Country codes and international calling codes

Two code systems appear on forms and in phone numbers. ISO 3166-1 gives every country a two-letter code (AE, SA, GB) used in domain names, addresses and passports, and a three-letter code (ARE, SAU, GBR) used on machine-readable passport lines, in sport and in some databases. The ITU-T E.164 calling code (+971, +966, +44) is what you dial before a national number. The first table covers all 193 UN member states; the second adds the observer states and 50 commonly needed territories.

Several places share a calling code. The North American Numbering Plan uses +1 for the United States, Canada and about twenty Caribbean countries and territories, distinguished by the three-digit area code shown after +1. Russia and Kazakhstan share +7; the UK Crown Dependencies use +44; French overseas departments have their own codes (+590, +594, +596, +262) while Saint Barthélemy and Saint Martin share +590 with Guadeloupe.

Kosovo has no ISO code; XK is the widely used provisional code and +383 its calling code since 2017. Vatican City uses Italian numbers (+39 06 698) and also holds +379, which is not in service. Filter the table by country name, code or region.
