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[citation needed] irrespective of where the telephone is used at that moment; the network operator provides the access codes automatically.
The following is a non-exhaustive list of countries that optionally allow for carrier selection in addition to using the standard prefix listed in the preceding section.
