Here's 1 cause: I live about 1.5 miles from the 40222 post office. My zip is 40223 which is about 5 miles away. BUT if I need to go to the post office to pick up my mail I have to go to the 40243 post office about 7 miles away. go figure ! 40222 = Lyndon Ky. 40223 = Anchorage Ky. 40243 = Middletown Ky. I'm in Moorland Ky. ??????
