List of international call prefixes

This is a list of international dialing prefixes used in various countries for direct dialing of international telephone calls. These prefixes are typically required only when dialling from a landline, while in GSM-compliant mobile phone (cell phone) systems, only the symbol + before the country code may be used irrespective of where the telephone is used at that moment; the network operator provides the access codes automatically.
