Area Code Frequently-Asked Questions
Will North America ever run out of new area codes?
It depends on whether the powers-that-be take any actions to conserve area codes by making more efficient utilization of the available pool of prefixes and line numbers within each area code. If nothing is done, says the FCC, North America has ten to fifteen years before running out of new area codes to assign. At that point the current North American Numbering Plan would become unworkable. Such drastic steps as making telephone numbers one digit longer might be necessary. Various conservation measures have been proposed to prolong the life of the NANP. In the short run, these increased efficiencies will minimize the inconvenience of constant area-code changes.
