List of country calling codes

This is a list of country calling codes defined by ITU-T recommendations E.123 and E.164, also called IDD (International Direct Dialling) or ISD (International Subscriber Dialling) codes.

The telephone numbering plan for a telephone system includes an international dialing prefix, such as "00" or "011", which is added before the country calling code and is specific to the country from which the caller is dialling. Generally, as in the list below, the need for this prefix is indicated with a "+".

At a glance

Country calling codes form a prefix code; hence, they can be organized as a tree. In each row of the table below, the country codes given in the leftmost column share the same first digit; then subsequent columns give the second digit in ascending order.

In depth

While there is a general geographic grouping to the zones, many exceptions exist for various political and historical reasons. Thus, the geographical indicators below are approximations only.
