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.
Please note, you must provide either street + ZIP or street + city + state in order to receive Census results back. We do not provide this data for ZIP codes or city/state pairs. (If your data contains locations without street addresses, you will not be charged for the data append for those locations.)
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 with, for example, HMDA or CRA.
We always return data for the most recent Census year. Currently, the most recent year is the 2020 Census year. Historic Census data back to 2010 is available through the API or by using the drop-down menu in the spreadsheet upload tool (example below).
