We live on a street that is a dead end on both ends. It is fed by two other streets that dead end into it. One other street in the area dead ends into our street and one of the feeder streets.
To top it off, ours is a Drive, and within the same ZIP code, actually only a block or two away, is a Court with the same name. The numbering is different so there’s not a similar house number to ours on the Court, but if people address using our house number, we get the mail for the Court. Usually it’s junk mail so I feel safe in tossing it if it’s delivered to us. But if it looks important I wind up delivering it to the lady who lives on the Court. She says she’s never had any of our mail delivered to her.
The postman says that even though he knows there’s no such address as our house number on the Court, and even though he knows that the numbering system on the Court was changed to avoid the similarity, that if the item has our address on it, he has to deliver it to us. I don’t think our situation is unique since there are any number of Courts, Circles, Places, etc., that adjoin Streets, Avenues, Drives, Parkways, Boulevards, etc.
