Area code 773 serves the neighborhoods of Chicago outside the downtown core, including areas such as Wrigleyville, Logan Square, Englewood, and Albany Park. It was created in 1996 when it split from area code 312, which now serves only the central business district. In 2009, area code 872 was added as an overlay to both 312 and 773 to provide additional number availability. Ten-digit dialing is required throughout the region. The 773 area code has become a strong symbol of Chicago’s residential and cultural neighborhoods, distinct from the business-focused 312. It is often used in local branding, streetwear, and music, representing the working-class and creative spirit of the city’s outer areas.
