To designate the facility of the United States Postal Service located at 1157 West Mission Avenue in Escondido, California, as the "Captain E. Royce Williams Post Office Building".

This bill renames a U.S. Postal Service facility in Escondido, California, to honor Captain E. Royce Williams. It officially designates the building at 1157 West Mission Avenue as the "Captain E. Royce Williams Post Office Building" and updates all federal references to the location to use this new name. The change affects only official documents and records, not the building's operations or services. This is a purely administrative naming action with no policy or funding implications.
