This article is about the dialing codes to select an international telephone circuit when dialing an international call. For the telephone country codes, see list of telephone country codes.
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, 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.
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.
00xx, where xx is a two-digit carrier selection code:
Australia, alongside the standard prefix 0011 for the default carrier
Finland, alongside the standard prefix 00 for the default carrier, carrier selection code consisting of either a single digit (1–4, 6–9) or three digits (511–599)[1]
^ abcKenya, Tanzania and Uganda each can be called from the other two using special short codes: 005 to call Kenya, 006 to call Uganda and 007 to call Tanzania. The shortcode is followed directly by a local number.
