  • The CFR is divided into 50 titles or broad subject areas.
  • Each title is divided into chapters (I, II, III, etc.) which usually bear the name of the issuing agency.
  • Chapters are divided into parts (1, 2, 3, etc.) covering a single subject or agency function.
  • Subparts (A, B, C, etc.) group related sections within a part.
  • Parts are divided into sections, the basic unit of the CFR.
    Section numbers include the symbol §, the number of the part, a period, and the section number.
    For example, §25.3 is the third section in part 25.
