About the 847 region
847 covers North suburbs in Illinois, including Algonquin, Antioch, Arlington Heights, Bannockburn and Barrington. The code has been in service since 1996.
As the North suburbs region grew, 847 ran low on available numbers, so 224 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.
