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.
What this guide does not do
It does not check a live number, identify an owner or carrier, rate spam, or locate a device. Country rules appear on country pages only when they come from a reviewed source. Sources and review dates →
