History of Area Code 224
Area code 224 entered service on January 5, 2002, as an overlay for area code 847. Area code 847 entered service on January 20, 1996, after a split from area code 708, which had previously covered a much larger part of the Chicago metropolitan area.
The 224 overlay added new telephone number combinations as demand increased in the northern Chicago suburbs. Unlike a split, the overlay did not divide the existing territory or require existing 847 customers to change their numbers. Area codes 224 and 847 cover the same geographic region.
