Making domestic calls is way different from how international calls are made. In making a domestic call, you just need to dial the National Direct Dialling (NDD) prefix (if such exists), and after that the city calling code and a local phone number. But, to make international calls you need to dial your country’s International Direct Dialling (IDD) prefix to exit from your location to international phone circuit, and then dial the destination country calling code, after that the city code and a local phone number. In some countries, the exit prefix looks like 0xx, where x marks the international carrier selection code, comprising one or more digits.
Here are all the country calling codes, international and national dialing prefixes.
