The financially-troubled agency announced Tuesday that it will study more than 3,600 offices, branches and stations for possible closing. Some sites might be replaced by stores, libraries or government offices that offer postal services.
Most of the targeted sites are in rural areas and have low volume. The Indiana list includes branches in the southwestern towns of Mackey and Stendal, Mackey has about 100 residents, and Stendal's population is about 250.
The postal service lost $8 billion last year as more customers shifted to online mail and the recession cut advertising mail. It currently operates nearly 32,000 retail outlets across the country.
