Notes

1. To call or text a foreign telephone number you must use the international prefix of the country you are dialing from. Also known as international direct dialing (IDD) codes or exit codes, these prefixes are set to redirect calls or text messages to phone numbers registered in other countries. Nowadays international prefixes and the plus sign (+) can be used interchangeably. The plus sign is preferred by many because it works regardless of the country you are calling from.
2. Country codes are used to dial phone numbers internationally. Each country has an assigned code of its own. In order to dial an international phone call you must always use a country code before the actual subscriber telephone number.
3. National trunk prefixes are codes used to place calls within a certain country. They are left out when dialing in from abroad.
