Like postal addresses, international numbers have two basic telephone number representations. One is for domestic use; The other is international. To make matters more complicated, international numbers often take different forms according to different callers.

An international number consists of a national number and a domestic valid number. If a country or a group of overseas territories is represented by a country number in principle, the country number should be at least 3 digits for more than 100 geographical units on the earth. On the other hand, in order to shorten the digits of international numbers as much as possible, the country number is displayed on the right, and its digits should be different according to the size of each country.

Countries in the world are grouped into international number areas according to their geographical location, and the distribution of international number areas is also shown on the right. Most of the total digits of international numbers can be set to 1 1 digits.
