International Call Prefix

An international call prefix or dial out code is a trunk prefix used to select an international telephone circuit for placing an international call. The prefix must be dialed before the country calling code and the destination telephone number. It is synonymous with international access code or exit code.

The International Telecommunications Union (ITU) recommends the sequence 00 as a standard for an international call prefix, and this has been implemented by many countries, but not all of them.[1]

When phone numbers are published for use abroad they typically include the country calling code, but 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.[2]

Many phones allow this "+" to be entered in their saved number lists, often by holding down the '0' key (most GSM mobile phones) or with two consecutive presses of the * key. When making a call the system then automatically converts the "+" to the correct international prefix, depending on where the phone is being used, which enables callers to use the same stored number from any country.[3]

Example

  • If a caller in the USA or Canada wants to call the Mayor of Dunedin, New Zealand, he would dial 011 64 3 477 4000. (The generic international call prefix for NANPA countries is 011, then the country code for New Zealand is 64, the area code for Dunedin is 3, and the local number for the Dunedin City Council is 477 4000).
  • If a caller in Japan wants to call the same number, he would dial 010 64 3 477 4000.
  • If a caller in Australia wants to call the same number, he would dial 0011 64 3 477 4000.
  • If a caller in the UK, China or any other country using the ITU recommended 00 prefix, wants to call the same number he would dial 00 64 3 477 4000.

Variations

Some telecommunications service providers or mobile network operators (wireless carriers) have different international call prefix codes which callers or subscribers can use to route calls through specific networks, sometimes with special pricing arrangements.

Many countries also provide alternative dialling arrangements for calls to neighbouring countries.[4]

Some of these variations from the generic codes are shown in the list below (but may be out of date).
