More than 3,600 locations nationwide are being considered for closure, including a bunch in California (via NBC4). The new idea is to replace many of the branches with postal service centers in stores, libraries or government offices. From the WSJ:
The agency hopes to begin opening as many as 2,500 "village" post offices by the fall. Essentially, the postal service would contract with small businesses in towns that are losing a post office, to offer mail services such as selling stamps and accepting packages. The arrangement would be convenient for consumers who may already be shopping in these places and would also bring more foot traffic to local merchants, Mr. Donahoe said. "It's a good opportunity for small businesses," he said. "Many general stores are hanging on for dear life out there with the recession and a lot of other issues."
The list after the jump only means that a location is being considered for closure.
