In North America, general purpose area codes are area codes that are available for assignment as geographic area codes; in other words, all unassigned area codes that are not reserved for other purposes. Area codes ending in '11' are unusable due to conflict with N11 short codes such as 911 and 711. Area codes with the second and third digit the same are reserved as "easily remembered" codes such as 800/888/877/866/855/844 toll-free and 900 premium numbers. Area codes with '9' as the middle digit are reserved for future expansion. Most other unassigned area codes in the range 200 to 999 are general purpose area codes.
