The United States Code is the official codification of the general and permanent federal statutes of the United States. It contains 53 titles. The main edition is published every six years by the Office of the Law Revision Counsel of the House of Representatives, and cumulative supplements are published annually. The official version of these laws appears in the United States Statutes at Large, a chronological, uncodified compilation.

In law, codification is the process of collecting and restating the law of a jurisdiction in certain areas, usually by subject, forming a legal code, i.e. a codex (book) of law.
