Legislation, Regulations, and Guidance

The Code of Federal Regulations (CFR) is the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation. Each volume of the CFR is updated once each calendar year and is issued on a quarterly basis. The Electronic Code of Federal Regulations (eCFR) is not an official legal edition of the CFR, but is a continuously updated online version of the CFR and provides enhanced features that are not part of the published CFR.
