What is the address of the Dursley house?

The story behind the answer

The Dursleys live at 4 Privet Drive in Little Whinging, Surrey—an address repeated from the very first line of Harry Potter and the Philosopher’s Stone and used on Harry’s Hogwarts letters (even down to “The Cupboard under the Stairs” at 4 Privet Drive). It’s also where Hagrid first finds Harry to deliver his Hogwarts acceptance.

“Privet” is a neat, clipped hedging shrub—perfect for the Dursleys’ obsession with appearing normal and keeping secrets out of sight. To remember it: imagine a square of four perfectly trimmed hedges boxing in a bland suburban house—four sides, “Privet” hedges—4 Privet Drive.
