Area Code 773 History and Coverage

Assigned in 1996, 773 was created through a geographic split of the long-standing 312 territory as the supply of available telephone numbers faced increasing demand. The older code was among the original North American Numbering Plan assignments made in 1947, marking its long use in northeastern Illinois.

By the 1990s, demand was shaped by more than resident counts. Additional household lines, growing office systems, fax machines, pagers, and cellular service all required separate numbering resources. Dividing the territory allowed the established 312 code to remain in the Loop and nearby central business districts while a separate designation handled the outer neighborhoods.

An additional area code called 872 became an overlay in 2009 for the two existing 312 and 773 area codes, thus creating another pool of telephone numbers for the area without any need for geographic separation. In terms of the 773 territory, it covers the areas bordering to Lake Michigan in Rogers Park, the west neighborhoods until the city boundaries, and the southern regions which border Cook County.
