Code of Federal Regulations

This list attempts to group titles by the most relevant cabinet departments and equivalent federal departments, as called out in the structure of each title. 

Not all titles map to only one department or agency. Follow these directions on the eCFR website to search the eCFR for references to a specific agency. You can also click the "Details" option on the left sidebar while reading eCFR content to see the agency responsible for that content.

Information about the administration of all departments can be found in Title 5. 
Policies regarding government acquisitions for all departments can be found in Title 48.
