This is a list of country calling codes needed to access international
telephone services. The numbers are assigned by the
International Telecommunications Union in standard
E.164.
The numbers are a prefix code so that no number has an initial segment that is an existing shorter number. This code is used to dial into to country specified; each country also has an international call prefix used to dial out of the country.
Some countries (for example, Germany) require the caller to omit the leading 0 of the national area code. For example, to call the subscriber in Germany with the national telephone number 089 123456, somebody outside of Germany would have to dial +49 89 123456, where the + stands for the international call prefix. However, this does not apply to all countries (e.g. Italy).
