Quite a few Marvel characters have defined addresses, especially if they operate within New York City. The Baxter Building is located at the corner of 42nd Street and Madison Avenue in Manhattan — unless it's recently been hijacked into space. If you're looking to drop by Dr. Strange’s residence, that's 177A Bleecker Street in Greenwich Village. Peter Parker grew up at 20 Ingram Street, in the Forest Hills section of Queens.
In the Harry Potter books, the Dursleys' house is frequently identified in the narrative as "number four, Privet Drive." The street name "Privet Drive" was possibly chosen to reflect the Dursleys' pride in their house, and that they are ordinary folk, with no connections to nonsense such as magic. Some of the letters brought by owls are very specific indeed with the addresses, saying "Mr. H. Potter, the cupboard under the stairs, 4 Privet Drive".
In Finding Nemo, the diver who took Nemo has his name and address written on the mask that fell overboard: P. Sherman, 42 Wallaby Way, Sydney. It provides Marlin with the only clue as to the whereabouts of his son. Dory, who suffers from short-term memory loss, is surprised that she is able to remember the full address, and recites it constantly on their way to Sydney.
“I'm going to P. Sherman, 42 Wallaby Way, Sydney. Where are you going? I'm going to P. Sherman, 42 Wallaby Way, Sydney. If you're askin' where I'm goin'. I'll tell you that's where I'm going. It's P. Sherman, 42 Wallaby Way, Sydney. Where? I'm sorry, I didn't hear you. P. Sherman, 42 Wallaby Way..."
