33154: The zip code for paradise. One of the most affluent zip codes in the United States, 33154 encompasses Bal Harbour, Bay Harbor Islands, Indian Creek Village, and Surfside, just north of Miami Beach. Part of the Miami-Dade miracle settlements that sprang from mangrove marshes into exclusive havens in little more than a generation, it's by far one of the most beautiful areas in all of Florida, and millions of visitors from around the world agree. Each community has an extraordinary history of dreamers, daredevils, and entrepreneurs who transformed open fields and tangled undergrowth into four of the country's most desirable destinations.
