To designate the facility of the United States Postal Service located at 1019 Avenue H in Fort Madison, Iowa, as the Martin L. Graber Post Office.

HR 4707 designates the U.S. Postal Service facility at 1019 Avenue H in Fort Madison, Iowa, as the "Martin L. Graber Post Office." The bill updates all official federal references - such as in laws, maps, and documents - to use this new name for the facility. It does not change operations, funding, or services at the post office. This is a naming resolution with no substantive policy impact, solely commemorating Martin L. Graber.
