A bill to amend title 39, United States Code, to prohibit the U.S. Postal Service from merging post office operations without the approval of persons regularly served by such post offices.

Prohibits the Postal Service from closing any post office for the purpose of: (1) merging the operation of such post office with the operation of another; (2) changing its name or ZIP code; or (3) reducing its services without the approval of a majority of patrons of such post office who respond to a referendum conducted pursuant to this Act. Requires the postmaster of the affected facility, in the event such change is planned, to distribute a referendum proposing such action to persons regularly served by such post office and to receive responses during the following 60-day period.
