Add Census FIPS Codes, Blocks, and Tracts to a Spreadsheet of Addresses

Are you working with addresses that you need to connect to government datasets? Most government data is published at the FIPS code level. To connect your data, you'll need to find the FIPS codes, or perhaps the Census Tracts or Blocks, for the addresses. Geocodio can help you convert the data quickly.

1. Gather the addresses or coordinates you want to find the FIPS codes, Census blocks, and Census tracts for

First you will need to collect all of the addresses or coordinates you want to convert to FIPS codes, blocks, and tracts. You can put them in a spreadsheet, or integrate this data into an application via our API. See how to format your spreadsheet here, or get an API key here.

2. Upload the spreadsheet to Geocodio to add FIPS codes, Census blocks, and Census tracts

If your addresses or coordinates are in a spreadsheet, you can upload it to Geocodio. In Step 3 of the Upload process, you'll be given the option to add additional data:

For the US, you'll want to select Census Identifiers. When you click this box, we'll return several different Census geographies for the address or coordinate, including 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), and Metropolitan Division. You can see a sample output here.

For Canada, you'll want to select Canadian Census Identifiers. This will add Statistics Canada geographic identifiers such as divisions, economic regions, and tract IDs. See the full list here.

Alternatively, use our API to get the FIPS codes, Census blocks, and Census tracts

Using our API, you'll just need to add the &fields=census for the US and &fields=statcan for Canada parameter to your requests . See more in our documentation here.

VIDEO: How to Add FIPS Codes, Census Blocks, and Census Tracts to a Spreadsheet of Addresses

This video shows you how to add Census FIPS codes to a spreadsheet of addresses. Note that this will also work with coordinates as well.

First we're going to start out with a spreadsheet of addresses. We have them split into separate columns with headers for address, city, state, and zip code, and note that the addresses don't have to be complete. Geocodio will complete the addresses and add the county as well. And to see how you can format your spreadsheet, you can go to, click on Help, click on Guides, and then go to Spreadsheet Formatting ( And there you can download sample files and you can also download an example geocoded file. In addition, since we're working with FIPS codes here, you can go to Census ( and you can download an example geocoded result with Census FIPS codes, MSAs/CSAs, blocks, and tracts added.

Once our spreadsheet is formatted, we can go to and upload the file. We can either drop it or select it, or we can also paste in addresses or coordinates if we for example have a larger file and only need to work with a small segment of it.

So we're going to drag in our file. Then we will confirm all of the headers that are mapping over to the columns. We can see a preview of the addresses here. We can also see a preview of them on the map. Then in Step 3 we can add on other data, such as timezones, ZIP+4, and Census data. To add FIPS codes, we will click US Census Identifiers. This will add on the data to our spreadsheet, it will not delete any data on the spreadsheet. We will click continue.

We'll see an estimate below, so our list had 50 rows of addresses, plus one data append, so that will count as 100 lookups. And the first 2,500 lookups per day are free, so this file will not cost us anything, and the processing time is estimated to be less than a minute. Press Start.

Now we do not have to stay on this page and wait for it to process, you will receive an email when the file is done processing. However, this is a very short list, so it is already done, so we can now download the spreadsheet.

And here we can see our spreadsheet with the FIPS codes, Census tracts, Census blocks, and the Metro/Micropolitan Statistical Areas. And note that it's quite common for Excel to do this where it will truncate the full FIPS, but as you can see in the formula bar, the full FIPS code is indeed there.
