Same house number, but different street. Both street names started with the same first two letters. Have a feeling he punched in the house number, and first letter or two and just selected the first option that came up on the screen. Wouldn't have known if the guy living at the other address hadn't driven the packages over a couple times. I had one package for his address that I drove over to deliver too. Eventually we either got a different FedEx driver or he corrected his mistake.
