What Do H.R., S., and H.J.Res. Mean? Reading a Bill's Number

Every measure Congress considers carries a label like H.R. 1, S. 5, or H.J.Res. 140. Those prefixes are not decoration. They tell you which chamber the measure started in, what kind of measure it is, and — most importantly — whether it can become law at all. A concurrent resolution and a bill can move through the same committees and get the same floor debate, but only one of them can change the U.S. Code. This guide is the legend for the labels you see across LegislationPatch, covering all eight types of numbered measure and how the numbers themselves are assigned.

What does the prefix tell you?

Congress numbers four kinds of measure, and each exists in a House version and a Senate version — eight labels in total. The letter or letters before the number identify the type; the chamber is signaled by whether the label starts with H (House) or S (Senate).

The single most useful thing to know is which types carry the force of law. Two do: bills and joint resolutions. Once passed by both chambers in identical text and signed by the President (or enacted over a veto), a bill or joint resolution becomes law. The other two types — concurrent resolutions and simple resolutions — never go to the President and do not make law, no matter how many votes they receive.

Bills: H.R. and S.

Bills are the standard vehicle for legislation — general law, appropriations, and program authorizations. H.R. is a House bill; S. is a Senate bill. The letters mark where the measure was introduced, not where it will end up: an H.R. bill must still pass the Senate, and an S. bill must still pass the House, before going to the President.

A common point of confusion: H.R. stands for "House of Representatives," not "House resolution." An H.R. measure is a bill. A House resolution carries the separate H.Res. prefix and is a different animal entirely (see below).

On this site, H.R. 1, the One Big Beautiful Bill Act, is a House bill, and S. 5, the Laken Riley Act, is a Senate bill. Both were signed into law.

Joint resolutions: H.J.Res. and S.J.Res.

A joint resolution requires passage by both chambers and the President's signature, exactly like a bill, and for almost all legal purposes a joint resolution and a bill are interchangeable. H.J.Res. originates in the House; S.J.Res. in the Senate. The choice between a bill and a joint resolution is largely convention: joint resolutions are typically used for continuing appropriations, single-subject or temporary measures, and resolutions of disapproval that strike down executive agency rules under the Congressional Review Act.

Joint resolutions have one notable exception to the "just like a bill" rule. A joint resolution proposing an amendment to the U.S. Constitution requires a two-thirds vote in both chambers but does not go to the President — it goes directly to the states for ratification.

H.J.Res. 140 on this site is a Congressional Review Act disapproval that cancelled a Bureau of Land Management mining withdrawal; it was signed into law, which shows that a joint resolution carries the same legal force as a bill.

Concurrent resolutions: H.Con.Res. and S.Con.Res.

A concurrent resolution requires passage by both chambers but is not presented to the President and does not have the force of law. H.Con.Res. is introduced in the House; S.Con.Res. in the Senate. Concurrent resolutions handle matters that need both chambers to agree but do not require the machinery of law: expressing the sense of Congress, setting the annual congressional budget framework, fixing the date of adjournment, or making technical corrections to an enrolled bill.

The annual budget resolution is a concurrent resolution, which is why it never goes to the President and does not itself appropriate any money — it sets a framework that later appropriations bills fill in. H.Con.Res. 40 on this site is a concurrent resolution directing the removal of U.S. armed forces under the War Powers Resolution; because a concurrent resolution is not presented to the President and does not carry the force of law on its own, its label tells you something structural about what it could and could not do.

Simple resolutions: H.Res. and S.Res.

A simple resolution is adopted by only one chamber. It is not sent to the other chamber or to the President and has no legal force outside the chamber that passes it. H.Res. is a House resolution; S.Res. is a Senate resolution. The House uses H.Res. to set the terms of debate for a specific bill (a "special rule" from the Rules Committee is a simple resolution), to create select committees, and to express the House's own views. The Senate uses S.Res. for the parallel internal business of the Senate.

H.Res. 878 on this site is a simple resolution — an action taken by the House alone, with no effect beyond the House. For a fuller treatment of how these four types differ, see our guide on joint versus concurrent resolutions.

How are the numbers themselves assigned?

Within each chamber, measures of a given type are numbered in the order they are introduced, and the count restarts at the beginning of every Congress — the two-year period that begins in January of each odd-numbered year. The House and Senate keep separate sequences, so H.R. 200 and S. 200 are unrelated measures that happen to share a number. Companion bills — identical text introduced in both chambers at once — receive different numbers because each chamber numbers on its own schedule.

Why is H.R. 1 not always the first bill introduced?

A very low number usually signals a leadership priority rather than a chronological first. Under the rules the House adopts at the start of each Congress, the first ten bill numbers (H.R. 1 through H.R. 10) are reserved for assignment by the Speaker, and the next ten (H.R. 11 through H.R. 20) are reserved for the Minority Leader. Congress.gov even lists placeholder entries labeled "Reserved for the Speaker" for numbers the majority is holding open. So H.R. 1 is the measure the majority chose to brand as its flagship — as with H.R. 1 in the 119th Congress — not simply the earliest to reach the hopper.

What about the Public Law number?

When a bill or joint resolution is enacted, it receives a Public Law number that is separate from its bill number. "Pub. L. 119-82" means the 82nd law enacted by the 119th Congress. The Public Law number is assigned in order of enactment across both chambers, so it is the durable citation for a statute once it exists — while the H.R. or S. number identifies the measure as it moved through the process.

Reading the labels on this site

LegislationPatch labels every measure with its official prefix and number, sourced from Congress.gov. When you see H.J.Res., you are looking at something that can become law; when you see H.Con.Res. or H.Res., you are looking at something that cannot, regardless of the vote. That distinction is the fastest way to gauge what a measure could actually do. To see how these measures move from introduction to enactment, read how a bill becomes law, and to read the text of a measure once you have found it, see our guide on how to read a federal bill.
