eCFR

eCFR is the Acronym for Electronic Code of Federal Regulations

The Electronic Code of Federal Regulations is the continuously updated web edition of the federal agencies’ rules. It shows the text of each title, and it incorporates amendments on a rolling basis rather than waiting for a once-a-year printed volume.

The underlying set of rules is the Code of Federal Regulations (CFR). The electronic edition is a way of reading that code. It is not a separate body of law.

How the Web Edition Differs in Practice

  • Rolling updates. An amendment can appear in the web text within days, ahead of the next annual print.
  • The same titles. The title and part numbers match the codified rules.
  • Not the statute book. It contains agency rules, not the acts those rules implement.
