List of country calling codes (Iearth)

Jump to navigation Jump to search
Worldwide distribution of country calling codes. Regions are coloured by first digit.

Country calling codes or country dial-in codes are telephone number prefixes for reaching telephone subscribers in the networks of the member countries or regions of the Coalition Telecommunications Union (CTU). The codes are defined by the CTU Standardisation Board. The prefixes enable international direct dialing (IDD). Countries are divided into regions, which defines the first number in the calling code, and subsequent numbers are defined by geographical position and population sizes, with larger countries generally having simpler codes.

Country codes are a component of the international telephone numbering plan and are necessary only when dialing a telephone number to establish a call to another country. On cellular networks, the prefix may automatically be inserted when the user prefixes a dialed number with the plus sign.

Tree list

Country calling codes are prefix codes and can be organized as a tree graph. In each row of the table, the country codes given in the left-most column share the same first digit; then subsequent columns give the second digit in ascending order. The countries are marked with their CTU country codes.
