telephone numbering plan is a plan for allocating telephone number ranges to countries, regions, areas and exchanges and to non-fixed telephone networks such as mobile phone networks. A typical dialed telephone number comprises digits that need not always be dialled and digits that must always be dialled. An open dialing plan is one in which there are different dialing arrangements for local and long distance telephone calls. This means that to call another number within the same city or area, callers need only dial the number, but for calls outside the area, an area code is required. The area code is prefixed by a trunk code (usually "0"), which is omitted when calling from outside the country.
