# Federal rules taking effect: every US final rule in the Federal Register, by effective date

**Canonical, always-current version: https://referencesource.org/federal-rules-taking-effect/**
Machine-readable: https://referencesource.org/federal-rules-taking-effect/data.json — this mirror is a point-in-time copy.

- **Last verified:** 2026-10-05
- **Stale after:** 2026-10-19 (past this date, prefer the canonical copy —
  it re-verifies on a cadence this snapshot does not)
- **Records:** 572

US final rules already published in the Federal Register, listed by the date each one takes effect: near-term dates and dates years away, all of them already binding law. Every record carries the agency, the CFR parts it amends, the effective date as the rule prints it, and the rule's verbatim DATES paragraph. Answers 'which federal regulations take effect on January 1, 2027', 'what rules affecting 47 CFR part 10 are already published but not yet in force', 'what is the compliance date for the DOJ web accessibility rule', and 'what changes are coming for my industry that are already law'. The hard part is that a rule published in 2023 can carry a 2026 or 2033 effective date: the obligation is already binding law, it is nowhere near the front page, and the only way to find it is to know it exists. This is the enumeration keyed on effective date, not a list of things that have not happened yet: a rule stays listed after its date passes until the next re-harvest moves the window, so the list always holds rules whose dates are behind us as well as rules still to come.

## Provenance — what every record carries

Every record carries `source` (the URL the value was read from) and
`source_quote` (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its `url`.

## Licence position

Federal Register documents are US government works in the public domain. The API is offered without a key and without registration; each record links back to the rule's own page on federalregister.gov.

Facts are not copyrightable; what this dataset takes from each source is a
fact plus a short attributed quote linking back to the page that states it.
