2010 Census Blocks by State

Below are links to lists of the 15-digit census block FIPS codes for each U.S. state/territory in two formats: (1) a CSV file listing all of the census blocks in a state, or (2) an Excel file with a worksheet for each county in the state that lists the census blocks in that county. The block codes are based on the 2010 Census. All individual files are zipped (.zip).

In addition to the 15-digit block FIPS code, each row in the downloadable tables includes the state, county, and tract FIPS code, as well as the county name, associated with each census block.
