Area Code 872
Area code 872 is a North American Numbering Plan overlay of telephone area codes 312 and 773 in Chicago, Illinois, and entered service on November 7, 2009. Its overlay status means it is assigned only to new numbers in the area and not to existing numbers using the 312 and 773 area codes. It is the third overlay area code in the region and the tenth area code to serve northeast Illinois. As early as 1998, Neustar, which administers the North American Numbering Plan, had recommended a third area code for Chicago, estimating that 312 and 773 would both exhaust by 2001. However, the Illinois Commerce Commission implemented a series of conservation measures that staved off the need for a new area code. By 2008, a combination of population growth and a large growth in cell phone usage forced the implementation of 872. With the implementation of 872, all local calls in Chicago must be dialed with the full 11-digit phone number ( 10 digits from cell phones). The Illinois side of ...

Lake Michigan
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume () and the third-largest by surface area (), after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the wide, deep, Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake. Lake Michigan is the world's largest lake by area in one country. Located in the United States, it is shared, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan. Ports along its shores include Milwaukee and the City of Green Bay in Wisconsin; Chicago in Illinois; Gary in Indiana; and Muskegon in Michigan.

North American Numbering Plan Administration
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sector by the Federal ...

Area Codes 815 And 779
Area codes 815 and 779 are telephone area codes for most of northern Illinois outside the Chicago and Quad Cities areas.

It was split in 1957, when most of its western portion, including most of the Illinois side of the Quad Cities, was combined with part of the northern portion of area code 217 to form area code 309. In preparation of an overlay area code (779), all calls from the 815 area needed to be dialed with an area code beginning on February 17, 2009. A month later, the 779 code was activated.
