List of country calling codes
This article is a travel topic
When calling a phone number in another country, there is usually a prefix you have to dial to indicate that you're placing an international call; this varies by country. After that international dialling prefix, you must dial the international country code for the country you are calling, followed by the local number. This is a list of those country codes.
Note: The United States and its possessions, Canada, and several Caribbean nations technically share the international calling code 1, with each state (or parts of states), province, territory, or island nation given its own three-digit "area code". The following list includes the area codes for such nations outside the US and Canada, as well as those of US possessions outside of the United States proper.
Before dialling the area code, you usually have to dial an international prefix. This is so that the country code won't be confused with the first few digits of a local or national telephone number. Here is a list of common international prefixes that need to be dialed before the country code and the rest of the phone number:
Alternatively, if you have a mobile phone, you can dial the '+' key first before the country code regardless of which country you are calling from.
