How to dial
internationally.
A call is a sequence: leave the local network, add the country calling code, then dial the number the way that country writes it.
The parts of a call
The digits that start an international call from where you are. Mobile phones often accept a + as a shortcut.
Routes the call to a country, a territory, a group of countries or a service.
The rest of the number, after any domestic adjustment for that country.
Four steps
Start with the exit code
Use the prefix required by the network you are calling from. Mobile phones often accept a plus sign as the shortcut.
Add the country calling code
It names the destination numbering plan. Some codes are shared, so the digits after it can matter.
Apply the national rule
Some domestic leading digits are dropped when dialing from abroad; others are kept in specific cases. Each country page states the rule only where it has been verified.
Dial the rest of the number
Dial the area code, if there is one, and then the subscriber number.
The leading digit
Many countries write numbers with a digit or sequence in front for calls inside the country, called a trunk prefix. It is not the country code, and it is often left out after the country code. Exactly how it is handled depends on the country and the type of number.
Format examples
Structure only. These are not real numbers. The exit prefix shown applies only where the calling network uses it.
| Format | Structure |
|---|---|
| International format | + xx xxxxxxxxx |
| From a fixed network | 00 xx xxxxxxxxx |
| With an extension | + xx xxxxxxxxx, ext. xxx |
International format: plus, country calling code, national number. Fixed network example: exit prefix 00, country calling code, national number. International format with an extension after connection.
