Notation Key

Green text indicates an overlay that has not yet taken effect. An asterisk (*) indicates an overlay code that covers more than one original code area. (For example, area code 872 in Chicago is an overlay on both area code 312 and area code 773.) If the (Old) area code and the Old (& New) are all green, the region has not yet implemented an overlay. If the old code is black and the overlay codes are shown as, for example, Old & New (& Newer), the region has an overlay and is planning to add an additional overlay code as shown.
