Area codes provide a level of organization for telephone numbers, allowing a shorter number to be dialed for local and nearby calls than for cross-country calls. Not all countries use area codes.
In some areas, you must dial the area code, even for local calls in the same area code. In countries like Spain, France, and Italy, all calls must be dialed with the full national number. That requirement loosens some restrictions on assignable numbers.
In the United States and Canada, in places that have overlay area codes (two or more area codes serving the same or overlapping geographic areas), you must dial the area code on all calls, for two reasons. One is to reduce the potential for customer confusion, since it may not be immediately obvious which area code a particular telephone belongs to. The other is to reduce the competitive disadvantage for new local phone companies, since they are more likely to have numbers in the newer area code(s) than the established phone company.
