. Simply select "Census" in Step 3 of the upload process, or use the census field in the API.

This information can be helpful to connect government datasets, such as to CMS or American Community Survey data, as well as for reporting and compliance needs.
