You Won’t Believe What Area Code 773 Is Concealing—Beyond the Numbers When most people think of area codes, they associate them with simple geographic boundaries. But Area Code 773? It’s more than just a set of digits—it’s a hidden piece of American pop culture, mystery, and local identity. If you thought 773 just covered a small chunk of Illinois, think again. Here’s what lies beneath the surface of this seemingly ordinary code. ### The Origin of Area Code 773: A Piece of Chicago History Introduced in 1999, Area Code 773 was carved from the original Chicago area code (312) to meet growing demand for phone numbers in the bustling Windy City. Named after the 773 projection zone used by telecommunications planners, 773 quickly became the go-to area code for downtown Chicago, the Loop, and surrounding affluent neighborhoods. But unlike more widely recognized area codes, 773 never exploded into nationwide fame—until now.
