History of the 847 Area Code
The 847 phone area code was introduced in 1996 when it was split from the original 708 areas codes due to rapid population growth and increased demand for telephone lines. During the 1990s, mobile phones, fax machines, and internet connections expanded quickly, and northern Illinois required additional numbering capacity. Later, authorities added an overlay area code (224) to support continued growth.
The 224 Overlay: Why 10-Digit Dialing Is Required
Shortly after its creation, the 847 area code began experiencing the same pressures that had led to its birth. Area code was involved in the first trial of telephone number pooling in the United States in June 1998, to avert central office code exhaustion. Nevertheless, within only five years, 847 was already close to exhaustion due to rapid growth in telecommunications services in the Chicago suburbs and the proliferation of cell phones and pagers. On January 5, 2002, authorities assigned area code 224 as an overlay for area code, which required ten-digit dialing in all affected communities.
Time zone
The 847 area code time zone is located in the Central Zone (CT) of the United States. This time zone covers the central part of the country and follows Central Standard Time (CST, UTC−6) during the winter months. However, during daylight saving time, it switches to Central Daylight Time (CDT, UTC−5) in the summer months. As a result, local time in the 847 region is adjusted forward by one hour during warmer months. In this way, the area makes better use of daylight and supports longer evening daylight hours.
