About International Calling Codes
Country calling codes are telephone prefixes used when dialing a phone number in another country. They follow the ITU-T E.164 international numbering standard. To place an international call, dial your country’s international exit code (e.g. 011 in the US, 00 in the UK), followed by the destination country calling code, and then the local phone number minus any trunk prefix.
This directory covers all 233 countries across 5 world regions. Each entry includes the ITU-T country code, ISO 3166-1 codes, capital city, trunk prefix, and notable area codes where applicable.
