List of international call prefixes
The International Telecommunication Union
(ITU) recommends the sequence 00 as a standard for an international call prefix, and this has been implemented by most countries, but not all of them.
Some countries use the 00 prefix which is followed by the international carrier code.
When phone numbers are published for use abroad, they typically show a plus sign (+) prefix in place of any international call prefix, to signify that the caller should use the prefix code appropriate for their country.
Many phones allow the plus sign to be entered in their saved number lists, often by holding down the zero (0) key (most GSM
mobile phones) or with two consecutive presses of the star (*) key. When making a call, the system then automatically converts the plus sign to the correct international prefix, depending on where the phone is being used, which enables callers to use the same stored number when calling from either their own country or any other.
Many countries also provide alternative dialling arrangements for calls to neighbouring countries.
Some of these variations from the generic codes are shown in the list below (but may be out of date).
