Many post offices and branches under review are in rural areas and provide little revenue. In fact, 84 percent of the locations on the list take in less than $27,500 in annual revenue and have less than two hours of work a day, according to Dean Granholm, the Postal Service's delivery and operations vice president.
Savings from the closings could be as much as $200 million. But it also means potentially massive layoffs: As many as 3,000 postmasters, 500 supervisors, and 500 to 1,000 clerks could be let go, according to Mr. Granholm.
The first closings are expected by January 2012.
