About eRegulations

ATF uses the eRegulations platform to make regulations easier to read and navigate.

Regulation data is copied from the Office of the Federal Register website and the GPO FDSYS system and should not be considered authoritative, as those sources are not official legal editions of the Code of Federal Regulations.

eRegulations clarifies regulations by bringing related information and regulatory history to the forefront. It is a work in progress and a public domain work of the United States Government.

Below are details on some eRegulations features and how to use them.



eRegulations is an open source project. Visit the project repository to learn more and contribute.

The regulation timeline shows recent revisions of the regulation organized by latest effective date.

  1. The date picker allows users to find what revision was effective on a specific date.
  2. Federal Register notice(s) associated with a revision are presented and organized by publication date. These links will take you to the notice on the Office of the Federal Register’s website.
  3. Compare any two revisions of the regulation, word for word, by selecting a date in the menu and clicking “Show Differences”.
