US Congressional District Codes

IMLS-provided data references congressional districts using a 3- or 4-digit code consisting of the state's FIPS ID followed by the number of the district (or "00" in the case of at-large representatives of smaller states). This spreadsheet correlates the IMLS district code to a human-readable code in the format of ST-XX, e.g., "IL-18" for the Illinois 18th district or "AK-00" for Alaska. It can be used as a lookup table for other IMLS data products.

This version is based on the 116th Congress based on information found at
