Abstract
A system for updating area code information in predetermined telecommunications devices and networks as newly created area codes are implemented. Area code lists may be updated automatically and without the need for human intervention or manual reprogramming. A message receiving unit monitors the telephone connection and determines whether a 'new area code' message is being transmitted by the telephone company central office or carrier. A message decoding unit decodes the transmitted message into a required format for a predetermined device. An update unit enables the area code lists to be automatically updated in the predetermined device if a list comparator determines that the area code does not exist in the lists.
