ecfrgov

ecfr.gov hosts the Electronic Code of Federal Regulations (eCFR), an online, continuously updated version of the Code of Federal Regulations. The CFR is the codification of general and permanent rules issued by U.S. federal agencies and published in the Federal Register. The eCFR is maintained by the National Archives and Records Administration (NARA) in cooperation with the Office of the Federal Register and the Federal Register staff. It provides current regulatory text in a searchable, navigable form and is organized by title, part, and section.

Content and features: The eCFR presents the current text of the CFR and offers browsing by Title, Part, and Section, as well as a search function. Users can view content in HTML and download PDFs; it also includes editorial notes and links to related Federal Register notices where relevant. The resource is designed to reflect changes as they are codified and integrated into the CFR.

Access and status: The eCFR is a free public reference tool intended to facilitate up-to-date access to federal regulations. It is not the official final edition of the CFR for legal purposes; the official codification remains the CFR as published in the Federal Register and in the formal printed or GovInfo editions. The eCFR complements these sources by providing a current, easily searchable online version.
