Chicago will officially start use of its third area code, 872, this week.
The Illinois Commerce Commission says the city will begin use of the new area code Saturday. The commission also says Saturday is the first day of 11- digit dialing in the city. That means that residents will no longer be able to dial seven digits to reach a local number inside their same area code.
The 872 code joins the 312 and 773 area codes within Chicago city limits.
The city Department of Business Affairs and Consumer Protection advises residents and businesses to prepare for 11-digit dialing by making sure equipment with automatic dialing features is programmed with all 11-digits for each telephone number. AP
