Dialing Instructions
- Dial the International Direct Dialing (IDD) number. Countries have different numbers, or may have more than one IDD, depending on the carrier or type of service.
- Dial the Country Code. In some cases, the country code is shared among countries. For example, the United States, Canada, and much of the Caribbean and Guam use country code 1
- Dial the city/area code (if any) for the number you are dialing. Smaller countries may not use city codes or area codes, while larger countries have hundreds of them.
- Dial the phone number you are calling.
