What is the legal status of this publication?

The Electronic Code of Federal Regulations (eCFR) is a web version of the Code of Federal Regulations (CFR) that we update daily to better reflect its current status. The eCFR is an editorial compilation of CFR material and amendments published in the daily Federal Register.

The Administrative Committee of the Federal Register (ACFR) has authorized the National Archives and Records Administration’s Office of the Federal Register (OFR) and the Government Publishing Office (GPO) to develop and maintain the eCFR as an informational resource. The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on the eCFR with the objective of eventually establishing the eCFR as a publication officially recognized by the ACFR.

While we try to ensure that the material on the eCFR is accurate, those relying on it for legal research should verify their results against the most current official edition of the CFR, the daily Federal Register, and the List of CFR Sections Affected (LSA), available online at www.federalregister.gov and www.govinfo.gov. For complete information about, and access to, our official publications and services, go to the OFR’s website on www.archives.gov.
