List of country calling codes - Wikipedia, the free encyclopedia
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 specified with a "+". 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.Imagine a home that heats itself, that provides its own water, hat grows its own food. Imagine that it needs no expensive technology, that it recycles its own waste, that it has its own power source. And now imagine that it can be built anywhere, by anyone, out of the things society throws away.
