House Bills and Resolutions: A bill originating in the House of Representatives is designated by the letters ‘H.R.’ followed by a number that it retains throughout all its parliamentary stages.

Senate Bills and Resolutions: A Senate bill is designated by the letter ‘S.’ followed by its number

Joint Resolutions are designated H.J. Res. or S.J. Res. and are followed by a number. They become law after approval by both houses and the President. There is no practical difference from bills, but joint resolutions generally deal with more limited matters.

Concurrent resolutions, are designated H.Con. Res. or S.Con. Res., and followed by a number. They deal with matters that affect the operations of both chambers and must have both chambers’ approval, but do not require Presidential support.

Simple resolutions are designated H.Res. and S.Res., followed by a number.  A simple resolution addresses matters entirely within the prerogative of one house.

  • the designation
  • the number of the bill
  • the name of the body in which it was introduced
  • date of introduction
  • the name of the member who introduced it
  • the Committee to which it was referred.

The legislative process in Congress is described in the booklet, How Our Laws Are Made by Charles W. Johnson (1998). An updated version (2007) is available online from the Library of Congress. From Section IV:

A bill is the form used for most legislation, whether permanent or temporary, general or special, public or private.

The form of a House bill is as follows:

For the establishment, etc. [as the title may be].
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That, etc.

The enacting clause was prescribed by law in 1871 and is identical in all bills, whether they originate in the House of Representatives or in the Senate.

House and Senate versions of the same bill often differ because each chamber amends the bill before enacting it.
