U.S. Census Identifiers (FIPS/GeoID)

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 with, for example, HMDA or CRA.

Census year
State FIPS
County FIPS
Place Name
Place FIPS
Tract code
Block code
Block group
Metro/Micro Statistical Area (MSA)
Combined Statistical Area (CSA)
Metropolitan Division [note: Only a few metropolitan statistical areas contain metropolitan divisions, so this will only be returned if relevant.]
County Subdivision: Minor Civil Division (MCD) / Census County Division (CCD)

We also automatically concatenate Census geography IDs into commonly-used longer FIPS codes (GeoIDs):

For API and spreadsheet uploads: Full FIPS (block) to 15 digits (concatenation of State, County, Place, Tract and Block)
For spreadsheet uploads only: Full FIPS (tract) to 11 digits (concatenation of State, County, Place, and Tract)

You can download an example of the results when you add Census blocks, tracts, and FIPS codes to a list of addresses here.

We always return data for the most recent Census year. Currently, the most recent year is the 2023 Census year. Historic Census data back to 2000 is available through the API or by using the drop-down menu in the spreadsheet upload tool (example below).

Vintage Census Years

It is also possible to request boundary data for a vintage Census year. The following Census years are supported:

2023 Census
2022 Census
2021 Census
2020 Census
2019 Census
2018 Census
2017 Census
2016 Census
2015 Census
2014 Census
2013 Census
2012 Census
2011 Census
2010 Census
2000 Census (only County, Place, Tract and Block FIPS codes)

GeoIDs and FIPS

Some federal datasets report data at the GeoID level. GeoIDs are concatenations of various levels of FIPS codes, depending on the dataset. GeoIDs, or FIPS codes, can be up to 40 digits. The more digits there are, the more granular of a measurement it is.

Geocodio returns FIPS codes, which can be matched to GeoIDs.

Let's use 580 Meyers St, Kettle Falls, WA 99141 as an example:

If your dataset gives a GeoID of this length...	...it translates to this combination of FIPS codes	Example GeoID	Geocodio Result Name
2 digits	State	53	State FIPS
5 digits	State + County	53065	County FIPS
11 digits	State + County + Tract	53065950101	concatenate County FIPS + Tract Code; pre-concatenated for spreadsheet uploads as "Full FIPS (tract)"
12 digits	State + County + Tract + Block Group	530659501012	concatenate County FIPS + Tract Code + Block Group
15 digits	State + County + Tract + Block	530659501012022	concatenate County FIPS + Tract Code + Block Code; pre-concatenated for spreadsheet uploads as "Full FIPS (block)"
