Country Codes & International Calling Codes

How country codes work

Every country has an international calling code of one to three digits, assigned by the International Telecommunication Union (ITU). To call abroad you dial your country's exit code (00 in most of the world, 011 in North America, 0011 in Australia) or simply + on a mobile, then the country code and the national number without its leading zero.

The nine world numbering zones

The first digit of a code tells you the region:

• 1 — North America & Caribbean (NANP): 25 countries, e.g. American Samoa, Anguilla, Antigua and Barbuda, Bahamas and Barbados
• 2 — Africa & a few Atlantic islands: 60 countries, e.g. Algeria, Angola, Aruba, Benin and Botswana
• 3 — Europe: 35 countries, e.g. Albania, Andorra, Armenia, Belarus and Belgium
• 4 — Europe: 15 countries, e.g. Austria, Czechia, Denmark, Germany and Guernsey
• 5 — Latin America: 27 countries, e.g. Argentina, Belize, Bolivia, Brazil and Chile
• 6 — Southeast Asia & Oceania: 30 countries, e.g. Australia, Brunei, Christmas Island, Cocos (Keeling) Islands and Cook Islands
• 7 — Russia & Kazakhstan: 2 countries, e.g. Kazakhstan and Russia
• 8 — East Asia & special services: 11 countries, e.g. Bangladesh, Cambodia, China, Hong Kong and Japan
• 9 — Middle East, South & Central Asia: 30 countries, e.g. Afghanistan, Azerbaijan, Bahrain, Bhutan and Georgia

Shared codes

Some codes are shared. +1 covers 25 countries and territories of the North American Numbering Plan — the United States, Canada and much of the Caribbean — each with its own area code. +7 is shared by Russia and Kazakhstan, and +44 by the United Kingdom and its Crown Dependencies.
