Country calling codes: lookup and full list

How country calling codes work

A country calling code is the one-to-three digit prefix that routes an international call or SMS to the right country. It follows the international prefix you dial to leave your own country (+ on a mobile, 00 in most of the world, 011 from North America). The codes were assigned by the ITU in zones: 1 for North America, 2 for Africa, 3 and 4 for Europe, 5 for Latin America, 6 for Oceania and Southeast Asia, 7 for Russia and Kazakhstan, 8 for East Asia and 9 for South and West Asia.

Codes never overlap: no code is the prefix of another, which is what lets a phone network read +1, +44 or +353 without knowing in advance how long the code is. Within a country the rest of the number follows a national plan, which is why the total length varies between countries even though E.164 caps it at 15 digits.

Codes shared by several countries

• +1 is the North American Numbering Plan: the United States, Canada and about 25 Caribbean and Pacific territories. The three digits after +1 are an area code, and for territories like Jamaica (+1 876) or Puerto Rico (+1 787, +1 939) the area code is fixed, which is how the table lists them.
• +7 is shared by Russia and Kazakhstan; Kazakh numbers start with +7 6 or +7 7.
• +44 covers the United Kingdom together with Guernsey, Jersey and the Isle of Man, which use UK-style area codes.
• +61 is Australia plus Christmas Island and the Cocos Islands; +47 is Norway plus Svalbard; +358 is Finland plus Åland; +39 serves Italy and in practice Vatican City.
• French overseas territories mostly have their own codes (+590, +594, +596, +262, +687, +689), while Saint Barthélemy and Saint Martin share +590 with Guadeloupe and Mayotte shares +262 with Réunion.

Calling codes and SMS verification

When an app asks for your phone number it usually shows a country dropdown and expects the national part only. If the form shows +44 and you type 07911 123456, many apps silently keep the 0 and send the code nowhere. Type 7911 123456 instead, or paste the full E.164 number into our formatter to see what the app should receive. When you rent a temporary number from the catalog, the country code is displayed next to the number so you can select the matching country in the app.

Apps also use the code to decide whether they serve a market at all. Some refuse sign-ups from certain country codes or ask for extra verification; our requirements index notes those cases per app.

About this list

Names follow the ISO 3166 short English names, with a few common forms kept for readability (Czechia, Eswatini, Côte d'Ivoire). Kosovo appears with its provisional code XK and its calling code +383. The list reflects ITU-T E.164 country code assignments; names follow ISO 3166 short names in English. It was last reviewed on 2026-10-24; corrections are welcome at [email protected].
