Federal Laws and Regulations

Code of Federal Regulations (CFR)

Spell out Code of Federal Regulations on first use, including the title of the regulation and the citation.

Example: In the United States, the Certification of Opioid Treatment Programs, 42 Code of Federal Regulations (CFR) 8 governs the treatment of opioid dependence with opioid medications.

If you link to this citation again on the page, you’d use 42 CFR 8.

Link to the Electronic Code of Federal Regulations (eCFR). Do not link to a PDF or another website’s posting of CFR text.

Public laws

Format citations: “Title” (PL ###-###, date).

Example: “Children’s Health Act of 2000” (PL106-310, 17 October 2000).

Note: On pages where this would overly complicate the content, such as timelines or a list of laws, you can limit the citation to just the title of the regulation or law. Consistency among citations on a single page is important.
