Las Vegas is one of the most visited cities in the world, and yet its most famous destination—a 6.8km boulevard of extravagantly themed casinos known as “The Strip”—is actually located outside of Las Vegas city limits. To add to the confusion, the city’s true borders are jagged and full of small holes. And, according to the U.S. Postal Service, residents and businesses of the surrounding unincorporated communities of Clark County may still claim a Las Vegas address. As a result, the City of Las Vegas asks people to verify that their address is inside city limits before requesting city services.
